purpose: to evaluate the influence of donor characteristics (age, death-to-preservation time, preservation-to-surgery time, graft rating, and endothelial cell features) on clinical outcomes following deep anterior lamellar keratoplasty (dalk) in patients with keratoconus. methods: in this retrospective study, 290 consecutive keratoconic eyes underwent dalk using donor corneas of different quali...

purpose: to compare the clinical and paraclinical outcomes following deep anterior lamellar keratoplasty (dalk) using frozen versus fresh corneas in patients with keratoconus. methods: in this prospective, comparative interventional study, 16 frozen and 19 fresh corneas were used during dalk in keratoconus patients. big bubble technique was used in all patients. the two groups were compared at ...

purpose: to report a case of bilateral acanthamoeba keratitis with recurrence after keratoplasties case report: here we report a case with bilateral acanthamoeba keratitis who initially responds to medical treatment, after discontinuation of treatment the disease flared up and not responded to medical therapy so superficial keratectomy was done and medical treatment continued and the ulcer impr...

Keratoconus is a bilateral non-inflammatory corneal ectasia with an incidence of approximately one per 2000 in the general population. Contact lenses are the most common treatment. When contact lenses fail, a surgical approach is necessary for visual rehabilitation. Penetrating keratoplasty has been the traditional and most common mode of treatment and has excellent results. 3 However, more rec...

The use of femtosecond lasers has created an evolution in modern corneal and refractive surgery. With accuracy, safety, and repeatability, eye surgeons can utilize the femtosecond laser in almost all anterior refractive procedures; laser in situ keratomileusis (LASIK), small incision lenticule extraction (SMILE), penetrating keratoplasty (PKP), insertion of intracorneal ring segments, anterior ...

Purpose To determine whether a fibrin adhesive can facilitate the performance of sutureless lamellar keratoplasty and attachment of amnion to bare sclera.

purpose : to compare outcomes of penetrating keratoplasty (pk) and deep anterior lamellar keratoplasty (dalk) in keratoconic eyes in a university teaching hospital setting methods : in this longitudinal cross-sectional study all patients who underwent pk or dalk for keratoconus at 2 years period were included to the study. the patients were recalled and complete eye examination including best s...

MANY of the stationary corneal opacities causing diminution of vision are central, avascular, and superficial, and are surrounded by clear cornea or have a neighbouring peripheral clear corneal area of 4 x 4-5 mm. Donor homogenous corneal grafts are not always available, but a rectangular lamellar autogenous corneal. graft can be dissected and turned 1800 so that the clear lamellae are brought ...
