Etiology and failure analysis of anterior lamellar keratoplasty
Journal Title: International Journal of Ophthalmology - Year 2018, Vol 11, Issue 5
Abstract
"AIM: To analyze indications and reasons for failure of anterior lamellar keratoplasty (ALK). METHODS: The clinical records were retrospectively reviewed. Main outcome measures included indications for ALK and reasons for failure of ALK. RESULTS: A total of 434 patients (462 eyes) were treated with ALK at Qingdao Eye Hospital, Shandong Eye Institute from June 1, 2009 to May 31, 2016. The main indications were infectious keratitis (33.3%), keratoconus (23.6%), corneal dystrophy and degeneration (9.8%), Mooren’s ulcer (8.4%), corneal neoplasm (7.8%), viral keratitis (6.5%) and regrafting (3.7%). Fungal keratitis accounted for 73.4% in the infectious keratitis cases. ALKs were failed in 36 patients, with the major causes being recurrence of primary diseases (63.9%). The leading causes of graft failure was Mooren’s ulcer (36.1%), followed by infectious keratitis (30.6%). Recurrence of fungal keratitis accounted for 81.8% in the failed cases after ALK for infectious keratitis cases. CONCLUSION: Infectious keratitis and keratoconus are the main indications for ALK, of which fungal keratitis was the major cause of corneal infections. Recurrence of primary disease is the main reason of graft failure after ALK, in which the main primary diseases associated with graft failure are Mooren’s ulcer and fungal keratitis."
