Myopia Guide by Gurjeet Jutley
May, 2024

As we observe Myopia Awareness Week from May 13th to 19th, it gives us an opportunity to explore this prevalent eye condition affecting millions worldwide. In this article, Gurjeet Jutley, Consultant Ophthalmologist and Eye Surgeon in Oxford, aims to raise awareness and provide in-depth insights into the diagnosis, causes, symptoms, and management of myopia.

What is Myopia?

Myopia, commonly referred to as near-sightedness or short-sightedness, is a refractive error where distant objects appear blurry while close objects remain clear. By 2050, it’s estimated that half the global population, around five billion people, will be affected by myopia. This condition can significantly impact daily activities such as driving, reading, and watching television. Myopia is typically diagnosed during routine eye exams, where visual acuity and refraction tests are performed to assess the extent of near-sightedness.

Causes and Risk Factors

Myopia occurs when the eyeball is too long, resulting in a mismatch between the focus point of the lens and the position of the retina. Genetic predisposition plays a significant role, with myopia often running in families. Additionally, lifestyle factors such as prolonged close-up activities, increased screen time, and limited outdoor exposure during childhood have been linked to the development of myopia. Environmental factors, including urbanisation and educational demands, also contribute to the rising prevalence of myopia worldwide.

Symptoms and Diagnosis

Symptoms of myopia in children may include sitting close to screens, frequent eye rubbing, and complaints of tiredness or headaches. Adults may experience difficulty reading distant objects, eye strain, headaches, and ‘squinting’. Diagnosis involves comprehensive eye exams, including visual acuity and refraction. Early detection and intervention are crucial for effectively managing myopia and preventing further vision impairment.

Complications and Management

Severe myopia can increase the risk of complications such as glaucoma, retinal detachment, neovascular membranes and cataracts. Myopia management aims to reduce progression, particularly in young age, and prevent sight-threatening conditions. Options include corrective eyeglasses, contact lenses, and specialty lenses proven to slow myopia progression. Orthokeratology, a non-surgical treatment involving the use of specially designed contact lenses to reshape the cornea, has shown promising results in controlling myopia progression in children. Laser visual correction, refractive surgery or clear lens extraction may be considered for adults with stable prescriptions.

Prevention and Lifestyle Changes

While there is no cure for myopia, certain lifestyle changes can help manage the condition and reduce progression. Limiting screen time, maintaining proper reading distances, taking regular breaks, spending time outdoors, and ensuring well-lit environments can all contribute to reducing myopia progression. Regular eye exams are essential for early detection and timely intervention. Myopia management programs, tailored to individual needs, play a crucial role in preserving vision and ensuring optimal eye health.

Let’s raise awareness and take proactive steps towards managing myopia during Myopia Awareness Week and beyond.

Nourish Your Vision: A Guide to Nutrition for Healthy Eyes

In today’s fast-paced world, it’s easy to overlook the importance of proper nutrition for maintaining optimal eye health. As a consultant ophthalmologist specialising in cataract and glaucoma procedures, Mr. Gurjeet Jutley understands the critical role that nutrition plays in supporting vision. In this article, Mr Jutley explores the connection between nutrition and eye health, focusing on key nutrients that promote healthy eyesight and suggesting dietary sources to incorporate into your daily meals.

Why Nutrition Matters for Eye Health

The eyes are complex organs that rely on a variety of nutrients to function optimally. A diet rich in vitamins, minerals, antioxidants, and omega-3 fatty acids can help protect against a variety of conditions, including age-related macular degeneration and dry eyes. By nourishing your body with the right nutrients, you can support the health of your eyes and potentially reduce the risk of developing certain eye conditions.

Essential Nutrients for Eye Health

Vitamin A: Essential for maintaining good vision, particularly in low light conditions. Foods rich in vitamin A include carrots, sweet potatoes, spinach, kale, and liver.
Vitamin C: Acts as an antioxidant, protecting the eyes from oxidative stress and reducing the risk of cataracts and age-related macular degeneration. Citrus fruits, strawberries, bell peppers, and broccoli are excellent sources of vitamin C.
Vitamin E: Another powerful antioxidant that helps protect the eyes’ cells from damage caused by free radicals. Incorporate foods like almonds, sunflower seeds, spinach, and avocado into your diet to boost your vitamin E intake.
Omega-3 Fatty Acids: Essential for maintaining the structural integrity of the retina and supporting overall eye health. Fatty fish such as salmon, mackerel, and sardines are excellent sources of omega-3s, as are flaxseeds, chia seeds, and walnuts.

