corneal regrafts for correction of post-keratoplasty anisometropia and high astigmatism in two patients with keratoconus

Late 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...

Toric intraocular lenses for correction of astigmatism in keratoconus and after corneal surgery

PURPOSE To describe the results of cataract extraction with toric intraocular lens (IOL) implantation in patients with preexisting astigmatism from three corneal conditions (keratoconus, postkeratoplasty, and postpterygium surgery). METHODS Cataract patients with topographically stable, fairly regular (although sometimes very high) corneal astigmatism underwent phacoemulsification with implan...

Importance of Posterior Corneal Astigmatism in Eyes with Keratoconus

Evaluation of Corneal Aberrometry Parameters Before and After Cross-Linking in Patients with Keratoconus

Background and Objective: In the last decade, cross-linking (CXL) has been widely used for treating people with progressive keratoconus. The present study aimed to compare corneal aberrometry parameters before and after CXL in patients with keratoconus. Materials and Methods: In this cross-sectional study, 67 patients with keratoconus referred to Farshchian Sina Medical Education Center, Hamad...

femtosecond laser arcuate keratotomy for the correction of postkeratoplasty high astigmatism in keratoconus

background: astigmatism is the leading complication in visual recovery after penetrating keratoplasty (pkp) and deep anterior lamellar keratoplasty (dalk); in this study, we evaluated the outcome of femtosecond laser arcuate keratotomy (flak) after dalk and pkp in iranian keratoconic patients. materials and methods: in this prospective interventional case series, refractive and keratometric pre...
