Abstract

Purpose: : The estimation of refractive error after small incision cataract surgery (CE) with an intraocular lens (IOL) depends on accurate biometry, placement of the IOL within the capsule, an astigmatically neutral incision, and optimization of the IOL constant. Biometry with partial coherence interferometry (Zeiss IOLMaster) is rapid and precise, and the instrument software permits the clinician to optimize the lens constant for 5 IOL calculation formulas. We have reviewed 200 cases of CE with the Acrysof SN60WF IOL (Alcon Laboratories) to determine if the IOL constant varies with axial length.

Methods: : All procedures were performed by a single surgeon, with a temporal 2.6 mm clear cornea incision. Manifest refraction was determined at least 4 weeks after surgery. The database included keratometry and axial length determined by the IOLMaster, IOL power, date of procedu...
