Clinical prediction of postsurgical aphakic refractive correction.

A simple clinical predictor of the amount of spectacle convex lens power that will be needed to correct the refractive error of an aphakic patient after cataract surgery is developed based on clinical measures of anterior corneal surface power (keratometer measurements) and axial length. This predictor derived from matrix optics is compared to previous ones developed by Binkhorst and Sanders et al. using different methodologies.