Tips for Incorporating Eye-Healthy Foods into Your Diet

Starting with a nutritious breakfast that includes fruits high in vitamin C, such as oranges or strawberries, and a handful of nuts rich in vitamin E is not only recommendable, but also delicious.
Incorporate leafy greens like spinach, kale, and collard greens into your salads, smoothies, or stir-fries for a boost of vitamin A and other essential nutrients.
Snack on raw vegetables like carrots, bell peppers, and celery sticks dipped in hummus or Greek yogurt for a satisfying and eye-friendly snack.
Include omega-3-rich foods like salmon, tuna, or flaxseed oil in your meals at least twice a week to support healthy vision.

If you’re experiencing any vision-related concerns or are interested in learning more about how to maintain healthy eyesight through nutrition, don’t hesitate to reach out to Mr. Jutley, in Oxford. With his extensive experience in cataract and glaucoma procedures, Mr. Jutley is committed to helping you achieve and preserve optimal vision for years to come.

Incorporating nutrient-rich foods into your diet is a simple yet powerful way to support the health of your eyes. By prioritising nutrition and consulting with a knowledgeable eye care professional like Mr. Jutley, you can take proactive steps towards safeguarding your vision and enjoying a lifetime of healthy eyesight.

Spain is one of the most beautiful holiday destinations and a must visit to enjoy the sun. While these provide plenty of opportunities for relaxation, when the mercury ticks too high, it can create problems. With climate change, summers in Spain are becoming even hotter and longer.

If you’re prone to dry eyes, then this can present significant challenges. The combination of intense heat, glaring sunlight, and increased reliance on air conditioning, can all exacerbate dry eye symptoms.

In this blog, Gurjeet Jutley examines the topic of dry eyes and advises on what preventative measures you can take during the extreme heat.

 

Understanding Dry Eyes 

Dry eye syndrome is caused when either eyes do not produce enough tears or tears evaporate rapidly. This leaves eyes feeling dry and irritated and can potentially lead to blurred vision as well as discomfort. A range of factors can contribute to dry eyes, including heat, age, medications and medical conditions. Lengthy use of screens and contact lenses can also contribute.

 

Intense sunlight and high temperatures can exacerbate evaporation, leaving eyes without the lubrication they need. This can be a particular problem if you spend an extended period outdoors in the heat. Air-conditioned indoor spaces can also be challenging due to their low humidity levels, contributing to dry eyes.

 

Managing Dry Eyes During a Spanish Summer

What can you do to manage the discomfort caused by dry eyes during the hot weather?

 

  • Keep Hydrated

Ensure you remain hydrated by drinking sufficient amounts of water. During hot weather, this is likely to be more than usual. Proper hydration is essential for maintaining tear production.

 

  • Use Eye Drops

Over-the-counter lubricant eye drops can provide relief from the discomfort of dry eyes by helping to lubricate the eye. Always follow the instructions provided on the packaging.

 

  • Remember to Blink

Intentional blinking helps to spread tears evenly across the surface of your eyes. This is particularly important if you’re spending long periods of time focusing on screens, or you’re spending extended periods in air-conditioned environments.

 

  • Protect Your Eyes

Wearing sunglasses that block both UVA and UVB rays will shield your eyes from harmful sunlight while helping to reduce the rate of tear evaporation. Wrap-around styles can also provide additional protection from wind and dust.

 

  • Manage Screen Time

Extended periods of screen time can reduce blink frequency, contributing to dry eyes. Follow the 20-20-20 rule: Every 20 minutes, look at an object 20 feet away for at least 20 seconds.

 

  • Raise Humidity Levels

Higher humidity helps to counteract the impact of heat on your eyes. If you have air conditioning, consider using a humidifier to help maintain a comfortable level of indoor humidity. This can help prevent rapid evaporation of tears.

 

  • Nutrition

There is evidence that a diet rich in omega-3 fatty acids can help promote healthy tear production. These are found in foods such as oily fish, walnuts and flaxseed. They also have a range of other health benefits making omega-3 a popular supplement.

 

  • Stay Indoors

During very hot periods it’s sensible for a range of health reasons, not least avoiding dry eyes, to remain indoors. This is particularly important during the hottest time of the day. This is usually between 10 am and 4 pm.

