Early results of penetrating keratoplasty following limbal stem cell transplantation. Indian Journal of Ophthalmology. 2005 Mar; 53(1): 31-5http://imsear.searo.who.int/handle/123456789/70036PURPOSE: To describe the early results of penetrating keratoplasty (PKP) in patients who had earlier received limbal transplantation (LT). METHODS: Prospective, non-comparative interventional case series comprising of four patients with limbal stem cell deficiency (LSCD) due to chemical injury (Cases 1, 2, 4) and xeroderma pigmentosum (Case 3). Cadaveric kerato-limbal allografts or living-related conjunctival-limbal allografts were done in four eyes followed by PKP for visual rehabilitation 3-4.5 months later. The following details were noted: demographics, primary aetiology, type of limbal transplant (cadaveric or living-related), immunosuppression, vision and ocular surface stability before and after LT and PKP, surgical complications and outcome of PKP. RESULTS: Three eyes received living-related conjunctival-limbal allotransplantation and one received cadaveric kerato-limbal allograft. Duration of follow up after PKP ranged from 4 to 11 months. Visual acuity improved in the early postoperative period in all patients but reduced in 2 due to endothelial rejection and after trans-scleral cyclophotocoagulation for medically uncontrolled glaucoma. The ocular surface remained stable in all patients. All patients were started on immunosuppression on the first postoperative day. This was continued till the last follow-up visit. Post-PKP complications were punctate epithelial keratopathy, corneal allograft rejection and secondary glaucoma (one patient each). CONCLUSION: Satisfactory visual rehabilitation is possible after PKP following LT without compromising ocular surface stability. However, a prolonged and close follow-up is warranted to avert complications.engAdultBurns, Chemical --surgeryCadaverConjunctiva --transplantationEye Burns --chemically inducedFemaleHumansKeratoplasty, PenetratingLimbus Corneae --surgeryLiving DonorsMaleProspective StudiesStem Cell TransplantationTransplantation, HomologousTreatment OutcomeXeroderma Pigmentosum --surgeryCase Reports
