[Keratoplasty classification and primary disease spectrum analysis of 315 cases].

Objective: To identify the primary disease spectrum and trends of surgical procedure of keratoplasty patients. Methods: Retrospective case series study. To review all patients who underwent keratoplasty at Department of ophthalmology in Tongji Hospital from January 1, 2012 to December 31, 2015. The data collected included age, sex, birthplace, and primary corneal disease and associated surgical procedures. Then the data were compared with similar papers domestic and foreign. Results: A total of 315 keratoplasties were performed during this 4-year period. The average age of patients at time of surgery was (42.0± 1.8) years, range from 33 days to 89 years, 229 cases (72.7%) were from 18 to 65 years; male: female ratio was 2.06:1. Totally 289 cases (91.8%)came from Hubei province, 26 cases (8.2%) were from other provinces. The leading indications for corneal transplantation were keratitis in 125 cases (39.7%), followed by corneal scar in 71 cases (22.5%), keratoconus in 41 cases (13.0%), pseudophakic bullous keratopathy in 26 cases (8.3%), corneal dermoid in 18 cases (5.7%), corneal dystrophy and degeneration in 16 cases (5.1%), and others (including chemical injuries, thermal burns, post-traumatic corneal scar and corneal opacity) in 18 cases (5.7%). Of the 125 keratitis cases, 51 cases (40.8%) were associated with fungus, 43 cases (34.4%)were associated with virus, and 24 cases (19.2%)were associated with bacterial. In accordance with the classification of corneal transplant surgery, penetrating keratoplasty was performed in 212 cases (67.3% ), lamellar keratoplasty was completed in 87 cases (27.6% ), corneal endothelial transplantation was made in 16 patients (5.1%). Conclusions: Infectious keratitis was the leading indication for corneal transplantation followed by corneal scar, keratoconus and pseudophakic bullous keratopathy in Tongji hospital patients who underwent keratoplasty. And fungus was the first cause of infectious keratitis. Penetrating keratoplasty was still the main part of corneal transplantation.
