title: Comparison of intraocular lenses from the standpoint of postoperative glare disability.
abstract: Although implantation of an intraocular lens provides excellent postoperative visual acuity, some factors such as disability glare have attached importance to qualitative evaluation of the visual function of artificial pseudophakia. In order to find out which factor most greatly contributed to glare disability, four types of intraocular lens, convexplano, biconvex anterior more curved, posterior more curved, and equiconvex, were prospectively implanted. The patients were 21 men and 63 women, ranging in age from 39 to 92 years (mean +/- SD = 70.9 +/- 10.1 years). Glare disability, examined by the Titmus Miller-Nadler Glare Tester, was found to be significantly correlated to types of intraocular lens, refractive power of intraocular lens, but not to age of patients or strength of postoperative astigmatism. The lower glare disability index value was found in patients implanted with posteriorly more curved biconvex or equiconvex surface, and within a range of 18.5-22 D compared with those implanted with convex anterior or convex-plano surface, and 22.5 D or more.
