Purpose:
To evaluate a new technique for astigmatic keratotomy (AK) inpost-keratoplasty astigmatism management with femtosecond laser.
Methods:
6 post keratoplasty eyes of 5 patients were treated with femtosecondlaser (Intralase FS60, AMO) under topographic guidance. Arcuateincisions were placed within the donor cornea at the steep meridianof the preoperative corneal topography. Topographic measurementswere taken prior and post laser treatement(Orbscan II, B&L).
Results:
Pre- and postoperative topographic values are shown in table1, demographic patient data in table 2. There is a significantdecrease of Sim K (p<0.01), maximal keratometry and meanastigmatic power. There is a significant increase in minimalkeratometry, mean power and irregularity index.
Conclusions:
Femtosecond laser astigmatic keratotomy is a safe and effectivesurgical procedure for diminishing post-keratoplasty astigmatism
