Lasik Surgery - FAQ



Lasik Surgery



Lasik Surgery, unlike the eye exercises, has the "wow" factor.

If it is done properly, the visual results are immediate. The patient usually exclame delight at the almost immediate restoration of clear vision!



Lasik Surgery





It is a relatively short procedure, and normally done as an outpatient procedure, without the need for injections and using only numbing eye drops to anaesthetise the eye.

The healing phase is also fast and painless and post-op care is simple.

As Lasik surgery is a surgical procedure, it will carry with it all the attendant risks of any surgical procedure. While most patients who undergo Lasik are happy with the results, there are those who are less elated or who feel that the procedure did not quite meet their expectations. Therefore, it seriously behoves those contemplating Lasik surgery to act with caution and investigate the procedure thoroughly so that an informed decision can be made. That Lasik is an elective procedure, meaning that there is no medical necessity to have it done and you can choose to go for it as you wish, makes this process of informed consent all the more important.

Success Rate

The goal of Lasik is to reduce or eliminate dependence on spectacles and contact lenses permanently by the surgical reduction or elimination of myopic power. Note that in some cases, the doctor may deliberately aim for slight undercorrection.

Lasik when successful, will allow you to carry out most of your daily activities without the need to wear spectacles or contact lenses. If spectacles are needed, they are usually worn at night and will be of considerably reduced power and thickness.

Current results show that the vast majority (95% or more) of patients will see 6/12 or better without optical aids after treatment. This usually translates into -1.00 dioptres (100 degrees) or less of myopic power. Within this range, you will be able to enjoy participating in sports and be able to drive without the aid of glasses or contact lenses. Indeed, 6/12 is often taken as the the minimum vision requirement for driving. The American Academy of Ophthalmolgy reports that seven out of ten patients {70%} will achieve normal 6/6 or better vision.

Am I Suitable For Lasik Surgery?

You should not be suffering from any active eye diseases such as cataract, glaucoma, retinal detachment or keratoconus.



If you suffer from severe dry eyes or a past ocular herpes infection, you may also not be a good candidate. Also, be sure to tell your doctor if you or anyone in your family has ever had a cornea disorder, diabetes or autoimmune disorder. You should not be taking certain prescription drugs like oral prednisolone. These conditions may increase the risk of serious complications. Lasik cannot be done if you are pregnant. Persons with an obsessive nature or who have great difficulty finding glasses to suit their eyesight are also advised against treatment.

Your eye doctor (ophthalmologist) will perform a comprehensive eye examination for you. He will also counsel you on the procedure and you should in turn take this opportunity to address any concerns that you may have about the procedure.

Procedure of Lasik Surgery

The lasik surgery is usually performed with the patient either resting on a bed or in an reclining chair. The eye is first cleaned and draped. Numbing eye drops are instilled and a speculum is inserted to help prop the lids open. A tight pressure sensaton may be felt at this stage which is also considered to be the most uncomfortable part of the lasik surgery procedure. An instrument is used to mark the cornea surface and the actual lasik procedure now begins.

A suction ring is placed on the eye to provide a base for the microkeratome which is used to create the cornea flap. Suction is applied to hold the eye steady and to maintain the internal eye pressure while the cornea flap is being made. Do not be alarmed if your vision becomes dim or dark at this stage. You will hear a high pitch mechanical sound for about five to ten seconds. Suction is then released and vision returns. The cornea flap is now folded out of the way to expose the deeper layers of cornea tissue for the laser treatment phase.

For the laser treatment phase, you will be asked to fix your gaze at a blinking red light. The excimer laser is triggered and the high pitch clacking noise of the laser is heard and a slight smell may be detected. The laser is guided by information fed from the computer programme as it precisely sculpts the inner layers of the cornea according to your spectacles prescription. For myopia correction, the laser essentially reshapes the cornea curvature into a flatter curve. This part of the procedure will lasts about 15 to 45 seconds depending on the amount of correction required.

Once the laser stage is completed, the cornea flap is unfolded back into its original position. After a short wait of two minutes, the flap will bond itself back naturally without the need for stitches.

How soon can I see well after the lasik surgery?

Most patients will already notice much improved vision without glasses immediately after the lasik surgery procedure. However, the most dramatic improvement is noticed after resting the eye overnight. Most patients will see well enough to drive without glasses the second day after the procedure. Thereafter, a gradual improvement in vision is expected as further healing occurs over the next few weeks. Vision is usually stable in a month's time. Some patients may have trouble with glare and seeing haloes during the first few weeks. Those with naturally big pupils or with correction done for high myopia are more likely to be affected. In most cases, these complaints will lessen or go away after six months.
