[Outcomes of keratoprosthesis at Labbafinejad medical center]

ABSTRACT

To evaluate the results of keratoprosthesis [KPS] at Labbafinejad Medical Center. In this case-series 29 eyes of 27 patients who underwent KPS between 1995-2002 were evaluated for results and complications. Patients included 22 male and five female subjects. Diagnoses included chemical burn [17 cases], Stevens-Johnson syndrome [three cases], ocular cicatricial pemphigoid [seven cases], corneal retransplantation [one case] and old corneal scar [one case]. Preoperative visual acuity was hand motion or light perception [no light perception, hand motion, or light perception in the fellow eyes],. Prostheses were Girard in 20 cases, tibiakeratoprosthesis in 3 cases, and Dohlman type 1, Dohlman type 2 and Pintucci, each in two cases. Postoperative visual acuity improved in 21 patients [72.4%] of which 66.7% experienced major complications including bacterial endophthalmitis [42.9%], retinal detachment [28.6%], uncontrolled glaucoma [21.4%], and spontaneous extrusion [7.1%]. Although KPS is hopeful in the short term with acceptable initial results, the long-term complication rate is high and the prognosis is poor. So it is better that KPS be preceded with safer procedures such as keratolimbal graft especially in young patients
