Refraction of eye is affected by all except:
Correct Answer: Optic atrophy
Description: Optic atrophy does not have any effect on the refractive status of eye. Most Impoant factor is axial length (Q) for myopia* Other impoant factors that determine the refractive power Keratometry means curvature of cornea Lens- thickness , position and sclerosis as the lens has highest refractive index* Remember 1 D change in axial length cause almost 2.5 D change in refractive error* 1 D change in corneal curvature cause 6 D change in refractive error*
