Late onset post-keratoplasty astigmatism in patients with keratoconus [PDF]

open access: yesBritish Journal of Ophthalmology, 2004
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.The clinical features and management of these patients were retrospectively analysed.

Post-keratoplasty astigmatism management by relaxing incisions: a systematic review [PDF]

open access: yesEye and Vision, 2017
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 ...

AcrySof toric intraocular lens for post-keratoplasty astigmatism

open access: yesIndian Journal of Ophthalmology, 2012
We report a 63-year-old male who had undergone left eye optical penetrating keratoplasty for central leucomatous corneal opacity 10 years earlier. The eye had clear donor graft with residual astigmatism of -6.50 diopter cylinder (DC) at 30°. The patient underwent clear corneal phacoemulsification with implantation of +6.0 D spherical equivalent AcrySof

Repeated Femtosecond Laser-Assisted Astigmatic Keratotomies in Post-Keratoplasty Eyes

open access: yesJournal of Clinical Medicine, 2022
Visual rehabilitation after a keratoplasty is often compromised due to high amounts of residual astigmatism. Femtosecond laser-assisted astigmatic keratotomy (FLAK) is gaining popularity in decreasing this astigmatism. Though one set of two incisions suffices in most cases, sometimes the treatment proves insufficient and additional treatment is ...

EFFECT OF ARCUATE INCISION ON POST-KERATOPLASTY ASTIGMATISM [PDF]

open access: yesActa Medica Iranica, 1995
This work is a report 0/9 cases ofarcuate incision for correction 0/astigmatism, after penetrating keratoplasty. Plannings were based OJJ corneal topography, and the first operation was always arcuate incision alone. 11,e secondary plans were based on refractive errors. The mean of preoperative astigmatism was 6D with the range of5 to 9/).

Laser in situ keratomileusis to correct post-keratoplasty astigmatism

open access: yesJournal of Cataract and Refractive Surgery, 2004
To investigate the correction of post-penetrating keratoplasty (PKP) astigmatism using laser in situ keratomileusis (LASIK). Visual and refractive outcomes were evaluated after LASIK was performed in 1 step (lamellar cut and ablation in 1 procedure) or 2 steps (lamellar cut then ablation in 2 successive procedures).Department of Cornea and Refractive ...

The correction of post-keratoplasty astigmatism [PDF]

open access: yesEye, 1987
The results of refractive surgery for post-keratoplasty astigmatism in 41 eyes are presented. Thirty-nine eyes regained a functional vision of 6/12 or better. Relieving incisions and compression sutures are the most useful procedures, but more than one operation may be required.

Evaluation of interface quality in organ-cultured lamellar corneal transplants [PDF]

open access: yes, 2012
Background: With increasing numbers of lamellar keratoplasties, eye banks are challenged to deliver precut lamellar donor tissue. In Europe, the most common technique of corneal storage is organ culture which requires a deswelling process before surgical

Treatment of post‐keratoplasty astigmatism by topography supported customized laser ablation [PDF]

open access: yesActa Ophthalmologica Scandinavica, 2001
ABSTRACT. Purpose: To evaluate the clinical and optical efficiency of topography modulated customized corneal ablations for irregular corneal astigmatism.Material & methods: Sixteen eyes of 16 patients with iatrogenic corneal astigmatism (post keratoplasty) were consecutively included.

Intrastromal Corneal Ring Segments Implantation After Deep Anterior Lamellar Keratoplasty for Astigmatism Correction: Mid-term and Long-term Follow-up

open access: yes, 2023
Purpose:The aim of this study was to assess the long-term outcomes of implanting intrastromal corneal ring segments (ICRSs) using a femtosecond laser for correcting astigmatism in patients who had previous deep anterior lamellar keratoplasty (DALK ...
