Posterior iris fixation of iris-claw IOL implantation in 25 cases

Objective To evaluate the therapeutic efficacy of posterior iris fixation of iris-claw intraocular lens(IOL) implantation on aphakia eyes with non-posterior-capsule or less capsule supporting IOL.Methods Iris-claw IOL were selected to implant behind the iris for operation in 25 aphakia eyes of 25 patients with non-posterior-capsule or less capsule supporting IOL.After following up for 3 months,visual acuity,corneal endothelial cells counting,anterior chamber depth and mean intraocular pressure,the position of IOL and complications were observed.Results After following up for 3 months,postoperative average uncorrected visual acuity 0.5±0.2 was better than the preoperative average best corrected visual acuity 0.3±0.1,there was significant difference between pre- and post-operation(P0.05),and 18 eyes(72%)were better than the preoperative ones.There was no significant difference between preoperative and postoperative mean counts of corneal endothelial cells,anterior chamber depth and mean intraocular pressure(all P0.05).The position of IOL retained center well,and complication such as retinal detachment was not found.Conclusion Posterior iris fixation of the iris-claw IOL implantation is safe and effective for non-posterior-capsular or less capsule supporting IOL aphakia eye.
