To compare the near and intermed. visual function in bilateral cataract and refractive lensectomy (RL) pts receiving either ReSTOR/ReSTOR or ReZoom/ReSTOR multifocal IOLs.
56 pts received bilateral ReSTOR (RS) lenses (cohort I; mean f/u=14 wks). Subsequently, 30 pts received the ReZoom (RZ) lens in the non–dominant eye and the RS lens in the dominant eye (cohort II; mean f/u=7 wks). Unilateral and bilateral Jaeger near vision was measured at the pt’s best focal distance. Unilateral and bilateral intermed. vision was measured at pt’s arms length. All pts with > 0.75D of postop astig underwent AK. Incidence of subjective near and intermed. visual complaints were recorded.
A statistically signif. difference (p=.0001) was detected when comparing bilateral intermediate RS/RS=J 3.64 vs. RZ/RS=J 2.38. No signif, difference was observed at near with bilateral RS/RS=J 1.02 vs. RZ/RS=J 1.05. The comparison of unilateral RZ vs. RS eyes (cohort II; n=30) revealed a signif. difference (p=.0001) for intermed. vision (RZ=J 2.95 vs. RS=J 4.38), but no signif. difference at near (RZ=J 1.76 vs. RS=J 1.38). 13 of 56 pts (23.2%) in cohort I (RS/RS) volunteered complaints regarding intermed. vision. None of the 30 pts (0%) in cohort II (RZ/RS) volunteered complaints regarding intermed. vision. In cohort I (RS/RS), 77% (10/13) of the intermed. complaints were those receiving lensectomies. 100% (10/10) of these RL pts were < 60 y.o. age. 27% (10/37) of all the RL pts in the RS/RS cohort had voluntary intermed. complaints and all 10 were < 60 y.o. age. In the RZ/RS cohort, 19 of 30 pts (63%) were RL pts with a mean age of 55 years and no voluntary intermed. visual complaints were observed.
1)The objective bilateral intermed. visual function of the RS/RS cohort (J 3.64) was significantly less than (p=.0001) the RZ/RS cohort (J 2.38). No signif. differences between the cohorts were observed for bilateral near vision. 2) Overwhelmingly greater subjective voluntary intermed. visual complaints 13/56 (23.2%) were observed in the RS/RS cohort vs. the RZ/RS cohort (0/30). 3) In the RS/RS cohort, 10/13 (37%) of the intermed. complaints were in RL pts, and 10/10 (100%) of these RL pts were < 60 y.o. age. 4) When implanting bilateral multifocal implants, the combination of RZ/RS appears to effectively mitigate voluntary intermed. vision complaints that were previously observed in RS/RS pts. 5) The relative risk of intermed. visual complaints in pts receiving bilateral ReSTOR lenses appears to increase with decreasing age, and is greatest in RL pts under 60 y.o. age.
