INTRAOCULAR LENS MALPOSITION AFTER SUTURELESS INTRASCLERAL FIXATION OF INTRAOCULAR LENS

To introduce cases of intraocular lens (IOL) malposition after sutureless intrascleral fixation.

We retrospectively analyzed the medical records of patients who underwent sutureless intrascleral fixation. Cases with postoperative IOL requiring reoperation were analyzed further.

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 (2 cases [6.1%] vs. 5 cases [33.3%], P = 0.024). In the 7 eyes that required reoperation, the visual acuity before reoperation was 0.9 ± 0.6 logMAR (20/159), whereas 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.

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.
