Posterior Capsulotomy Rate And Dysphotopsias Following Implantation Of Hoya iSert 250 Monofocal Intraocular Lens: 24 Month Study

Purpose: to evaluate dysphotopsias, patient satisfaction and posterior capsulotomy rate in patients undergoing phacoemulsification and implantation with Hoya iSert 250 monofocal intraocular lens (IOL). Design: retrospective cohort study. Setting- Teaching unit at a District General Hospital, UK. Methods: patients were implanted with the hydrophobic acrylic Hoya iSert 250 monofocal IOL through a 2.2mm clear corneal/ limbal incision. For dysphotopsia data, patients responded to a telephone questionnaire describing any visual symptoms and their satisfaction. Nd:YAG laser capsulotomy data were collected retrospectively from electronic medical records, paper notes and laser records. Eyes from patients (mean age 73.6 range 64-93 years) undergoing cataract surgery with implantation of Hoya iSert 250 IOL during the period January 1, 2014 and July 31, 2014, and 2-year follow-up were analysed. Main outcome measures: dysphotopsia rate, patient satisfaction and posterior capsulotomy rate. Results: 106 patients had the Hoya iSert 250 lenses implanted over a seven month period in 2014. 88 patients were contacted at 24 months post- operatively. 18 had passed away or were not contactable. 61 patients completed the survey. 15 patients (24.5%) reported transient positive dysphotopsias. One patient (1.6%) reported negative dysphotopsia. 95% were either very satisfied or satisfied with their vision (59% 'very satisfied' and 36% 'satisfied'). 3 patients (4.9%) had a YAG laser capsulotomy within 24 months post-operatively. Conclusions: the Hoya iSert 250 monofocal IOL was associated with low dysphotopsia and posterior capsulotomy rates with the majority of patients being 'Very Satisfied' with their vision at 24 months.
