Vyas A (2015) Incidence of Dysphotopsia in Patients Implanted with the C-flex^® Intraocular Lens with 360° Enhanced Edge: A Questionnaire-Based Study

Background: To evaluate the incidence of dysphotopsia associated with the hydrophilic C-flex® monofocal intraocular lens (IOL) with 360° enhanced edge in patients undergoing cataract surgery. Design: Single-centre (hospital), consecutive case study Participants: Forty patients (average age, 76.6 years [range, 62-85 years]) without co-morbidity who underwent phacoemulsification surgery. Methods: All patients were implanted with the hydrophilic C-flex® (570C) monofocal IOL (Rayner Intraocular Lenses Limited, Hove, UK) through a 2.8 mm incision. The C-flex® has 360° enhanced edge designed to reduce the centripetal migration of the lens epithelial cells. Patients underwent a slit lamp examination 1 day, 1 week, 1 month and 3 months postoperative, and were asked to complete a questionnaire describing any visual symptoms at their one-month or three-month visit. Main outcome measures: Incidence of dysphotopsia and patient satisfaction. Results: Eighteen (45%) patients reported no ocular symptoms at their 1 or 3 month postoperative visit, and none of the 22 (55%) patients who did report visual disturbances found their symptoms debilitating. The most common post-operative visual phenomenon was glare, reported by 23% of patients; unwanted imagery was noted in 17% (7) patients. Almost all patients (98%) patients stated that they were either very satisfied or satisfied with their visual outcomes following C-flex® lens implantation. Conclusion: The C-flex® IOL was associated with a low incidence of dysphotopsia and a high degree of satisfaction with postoperative visual outcomes. Unwanted imagery, which could be related to the lens implant, occurred in only one out of forty patients.
