Refraction Errors & Correction

Various methods to correct refractive errors

Spectacles and Contact Lens

Spectacles Contain lenses that alter the incoming rays of light to enable them to focus on the retina.

Contact Lenses perform the same function as spectacles but are placed in the cornea. They provide improved cosmesis and better quality of vision, especially for higher refractive errors.

In the Apollo Eye clinic trained optometrists perform refraction aided with auto refraction, keretometry and corneal topography. Contact lens fitting is done for both soft and semi soft lens.

Refractive errors can be corrected through surgery

LASIK is an exciting surgical procedure that is capable of correcting a wide range of near sightedness (myopia), farsightedness (hyperopia) and astigmatism. LASIK is the acronym for laser assisted in-situ keratomileusis. The name refers to the use of a laser to reshape the cornea without invading the neighboring cell layers. Lasik is currently the most commonly performed refractive procedure in the United States and in India. Lasik has been performed internationally for approximately 10 years.

It was first performed in clinical trails in the US in 1991. It was officially approved in 1996 in the U.S. It is important to note that the major components of the procedure have a long history. Ophthalmologists have been reshaping the cornea for over 50 years creating a protective layer of tissue for over 35 years, and using the excimer laser since the 1980's
