Retrospective data collection

The preoperative details which were noted included demographics, primary etiology, impression cytology reports, any previous ocular surgery, visual acuity at presentation, extent of LSCD, any coexistent lid anomalies or presence of symblepharon, intraocular pressure, and the interval duration between the various procedures. The follow-up parameters noted included visual acuity (in logMAR scale) after SLET and DALK and ocular surface stability (defined as ocular surface without recurrent surface epithelial morbidity and hyperemia) after SLET and outcomes of DALK (visual acuity and postoperative complications).
