The risks and benefits of lasik that you should know


According to the Mayo Clinic, about 85 percent of people who’ve undergone refractive surgery no longer need to depend on their glasses or contact lenses most of the time. People with a low grade of nearsightedness tend to have the most success, and people with a high degree of farsightedness along with astigmatism have the least predictable results.

Most people who undergo laser eye surgery
no longer need glasses or contacts.

The results you get, of course, will depend on the nature and degree of your vision problems going into surgery and the quality of the work your doctor does.

Risks and Complications

We’re all well-acquainted with the touted benefits of corrective surgery, but what about what the ads don’t necessarily tell you? What are the risks associated with laser eye surgery? Any surgical procedure carries with it a certain amount of risk, and laser eye surgery is no different.

Some of the risks of undergoing such procedures include:

  • Loss of vision. If things don’t go as planned, some patients emerge from the procedure with vision that’s worse than what they came in with.
  • Development of new visual problems. Some patients develop a glare, halos, starbursts and double vision as a result of laser eye surgical procedures.
  • Undertreatment/ Overtreatment- Reshaping the cornea is a delicate business. Sometimes the cornea is not reshaped enough—too little material is taken out; sometimes it’s reshaped too much—too much material is taken out.
  • Dry eyes. Many patients report having dry eyes after surgery. Although eye drops (plus a little time for healing) are usually able to correct or at least help the problem, in some more serious cases, special plugs are required to prevent tears from draining away from the eyes.
  • Infection and other flap-healing problems. Cutting a  flap into your cornea is like cutting any other part of your  body. There is always the potential that it may get infected or otherwise not heal properly.
  • Results may diminish with Time. Although technically not a “risk” of surgery, you should know that even with the best laser eye surgery, the results don’t last forever. The cornea continues to age and change shape. Keep in mind that these procedures are still so new that no long-term data exists. In how many people will Lasik corrections last twenty years or longer? We don’t really know. The first FDA-approved Lasik eye surgery was in 1998.

Talk with your doctor about which risks he thinks might affect you and whether or not he believes laser eye surgery is still right for you.

Rabun Jauh Pada Kanak-Kanak Perlu Dirawat

Rabun jauh atau myopia adalah masalah di mana seseorang itu tidak dapat melihat objek yang berada jauh dengan jelas. Apa yang menyebabkan seseorang itu rabun adalah bola mata yang lebih panjang daripada biasa menyebabkan imej tidak terfokus dengan baik. Seseorang itu akan memerlukan cermin mata atau kanta lekap untuk membantu memperbaiki imej yang terbentuk.

Dijangkakan lebih kurang 1 billion orang di seluruh dunia mempunyai rabun jauh, dan ini semestinya memberi impak kepada kos penjagaan kesihatan dunia. Sebuah kajian pada tahun 2003 yang dijalankan di Gombak, Selangor, mendapati 35% daripada kanak-kanak bersekolah adalah rabun, yang mana 65% adalah berbangsa Cina, 30 % Melayu dan 15% India.

Antara faktor peningkatan rabun di kalangan kanak-kanak adalah kerana terlalu banyak melakukan kerja yang memerlukan fokus pada jarak dekat, seperti membaca, menonton television dan bermain iPad atau peralatan elektronik, dan seterusnya kurangnya bermain di luar rumah.

Semasa kanak-kanak masih membesar, kanta mata berfungsi menentukan berapa besar bola mata perlu membesar. Kanak-kanak yang contohnya selalu bermain peranti elektronik, dan kurang bermain di luar, kanta matanya akan sentiasa dalam keadaan bulat (globular), dan ini memberi signal kepada mata untuk membesar. Apabila bola mata menjadi terlalu panjang, maka mereka akan membesar sebagai dewasa yang rabun. Apabila kuasa cermin mata terlalu tinggi iaitu melebih 6 diopter atau -6.00DS, mereka mengalami risiko untuk saraf retina tertanggal, lubang pada saraf retina, glaukoma dan pelbagai masalah serius yang lain.

Lebih ramai kanak-kanak mengalami rabun jauh berbanding rabun dekat, tetapi hanya melalui pemeriksaan lengkap, jenis-jenis rabun itu dapat ditentukan. Sekiranya ibu bapa mendapati anak mereka juling, selalu mengadu sakit kepala atau tidak nampak di sekolah, atau mereka mempunyai postur kepala yang tidak normal semasa menonton TV (contohnya teleng ke kiri atau ke kanan), ibu bapa perlu membawa anak itu untuk pemeriksaan dengan pakar mata secepat mungkin, sebaik-baiknya sebelum usia 6 tahun.

