Abstract

Lens-based surgery, in the form of cataract surgery or refractive lens exchange surgery for refractive error, is growing each year as the population ages and as the improved IOL choices allow younger patients to undergo lens exchange for surgical refractive correction. Because of increasing patient expectations, the accuracy of these calculations is important. The accuracy of the calculations depends on the choice of an appropriate formula for calculating IOL, accurate measurement of corneal power and axial length, lens thickness, anterior chamber depth, and an accurate estimation of effective lens position.
