Evaluation Of Cataract Treatment Results Using Phacoemulsification Surgery Method With A Standard Monofocal Lens Implant In One Eye And An Enhanced Monofocal Iol In The Other Eye

To investigate clinical outcomes obtained from subjects implanted with a standard monofocal lens implant (RayOne Spheric RAO100C, Rayner) in one eye and an enhanced monofocal IOL, RayOne EMV (RAO200E, Rayner) in the other eye with an emmetropic target in both eyes.

This retrospective data evaluation includes a total of 14 patients who underwent cataract surgery with implantation of a standard monofocal lens implant in one eye and an enhanced monofocal IOL, the RayOne EMV, in the other eye. Patients with no serious ocular conditions were selected. Data were available at 2 weeks and 3 months postoperatively. The following parameters have been evaluated: postoperative refraction, monocular and binocular uncorrected distance visual acuity (UDVA), monocular and binocular uncorrected intermediate visual acuity (UIVA) and monocular and binocular uncorrected near visual acuity (UNVA).

Interim results show that monocular UDVA improved in all examined patients from 0.72±0.38 preoperatively to 0.00±0.00 logMAR postoperative (after 3 months). Post-op, monocular UIVA in the eye with EMV was 0.65±0.09 after 3 weeks and 0.57±0.10 logMAR after 3 months, whereas the UIVA in the eye with a monofocal lens 0.67±0.08 logMAR after 3 months. Post-op, monocular UNVA in the eye with an the EMV was 0.67±0.11 after 3 weeks and 0.60±0.09 logMAR after 3 months respectively, whereas the UNVA in the eye with a monofocal lens implant was 0.67±0.08 logMAR after 3 months. Results show improvement in binocular UDVA to 0.00±0.00, UIVA to 0.45±0.05 and UNVA to 0.43±0.05 logMAR compared to monocular vision 3 months after phacoemulsification.

Outcomes of our study show that patients with RayOne EMV implanted in one eye and a standard monofocal lens implanted in the second eye significantly improve binocular UDVA, UIVA and UNVA. With respect to the emmetropic approach, the mean postoperative spherical equivalent was under ±1D. Vast majority of the patients needed no spectacles for distance and everyday near activities. No serious intra- or postoperative complications were noted throughout the study. In addition, patients did not report dysphotopsia and contrast or color differences between the eyes. Implantation of RayOne EMV in patients who have already undergone cataract surgery with monofocal lens implantation in the first eye improves UIVA and UNVA to a better degree.