Jika dikesan dari awal masalah rabun yang dihadapi kanak-kanak itu dapat dirawat dengan menggunakan cermin mata. Walau bagaimanapun, sebaiknya pembentukan rabun ini dicegah dari awal kerana mencegah itu adalah lebih baik daripada merawat.

Antara rawatan yang disyorkan adalah dengan pemakaian cermin mata. Penggunaan kanta lekap adalah tidak digalakkan bagi kanak-kanak kerana mereka kurang cermat dari segi penjagaan kanta lekap, contohnya sekiranya kanak-kanak itu tertidur dengan memakai kanta lekap, ini boleh menyebabkan jangkitan kuman. Pembedahan LASIK untuk merawat rabun jauh, hanya boleh dilakukan selepas seseorang itu mencapai usia 21 tahun, kerana selepas usia itu mereka tidak lagi membesar.

Bagi ibu bapa yang mempunyai anak-anak yang rabun, sebaiknya pemeriksaan mata dilakukan setahun sekali, tetapi bagi kanak-kanak yang sedang membesar dengan pantas, contohnya mereka yang baru aqil baligh, sekiranya mereka mengadu cermin mata mereka semakin kabur atau kerap sakit kepala, bawalah mereka untuk pemeriksaan lebih awal.

A moment with Si Pei, one-half of WIT X FOLLY


Also known as @ohhdivine on Instagram, Si Pei walked into Atlas Eye Specialist Centre sometime in July and had her refractive surgery assessment done. The assessment also includes a consultation with Dr David Chan, Senior Eye Surgeon of Atlas Eye. 

She shares with us some queries she has about Refractive Surgery and we’ve helped to answer them. Read on to find out if they are the questions in your mind too!

What’s the difference between LASIK and ReLEx® SMILE?

The biggest difference between the 2 procedures is that LASIK has a flap of 22mm created while ReLEx® SMILE is done with a 2 to 4mm keyhole incision. With the small incision, there’s no flap, lesser chance of dry eyes and your cornea retains its structural strength.

Both procedures are comfortable and have a relatively fast recovery time of 3 days, compared to the older generation – Surface Ablation (PRK/ Lasek / Epi-Lasik) – which takes at least one week.

Will I still need to wear glasses when I get presbyopia (老花眼) in future?

Unfortunately, presbyopia is age-related and no one can escape from it, even if you’ve had laser refractive surgery done. There are, however, some laser techniques that reduces the impact of presbyopia.

Does everyone get dry eye after surgery?

Dry eye is the most common side effect of laser refractive surgery, often associated with LASIK, and lubricating eye drops will be prescribed to soothe the discomfort, which would eventually subside in most cases.

I’ve heard that there are people who return to wearing glasses a few years after surgery. Does it happen often?

The laser treatment gives very accurate results. However, in some cases where the patients’ eyes heal too well, some refractive errors may remain. Those residual errors that are significant may be corrected via an enhancement laser treatment.

At Atlas Eye, should the surgeon and you agree that there are enough benefits for an enhancement procedure within 24 months of the first laser treatment, an all-inclusive enhancement surgery will be performed at no additional cost to the patient.

Can I wear cosmetic contact lens after surgery?

It’s a common misconception that contact lenses cannot be worn after refractive surgery. You can actually have them on after the surgery, but hold back for at least a month to prevent infection while the eye is healing. Moreover, if you have dry eye after surgery, having contact lens on tend to make it worse.

When can I put on makeup after surgery?

It’s best to avoid all makeup for at least a week. However, if you really need to, you can apply light makeup, such as foundation and blusher, 3 days after surgery. Avoid any eye makeup for at least a week as the small particles contained in the makeup could come into contact with your eye, increasing your risk for irritation and infection.

6 Tips for Eye Health and Maintaining Good Eyesight

  1. Make your working environment comfortable.


Observe proper posture when working and keep your computer monitor below eye level and at least 20 to 26 inches away from your eyes. Another way to prevent eye fatigue is to wear proper graded glasses.


