Clinical Outcomes of Superflex？？ Large Optic Intraocular Lens

Purpose: To evaluate the clinical outcomes after in the bag insertion of Superflex？？ intraocular lens (IOL) which has 0.25 mm bigger optic diameter than the conventional IOL. Methods: Retrospective chart review was performed for 15 eyes of 13 patients who had undergone phacoemulsification with in the capsular bag insertion of Superflex？？ IOL (experimental group) and for 28 eyes of 25 patients with in the bag insertion of Akreos？？ (control group). Best-corrected visual acuity (BCVA), manifest refraction, refractive error (RE; [postoperative spherical equivalent]–[preoperative target refraction]), corneal topography, higher-order aberration and contrast sensitivity were measured preoperatively and at 1 week, 1 month and 3 months postoperatively. Their changes after surgery were compared between both groups. Results: At 3 months after the surgery, RE was 0.22 ± 0.39 D in the experimental group and -0.17 ± 0.58 D in the control group, showing more hyperopic RE in the experimental group than the control group (p=0.007). BCVA, spherical equivalent, higher-order aberration, contrast sensitivity, and anterior chamber depth had no significant difference between two groups at 1 week, 1 month, and 3 months after the surgery. Conclusions: Superflex？？ IOL showed no significant difference in the clinical outcomes compared with Akreos？？ IOL until 3 months after the surgery. However, the target refraction of Superflex？？ IOL should be considered more myopic, since its postoperative refraction would be hyperopic.
