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 کاملeffect of relaxing incisions for post penetrating keratoplasty astigmatism on graft curvature
purpose: to evaluate changes in graft steepness after graft refractive surgery (grs) and to discover influential factors and a coefficient to predict the amount of postoperative shift. methods: keratoconic patients with history of penetrating keratoplasty (pkp) who underwent grs due to high post-pkp astigmatism were included. changes in mean keratometry after grs were evaluated to find possible...
متن کاملLASIK for post penetrating keratoplasty astigmatism and myopia.
AIMS To report the results of a series of patients who were treated with LASIK to correct post penetrating keratoplasty ametropia. METHODS 26 eyes of 24 patients underwent LASIK to correct astigmatism and myopia after corneal transplantation; 14 eyes also received arcuate cuts in the stromal bed at the time of surgery. The mean preoperative spherical equivalent was -5.20D and the mean preoper...
متن کاملcurrent approaches for management of post-penetrating keratoplasty astigmatism
in addition to graft clarity, an acceptable refractive error is essential to consider a corneal transplant successful. the most common complication of penetrating keratoplasty (pk) is postkeratoplasty astigmatism which can result in decreased visual acuity, anisometropia, and mono-ocular diplopia. these complications can cause patient dissatisfaction, in spite of a successful transplant. intrao...
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. Graft refractive surgery in...
