Vision correction: all about eye surgery

Nearsightedness, farsightedness or astigmatism are common eye conditions described as refractive errors. These refractive errors can often be corrected with laser surgery. Eye surgeons perform laser procedures to reshape the cornea so that light is properly focused onto the retina in order to ultimately improve vision.

Laser vision correction developed during the 1980s, and continues to advance. Currently, there are three types of laser surgery that employ different techniques. This includes PRK/LASEK, LASIK and SMILE – all commonly performed surgeries that have become viable alternatives to glasses and contact lenses.
 

A cataract is one of the most common reasons for diminished vision quality, and affects most people as they age. It is also the most frequent cause of blindness worldwide. Patients often don’t realise they have cataracts until cloudy vision starts to dramatically impair their daily lives. Left untreated, a cataract may even lead to complete loss of vision. The good news is that a cataract can be treated easily and effectively with a safe, routine procedure. The replacement of the eye-lens blurred by a cataract with an Intraocular Lens (IOL) is currently performed over 20 million times per year worldwide*.
