Abstract
Various kinds of multifocal intraocular lenses(IOLs) have been developed for the improvement of near and far visual acuity after cataract operation. This prospective study was performed to compare a function of AMO ARRAY multifocal IOL(Array group) with conventional monofocal IOL(Mono group). Each type of IOL was implanted into 25 eyes and uncorrected visual acuity(UCVA) and best corrected visual acuity(BCVA) at near, intermediate and far distance were evaluated before and 2 months after operation in both groups. Contrast sensitivity, photophobia and glare were also evaluated as subjective symptoms in both groups. Mean UCVA at distant and near distance before operation was 0.23+/-0.15 and 0.25+/-0.20 in mono group, and 0.13+/-0.11 and 0.14+/-0.11 in Array group. Mean UCVA/BCVA at distant and near distance 2 month after operation was improved to 0.79+/-0.28/0.87+/-0.27 and 0.34+/-0.15/0.82+/-0.26 in mono group and 0.83+/-0.19/0.86+/-0.19 and 0.50+/-0.15/0.79+/-0.15 in Array group. The difference of UCVA at near distance was statistically significant(P<0.05), while that of BCVA at near and far distance was not statistically significant between two groups(P<0.05). Array group had less contrast sensitivity at all spatial frequencies(1.5, 3, 6, 12, 18 cycles/degree) and more glare than the mono group after operation. AMO ARRAY multifocal IOL induces a good result of visual rehabilitation in both near and far distance, but it may cause more glare and less contrast sensitivity than the monofocal IOL.
