Lasik or LASIK surgery, which stands for laser-assisted in situ keratomileusis, is a laser surgical procedure for correcting vision problems such as myopia, hyperopia and astigmatism. Persons who were elected as candidates for this procedure have found it to be very effective in solving their vision problems. One of the major advantages of Lasik over other forms of eye surgery is that it is much less invasive, with significantly shorter and easier recovery.
Before and during Lasik surgery
Many people become worried and anxious before any kind of surgery. Lasik is done while the patient is awake and can see everything that goes on around him or her, which may increase the feeling of anxiety. It is recommended to talk extensively to doctors and surgeons who will perform the surgery. They will guide the patient through the procedure, explaining every little part of it, so the patient can feel reassured and safe.
No particular preparation is required for Lasik surgery. The procedure lasts from 30 to 60 minutes and the patient is advised to go to the bathroom before it and to drink some water, so he or she can be comfortable during surgery.
The eye is not supposed to move during the procedure, which is why special drops are applied to stabilize it, which may feel strange and somewhat unpleasant. The eye is kept open with speculum and the patient will feel the urge to close the eyes or blink as the instruments approach the eye, but will not be able to do so.
Once the preparations are done, an incision will be made in the cornea to create a flap. The flap is then moved to allow the laser to make necessary adjustments to the eye. The flap will be secured back in its place once the adjustments are done. During this part, the patient may experience changes in vision, which is why it is advised to stay as relaxed as possible.
After Lasik surgery
Once everything is done, the eye will be covered for a while. The cover is usually supposed to be worn in bed too, so the eye is not rubbed or scratched accidentally. Wearing the cover is important so the flap can stay in place and not get infected.
The actual results of the surgery will not be immediately visible. The vision may feel awkward because the eyes need to adjust to the changes that have been made. It usually takes several days for the results to take full effect.
Healing after Lasik surgery is usually quick and complete. It is, however, necessary to have regular consultations with the doctor who will control the eyes and see if everything is going well.
During the recovery period some itching and irritation may be expected, like there is a speck of dirt in the eye. The vision will also be blurry, which will gradually improve over several days, but immediately after the surgery the patient will require some assistance in getting home.
