Clinical Results of Deep Anterior Lamellar Keratoplasty in Treatment of Advanced Keratoconus; Big Bubble Technique

Material and Methods: Seventeen eyes of seventeen patients with advanced keratoconus who underwent DALK using Anwar's big bubble technique with1 year postoperative follow up were included in study. Uncorrected and corrected distant visual acuities (UDVA, CDVA, snellen acuity converted to logMAR notation), spherical equivalent SE (Diopters D)], refractive astigmatism [(Ast, D)], slit lamp biomicroscopy and endothelial cell count (ECD) were recorded at baseline and at 1, 6 and 12 months postoperatively. Intra and postoperative complications were documented.
