Comparison of clinical outcomes of deep anterior lamellar keratoplasty and excimer laser assisted anterior lamellar keratoplasty in keratoconus
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
Comparison of clinical outcomes of deep anterior lamellar keratoplasty and excimer laser assisted anterior lamellar keratoplasty in keratoconus
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
