Outpatient penetrating keratoplasty.

Elective penetrating keratoplasty has been performed on an outpatient basis on 37 patients since July 1987. The commonest indications have been herpetic keratitis, keratoconus, and pseudophakic or aphakic corneal oedema. Local anaesthesia, with little or no sedation, was used in most cases, and only three patients had a general anaesthetic. Accompanying procedures have included anterior vitrectomy, extracapsular cataract extraction with posterior chamber lens implantation and IOL exchange. The results demonstrate that outpatient keratoplasty is a safe, effective alternative to hospitalisation, and has a very high level of patient acceptance.
