A new technique of needle-guided retropupillary fixation of iris-claw intraocular lens

Abstract

The authors developed a new surgical technique of retropupillary implantation of an iris-claw intraocular lens (RP-ICIOL). RP-ICIOL is an alternative surgical option to the scleral-fixation technique for the treatment of aphakia without capsular support. Several studies have shown that RP-ICIOL is efficient and safe. However, although it is easier to perform than scleral fixation, it presents some critical issues related to the enclavation procedure. The success of the correct enclavation without excessive surgical manipulations, with subsequent pigment dispersion and without pupil distortion, is highly related to the surgical skills of the individual surgeon. The new technique proposed by the authors consists of using a guide needle to facilitate the enclavation, and to make this surgical procedure standard. The new technique was performed in 26 patients affected by aphakia without capsular support with encouraging functional and anatomical results.
