Abstract Details

Purpose:

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.

Setting:

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

Methods:

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.

Results:

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%).

Conclusions:

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.
