OBJECTIVES Study aims to evaluate the indications and surgical techniques for corneal transplantation and to report changes in trends for preferred keratoplasty surgical techniques. METHODS Clinical records of 815 consecutive corneal transplantations between January 1, 2004 and December 31, 2014 in Haydarpasa Numune Training and Research Hospital Eye Clinic were analyzed and classified into s...

AIM: To investigate whether the two-step strategy [conjunctival flap covering surgery (CFCS) combined with secondary deep anterior lamellar keratoplasty (DALK)] is effective for patients high-risk fungal keratitis (FK). METHODS: In this noncomparative, retrospective case series, 10 subjects (6 males, 4 females) a mean age of 56.5±7.1 (range 47-72)y FK undergone were included. Reported outcome m...

purpose: to determine the dissection level during deep lamellar keratoplasty (dalk) using the big-bubble technique by light microscopy (lm) and transmission electron microscopy (tem). methods: descemet’s membrane (dm) and stromal tissue of 4 keratoconic eyes were removed because of inadvertent intraoperative dm perforation during dalk which was converted to penetrating keratoplasty. these speci...

METHODS: Design: Retrospective interventional case series. Study population: 21 eyes from 21 patients who underwent visco-bubble technique for DALK, which involves the injection of ophthalmic viscosurgical devices (OVDs) into the deep stroma to form a visco-bubble to separate Descemet ́s membrane from the posterior stroma. Surgeries were performed between May 2010 and January 2013. Main outcome ...

deep anterior lamellar keratoplasty (dalk) has recently been introduced as an alternative procedure to penetrating keratoplasty (pk) for corneal pathologies not affecting the corneal endothelium. dalk does not rely on donor endothelium and requires less rigid criteria for donor corneal tissue quality. therefore, dalk makes it possible to use donor corneas deemed unsuitable for pk. furthermore, ...

purpose: to evaluate visual outcomes after deep anterior lamellar keratoplasty (dalk) in patients with keratoconus. methods: in this interventional case series, patients with moderate to advanced keratoconus underwent dalk. inclusion criteria consisted of contact lens intolerance or poor spectacle-corrected visual acuity. dalk was performed using the big-bubble technique introduced by anwar and...

purpose: evaluate the effect of relaxing incision and adjustment sutures to correct astigmatism after deep anterior lamellar keratoplasty (dalk) in patients with keratoconus. materials and methods: this interventional case series included keratoconic eyes undergoing graft refractive surgery (grs) for intolerable post-dalk astigmatism. the technique of graft refractive surgery for the 5 initial ...

purpose : to review the visual outcome and complications of deep anterior lamellar keratoplasty (dalk) using the big-bubble technique in patients with corneal ectasia methods : eighteen consecutive patients with keratoconus or post-lasik ectasia with poor spectacle-corrected visual acuity and/or contact lens intolerance were enrolled in this study between october 2005 and september 2006. dalk b...

purpose: to compare outcomes of two techniques (anwar vs. melles) of deep anterior lamellar keratoplasty (dalk) in patients with keratoconus. methods: this randomized double-blind clinical trial was performed on 57 eyes of 57 patients with keratoconus. patients aged 20-35 years with a clinical diagnosis of keratoconus who were contact lens intolerant and had corrected distance visual acuity (cd...
