Comparisons of Clinical Results after Implantation of Three Aspheric Intraocular Lenses

ABSTRACT

PURPOSE: To compare the clinical 3 months postoperative results of three different 1-piece aspheric intraocular lenses (IOLs): AcrySof IQ SN60WF (Alcon Laboratories, INC, Fort Worth, TX), TECNIS 1-piece ZCB00 (AMO Inc., Santa Ana, CA) and the newly developed enVista MX60 (Bausch & Lomb, Rochester, NY). METHODS: In a total of 62 eyes, 1 of the 3 1-piece aspheric IOLs, AcrySof IQ SN60WF, TECNIS 1-piece ZCB00 or enVista MX60 was implanted after cataract extraction. Best corrected visual acuity (BCVA), uncorrected visual acuity (UCVA), and spherical equivalent were assessed 3 months postoperatively. Total spherical aberration, high order aberration, and modulation transfer function were analyzed. RESULTS: There were no significant differences of UCVA, BCVA, the accuracy of postoperative refractive power, and modulation transfer function among the 3 IOLs. Higher order aberrations of the entire eye and internal optics showed almost no significant differences. CONCLUSIONS: The newly developed IOL, enVista MX60, showed equivalent clinical outcomes as both AcrySof IQ SN60WF and TECNIS 1-piece ZCB00.
