LASIK (Laser-assisted In Situ Keratomileusis), is among the most commonly performed laser eye surgeries or corrective eye surgeries today, to treat myopia (near sightedness), hyperopia (far sightedness) and astigmatism.
Like other types of refractive surgery (surgical procedures that correct common vision); the LASIK procedure reshapes the cornea to enable light entering the eye to be correctly focused onto the retina so you can have clearer vision.
LASIK has gotten more popular today as it is pain-free, and the procedure is completed in less than 30minutes. The results — improved vision without glasses or contact lenses; in as little as 24 hours!
The process begins with your eye doctor performing a thorough eye exam to ensure your eyes are healthy enough. The shape and thickness of your cornea; pupil size, refractive errors; and any other eye conditions you have will be evaluated. The moistness of your eyes will also be assessed, and a precautionary treatment may be advised to reduce your risk of developing dry eyes after LASIK.
LASIK is performed on each eye separately, taking only about 5to 10 minutes per eye. The eye surgeon uses a mechanical surgical tool called a microkeratome or a femtosecond laser to create a thin, circular "flap" in the cornea. This hinged flap is then folded back to access the underlying cornea. The laser light pulses now painlessly reshape the cornea (you may feel some pressure on your eye) and the flap is laid back in place, covering the area where the corneal tissue was removed. The cornea is allowed to heal naturally. You may be given only topical anaesthetic drops to apply, as you will not have any bandages or stitches.
Patients could experience blurry vision and some haziness immediately after the surgery; however, clarity will improve by the next day. Eyesight will stabilise and continue to improve over the next few days. For most people, vision improves immediately.
You may even be able to go to work the next day, but most doctors advise a couple of days of rest. Also, it is recommended that you refrain from strenuous exercise for at least 7-10 days, as this can traumatise the eye and affect healing.
Remember to schedule your follow-up appointment with your eye doctor or LASIK surgeon the day after surgery.
