Contrast and glare sensitivity after implantation of AcrySof and Human Optics 1CU intraocular lenses

PURPOSE: To evaluate contrast and glare sensitivity of a newly developed, potentially accommodative intraocular lens. METHODS: The clinical interventional prospective randomized study included 20 patients (23 eyes) undergoing standard phacoemulsification with clear cornea incision in topical anesthesia. In the study group (10 eyes), the 1CU Human Optics intraocular lens (optics diameter 5.5 mm) was implanted. The control group (13 eyes) received the monofocal AcrySof intraocular lens (optics diameter: 6.0 mm). Using a newly developed contrast measuring device, contrast and glare sensitivity were tested 4 weeks after surgery. RESULTS: The study group and control group did not vary significantly in contrast (p=0.38) or glare sensitivity (p=0.52). CONCLUSIONS: The results suggest that the newly developed 1CU Human Optics intraocular lens and the standard AcrySof intraocular lens do not vary significantly in glare and contrast sensitivity.