  1. Wear sunglasses.


Not only are sunglasses cool, the coolness can actually prevent the sun’s UV rays from damaging your eyes. Extended exposure to UV rays has been linked to eye damage, including early onset of cataracts and macular degeneration.


  1. Use proper lighting when working.


Proper lighting is essential to make everything less straining for your eyes. Low intensity bulbs and fluorescent lights are ideal to use as lighting condition for your work area. In addition, adjust your computer’s brightness, text size and contrast that properly suit your vision and make you feel comfortable.


  1. Take a break and exercise.


Doctors’ advice is to look up and away from the computer for at least 15 minutes every couple of hours to relax the muscles inside the eyes. Especially if you need to do a lot of near work during the day.


  1. Annual Eye Check.


It is always good to have your eyes check at least once a year to make sure your eye health is optimum. You will also find out any onset of eye diseases earlier.


  1. Enjoy outdoor activities.


Let your eyes enjoy while you participate in outdoor activities like walking in greenery or cycling by the beach. Not only is it good for your health, but it can also help the eyes relax more by looking at far distances for a change.

7 Good Foods That Boost Your Eye Health

Are you eating the foods that are best for your eyes?

Carrots may be the best known food for helping your eyes but there’s more. A diet that is rich in antioxidants, vitamins and minerals not only improves your eye health, it can even help to prevent eye diseases.

Lutein, Vitamin A, C & E and Omega-3 fatty acids all play a role in eye health. Here are some powerhouse foods for healthy eyes to try.


Leafy greens


Kale, spinach and broccoli, just to name a few, are full of lutein and zeaxanthin, that can help stem the development of macular degeneration and cataract.Avocado is also a good source of antioxidant, that can protect the eyes from harmful UV rays.



Omega-3 fatty acids help your eyes fight inflammation, protect against dry eye and also prevent macular degeneration and cataracts. Salmon and sardines have the most omega-3s, but tuna is also a good source. Aim for at least two servings a week. Otherwise, you can also take fish oil supplements or vegetarian supplements like flax seed oil.


The vitamins and nutrients in eggs, including Lutein and Vitamin A, promote eye health and function. Additionally, Vitamin A protects against night blindness and dry eye.

Whole Grains


Foods with low glycemic index (GI), such as quinoa, brown rice and whole-wheat breads, not only promote overall eye health, but also help reduce risk of macular degeneration.

Colourful Fruits (and vegetables)


Not only do they make your food more appetizing, fruits like grapefruits, oranges, and strawberries are high in Vitamin A, which reduces the risk of cataract and macular degeneration. Corn, pumpkins and peppers are also excellent sources of Vitamins A and C.

Nuts and Legumes


Almonds, walnuts, pistachios – whichever you prefer – are rich in Omega-3 fatty acids, zinc and Vitamin E. Kidney beans, black-eyed peas and lentils are also good sources of bioflavonoids and zinc, which help protect the retina and lower the risk of macular degeneration and cataract.

Sunflower Seeds


Keep your eyes healthy and disease-free by snacking on sunflower seeds. They are an excellent source of Vitamin E and zinc, which helps your body absorb Vitamin A.

What exactly is lazy eye?

Amblyopia, also known as lazy eye, is when there is a vision development disorder, in which an eye fails to achieve normal visual acuity even with prescription glasses or contact lenses. It usually occurs in one eye but in some cases, it can manifest in both eyes.

Ideally, Amblyopia should be detected early in life and promptly treated so reduced vision can be avoided. It does not go away on its own and iIf left untreated, can lead to vision impairment, included blindness.


What causes lazy eye?

  • The most commonly known cause for Amblyopia is Strabimus, where one eye looks at the object you’re viewing and the other is misaligned, either inward (Esotropia), outward (Exotropia), upward (Hypertropia) or downward (Hypotropia).


  • Due to a lack of stimulus, children who have congenital cataract in their early years.
  • Children who have a large difference in refractive error between both eyes.
  • Family history of Amblyopia.

Children with Amblyopia would not usually complain of poor vision, because they wouldn’t really know, until it is picked up at an eye check-up or screenings in school. Hence, it is important for parents to bring the child for routine eye check-up.


How do you tell if your child has Lazy Eye?

Besides noticing if your child has crossed eyes or some other apparent eye misalignment, another clue is if he or she fusses when you cover one eye.

You can try this simple screening test at home by simply covering your child’s eyes (one at a time) when he or she is performing a visual task, such as watching TV.

