Surgery Overview
Laser in-situ keratomileusis (LASIK) is the preferred
procedure for correcting
(hyperopia). In LASIK, a thin flap is
made on the cornea using a blade or laser. The flap is lifted, and a laser is
applied to the central corneal tissue. The laser makes contact with the
in a circular pattern around the central
optical zone. This changes the profile of the cornea, making it steeper. The
laser removes tissue from the cornea very precisely without damaging nearby
tissues. The flap is then replaced, allowing for rapid healing.
LASIK is performed in a surgeon's office or same-day surgery
center, It does not require a hospital stay.
This procedure may not be available in all areas, but it is done in
most large cities.
What To Expect After Surgery
Most people have little or no pain after LASIK surgery. And most people who have LASIK see quite well the next day.
Your doctor will want you to come in for an exam the day after the
surgery and for regular follow-up exams for about 6 months.
Following LASIK surgery to correct farsightedness:
- You will feel irritation and scratchiness in
the eye the day of surgery. And a lot of tears may come out of your eye.
- You may need to wear an eye shield for a few days after
surgery.
- Your vision may be hazy or blurry for a few days or a week
after surgery. Do not drive until your vision has cleared.
- Your
doctor may prescribe eyedrops to reduce inflammation and the risk of infection.
You may need to use them for several months after surgery.
- You
should avoid vigorous sports, eye makeup, and any activities during which water
may get in your eye. The surgeon may advise you to shower before the
surgery, then avoid showering for a day or two afterward to avoid getting water
in the eye.
- Dry eye symptoms are common but usually
temporary.
Why It Is Done
LASIK surgery may be used to correct mild to moderate
farsightedness. Treating severe farsightedness is not as effective as treating
mild or moderate farsightedness.
LASIK is an elective, cosmetic procedure, done to correct
farsightedness in otherwise healthy eyes.
The procedure may not be done for people who:1
- Have not had stable vision for at least 1
year.
- Are under age 18.
- Are pregnant, because pregnancy
may cause changes in the cornea.
- Have a disease or abnormality of
the cornea, such as keratoconus or corneal edema, or another eye disease, such
as advanced or uncontrolled glaucoma or cataracts.
- Have poorly
controlled diabetes or complications of diabetes that affect
vision.
- Have significant risk of injuring their cornea from a job
or hobby.
