TREATMENT OF GROSS CORNEAL OPACIFICATION BY LAMELLAR AND ANNULAR LAMELLAR KERATOPLASTY*t
PERFORATING keratoplasty is found to be most successful in cases of small central corneal nebulae and keratoconus. In both these conditions the graft lies completely surrounded by healthy cornea. Where there is gross opacification extending widely throughout the thickness of the cornea and especially if degenerative changes are present, then a simple perforating graft rapidly becomes completely...

متن کاملLamellar keratoplasty for the treatment of feline corneal sequestrum.
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...
متن کاملLamellar keratoplasty with lyophilized tissue for treatment of corneal scarring.
BACKGROUND A pilot study was carried out in Pakistan to assess the feasibility of the use of lathed freeze-dried corneal tissue in the treatment of corneal scarring. METHOD Six eyes underwent lamellar keratoplasty and were followed up for 18 months. RESULTS Visual improvement was obtained in every eye. In one eye, the procedure was complicated by delayed epithelialization of the graft, but ...
متن کاملCorneal ectasia following deep lamellar keratoplasty.
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...
