Visual Quality, Patient Satisfaction, and Photic Phenomena With a Diffractive Intraocular Lens and Its New Evolved Materials Version.

Abstract

Purpose: To assess the visual quality, patient satisfaction, and photic phenomena 3 and 12 months after the implantation of two similar diffractive intraocular lenses (IOLs) manufactured with different materials.

Methods: This retrospective observational study included patients with the AcrySof PanOptix IOL or the Clareon Pan-Optix IOL (both Alcon Laboratories, Inc). Three and 12 months after the surgery, binocular contrast sensitivity under photopic conditions was measured. The presence of dysphotopsias and difficulties when driving in dim light conditions was also reported. Patient satisfaction was assessed through the Catquest 9-SF questionnaire and patients also reported the need for additional spectacles at different distances. Twelve months after the surgery, the presence of posterior capsule opacification and glistening was reported.

Results: The study included 59 patients. Contrast sensitivity was stable in both groups 12 months after the surgery, the proportion of patients that always perceived halos decreased approximately 15%, and difficulties when driving at night were minimized. Both groups showed high and similar rates of satisfaction with their vision and achieved spectacle independence rates greater than 85% at the two visits. The presence of posterior capsule opacification was similar for both groups, whereas 64% and 90% of the eyes were free of glistening in the AcrySof and Clareon groups, respectively.

Conclusions: Both diffractive IOLs offer consistent visual outcomes and high rates of patient satisfaction during the initial 12 months after surgery. The results also suggest that the novel material may better preserve the transparency of the IOL in the long term. [J Refract Surg. 2024;40(11):e877-e883.].
