Correction of Refractive Errors

The methods for correcting refractive error include wearing spectacles, contact lenses or refractive surgery. These essentially serve to redirect the light rays entering the eye so that images are focused sharply on the retina. The choice of correction of refractive error varies from individual to individual, and often depends on the patient’s lifestyle requirements and personal preference.

Spectacles
Spectacles are the cheapest, safest and easiest method to correct refractive errors. They can correct most refractive errors effectively. For people who have presbyopia, bifocal or progressive spectacles may be used help with both distance vision as well as near reading.

Contact Lenses
Contact lenses are plastic lenses that are placed on the cornea which can correct refractive errors. There are various types available, including soft and rigid gas permeable lenses. People should not overuse contact lenses and must maintain proper contact lens hygiene to prevent potentially serious complications like corneal infections.

Refractive Surgery
Refractive surgery refers to surgical correction of the refractive error of the eye. The most common refractive surgical procedure in the world today is LASIK surgery, because of its well established effectiveness, safety and fast visual recovery. Other refractive procedures include photorefractive Keratectomy (PRK) and EPILASIK.
