PURPOSE: To evaluate the safety and efficacy of a new multi-segmented refractive multifocal intraocular lens (IOL) after phacoemulsification and refractive lens exchange (RLE).
PATIENTS AND METHODS: In this prospective, multicenter clinical trial, 63 presbyopic subjects who had cataract or where RLE candidates were bilaterally implanted with the Precizon Presbyopia IOL (Ophtec BV, Groningen, the Netherlands) after phacoemulsification. The study was conducted at 6 clinical centers in Germany, the Netherlands, Belgium, Turkey and Spain. Subjects were evaluated at baseline and at 1 day, 1 week, 1 and 3 months postoperatively for monocular and binocular uncorrected (UDVA) and corrected distance visual acuity (CDVA), uncorrected (UIVA) and distance-corrected intermediate visual acuity (DCIVA), uncorrected (UNVA), corrected (CNVA) and distance-corrected near visual acuity (DCNVA), contrast sensitivity and quality of vision.
RESULTS: Three months postoperatively, binocular UDVA and CDVA of ≥20/40 was achieved in 98.4% (60/61) and 100%, respectively. Binocular UIVA and DCIVA of ≥20/40 was achieved in 96.7% (59/61) and 93.4% (57/61) respectively. Binocular UNVA, CNVA and DCNVA of ≥20/40 was achieved in 93.4% (57/61), 98.4% (60/61) and 95% (57/60) subjects, respectively. Complete spectacle independence was achieved in 80% (49/61) patients; 93% of patients reported that they were quite or very satisfied with the outcomes of the procedure.
CONCLUSION: Precizon Presbyopia IOL implantation is a safe and effective method to provide good visual acuity at all distances in presbyopic and cataract patients.
