Abstract

|
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.
