Comparison of Six-Month Outcomes in Eyes with Two Hydrophilic Aspheric Intraocular Lenses after Cataract Surgery

Purpose: To compare the six-month clinical outcomes of Tek-Lens II model 872 (Tekia, Inc.) and Akreos MI-60 (Bausch & Lomb, Inc.) hydrophilic aspheric intraocular lenses (IOLs) implanted in-the-bag. Methods: After phacoemulsification was performed by a single surgeon (JY Kim), two different hydrophilic aspheric IOLs were implanted: the Tek-Lens II IOL in 57 eyes and the MI60 IOL in 49 eyes. The best corrected visual acuity (BCVA), refractive error (RE), total high-order aberration (HOA), anterior chamber depth (ACD), and contrast sensitivity (CS) were measured preoperatively and one, three, and six months postoperatively. All parameters were analyzed using the independent t-test to compare the two IOL groups. Results: There was no significant difference in the BCVA, RE, or HOA between the two groups at any of the follow-up visits. Three months postoperatively, the ACD of the TEK-Lens II group as measured by corneal topography was significantly shallower than that of the MI60 group (3.67 ± 0.52 mm vs. 4.10 ± 0.40 mm; p = 0.008), and most of the photopic CS in the Tek-Lens II group was significantly higher than that in the MI60 group (all p < 0.05). Conclusions: The Tek-Lens II IOL showed comparable clinical outcomes with a proven hydrophilic aspheric IOL for the postoperative six months. J Korean Ophthalmol Soc 2012;53(6):767-774
