LASIK eye surgery is the first type of surgery many people think of when they want to stop wearing contact lenses or glasses, but it’s not the only option. Some people have eye problems that cannot be corrected by LASIK or another type of laser vision correction, and other people have very thin corneas or another medical condition that prevents laser eye surgery. Fortunately, there are a number of non-laser vision correction options for these patients.
Implantable contact lenses
A non-laser vision correction procedure are phakic intraocular contact lenses for both nearsighted and farsighted patients or those with astigmatism. The surgeon attaches the lens to the iris or places it between the iris and the lens of the eye. You do not feel these contact lenses and do not require maintenance. This procedure is reversible if you have any negative effects or if they don’t seem to be working.
The operation itself takes about half an hour and is performed under general or local anesthesia. Most ICL patients see excellent from the next day. This procedure is recommended for some patients who are very nearsighted and ineligible for LASIK because too much of the cornea would need to be removed or for people with very thin corneas that would make LASIK risky.
INTACS corneal rings
INTACS are small C-shaped perspex rings. They reshape the curvature of the cornea when placed in it. INTACS corneal rings can correct mild myopia or improve vision when the patient has keratoconus, a disease in which the cornea is deformed.
INTACS takes about thirty minutes to insert and anesthetic drops are used during this non-laser vision correction procedure. It may take several months for your vision to improve, but sometimes it goes much faster. This procedure is reversible.
Cataract Eye Surgery and IOLs
Cataract is a clouding of the natural lens in the eye. The light passes through the lens and is scattered, resulting in out-of-focus or blurry vision. LASIK cannot treat cataracts, so another type of surgery is required. An artificial lens, known as an intraocular lens or IOL, is implanted in your eye to replace the cloudy lens.
The three types of IOL are monofocals that correct one segment (usually far) of your vision, multifocals that correct a field of view (from near to far), and accommodative lenses that move with the eye and allow for a range of focus.
Cataract surgery takes a few hours. Before the operation, your eyes will be treated with anesthesia and eye drops. During the surgery, a small incision is made in the eye and a small instrument is used to remove the lens. The surgeon will then place the IOL in the eye.
Depending on your eye problem and the level of vision correction required, non-laser vision correction may be a good idea for you. It’s a good idea to discuss different options with your doctor first and listen to his recommendations.
