What is Refractive Surgery?
Refractive surgery is a surgical procedure performed to correct the refractive error (spectacle power) of the eye. It is usually done to get rid of or reduce dependence on glasses and contact lens . It can be performed in a patient with stable refraction (glass power) after the age of 18 – 21 years. Complete medical history along with detailed eye examination is mandatory in all candidates, special Investigations like corneal topography (Pentacam, Orbscan), Anterior segment Optical Coherence Tomography (ASOCT) are performed to evaluate the shape, thickness and curvature of the cornea and other dimensions of the eye. After acquiring all the details, the eye surgeon (ophthalmologist) makes a decision regarding the available options of refractive surgery for the patient.
The current refractive procedures can be classified as Corneal procedures and Lens based surgery.
We prefer Phakic Lens implantation to remove . dependency of glasses. In comparison to LASIK in phakic Lens implantation there is no alteration of Cornea thickness. Advantage in Phakic Lens is in those patients LASIK is not possible due to thin cornea patient can be spectacles free by phakic lens implantation.
