Lamellar endothelial surgery has gained increasing popularity in the last decade. This surgery is generally considered less invasive and allows faster recovery. However, differently from standard perforating keratoplasty, donor and recipient tissues are placed one over the other, and an interface is created between these two. The purpose of this review is to summarise findings of interface as o...

Methods: A 41⁄2 year old male patient with reduced vision and photophobia as a result of a centrally dense mid-stromal corneal scar in the right eye was referred to Gavin Herbert Eye Institute, University of California, Irvine, by an out of state ophthalmologist for consideration of femtosecondassisted laser lamellar keratoplasty. Following a complete ocular examination, FALK was performed unde...

PURPOSE To evaluate the outcomes of the hybrid technique of posterior lamellar keratoplasty (DMEK-S). MATERIALS AND METHODS 71 eyes of 55 patients enrolled in a single-center study underwent posterior lamellar keratoplasty with a hybrid lamella DMEK-S implanted using a solution implantation technique, owing to endothelial dysfunction. The outcome measures studied were visual acuity and endoth...

purpose: to compare the outcomes of deep anterior lamellar keratoplasty (dalk) using the big-bubble technique with that of penetrating keratoplasty (pk) in patients with keratoconus. methods: this double-blind clinical trial included patients with moderate to advanced keratoconus and poor spectacle-corrected visual acuity or contact lens intolerance. refractive errors, best corrected visual acu...

A lamellar keratoplasty was used to treat corneal sequestrum in four Persian cats (six eyes). Following a superficial keratectomy, lamellar corneal allografts (feline corneal tissue) or heterografts (canine corneal tissue) which had been preserved at -20 degrees C were placed in the recipient cornea. All grafts became optically transparent within 2 months following surgery and no recurrences of...

AIMS To evaluate corneal electrolysis as a treatment for recurrent diffuse corneal opacities at the host-graft interface of the stroma or at the subepithelial region in two types of granular corneal dystrophy (GCD). METHODS Recurrence developed at the host-graft interface of the stroma after lamellar keratoplasty in a patient with Avellino corneal dystrophy (ACD). At surgery, the deep aspect ...

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...

OBJECTIVE To examine the long-term safety and efficacy of hyperopic automated lamellar keratoplasty (H-ALK) for correction of primary hyperopia and for consecutive hyperopia following overcorrected myopic refractive surgery. METHODS A prospective study was done on 67 eyes of 50 consecutive patients who underwent H-ALK between March 17, 1993, and August 18, 1995. Hyperopic automated lamellar k...

INDICATIONS for lamellar corneal grafts are somewhat more numerous than those for penetrating keratoplasty, and Paufique, Sourdille, and Offret (1948) mention, besides the usual optical reason for replacing a corneal scar, tectonic, preparatory, aesthetic, and therapeutic indications. This last, designed to interrupt the course of chronic and recurrent corneal disorders, is of peculiar interest...
