Intraocular lens malposition after sutureless intrascleral fixation of intraocular lens.

PURPOSE To introduce cases of intraocular lens (IOL) malposition after sutureless intrascleral fixation. METHODS We retrospectively analyzed the medical records of patients who underwent sutureless intrascleral fixation. Cases with postoperative IOL requiring reoperation were analyzed further. RESULTS Of the 48 eyes that underwent sutureless intrascleral fixation of their IOL, seven eyes had postoperative IOL malposition and underwent reoperation (14.6%). There was no difference in the clinical results between the intravitreal (33 eyes) and intracameral (15 eyes) techniques, but IOL malposition requiring reoperation was more frequent in the latter (two cases [6.1%] vs. five cases [33.3%], p=0.024). In the seven eyes that required reoperation, visual acuity before reoperation was 0.9±0.6 logMAR (20/159), while astigmatism was -4.8±3.2 diopters. The visual acuity and cylindrical error improved to 0.1±0.2 logMAR (20/25) and -2.4±2.3 diopters, respectively, at 6 months after the secondary operation. CONCLUSION In 14.6% of the patients who underwent sutureless intrascleral fixation of the IOL, IOL malposition developed and reoperation was performed. With the intravitreal technique, which uses a wider space than the intracameral technique, the frequency of postoperative IOL malposition could be reduced.
