An analysis and interpretation of refractive errors after penetrating keratoplasty

Ophthalmology. 1981 Jan;88(1):39-45. doi: 10.1016/s0161-6420(81)35086-6.


Despite advances in microsurgical techniques, astigmatism after penetrating keratoplasty is still a perplexing problem. In this paper, using retrospective studies, experiments, and observations, the factors that seem most significant in creating excessive postoperative astigmatism are delineated. The difficulty of creating a circular recipient hole of the same size and shape as the donor button appears to be a prime area for clinical research and technical development.
