Refractive
surgeries are designed to alter the corneal curvature or change
lens power to allow light rays to focus on or near the retina,
thus improving vision. The purpose is to achieve best vision
and minimize dependence on eyeglasses and contact lenses.
The most performed refractive surgery is called LASIK,
for correction of myopia, hyperopia and astigmatism. Hong Kong Sanatorium & Hospital
is the first hospital in Hong Kong to employ LASIK surgery techniques.
