Abstract
To evaluate the refractive consequences and complications of inadvertently implanting reverse-inserted foldable posterior chamber intraocular lenses (IOL)from May 1997 to December 1998, a total of 8 eyes (8 patients) were analyzed.One of these patients was male, seven were female and the mean age of patients was 70 years.The used IOLs were Chiroflex 32-C31SX (4 eyes), Corneal SP57T (2 eyes), and AcrySof MA60BM (2 eyes).The SRK-II formula was used to predict target spherical equivalent refractive error (SE).Actual postoperative SE were determined at 1 year after surgery and these results were compared with nonreversed control group (29 eyes). The target postoperative SE were subtracted from the actual postoperative SE to calculate diopter differences, between the actual SE and the target SE.The mean (+/-standard deviation)diopter difference in reversed IOL group was -0.95D +/-1.04D (ranged from -2.81D to 0.87D)more myopic than control group :-0.13D +/-0.98D (ranged from -3.23D to 1.47D), but the differ-ence (0.82D)was not statistically significant (p=0.07).The mean postoperative 1 year visual acuity in reversed IOL group was 0.74 +/-0.24, and in control group 0.76 +/-0.22;the difference (0.02)was not statistically significant (p=0.83).Posterior capsular opacity (PCO)developed in only 1 eye in reversed IOL group after 1 year postoperatively, and it occurred in 1 eye in the control group.No statistically significant difference was found in the incidence of PCO between the two groups (Chi-Square test, p>0.05).There-fore reversed IOL group is likely to produce a satisfactory refractive result and not to warrant the risks of repositioning the lens.
Key Words: Posterior capsular opacity;Reverse-inserted foldable intraocular lens;Spherical equivalent
