Abstract Details


To analyse the effectiveness of Mydriasert implant for pre-operative dilatation in a real world clinical setting


Birmingham and Midland Eye Centre, UK


Prospective un-blinded trial for cataract surgery in a tertiary ophthalmology centre. Initial sampling for patients dilated with drop regime folllowed by Mydriasert. Patient demographic, systemic and ocular co-morbidities, complication rates, and requirement of intra-operative dilators were collected via electronic medical records. Patients and nursing staff reported outcomes were measured. Cost-analysis was also conducted.


62 patients dilated with drops and 67 with Mydriasert. Large pupil grading higher with Mydriasert (96%) than drops (49%). Intraoperative dilators required in 7% and 23% of Mydriasert and drops group respectively. Complication rate 4% and 8% in Mydriasert and drops group respectively. Reduced nursing time and 85% nursing preference with Mydriasert. More patients grading happiness as "high" with Mydriasert (96% vs 27%). 32% of second eye patients rating Mydriasert better than drops and none preferring drops. Average cost for dilation (including intraoperative dilators) lower in Mydriasert group (£7.07 vs £9.91).


Mydriasert is clinically advantageous and cost-effective for pre-operative dilation compared to drops.
