Management of Post-Penetrating Keratoplasty Astigmatism
Penetrating keratoplasty (PK) has emerged as a relatively safe means of restoring vision in corneal opacities and irregularities. Astigmatism is the most common cause of suboptimal vision after corneal transplantation despite a clear corneal graft.1,2 Based on several studies,3615%–31% of patients undergoing PK may develop postoperative astigmatism greater than 5 diopters (D). The astigmatism c...

متن کاملLate onset post-keratoplasty astigmatism in patients with keratoconus
Aim: 10 eyes of 10 patients are reported where progression of keratoconus in the host cornea occurred more than 10 years after penetrating keratoplasty with resultant increase in astigmatism. The technique and results of graft refractive surgery in seven eyes are presented. Methods: The clinical features and management of these patients were retrospectively analysed.

متن کاملPost-keratoplasty astigmatism management by relaxing incisions: a systematic review
Postoperative visual acuity can be limited by post-keratoplasty astigmatism, even with a clear corneal graft. Astigmatism management can be performed by selective suture removal, adjustment of sutures, optical correction, photorefractive procedures, wedge resection, intra-ocular lens implantation, intracorneal ring segments, relaxing incisions with or without compression sutures and repeated ke...