 

  • Review Your Medication

In some instances, certain medications may be exacerbating dry eye problems. If you are taking medication, consult your doctor or pharmacist to ask about possible side-effects such as dry eye. If necessary, it may be possible to change medications for one that is less likely to cause a problem with your eyes.

 

  • Consult an Ophthalmologist

If you are experiencing persistent, severe and painful dry eye symptoms, then it’s important to consult an ophthalmologist. They can recommend appropriate treatments, including prescription eye drops or other therapies. They can also check your overall eye health.

Eye drops are practical, simple-to-use medical treatment for a range of eye conditions, as well as alleviating symptoms such as itchiness, burning, and discomfort in the eye. Eye drops are prescribed by an ophthalmologist to prevent eye infections or to aid recovery from surgery.

Prescribed eye drops should be used as directed. This is important because eye drops are formulated in a particular way for maximum safety and effectiveness. If they’re used improperly, at best they will be ineffective, at worse they could lead to adverse effects.

In this article, Gurjeet Jutley looks at some of the ‘Do’s and Don’ts’ to keep in mind when using eye drops.

 

The Do’s of Using Eye Drops 

When using eye drops, there are certain things you should do to ensure that they work effectively and to minimise the risk of complications. These include:

  • Store In A Cool Dry Place

It’s important to store eyedrops in a cool, dry place out of direct sunlight. Exposure to sunlight can degrade the quality of the medication over time.

  • Check Your Drops Before Use

Contaminated eye drops can introduce harmful bacteria or other pathogens into the eyes, potentially leading to infections or other complications. Do not use eye drops that have expired or appear cloudy, discoloured, or contain particles.

  • Wash Your Hands Thoroughly

Firstly, always wash your hands thoroughly before administering the drops. This helps to prevent introducing harmful bacteria to your eyes, which could cause infections.

  • Follow The Instructions

Always follow the instructions provided by the ophthalmologist or as stated on the packaging carefully. This includes the correct dosage, the frequency of administration, and the duration of use. Overusing eye drops could lead to unwanted side effects or even damage to the eye. Always check the expiration date on the packaging.

  • Wait Between Using Different Drops

If you’re using more than one type of eye drop, ensure that you wait for at least five minutes between administering each drop. This prevents the first drop from being washed away before it has had a chance to work.

 

The Don’ts Of Using Eye Drops

There are some important things to remember not to do when using eye drops. These include: 

  • Don’t Share Eye Drops

It’s important that you only use eye drops that have been prescribed to you. Eye drops are medication and sharing them can lead to allergic reactions or the spreading of infections.

  • Don’t Touch The Dropper Tip

The dropper tip of the eye drop bottle should never come into contact with your fingers or any other surface, as this can introduce harmful bacteria into the bottle and potentially cause an infection.

  • Don’t Use Expired Eye Drops

Expired eye drops can lose their effectiveness or even become contaminated, so it’s important to check the expiration date and dispose of any old drops.

  • Don’t Rub Your Eyes After Using Eye Drops

Rubbing your eyes after applying eye drops can cause the medication to be rubbed away or even spread to other parts of your face, such as your nose or mouth. It’s best to wait a few minutes before touching your eyes or using any other products around your eyes.

  • Don’t use multiple types of eye drops simultaneously

Different types of eye drops can interact with each other, leading to side effects or decreased effectiveness. If you have been prescribed multiple types of eye drops, make sure you understand how and when to use each one and in what order.

 

Effective treatment for a range of conditions

Eye drops are an effective, simple and easy to use medication for a wide range of eye conditions including dry eyes, glaucoma, allergies and infections. They are easy to use and can provide quick relief without the need for more invasive treatments.

However, it is important to use eye drops as directed and to follow the do’s and don’ts of eye drop use to ensure that they are effective and safe. If you have any questions or concerns about using eye drops, it is always best to consult with a healthcare professional or eye care specialist.

Lens replacement surgery, also known as lens exchange or lens replacement, is a surgical procedure in which the natural lens inside the eye is removed and replaced with an artificial lens. It can be a very valid option instead of wearing contact lenses or glasses.

In this blog, Gurjeet Jutley provides a quick guide to lens replacement surgery and outlines what you can expect.

 

Is lens replacement surgery the same as cataract surgery?

