PURPOSE
To evaluate the stability and optical performance of the newly developed single-piece aspheric intraocular lens (IOL) by comparing the clinical outcome of the aspheric IOL with the new optic profile design (HOYA iSert, HOYA iMics) and the aspheric IOL (Akreos MI60), which has been proven effective and safe. METHODS: iSert, iMics, and MI60 were inserted into 55 eyes, 60 eyes, and 50 eyes, respectively, after microincision phacoemulsification cataract surgery. Best corrected visual acuity (BCVA), refraction in spherical equivalent, anterior chamber depth (ACD), total higher order aberration (HOA), contrast sensitivity, and surgically induced astigmatism (SIA) were measured and each IOL was evaluated on the functional stability, anterior-posterior stability, centration in the capsular bag, and quality of vision. RESULTS: No statistical differences in preoperative and postoperative BCVA among the 3 IOL groups were observed, however, MI60 showed significant myopic shift postoperatively. Anterior-posterior stability assessed with postoperative change in refractive error and ACD was slightly lower in the MI60 group. In terms of vision quality, while total aberration, total HOA, coma aberration, and contrast sensitivity for the 3 IOLs were not different significantly, spherical aberration of the MI60 group was higher than the other groups at 6 months postoperative. SIA was significantly increased in eyes implanted with iSert than in eyes with iMics or MI60 at 1 month postoperatively, however, the differences were no longer evident after 3 months postoperatively. CONCLUSIONS: The new aspheric IOLs, iSert and iMics, showed good stability and visual outcome equal to MI60 at the 6-month postoperative follow-up. |
