PURPOSE
We compared the clinical results after implantation of the newly-developed aspheric intraocular lens iSert 250 NC60 (Hoya Corporation Ltd., Tokyo, Japan) with 2 other types of widely used intraocular lenses, AcrySof IQ SN60WF (Alcon Laboratories, INC., Fort Worth, TX, USA) and TECNIS 1-piece ZCB00 (AMO Inc., Santa Ana, CA, USA). METHODS: Seventy cataract eyes were implanted with 1 of 3 aspheric intraocular lenses (Hoya iSert 250 NC60, TECNIS 1-piece ZCB00 or AcrySof IQ SN60WF) by the same surgeon. Uncorrected vision, best corrected vision, spherical equivalent, higher order aberrations, and modulation transfer function were measured 1 and 3 months after the cataract surgery. RESULTS: Uncorrected vision and best corrected vision were not significantly different among the 3 groups; however, eyes implanted with iSert250 NC60 showed more hyperopic-shifted postoperative spherical equivalents than expected compared to the other 2 groups. Total ocular aberrations and internal optics aberrations were similar among the 3 groups while the root mean square of the corneal aberrations showed differences. Eyes implanted with iSert 250 NC60 showed superior results in modulation transfer function compared with the other 2 groups in a majority of spatial frequencies 3 months postoperatively. CONCLUSIONS: The newly developed aspheric intraocular lens iSert 250 NC60 showed clinically equal results compared with 2 other verified intraocular lenses AcrySof IQ SN60WF and TECNIS 1-piece ZCB00 in vision, higher-order aberrations, and modulation transfer functions. |
