Evaluation of Visual Outcomes and Complications Undergoing Penetrating Keratoplasty

Aims: To evaluate the visual outcomes and its complications in patients undergoing penetrating keratoplasty. Method: Patients selected for penetrating keratoplasty from out patient department. Local examination and systemic examination was done before enrolling the patient for the study. Result: Leucomtaous corneal opacity with unknown etiology was major indication of penetrating keratoplasty. Graft rejection was found to be in 4 (13.3%) out 30 patients.66.7% cases showed epithelial defect on post operative day 1 whereas at 6th month 90% had no epithelial defect and 10% developed corneal opacity. Moderate (6-10 mm/min on Schirmer test) dry eye condition was observed to be a complication with 46.7% involvement of total sample cases. Glaucoma was found to be a major complication. Conclusions: Visual acuity gradually improved from hand movement to 6/36 or better. Iritis and uveitis can occur post operatively but with proper management in it reduces. Eye drop heparin was advised to patients with corneal vascularization and was found to be effective in preventing the progression of vascularization.
