Nearsightedness, farsightedness or astigmatism are common eye conditions described as refractive errors. These refractive errors can often be corrected with laser eye surgery also known as laser vision correction.

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 Lenticule Extraction for example with ZEISS SMILE – all commonly performed surgeries that have become viable alternatives to glasses and contact lenses.
