Abstract Details

Purpose:

To present our experience and outcomes in the management of cases that suffered severe ocular trauma requiring keratoprosthesis.

Setting:

Sussex Eye Hospital. Brighton UK

Methods:

Retrospective case series of cases operated at the Sussex Eye Hospital. Brighton UK between 1995 and 2016.

Results:

A total of 14 patients underwent Kpro surgery; 13 had osteo-odonto-keratoprosthesis (OOKP) and one underwent Boston type 1 keratoprosthesis. The primary diagnose at referral was severe chemical injury in 7 cases (50%), severe thermal injury in 2 cases (36%) and dog bite in 2 cases (14%). 12 patients (86%) were male and 2 (14%) were female. Mean age was 43.6±12.08 (range: 24 to 61) and the pre-operative vision was counter fingers or worse in all patients. Kpro surgery were successful in 11 patients (76%) including the Boston type 1. 6 patients (42%) achieved BCVA > 6/60 and < 6/9 and five patients (36%) achieved 6/6 with follow up up to ten years. 3 patients (21%) had poor outcome due to severe complications: non repairable retina detachment, terminal glaucoma and endophthalmitis respectively. Pre-existing glaucoma was present in 39% of patients and was the most common comorbidity. In the OOKP group bone lamina resorption that required new OOKP lamina allograft occurred in only one case.

Conclusions:

Keratoprosthesis after severe ocular trauma en special OOKP which is the most enduring Kpro can successfully restore visual function if the patient has no posterior segment damage and complications are managed appropriately.
