Abstract Details


To evaluate dysphotopsias, patient satisfaction and posterior capsulotomy rate in patients undergoing micro-incision cataract surgery and implantation of Hoya iSert 250 monofocal intraocular lens.


Retrospective, questionnaire-based study at Maidstone District General Hospital, UK.


Patients were implanted with the hydrophobic acrylic IOL Hoya iSert 250 monofocal intraocular lens through a 2.2mm clear corneal/ limbal incision. The IOL has a proven Aspheric Balanced Curve design that provides patients with sharp images. Its square edge helps to minimize posterior capsular opacification. Patients were asked to respond to a telephone questionnaire describing any visual symptoms and their satisfaction. The number requiring posterior capsulotomy was collected. Main outcome measures included dysphotopsias, patient satisfaction and posterior capsulotomy rate.


106 patients had the Hoya iSert 250 lenses implanted over a seven month period in 2014. 88 patients were contacted at 18 months post- operatively. 18 had passed away or were not contactable. 61 patients completed the survey. 15 patients (24.5%) reported transient positive dysphotopsia (glare, light sensitivity, haloes, arcs and flashes of light). One patient (1.6%) reported negative dysphotopsia (crescent effect). 95% were either very satisfied or satisfied with their vision (59% 'very satisfied' and 36% 'satisfied'). 3 patients had a YAG laser capsulotomy within 18 months post-operatively (4.9%) and 3 patients were awaiting laser treatment (3.2%).


The Hoya iSert 250 monofocal intraocular lens had a low dysphotopsia and posterior capsulotomy rate with the majority of patients being 'Very Satisfied' with their vision at 18 months.
