Abstract
The cornea serves as the transparent ‘window’ of the eye that allows the entry of light. The collagen fibrils that are present in the cornea are interwoven and are responsible for its mechanical strength. It also protects the inner components of the eye from physical injury and maintains ocular contour. Cornea contributes more than two thirds of the total refractive power of the eye. The regular arrangement of collagen fibres in the corneal stroma accounts for the transparency of this tissue. Corneal shape in addition to its transparency is critical for light refraction, the shape of the cornea is prolate i.e.it is flatter in the periphery and steeper centrally, which creates an aspheric optical system. Changes in the corneal shape results in various types of optical aberrations leading to a compromise in the best corrected visual acuity. In our study we conclude that: 1. Rose K is a viable treatment option in Keratoconus. 2. Rose K lens provides improved visual acuity in patients who are not adequately corrected by spectacles and conventional contact lenses. It delays the need for surgical intervention thereby decreasing patient morbidity.
