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. Posterior capsulotomy rate and dysphotopsias following implantation of Hoya iSert 250 monofocal intraocular lens: 24 month study.
