Corneal transplantation, as full-thickness transplantation, is an old surgical procedure which has been successfully performed for more than 100 years. However, in a last decade significant changes in surgical technique(s) have been implemented. The reason for such changes is the current trend to replace only the diseased part of the recipient cornea, not the whole cornea. Therefore, if the ant...

Descemet stripping automated endothelial keratoplasty (DSAEK) is the most common corneal transplant procedure. A key step in the procedure is preparing the donor cornea for transplantation. This can be accomplished via 1 of 3 alternatives: surgeon cuts the cornea on the day of surgery, the cornea is precut ahead of time in an offsite facility by a trained technician, or a precut cornea is purch...

We report the case of a 69-year-old female with Fuchs endothelial dystrophy and posterior chamber in-the-bag intraocular lens, whom we treated with DMEK surgical technique. We encountered difficulties both during obtaining the endothelium from the young donor and during the intraocular unrolling and its application on the stroma. We evaluated both preoperative and postoperative the following pa...

Monoclonal antibodies that recognize an epitope within the triple helix of type III collagen have been used to examine the distribution of that collagen type in human skin, cornea, amnion, aorta, and tendon. Ultrastructural examination of those tissues indicates antibody binding to collagen fibrils in skin, amnion, aorta, and tendon regardless of the diameter of the fibril. The antibody distrib...

purpose : to report a case with history of penetrating keratoplasty (pk) for keratoconus that developed acute hydrops in the recipient and donor cornea methods : a 46-year-old man, with history of bilateral keratoconus, who had undergone corneal transplantation in his left eye, presented with complaints of sudden visual reduction, photophobia, redness and pain of the left eye. results : review ...

THis new aid to corneal grafting has been designed to facilitate and simplify the operative procedure of lamellar keratoplasty. The instrument, a combination of blunt dissector and a cutting knife, has been used successfully as the basis of the new splitting technique in which an exact replica of the corneal disc removed from the recipient globe can be matched and replaced by a similar disc of ...

Keratoconus is a bilateral, asymmetrical, non-inflammatory, progressive disease, which induces a conical cornea and visual impairment because of biomechanical changes (1). Keratoplasty is an effective method for this ectatic corneal disorder, however, donor cornea is devoid seriously especially in Asia including China. Conservative treatment approaches could not prevent deterioration of the con...
