Anterior Iris-Claw Lens Implantation with Single Paracentesis

Abstract

In this study, the technique and results of iris-claw intraocular lens (IOL) implantation with corneal incision and single paracentesis were presented. Eighteen eyes of 18 patients who underwent iris-claw implantation surgery with a single paracentesis were included in this prospective study. Iris-claw lens was grasped by its forceps and placed into the anterior chamber through superior corneal opening. While IOL was held by forceps, a blunt enclavation spatula was introduced through inferior paracentesis. Then the spatula was directed toward underneath of iris through pupil and toward sides where iris was entrapped into the claw by gentle push of iris through the slotted center of the lens haptics. Mean age of patients was 54.28 ± 25.21 years (7–76 years). Mean anterior chamber depth was 4.07 ± 0.32 mm and mean keratometric power was 43.01 ± 2.73 D. Preoperative BCVA was 20/63 or better in 8 (44.4%) patients. At the first postoperative month BCVA was 20/63 or better in 14 (77.8%) patients. Preoperative mean spherical refraction was +11.05 ± 2.62 D, preoperative astigmatism was 2.15 ± 0.85. Postoperative mean spherical refraction was −0.58 ± 0.25 D and mean astigmatism was −1.92 ± 0.67 D. The most frequent postoperative complication was mild corneal edema seen in three patients that resolved completely during the first week with medical treatment. Irisclaw IOL implantation can be performed easily with corneal incision and single paracentesis. Single paracentesis does not increase surgical time or cause inconvenience during the procedure.
