Comparison of clinical outcomes of deep anterior lamellar keratoplasty and excimer laser assisted anterior lamellar keratoplasty in keratoconus
Journal Title: International Journal of Ophthalmology - Year 2019, Vol 12, Issue 4
Abstract
"AIM: To compare and evaluate the clinical outcomes of deep anterior lamellar keratoplasty (DALK) and excimer laser assisted anterior lamellar keratoplasty (ELLK) in eyes with keratoconus. METHODS: In this study, 57 eyes of 56 patients operated between 2013 to 2017 were included. Thirty-one eyes underwent big-bubble DALK and twenty-six eyes underwent ELLK. Preoperative and at control visits complete ophthalmic examination was performed. RESULTS: The mean patient age at the time of DALK surgery was 27y and mean follow-up period was 21±5.4mo. The mean patient age at the time of ELLK surgery was 27y and mean follow-up period was 40±18mo. Mean best spectacle corrected visual acuity (BSCVA) at postoperative period was significantly higher for DALK group (0.66±0.11) versus ELLK group (0.4±0.2) (P<0.05). Descemet’s membrane microperforation was occurred in 7 patients in DALK group versus in 1 patient in ELLK group. In 4 eyes, interface irregularity was developed in ELLK group. None of the patients in follow-up had graft rejection in both groups. CONCLUSION: In ELLK group, complication rate is lower, the surgical technique is simpler, faster and safer and also ELLK requires less experience with respect to DALK. Further, DALK can be performed unless satisfactory visual acuity is achieved after ELLK."