Lens replacement surgery is sometimes confused with cataract surgery, and while there are similarities there are also differences. Cataract surgery involves removing a cloudy lens to improve vision. In lens replacement surgery, the lens is fairly clear and the object of removal is to improve the refraction, i.e. the ability to see without using glasses.

 

What artificial lenses are available?

There are a number of different types of artificial lenses that can be used depending on the particular needs of the patient. Multifocal lenses can help you see clearly at all distances. If someone also has astigmatism as well, toric multifocal lenses can be used to correct it.

Recently, extended depth of focus implants (EDOF) has been introduced. These feature a different design from traditional multifocal lenses and can provide an enhanced depth of focus. They can also reduce a range of visual disturbances, such as starbursts, halos and glare, all of which may occur when traditional multifocal lenses are used.

The key thing is the right choice for each individual patient, i.e. an informed decision.

 

What does the procedure involve?

The procedure for lens replacement surgery is performed in a similar way to cataract surgery.  The patient is awake during the surgery and can be given a sedative to help them relax if required.

The procedure will usually only take around 15-30 minutes and the patient is able to return home on the same day as their surgery. Each eye is operated on separately usually with a gap of one or two weeks between each procedure. It’s easier for the brain to adjust to the new information it is receiving if the second eye is operated on as soon as the first eye has recovered.

 

Recovering from lens replacement surgery

After the surgery is completed your eye will be covered with a protective pad and shield that you will need to keep in place for the first 24 hours. This will limit your vision, so you will need someone to escort you home safely. You will then need to wear it at night for the following week. This is to limit the risk of your eye being rubbed while you’re sleeping which can damage the site where the cut was made.

Blurred vision for a few days after surgery is common but should gradually clear up. Vision will eventually stabilise between two to four weeks. Eye drops will usually be required for about four weeks. These reduce the risk of an infection occurring and can aid the healing process.

It’s important to avoid vigorous exercise and swimming for at least two weeks following surgery. The use of computers and other screens should also be limited or avoided. It’s possible to begin driving as soon as you are able to meet the DVLA requirement to read a licence plate number from 20 metres away.

Astigmatism is a common visual finding that most commonly affects the shape of the cornea and can cause distorted or blurry vision. It is essential to properly diagnose and treat astigmatism to maintain good vision and eye health.

 

In this article, Gurjeet Jutley discussed the causes, symptoms, and treatment options for astigmatism.

 

What is astigmatism and how is it caused?

 

The eye has two structures, the cornea and the lens, that have curved surfaces. These bend, or refract, light onto the retina to make images. The cornea is the clear front surface of the eye alongside the tear film, and the lens is a clear structure inside the eye that changes shape to help the eye focus on near objects.

 

When an eye is perfectly spherical in shape each of these elements will have a round curvature. This allows the cornea or lens to refract all incoming light equally to create a sharply focused image directly on the retina at the back of the eye.

 

Astigmatism is caused when there is an irregularity in the shape of the cornea, the clear front surface of the eye, or the curvature of the lens inside the eye. This irregular curvature causes multiple focus points, causing blurred vision.

 

One can have either corneal astigmatism, lenticular astigmatism or both. Hence astigmatism can occur in combination with other vision conditions such as nearsightedness (myopia) or farsightedness (hyperopia), cataract, etc.

 

 

What are the common symptoms of astigmatism?

 

Some of the common symptoms of uncorrected astigmatism are:

 

  • Distorted or blurred vision
  • Discomfort or eyestrain
  • Headaches

 

A refraction can help identify and correct astigmatism by implementing treatment. Hence the importance of regular eye tests, encompassing:

 

  • Visual acuity test

 

This measures how clearly you can make out letters or symbols from a distance.

 

  • Retinoscopy

 

This involves shining a light into the eye to measure the reflection.

 

  • Keratometry

 

This is a test that’s used to measure the curvature of the cornea to determine the presence and degree of astigmatism.

 

  • Corneal topography

 

This creates a detailed map of the front surface of the eye and can help to identify corneal abnormalities including astigmatism.

 

 

How is astigmatism treated?

 

Astigmatism is treated either by wearing corrective lenses or through refractive surgery.

 

  • Corrective lenses

 

Corrective lenses in the form of glasses or contact lenses help to compensate for the uneven shape of the eye. Lenses corrects the light to bend into one focal point.

