LASIK, or laser in situ keratomileusis, is an outpatient surgical procedure used to treat:
Your Singapore LASIK Surgeon will use a special laser to reshape the cornea to improve the way light rays focus on the retina (the light-sensitive “film” at the back of the eye).
LASIK is performed to decrease your reliance on glasses and contact lenses. In most cases, spectacle and contact lens independence is achieved.
Do note that if you are beyond 45 years of age and require glasses for reading (a condition called presbyopia or “lau hua”), you will probably still need your reading glasses after LASIK. There are other options for presbyopia management which your LASIK surgeon will be able to discuss with you. Some people choose a vision correction method called monovision which leaves one eye slightly short-sighted to allow for close work, while the other eye is adjusted for distance vision. Monovision works well for some patients, and your eye doctor will help you decide if you are suitable for this.
Not everyone can have LASIK or will benefit from it. Your LASIK surgeon will advise you accordingly.
Generally, in order to undergo LASIK, you should:
Most importantly, you must have realistic expectations about the outcome of the procedure, and be willing to accept the potential risks associated with it. Fortunately, LASIK is very safe, and the results excellent, and most patients are extremely happy with how the procedure has changed their lives.
LASIK is performed as an outpatient procedure. Here is what happens:
In some cases, a contact lens that acts like a bandage is placed over the cornea to allow proper healing of the flap to occur. This will be removed by your LASIK surgeon, usually the next day.
Most patients are able to return to work a day or two later. Stabilization of vision takes a few weeks, and varies from patient to patient.
These include dry eye, fluctuating vision, hazy vision, haloes and glare in a dim environment and light sensitivity. Over- and under-correction may also occur, and a “top up laser” procedure called “enhancement” may be required in some cases. Serious side effects that can result in loss of vision are extremely rare, and these include severe inflammation, infection and corneal ectasia (weakening and thinning of the cornea)
Do not despair! Alternatives to LASIK are available. Dr Cordelia Chan performs a wide variety of refractive surgical procedures that aim to give good vision, and if you are not suitable for LASIK, there are likely to be alternatives for you. These include:
