摘　　要：Objective:To report the outcomes in eyes in which a Sinskey-type conventional posterior chamber intraocular lens(PC-IOL)was fixed in the anterior chamber and fol-lowed up for an average of 10years.Me thods:Twenty-one eyes were included in the study.The I OLs were conven-tional hard PC-IOLs,13.0mm in overa ll length with6.0-mm polymethy lmethacrylate opt ic and polyvinylidene fluoride loops that tilted 10°anteriorly.Results:At im-plantation the corneal endothelial cell density in 13of 21eyes was 382to 1580cells /mm 2 owing to the previous im-plantation of iris-clip or iridocap sular IOLs.The overall postoperative corneal endothelial cell loss was 30.9%.Six of 14eyes with a preoperative corneal endothelial cell den-sity less than 2000cells /mm 2 developed bullous keratopa-thy.Although serious complication s did not occur in 7eyes with a cell density exceeding 2000cells /mm 2 ,an average corneal endothelial cell loss of 26.5%still occurred.Ex-cept for 2eyes,all loops were fixed a t the scleral spur and a slight pupillary transformation occurred in only 1eye.Conclusions:Although this procedure is easy to performand pupillary transformation does not o ccur,it is not recom-mended for aphakic eyes owing to the h igh corneal en-dothelial cell loss after an average10-year follow-up.Objective:To report the outcomes in eyes in which a Sinskey-type conventional posterior chamber intraocular lens(PC-IOL)was fixed in the anterior chamber and fol-lowed up for an average of 10years.Me thods:Twenty-one eyes were included in the study.The I OLs were conven-tional hard PC-IOLs,13.0mm in overa ll length with6.0-mm polymethy lmethacrylate opt ic and polyvinylidene fluoride loops that tilted 10°anteriorly.Results:At im-plantation the corneal endothelial cell density in 13of 21eyes was 382to 1580cells /mm 2 owing to the previous im-plantation of iris-clip or iridocap sular IOLs.The overall postoperative corneal endothelial cell loss was 30.9%.Six of 14eyes with a preoperative corneal endothelial cell den-sity less than 2000cells /mm 2 developed bullous keratopa-thy.Although serious complication s did not occur in 7eyes with a cell density exceeding 2000cells /mm 2 ,an average corneal endothelial cell loss of 26.5%still occurred.Ex-cept for 2eyes,all loops were fixed a t the scleral spur and a slight pupillary transformation occurred in only 1eye.Conclusions:Although this procedure is easy to performand pupillary transformation does not o ccur,it is not recom-mended for aphakic eyes owing to the h igh corneal en-dothelial cell loss after an average10-year follow-up.
