Iris-claw intraocular lens implantation: Efficiency and safety according to technique

Abstract

Seventy-six eyes (75 patients) were included. The postoperative uncorrected (UDVA) and corrected (CDVA) distance visual acuities were significantly better than the preoperative acuities (P < .001). The UDVA was 20/40 or better in 41.7% of patients, and had the CDVA was 20/40 or better in 68.1% of patients. The mean UDVA was significantly better in the scleral tunnel incision group (0.29 logarithm of the minimum angle of resolution [logMAR] ± 0.41 [SD]) than in the corneal incision group (0.66 ± 0.45 logMAR) (P < .001). The mean surgically induced astigmatism in the scleral tunnel incision group (0.73 ± 0.62 diopter [D]) was significantly lower than in the corneal incision group (2.49 ± 1.36 D) (P < .001). Although endothelial cell loss was lower in the retropupillary position, the difference was not significant (P = .07.) CONCLUSION: Implantation of the iris-claw IOL in the retropupillary position and through a scleral tunnel incision was an effective and safe alternative to aphakia without capsule support, providing better refractive results compared with other techniques.
