Abstract

: To assess the long-term outcomes of combined penetrating keratoplasty (PKP) and pars plana vitrectomy (PPV). : A retrospective review of eyes that underwent combined surgery followed for 12 months or longer. Demographic data, indications for surgery, and pre-/post-surgical eye examinations were retrieved. : Thirteen consecutive eyes (13 patients) were enrolled. The mean age was 51.5 ± 20.5 years, and the mean follow-up time was 67 ± 36.9 months. All cases had severe corneal opacity. Indications for surgery included retinal detachment (76.9%), dropped lens (7.7%), dropped intraocular lens (7.7%), and endophthalmitis with corneal abscess (7.7%). Visual acuity improved in 46.1% of the cases, though in most cases visual acuity remained low, and decreased in 23% of the cases. In 23% of the cases (3 eyes), ambulatory vision was achieved for more than 12 months and in 15.4% for three years. Silicone oil tamponade was used in all cases of retinal detachment (10 eyes). Of these eyes, at the final follow-up, four eyes were attached, two eyes were partially attached, and corneal opacity prevented retinal visualization in three eyes. One eye was eviscerated and one eye developed phthisis. Postoperatively, 61.5% of the cases underwent repeated PKP for graft decompensation. At the final visit, graft failure was observed in 75% of the cases. : The long-term follow-up of eyes that underwent combined PKP and PPV supports this technique in complex cases for eye and vision preservation. The main problem after combined surgery is the long-term survival of the corneal graft which may require repeated PKP surgeries. With this approach, in 23% of the cases, ambulatory vision was maintained for more than 12 months.
