title: Schematic eye predictions of relative spectacle magnification in unilateral aphakia.
abstract: Computer ray tracing provides a simple technique for investigating binocular relative spectacle magnification (BRSM) in the patient with unilateral aphakia. BRSM is defined as the retinal image size in the corrected aphakic eye relative to the retinal image size in the corrected phakic eye. The influence of preoperative ametropia and the mode of correction on BRSM is investigated, using Gullstrand's number 2 schematic eye as a model.
