Retinal Detachment Prevention In Opaque-Oornea Eyes Receiving A Permanent Keratoprosthesis.

Placement of a permanent keratoprosthesis (KPro), as a solution to otherwise untreatable corneal blindness, is becoming increasingly commonplace.1,2 But approximately 20% of KPro eyes suffer either rhegmatogenous, tractional or combined retinal detachment within seven years postoperatively.2 The dominant KPro model (Boston type 1 KPro)3 provides only a 3mm diameter optical stem, so that the retinal periphery remains largely obscured to clinical examination postoperatively. Partially as a consequence, repair of retinal detachment in KPro eyes is successful in less than 50% of cases, with most such eyes losing even ambulatory vision.4 This can be especially important because the fellow eye of most KPro patients, if it is even present, is also severely diseased.