 

  • Refractive surgery

 

Refractive surgery can improve correct astigmatism, improve vision overall and reduce the need for eyeglasses or contact lenses. The surgery can be at the level of the cornea or lens, such as toric lenses.

 

 

If you are having difficulties with your vision or have any of the possible symptoms of astigmatism outlined above it’s important to seek an examination as soon as possible. For further advice regarding astigmatism or to book a consultation contact Gurjeet Jutley today.

Although each case is different, your vision should begin to get back to normal within a few days of having the procedure.

 

Whilst cataract surgery is common, a reasonable period of recovery time is still needed, and when you get home you will want to rest and recuperate for a while.

 

In this article, Gurjeet Jutley explains what you can expect after cataract surgery, and how long it will take until you can get back to your normal activities.

 

Going Home

 In most cases, you should be able to go home on the same day as your surgery. You will usually have a pad and plastic shield across your treated eye, and this can normally be removed the day after surgery. Feeling should begin to return to your eye within a few hours of the procedure, but it may take several days for your vision to return to normal.

 

Initially, you may experience a number of different side effects including grittiness, watering, blurred vision, and a red or bloodshot eye. These should begin to ease within a few days, but in some cases, some side effects may linger for a few weeks. If you have any concerns, always seek help.

 

Driving

As cataract surgery involves anaesthesia you will not be able to drive yourself home after the procedure. It’s therefore important to ensure that you have alternative travel arrangements in place. You will be able to drive again within days of surgery providing you don’t experience any blurriness or other side effects that restrict your vision.

 

It can be prudent to err on the side of caution and wait a little longer if possible before resuming activities such as driving to give your eye more time to heal.

 

Daily Activities

Ordinary daily activities can be carried out the same or the following day after your procedure as long as due caution is exercised. This can include activities such as preparing food and domestic tasks.

 

Returning to work

Normally, you should be able to return to work within a few days of your surgery. However, if your work involves heavy lifting, takes place in a dusty environment or is physically demanding, then you should remain off work for a longer period to allow for a full recovery.

 

Avoid Strenuous Activity

 Recovery for most people is straightforward, but it’s important to avoid any strenuous activities in the days immediately following your surgery. What counts as strenuous will differ from person to person but after a week of recovery following your surgery you may be able to restart light aerobic exercises.  This might include walking or jogging on a treadmill, but you should avoid any high-intensity activities. You shouldn’t carry out any exercises which involve putting your head below your waist, as bending down places strain and pressure on your eyes.

 

Any intense exercise will cause the pressure in your eye to rise so keeping this pressure at a low level will assist with faster healing. When your eye is recovering it’s very important that it remains sterilised and clean in order to help it heal without an adverse reaction.

 

Avoid swimming for at least two weeks

It’s recommended that you do not swim underwater for at least two weeks post-surgery to reduce the risk of developing an infection. Water can carry a range of bacteria that may be harmful to your eyes as they heal.

 

It’s also important to remember this when showering, taking a bath or washing your hair immediately after your surgery. It’s always recommended that you try to wash your hair with your head tilted backwards to reduce the risk of shampoo getting in your eyes.

What happens after glaucoma surgery?

Unlike cataract surgery, glaucoma surgery very rarely improves vision. Rather, it’s intended to stabilise vision and reduce the risk of future sight loss by reducing the pressure within the eye. This can be done in many different ways: essentially either reducing fluid into the eye or increasing fluid leaving the eye.

 

In this brief article, Gurjeet Jutley takes a look at what you can expect after your surgery has been completed

 

What to expect after your glaucoma surgery

The length of time it can take for you to recover will depend a great deal on the type of surgery that you have and your overall health.

Quicker recovery periods may last as little as around 3 weeks, but a slower recovery could take months.

 

Your sight

 The vision may become blurred and this can last for a few days or in some cases, a few weeks. It’s important to monitor this as you should see a steady improvement until you reach the point that your sight is stabilised.

 

If you experience any sudden loss of eyesight during this period it’s important that you report this immediately as it can be a sign of an infection or a bleed. Whilst rare, it is grave and needs management rapidly.

 

Physical symptoms

Any surgical procedure may leave you with some mild pain and discomfort immediately afterwards. Over-the-counter pain medications may be required and it should ease up within a few days. Any extreme pain should be reported immediately.

