LASIK (laser-assisted in situ keratomileusis) is an abbreviated term for what is commonly referred to as laser eye surgery. It is used for the treatment of myopia, hyperopia, and astigmatism. It works by reshaping the eye's cornea, often the cause of vison problems. It is usually permanent, removing the need for glasses or contact lenses.
WHAT TO EXPECT
A qualified ophthalmologist. You will require a full eye examination and diagnosis of underlying conditions. If one eye is too bad, the risk of surgery will be too great and will not be performed. The cornea is measured and a suction ring is used to keep the eye in place. Slight and resolvable bleeding in the eye occurs at this stage. The laser then remodels the areas of the eye required; vision becomes blurred. Post-op antibiotics and anti-inflammatory eye drops are prescribed.
Surveys of LASIK find rates of patient satisfaction between 92 and 98 percent.
Risks include failure to achieve any improvement in vision, development of new visual problems, corneal infection (though antibiotic is designed to avoid this) and what is known as ‘flap complications’.
