What is LASIK?
Laser Assisted In-situ Keratomileusis or LASIK, is an outpatient procedure used to treat myopia (near sight), hyperopia (far sight) and astigmatism. In LASIK, your ophthalmic specialist uses a microsurgical instrument and a specialized Excimer laser beam is used to reshape the cornea. Reshaping your cornea alters the focusing power of the eye, allowing you to become less dependent on glasses or contact lenses. In most people, LASIK allows you to do without them entirely.
Why should you consider LASIK?
For many years, the only way people could correct their vision was to wear spectacles. Over the last forty years, contact lenses have become increasingly popular as their design and availability has improved.
More recently, LASIK has been a major breakthrough among vision correction techniques. With its outstanding results, LASIK has rapidly gained acceptance as a realistic alternative and enabled millions of people worldwide to enjoy a new found freedom living their lives without the inconvenience of glasses or contact lenses.
How does LASIK work?
The Cornea provides two thirds of the eye's focusing power. Altering its shape changes the power of the eye. LASIK flattens the cornea to correct myopia (near sight) and steepens the cornea for hyperopia (far sight). The reshaping process can also be used to correct astigmatism at the same time.
The specialist creates an ultra thin corneal flap, using a highly specialized instrument called a microkeratome. The Excimer Laser is then used to reshape the cornea under the flap. The flap is replaced and adheres firmly and fully without the need for stitches. With the flap in place, the eye recovers quickly and vision is rapidly restored with minimal discomfort.Our technology:

Who is suitable for LASIK?
You may consider this procedure if you:
- Are over 20 years old and have had a stable prescription for at least 1 year
- Have healthy eyes with no diseases (e.g. cataract, glaucoma)
- Are in good general health
- Are not pregnant nor planning pregnancy in the immediate future
What happens after LASIK?
- Vision: Visual recovery is rapid after this procedure and most people will see well within a day or two.
- Pain: The procedure and recovery is painless
- Time off: You will be able to come in for treatment over the weekend and return to work without taking time off from work.
- Restrictions: There are very few restrictions during recovery. Antibiotic and anti-inflammatory drops have to be instilled for about a week after surgery.
- Enhancement: Most people attain the clear vision they hoped for after one treatment. In the rare event of regression or if the desired correction is not achieved by your first procedure, then your consultant may recommend an enhancement, which is an easier procedure.
Risks, complications and side effects
Like any procedure on the body, LASIK has risks and complications that should be carefully considered. Sight threatening risks are extremely rare and should not be a cause for concern. Most complications are minor and can be treated without any loss of vision. Some people experience temporary side effects after LASIK that disappear in time.
If you have been waiting for a safe alternative to set you free from your spectacles and contact lenses, then LASIK may be your answer.
Other Refractive Procedures
LASEK / EPILASIK: This procedure also incorporates excimer laser to change the focusing power of the cornea. This procedure is recommended for cases with thinner corneas.
ICL (Implantable Collamer Lens) Implants: Introduction of a thin collamer lens inside the eye. This is indicated in patients with very high refractive errors with excellent results.
Myth Busters (Click on myth to know the fact)
Fact: Most patients, who have undergone LASIK, see immediate vision improvement after surgery. In most of the cases the patient can return to work after 3 days of the procedure.
Fact: LASIK treats astigmatism extremely well. In fact, those who have LASIK to correct astigmatism often have a better quality of vision after surgery than before with glasses or contacts.
Fact: LASIK is an investment that can actually save you money. When you factor in what you're already spending on glasses, contacts and solution every year, LASIK is an affordable solution.
Fact: LASIK is widely regarded as one of the safest elective procedure in modern medicine. It also yields some of the highest levels of patient satisfaction of any procedure.
Fact: Think of some of the moments you've missed when you didn't have your corrective lenses on. LASIK can give you clear vision - all the time. Glasses and contacts also don't do a very good job of correcting astigmatism, so those who have LASIK to correct astigmatism often have a better quality of vision after surgery than before with corrective lenses.
Fact: No patient has ever gone blind from a LASIK procedure.
