We have observed corneal curvature changes from laser thermal keratoplasty with a Co:MgF2 laser. We studied corneal curvature changes in rabbits and have identified specific treatment patterns and laser parameters that can correct myopia and astigmatism. These corneal changes, some as large as 8 diopters, have been stable for at least one year, and slitlamp examination demonstrates clear central corneas with normal appearance.

Clostridial endophthalmitis is an aggressive rapidly progressive infection with potentially poor visual outcomes that can be transmitted from infected corneal allografts. Further investigation is needed to clarify the role of anaerobic donor rim cultures and the donor risk factors associated with recovering corneal allograft tissue contaminated with C. perfringens.
