Storage, surgery outcome, and complications of corneal and conjunctival grafts

Recent articles related to corneal storage, surgery outcome, and complications of corneal and conjunctival grafts are reviewed. It appears that the addition of insulin and human epidermal growth factor may benefit storage solutions. Several multivariant analyses of risks for graft rejections are included, and include corneal vascularization, failed previous grafts, and preoperative endothelial damage. Transverse keratotomy as a method of controlling astigmatism after grafting may be effective. The incidence of acute hydrops in patients with keratoconus is about 2.8%. Free conjunctival grafts are reported to be useful in repairing failed filtering blebs and persistent bleb leaks.
