Improved vision following penetrating keratoplasty for pseudophakic corneal edema--visual results.

We studied prospectively 20 consecutive eyes of 17 patients who underwent penetrating keratoplasty for pseudophakic corneal edema. Copeland intraocular lens implants were retained in all cases initially, although one implant was subsequently removed. The visual results were analyzed at 12 and 24 months. With a minimum of 12 months follow-up, 65% of eyes saw 20/40 or better, while 80% saw 20/80 or better. By 24 months, 80% saw 20/40 or better, while 95% saw 20/80 or better. Post-keratoplasty refractive surgery, consisting of relaxing incisions and/or wedge resections, was performed in six eyes.
