Surface light scattering from one-piece hydrophobic acrylic intraocular lenses with hydroxyethyl methacrylate: contralateral observation for 7 years.

Purpose To quantitatively and intraindividually compare surface light scattering for 7 years after implantation of Clareon and AcrySof intraocular lenses (IOLs). Setting Miyata Eye Hospital, Miyazaki, Japan DESIGN:: Retrospective comparative case series. Methods Clinical records of eyes that had contralateral implantation of SN60WF and SY60WF IOLs were reviewed. Light scattering on the anterior surface of IOLs, corrected distance visual acuity (CDVA), and mesopic and photopic contrast sensitivities were examined at 1, 3, and 7 years postoperatively, and they were intraindividually compared. Results Thirty-four, nineteen, and sixteen patients who respectively visited 1, 3, and 7 years postoperatively. Surface light scattering in eyes with SY60WF was significantly reduced, and the rate of increase was 2.74 CCT per year. Although there were prominent increases in eyes with SN60WF, no difference was found in their CDVA and contrast sensitivities. Conclusions In eyes with Clareon IOLs, the development of surface light scattering was suppressed up to 7 years. The increase rate demonstrated that the visual acuity would be least deteriorated up to 12 years postoperatively, while the influence of straylight induced should be investigated.
