Laser in-situ keratomileusis is standing for LASIK. This surgery used to correct vision in people who are nearsighted, farsighted, or have astigmatism.
Reshaping the cornea, the clear front part of the eye is done in this laser vision correction surgeries. Then light traveling through the cornea properly focused onto the retina located in the back of the eye.
During LASIK, the eye surgeon cuts across the cornea of the eye and raises a flap of tissue and carries out reshaping to correct vision.
General requirements for LASIK
- Being age 18 or older
- Having healthy eyes
- Not needing a change in eyeglass or contact lens prescription over the past three years
- Having vision that refractive surgery can correct
How the LASIK Done?
LASIK is performed while the patient is under local anesthesia in the form of eye drops and usually takes about 10 minutes to complete. Patients may also request mild sedation.During LASIK eye surgery, an instrument called a microkeratome or femtosecond laser is used to cuts across the cornea of the eye to create a thin flap in the cornea. The cornea flap is then painlessly peeled back and the underlying corneal tissue is reshaped to focus light onto the retina using another laser. Finally, the corneal flap is put back in place.
After the LASIK
The doctor will prescribe some eye drops to prevent infection and inflammation and eyedrops to keep your eyes moist. These drops may cause a momentary slight burn or blurring of your vision when you use them. Plan to have someone drive you home after surgery.
Vision may be blurry and hazy for the first day, but most patients notice improved vision within a few days of surgery.
You will have to revisit your doctor for an evaluation 24 to 48 hours after LASIK. As well as at regular intervals within the first six months.