 

You may also experience a degree of irritation and discomfort in the eye for a few days, as well as itching. You may find that your eyes water or tear up more than normal during the recovery period. This will be most noticeable during the early stages of your recovery, easing off over time. It’s also common for swelling and redness to develop around your eyes for a few days following the procedure.

 

Getting back to normal

Post procedure, it’s important to pace yourself and to remember that you will need some time to recover. This means taking more time to relax and recuperate.

 

Avoid any vigorous exercise and slowly reintroduce physical activity over a number of days. Going for a short gentle walk is more advisable than a workout in the gym.

 

You may also want to take some time off from activities that place a strain on your eyes such as reading and writing. Your vision may be blurry for a few days making tasks like these more difficult

 

Driving should be avoided for a week or so, but this will depend on how quickly your vision returns to normal and the underlying health of the eye. It may be helpful to stock up on groceries and other household essentials before surgery. Although it’s possible to return to work within days of glaucoma surgery, it’s usually sensible to take a week or longer off work to recover fully.

 

Taking care of your eyes

 

You shouldn’t touch or rub your eyes if you feel any discomfort after surgery. Doing so can result in your eye taking longer to heal and in some cases may even cause damage. Make sure you wash your hands with soap and warm water before using eye drops.

 

It’s important to take particular care of your eyes during summertime and to wear sunglasses to protect your eyes from the sun’s rays hat irritate sensitive eyes.

 

While recovering you should also refrain from swimming pools and hot tubs, which can carry bacteria that could enter your eye and cause infection.

What does seeing halos around lights mean?

If you notice that you are seeing bright circles or rings, like halos, around light sources when you look at them, it requires urgent assessment. It has several potential causes and consequences, some of which have serious implications.

 

The phenomena can be a particular problem when it happens at night, or in a dimly lit space where they can interfere with your vision. It might just be a normal response to bright lights, such as overly bright headlights on an oncoming car, or they might have an underlying cause that requires further investigation.

 

In this article, Gurjeet Jutley looks at the topic of seeing halos and how and when you should seek help.

 

How do you know if halos are caused by a serious condition?

 

If halos appear suddenly, or if you sometimes or always see rainbow patterned halos, have blurred vision, pain or feel any other discomfort, they might indicate a serious condition.

 

If you have never experienced halos previously, or their frequency or regularity has suddenly increased, then please seek medical attention. The correct treatment plan can then be implemented.

 

 

What are the causes of seeing halos around lights?

 

Halos appearing when you look at light sources are usually caused by diffraction. This is the bending of light as it enters your eye and there are a number of different eye conditions that might cause this to happen. These include:

 

  • Dry eye syndrome

 

When your eyes are chronically dry this is known as dry eye syndrome (DES). It can alter the shape of the cornea, causing halos to appear from the scattering of light when it enters the eye.

 

  • Cataracts

 

Seeing halos around lights can be seen with cataract. A cataract develops when the transparent lens of the eye gradually becomes cloudy or opaque. As the lens becomes cloudy light will be bent in an unusual way. The scattering of light can cause the appearance of halos.

 

Halos are also sometimes a side-effect of surgery, where a cloudy lens has been replaced with a plastic intraocular lens and its effects should decrease over time.

 

  • Astigmatism

 

When a cornea is irregularly shaped this is known as astigmatism. This irregularity can bend any light that enters the eye in unexpected ways, distorting vision and causing the appearance of halos.

 

  • Corneal dystrophies, such as Fuch’s

 

Fuch’s dystrophy is a progressive genetic eye disorder that can cause the cornea to swell. When this happens, the shape of the cornea is altered and light is no longer able to enter the eye at the correct angle leading to the appearance of halos around lights. Symptoms of the disorder will usually begin to appear between the ages of 50 and 60.

 

  • Glaucoma

 

Glaucoma is an eye condition caused when the optic nerve becomes damaged, usually in the context of elevated pressure within the eye. It is a common condition and one that is the leading cause of blindness worldwide.

 

Seeing halos around light can be an early sign of acute-angle glaucoma and this should be treated as a medical emergency.

 

  • LASIK surgery

 

Laser in-situ keratomileusis or LASIK surgery can cause temporary halos immediately after surgery.

 

 If you notice halos appearing when you look at lights it can be a cause for concern. Seek professional advice by contacting Gurjeet Jutley as soon as possible to allow for further investigation and treatment if necessary.
