AIM: To assess the results of a modified technique for scleral fixation of a posterior chamber intraocular lens (IOL) in eyes which had deficient of posterior capsular support.
METHODS: This retrospective study was comprised of ten patients with deficient posterior capsular support who underwent one haptic fixation of posterior chamber IOLs, between February 2010 and October 2011. IOL as implanted with one haptic supported on the capsular remnant and the other haptic drawn into the sulcus by anchoring suture without a knot. All patients were evaluated for pre and postoperative visual acuity, lens centration, intra and postoperative complications.
RESULTS: A knotless, one haptic fixation of posterior chamber IOLs has successfully been performed on ten eyes. All cases had inadequate capsular support (la a capsular tear ranged from 5 to 7 clock hours). The average age was 74.25 +/- 8.87y (SD). The average postoperative uncorrected visual acuity was 0.51 logMAR. Complications included hyphema in one eye, a mild inflammatory reaction in the anterior chamber in two eyes, and a transient rise in IOP in one eye. Neither IOL tilt nor dislocation was observed and there were no later complications.
CONCLUSION: In the presence of insufficient capsular support, a knotless, one haptic fixation of posterior chamber IOLs is a safe and viable option which reduces the operation time, and minimizes postoperative suture related complications.
