Comparison of the Postoperative Outcomes in Combined Vitrectomy with Sutured Scleral Intraocular Lens Fixation versus Sutureless Intrascleral Haptic Fixation

Purpose: The study aimed to compare the postoperative refraction outcomes between two techniques and evaluate the incidence of iris-optic capture in patients who underwent sutured scleral intraocular lens fixation (sutured SF IOL) and sutureless intrascleral haptic fixation (sutrueless SF IOL; Yamane technique). Methods Medical records of patients who underwent two types of SF IOL technique were retrospectively analyzed. The sutured SF IOL group included 24 eyes, whereas the sutureless SF IOL group included 41 eyes. The spherical equivalent (SE) difference (postoperative SE – target SE) was measured using an automatic refractive keratometer 2 months after the surgery. The occurrence of iris-optic capture was also confirmed during the 2-month follow-up after the surgery. Results In the sutured SF IOL group, the postoperative SE was − 1.00 ± 1.07, and subtracting the target SE from the postoperative SE obtained − 0.42 ± 0.69, which showed a myopic shift tendency. In the sutureless SF IOL group, the postoperative SE was − 0.34 ± 1.03, and subtracting the target SE from postoperative SE obtained 0.25 ± 0.71, showing a hyperopic shift tendency. Iris-optic capture was noted only in the sutured SF IOL group (4/24 eyes). Conclusions With the sutureless SF IOL technique, the setting of refraction is similar to the target refraction before surgery, and IOL-iris irritation is minimized, reducing complications such as iris-optic capture.
