Arquivos Brasileiros de Oftalmologia , 2009, DOI: 10.1590/S0004-27492009000400017
Abstract: purpose: to compare the visual outcome, contrast sensitivity and wavefront analysis of patients that underwent cataract surgery and implantation of acrysof sn60d3 multifocal intraocular lens with those who received the acrysof sn60at monofocal iol. methods: this was a prospective clinical trial of forty eyes that received the multifocal iol and thirty-two eyes that received the monofocal iol after phacoemulsification. results: values for total and spherical aberrations in the multifocal group were statistically lower than in the monofocal group. in the monofocal group, 75% achieved uncorrected intermediate visual acuities between jaeger 1 and 6. in the multifocal group, 75% of the eyes achieved more than jaeger 6. at least 87.5% of the multifocal group and 6.3% of the monofocal group achieved monocular uncorrected near acuity of 20/30 (j2, n5) or better. and 90.0% of the eyes in the multifocal group and 37.5% in the monofocal group achieved an uncorrected near acuity of 20/40 (j3, n6) or better. the mean spherical error was 0.11 d in the multifocal group and -0.18 d in the monofocal group (p=0.0379). the sn60d3 group compared to sn60at group had low contrast sensitivity (log units) with statistically significant differences in 6.0 cpd in photopic conditions (p=0.014) and the sn60d3 group compared to sn60at group had higher contrast sensitivity (log units) under mesopic conditions (p=0.044). conclusion: the multifocal iols induced less spherical aberration than monofocal iols and predictably good uncorrected distance and uncorrected near acuities. however, contrast sensitivity was lower in the multifocal group.
