Abstract
Lens shape varied with the ocular parameters. A recommended range of intraocular lenses is plano-convex (with the curved shape facing the cornea) to equi-convex. Compared with conventional poly(methyl methacrylate) lenses (1.492 index), optimum lens shapes of low index lenses were less sensitive to changes in eye parameters and lens fitting position. The magnitudes of aberration of pseudophakie eyes varied more with changes in lens shape and lens position in low index lenses than in conventional lenses. 1Reprint requests to David A.
