Abstract
Purpose. To study the effects on visual function of glistenings and folding marks in AcrySofs (Alcon) intraocular lenses (IOLs). Setting. Department o f Ophthalmology, Dokuz Eylul University, School of Medicine, Izmir, Turkey. Methods. This study included 91 eyes that had phacoemulsification and in-th e-bag Acry-Sof IOL implantation. Slitlamp, visual acuity, and contrast sens itivity evaluations were used to assess all cases, Observations of folding marks and glistenings in the IOL optic were noted, The glistenings were gra ded from 0 to +4. Eyes with coexisting pathology that could affect visual a cuity (n = 15) were excluded from the study. After the exclusion, the visua l acuity and contrast sensitivity in 28 eyes with glistenings were compared with those in 48 eyes without glistenings. Results: Localized folding marks away from the central visual axis of the I OL were identified in 25 eyes (27.4%). Glistenings were observed in 34 eyes (37.1%), 6 of which were excluded for coexisting pathology. There was no s tatistically significant difference in visual acuity and contrast sensitivi ty at low or medium spatial frequencies between eyes with glistenings and t hose without (P > .05); however, a statistically significant difference was noted at the high spatial frequency (P < .01). There was no difference in visual acuity or contrast sensitivity between eyes with folding marks and t hose without (P > .05). Conclusion: Although glistenings and folding marks were observed after the implantation of AcrySof IOLs, they did not significantly affect visual func tion, (C) 2001 ASC RS and ESCRS.
