To evaluate whether retropupillary fixation of the iris-claw intraocular lens (IOL) is a safe and effective treatment option in children with large lens subluxations.
Fourteen eyes of children between the ages of 8–17 years with lens subluxations more than 7 clock hours underwent pars plana lensectomy-vitrectomy with implantation of the iris-claw IOL in the retropupillary position as a primary procedure. The best corrected visual acuity (BCVA), intraocular pressure (IOP), corneal endothelial count (EC) and the lens position using ultrasound biomicroscopy (UBM) were assessed pre- and postoperatively.
Postoperatively, all patients had an increase in the BCVA with a mean of 0.351 ± 0.154 log MAR units which was statistically significant as compared to the preoperative value of 0.771 ± 0.132 log MAR units (p = 0.003). The difference between the mean preoperative IOP (13.642 ± 2.437 mmHg) and the mean postoperative intraocular pressure at the end of 6 months (13.5 ± 2.244 mmHg) was not statistically significant (p = 0.671). The mean EC decreased by 0.99% from 2838.42 ± 474.76 cells/mm2 preoperatively to 2810 ± 461.24 cells/mm2 at the end of 6 months postoperatively (p = 0.117). The lens position was analyzed using UBM and was found to be parallel to the iris plane in all cases at the end of 6 months.
Our study shows that primary retropupillary iris-claw IOL implantation can be a safe and efficacious option for children with large (>7 clock hours) lens subluxations that is at least comparable to scleral-fixated PCIOLs.
