简要总结
After corneal transplantation, topical corticosteroids are used to reduce the risk of rejection.
However, the optimal postoperative treatment regimen is unknown. In most cases, a topical steroid is administered for at least 6 months after surgery, but it remains to be determined whether potent steroids offer better protection than weak steroids. Also, the length of the treatment is debated.
Since the use of steroids is not without potential serious ocular side effects, it is of considerable importance to investigate these problems.
The study aims to examine the frequency of rejection episodes after posterior lamellar keratoplasty; specifically comparing a short course of potent steroids versus a long course of weak steroids.

研究组 & 干预措施
Weak steroid
Initial treatment with dexamethasone 6x per day for two weeks, followed by Fluorometholone 4x per day for 2 months, 3x per day for 2 months, 2x per day for 2 months, and finally 1x per day continually during 2 years.
干预措施: Weak steroid (Flurolon, Allergan) (Drug)
Potent steroid
Initially Dexamethasone 6x per day for 2 weeks followed by 4x per day for one month, 3x per day for one month, 2x per day for one month, and finally 1x per day for one month - giving a total of 4,5 months of steroid treatment.
干预措施: Potent steroid (Maxidex, Alcon) (Drug)
