Accuracy of lens power calculations with the biconvex and meniscus intraocular lenses.

In a prospective study, intraocular lens power calculations were within +/- 0.50 diopter of the final refraction in 77 of 88 eyes (87.5%) with a biconvex lens and in 41 of 90 eyes (45.5%) with a meniscus lens. The more precise power calculations with the biconvex intraocular lens seemed to be related to the superior optical design of the lens, with its close configuration to a normal crystalline lens.