If your child is not bothered when one eye is covered, try the other eye. If your child tilts his or her head or pushes your hand away when you cover the other, this may suggest that the first eye you covered is the “good” eye and the other is “lazy” or amblyopic, causing blurred vision.


How to treat Lazy Eye?

In some cases of children having refractive error, normal vision can be achieved simply by wearing prescription glasses. Usually, however, the child would also need to undergo patching (occlusion therapy) to force the brain to pay attention to the visual input from the amblyopic eye, enabling normal vision development for that eye.


In some children, atropine eye drops have been used to treat amblyopia. It helps by blurring vision in the good eye to force your child to use the weaker eye more, to strengthen it. One advantage of using atropine eye drops is that it doesn’t require your constant vigilance to make sure your child wears the eye patch.

It is important to detect amblyopia and treat it early. If it is detected after the age of 8, it might not be possible to reverse the damage, leading to perpetual poor vision and a loss of depth perception.

For Strabismic Amblyopia, strabismus surgery is needed to straighten the eyes, followed by patching and often, some sort of vision therapy to help both eyes work together as a team.

What Is Laser Eye Surgery?


Laser Eye Surgery can be also known as Vision Correction Surgery or Refractive Surgery. It is a procedure that helps to correct Near-sightedness (Myopia), Far-sightedness (Hyperopia) or Astigmatism.

Currently in Singapore, there is Surface Ablation (PRK, LASEK and Epi-LASIK), LASIK and ReLEx® SMILE for laser correction. For some patients who cannot do laser vision correction, they can also choose from Implantable Contact Lenses (ICL) or Refractive Lens Exchange (RLE).

The Different Types of Refractive Surgery

Refractive surgery aims to reduce a person’s reliance on spectacles and contact lenses. Not only does it bring convenience, there is less hassle and concern about contact lens related infections. The 3 main types of refractive surgery are:

  • Laser Vision Correction Surgery
  • Implantable Collamer Lens
  • Refractive Lens Exchange

Laser Vision Correction Surgery has 3 generations.


1st Generation: Surface Ablation (PRK/ LASIK/ EPI-LASIK)


Surface ablation is ideal for people who do contact sports or have thin corneas. However, due to the removal of epithelium during surgery, there is more discomfort as compared to the other types of refractive surgery. There is also a longer commitment to medication and downtime from work.



2nd Generation: LASIK


LASIK is widely popular and it is one of the most common refractive procedures done. In LASIK, a large flap is created for the laser treatment. Due to the flap creation, there is a higher risk of dry eyes and potential cornea weakening. Recovery time for LASIK is very short as compared to surface ablation – only 3 days. There is also a shorter commitment to medication. This method is not advised for patients who do contact sports, as they run the risk of flap dislodgement should there be any direct trauma or impact to the eye.



3rd Generation: ReLEx® SMILE


ReLEx®SMILE is done through a small keyhole incision on the cornea. It combines both the advantages of PRK and LASIK such as fast recovery and lesser dry eyes as it’s a small incision. Downtime from work and commitment to medication post-surgery is comparable to LASIK. SMILE is ideal if you want a fast and comfortable recovery with no creation of flap.

Corneal Collagen Cross-Linking (CXL)


During refractive surgery, the cornea shape and integrity is changed. This puts the cornea at a greater risk of weakening, also known as corneal ectasia. With collagen cross-linking, vitamin B and UV is being instilled. The corneal integrity is strengthened as more links are formed. In patients with slightly thinner corneas who undergo refractive surgery, CXL aid in improving the refractive stability of the eye.



Implantable Collamer Lens (ICL)


Implantable Collamer lenses are lenses that are implanted into the eye, behind the iris and in front of our natural lens, to treat high degrees of myopia. They are also able to provide superior clarity of vision. The results of the implants are reversible, and should a patient develop cataracts as they age, the implants can be removed. One major downside of ICL surgery is that it is 2 times more costly as compared to LASIK and SMILE.



Refractive Lens Exchange (RLE)


Refractive lens exchange replaces the eye’s natural lens with an intraocular lens (IOL). The lens implant is calculated to correct the eyes’ refractive errors. This surgery is suitable for patients who have early cataracts or are middle-aged. This way, they do not have to worry about having to go through cataract surgery in future as the natural lens are already replaced in this procedure.
