Pars plana vitrectomy through the Boston Keratoprosthesis type 1

Characteristics and vitreoretinal management of retinal detachment in eyes with Boston keratoprosthesis

“…The authors have concluded that small-gauge vitrectomy can be effectively used for patients with permanent KPro. More recently, Harissi-Dagher et al 6 reported on the outcomes from the use of 20-gauge PPV (modified technique as described by Stanescu-Segall et al 16) in five cases. Retinal detachment was the primary indication in four cases and suprachoroidal haemorrhage from glaucoma tube overfiltration in one case.…”

Vitreoretinal aspects of permanent keratoprosthesis

“…73 Despite the utilization of modified vitreoretinal techniques for posterior segment complications, visual outcomes remain poor. 42,73 Earlier or prophylactic intervention may improve anatomic and visual outcomes in the setting of vitreoretinal pathology with KPro. Maintenance of a closed, firm eye during the procedure may be the most important factor in achieving a successful visual outcome.…”

“…42,55,73,74 Vitrectomy with a permanent KPro is safe and has no deleterious effects on the donor cornea/graft KPro device. Cohort studies report the incidence of vitrectomy after KPro placement to be around 7%.…”

“…2), vitreous biopsy, glaucoma shunt placement/revision, retroprosthetic membranectomy, retinal detachment, suprachoroidal hemorrhage drainage, endophthalmitis, epiretinal membrane removal, proliferative vitreoretinopathy, hypotony, and removal of vitreous opacities including vitreous hemorrhage. 42,55,73 Scleral buckling is an alternative or complementary procedure that may be performed at the time of vitrectomy in the setting of retinal detachment; 42 however, in KPro eyes with compromised scleral and anterior segment tissues may be of limited value. 73 Despite the utilization of modified vitreoretinal techniques for posterior segment complications, visual outcomes remain poor.…”

“…Cohort studies report the incidence of vitrectomy after KPro placement to be around 7%. 42 Retrobulbar anesthesia is typically used in the same manner as other vitrectomies. An open sky ( Fig.…”
