RESUMEN
We reviewed retrospectively the records of 12 patients with herpes zoster keratopathy who had undergone penetrating keratoplasty. Preoperatively, seven patients (58%) had noninflamed eyes with visually significant corneal scarring or edema. Five patients (42%) had progressive neurotrophic corneal ulceration, and four of those had corneal perforation. Tarsorrhaphies were placed in ten patients and appeared to be beneficial in preventing postoperative breakdown of the corneal surface. At an average follow-up time of 36 months, ten of the 12 grafts (83%) remained clear, with nine patients (75%) having a visual acuity of 20/80 or better.

We report a case of presumed traumatic expulsion of an anterior chamber intraocular lens two weeks postoperatively. The 59-year-old patient presented complaining of foreign-body sensation; we found the intraocular lens in his superior conjunctival fornix.

A 77-year-old patient with low endothelial cell counts sustained acute unilateral endothelial decompensation when he traveled to an elevation of 12,500 feet. The corneal edema gradually increased after his return to sea level, and penetrating keratoplasty was required to restore vision. To our knowledge, this is the first reported case of hypoxia-induced corneal endothelial decompensation.
