ABSTRACT
PURPOSE: To report four cases of split cornea transplantation involving separate Descemet membrane keratoplasty and Deep anterior lamella keratoplasty from a single cornea. CASE SUMMARY: Four donor corneas were separated into the endothelium and other layers. The endothelial layers were transplanted into 4 pseudophakic bullous keratopathy patients, and the other layers were stored in corneal storage media. Deep anterior lamella keratoplasties were performed with the stored corneas in 2 lipid keratopathy and 2 keratoconus patients. Postoperatively, all grafted corneas were stable. CONCLUSIONS: The authors report the first 4 cases of split cornea transplantation in Korea, which is experiencing a shortage of donated corneas. Split cornea transplantation will be of benefit to a large number of patients by separating a single cornea into separate layers to be implanted into two patients.

Seventy-six patients who visited Kang-Nam St. Mary's Hospital with keratoconus from 1982 to 1987 were reviewed retrospectively. At the time of diagnosis, the age-specific prevalence were greatest in the younger groups, with the rate for males being somewhat greater than that for females and the rate of bilateral involvement was greater than that of unilateral involvement. Of 126 eyes with. keratoconus, 76 achieved visual acuity of 0.3 or better with hard contact lens at the time of diagnosis. Thirty-nine received corneal graft and 38(97%) achieved visual acuity of 0.3 or better with correction. Keratoplasty can be delayed or avoided in many keratoconus patients by using contact lens, especially the specially designed lenses. Also keratoconus eyes often need contact lenses after keratoplasty.
