Comparison of the Visual Performance after Implantation of Three Aberration-correcting Aspherical Intraocular Lens.

Purpose: To compare the visual performance after implantation of three aberration-correcting aspherical intraocular lens (IOL).
Materials and Methods: Seventy-seven eyes of 77 cataract patients were divided into three groups: 26 eyes implanted with a non-constant aberration IOL (LUCIA 601P IOL, Zeiss Company, Germany); 26 eyes implanted with a spherical aberration -0.18μm IOL (CT ASPHINA 509M, Zeiss Company, Germany) and 27 eyes implanted with a spherical aberration -0.27μm IOL (AMO Tecnis ZCB00, Johnson & Johnson Surgical Vision, USA). Three months after operation, the distance visual acuity, wavefront aberrometry, contrast sensitivity, intraocular stray light, IOL decentration, and tilt were evaluated.
Results: Three months postoperatively, no statistically significant differences were found in uncorrected distance visual acuity and corrected distance visual acuity ( p ≥.83). The RMS for total ocular coma was statistically significantly lower in the Lucia group ( p =.03) and spherical aberration was statistically significantly lower in the Tecnis group ( p <.01). No statistically significant differences were observed among the three lenses in higher order aberration ( p =.85) and in contrast sensitivity under both photopic and mesopic lighting conditions ( p ≥.05). The intraocular stray light was statistically significantly better in the Lucia group ( p =.04). No statistically significant differences were observed with respect to IOL decentration ( p =.75) and tilt ( p =.89).
Conclusions: Cataract surgery with non-constant aberration IOL resulted in lower coma and better intraocular stray light than with the spherical aberration -0.18μm and -0.27μm IOLs despite equivalent postoperative levels of visual acuity and contrast sensitivity.
