Abstract Details


To evaluate the incidence of dysphotopsia associated with the hydrophilic C-flex® monofocal IOL in patients undergoing cataract surgery


Scarborough District General Hospital, York Teaching Hospital, United Kingdom


This single-centre,consecutive patient study included 40 patients without co-morbidity (average age, 76.6 years) who underwent phacoemulsification surgery. 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 degree enhanced edge around the optic as well as optic-haptic junctions to reduce centripetal migration of 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.


Eighteen (45%) patients reported no ocular symptoms at their one or three 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.


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.
