Laser-Assisted In Situ Keratomileusis (LASIK) is the most commonly performed laser eye surgery to treat eye problems like myopia (near-sightedness), hyperopia (far-sightedness), and astigmatism.
However, this laser vision correction surgery depends on several factors, including a person’s health and the conditions affecting their eyesight.
How is it done?
A thin layer of corneal tissue is removed using an excimer or UV laser. Laser vision-correction surgeries reshape the cornea to allow light travelling through it to focus correctly on the retina at the back of the eye. After the laser surgery, the cornea becomes thinner.
This procedure is an outpatient surgical procedure and takes only 10-15 minutes to perform it.
The procedure is carried out only after numbing the surface of the eye using an anaesthetic eye drops, and you will be awake during the entire process. This laser vision correction procedure may be done on one or both eyes during the same session.
Immediately after the surgery, the surgeon will have you rest for a bit. You may feel a temporary burning or itching sensation just after the procedure.
LASIK eye correction surgery is dependent on the severity of your visual errors. And only an ophthalmologist can determine whether it is right for you. However, here is some standard information to help in making your decision. Also, it would be prudent that you consult the best LASIK surgery hospital in Delhi to increase the chances of successful vision correction.
Who qualifies for laser eye surgery?
- The patient must be above 18 years of age.
- Uses eyeglasses or contact lenses (or both) on prescription for at least 2 years.
- Steady eyesight prescription for at least 1 year.
- No history or active corneal disease (corneal ulcers, keratoconus, diabetic retinopathy, macular degeneration, or glaucoma).
- Not pregnant or nursing.
Who must stay away from LASIK?
- Persistent dry eyes.
- Patients suffering from autoimmune diseases such as rheumatoid arthritis, lupus, HIV.
- Severe near-sightedness.
- Large pupils that are prone to widening in dim light. This can result in glare or halos after the surgery.
- If you participate in sports like martial arts or boxing where blows to the face are frequent, then the eye surgeon would not prefer performing LASIK on you.
- It is essential to be 21 years of age with a stable prescription for at least a year. However, there is no upper age limit for the procedure. But patients who have cataracts may not be eligible for the surgery.
- Presbyopia (the decreasing ability for eyes to see close up, usually happens after 40 years of age) is another reason you might not be considered for LASIK surgery.
Risks of LASIK surgery
- Corneal infection
- Dry eyes
- Glare or halos
- Light sensitivity
- Corneal scarring
- Temporary red or pink patches
You must get an eye test done and discuss your options, benefits, chances of success, and risks of LASIK with the eye surgeon you want to go ahead with. If you are not an ideal candidate for LASIK, they will suggest other possible options to help correct your vision.
