Also known as laser in-situ keratomileusis, LASIK surgery is an innovative eye procedure used to address refractive vision issues. LASIK is performed to correct such vision difficulties as farsightedness, nearsightedness, or astigmatism.
During a LASIK procedure, the surgeon makes an incision over the eye’s cornea. This enables him or her to raise a flap of tissue and reshape the cornea. As a result, this procedure offers a number of benefits to the patient. Some of the advantages include the following:
- No pain is experienced during a LASIK procedure.
- The vision is improved right after the surgery. Most patients enhance their vision to 20/40 or better. A large number of patients can achieve 20/20 vision.
- The procedure is permanent.
- After the procedure, most patients experience a remarkable reduction in the need to wear glasses. In some instances, patients do not need to wear eyeglasses at all.
Preparing for a LASIK Surgery
When you look for an eye clinic in Singapore, it is advantageous to choose one that features LASIK in its listing of vision services. Because LASIK is such an innovative solution to vision correction, patients want to know more about the process. In order to prepare for the surgery, you need to do the following:
- If you wear contact lenses, you need to stop wearing them before the surgery. That means switching to glasses for a couple weeks prior to the procedure.
- If you wear eye makeup or apply eye cream, either of these applications must be stopped the day before, day of, and day after the surgery. Doing so will reduce the risk of an eye infection.
- After the procedure, you need to have someone pick you up as you will not be able to drive. You will probably still feel the effects of the medicine given before the procedure. In addition, your vision may be slightly blurred.
A Laser Is Used for the Procedure
When a LASIK procedure is performed, a laser is used for the surgery. The laser is programmed to get rid of a specific amount of tissue from the cornea. Therefore, the cornea can be elevated or flattened as needed. The surgeon takes measurements of the patient’s cornea and notates any irregularities prior to the surgery.
After the Surgery
After a LASIK procedure, your eyes may be watery or they may itch and burn. Whilst you can see, again, the vision is usually a bit blurred. The doctor normally gives patients pain medicine and eye drops to reduce any discomfort.
It normally takes about three months before the vision stabilises and the eyes fully heal. A follow-up appointment a couple days after the surgery is usually scheduled. Some of the risks of the procedure include sensitivity to glare, dry eyes, excess tears, or the appearance of halos around bright lighting.
