Deep Anterior lamellar Keratoplasty (DALK) has become the corneal transplantation technique of choice for corneal diseases that spare the corneal endothelium. The major indications include keratoconus, stromal corneal dystrophies, corneal scars that spare the Descemet membrane (DM) and recalcitrant infectious keratitis. Unlike the old technique of penetrating/full thickness corneal transplantat...

OBJECTIVES To compare clinical outcomes of cases who underwent deep anterior lamellar keratoplasty (DALK) and cases who were converted to penetrating keratoplasty (PKP) from DALK surgery. MATERIALS AND METHODS The records of 54 patients for whom DALK surgery was planned and were operated for different diagnoses between March 2013 and June 2015 were retrospectively analyzed. Patients were divi...

PURPOSE To evaluate corneal biomechanics with the Ocular Response Analyzer (ORA; Reichert Ophthalmic Instruments, Depew, NY) after penetrating keratoplasty (PK) and deep anterior lamellar keratoplasty (DALK). SUBJECTS AND METHODS Sixty-three eyes of 63 patients were included in this prospective comparative study. Patients were divided into 3 groups: the first included 21 eyes of normal subjec...

PURPOSE To present a case of Maroteaux-Lamy syndrome (MLS), which underwent deep anterior lamellar keratoplasty (DALK) for visual rehabilitation. METHODS A 15-year-old girl with MLS was admitted with severe corneal opacity. We performed DALK on her left eye for visual rehabilitation. Big-bubble technique was used to perform lamellar separation. RESULTS Corneal graft was clear 24 months afte...

The purpose of the study is to report the visual, refractive, and wound healing pattern outcomes of femtosecond assisted deep anterior lamellar keratoplasty (DALK) compared to the conventional manual technique. DALK was performed on 50 eyes of 47 advanced keratoconus patients. The patients were divided into two groups, 25 eyes each, depending on whether femtosecond assisted or manual DALK techn...

Deep anterior lamellar keratoplasty (DALK) is an emerging surgical technique for the restoration of corneal clarity and vision acuity. The big-bubble technique in DALK surgery is the most essential procedure that includes the air injection through a thin syringe needle to separate the dysfunctional region of the cornea. Even though DALK is a well-known transplant method, it is still challenged ...

PURPOSE To compare the visual quality of patients with keratoconus who underwent penetrating keratoplasty (PKP) or deep anterior lamellar keratoplasty (DALK) with fluid dissection. DESIGN Cross-sectional, observational study. METHODS Twelve eyes that underwent PKP (PKP group) were compared to 24 eyes that underwent DALK (DALK group) after complete removal of sutures and stability of refract...

PURPOSE To report the clinical outcomes of deep anterior lamellar keratoplasty (DALK) when sterile gamma-irradiated acellular corneal tissues (VisionGraft) are used in combination with amniotic membrane transplantation (AMT) for intractable ocular surface diseases. METHODS The medical records of fifteen patients who had DALK with AMT were retrospectively reviewed. Indications for surgery incl...

BACKGROUND This study describes the in vivo confocal microscopy findings in two patients who had deep anterior lamellar keratoplasty (DALK) following Descemet's stripping automated endothelial keratoplasty (DSAEK). METHODS The study reviewed the cases of two patients who first underwent DSAEK followed by DALK when their vision failed to improve due to residual stromal scarring. In the first c...

PURPOSE A single-center, cross-sectional study was designed to assess and compare objective and subjective quality of vision of patients intervened with penetrating keratoplasty (PK), deep anterior lamellar keratoplasty (DALK) and Descemet membrane endothelial keratoplasty (DMEK). METHODS Forty-six patients previously intervened with PK (22 eyes), DALK (7 eyes) and DMEK (17 eyes) were recruit...
