Effects of timolol and Daranide on elevated intraocular pressure after aphakic keratoplasty.

In a randomized, blind clinical study, we tested the effect of timolol and Daranide against placebo medications among patients who had intraocular pressures greater than 30 mm Hg on the first postoperative day after aphakic keratoplasty. The study failed to show any significant difference in the pressure course. We concluded that because this type of severe secondary glaucoma is extremely difficult to treat, it should be prevented by using a donor cornea larger in size than the recipient bed.
