Size of donor corneal button and outflow facility in aphakic eyes.
Outflow facility was measured in 6 human eye bank eyes following penetrating keratoplasty and cataract extraction. A 7.5 mm corneal button was removed and replaced by an 8 mm button using conventional mid-to-deep stromal sutures. Baseline outflow facility in the phakic eyes (0.28 +/- 0.12 microliter/min/mm Hg, mean +/- SD) was unchanged (0.29 +/- 0.12) following the cataract extraction and penetrating keratoplasty using the larger corneal button.
