Graded Relaxing Incision Technique for Post-Keratoplasty Astigmatism

European Journal of Implant and Refractive Surgery, 1989
A technique of graded relaxing incisions and compression sutures was performed for correction of post-keratoplasty astigmatism in 6 patients who were spectacle and contact lens intolerant. All of these patients were able to achieve correction after surgery, 5 with spectacles, and 1 with a contact lens. Keratometric astigmatism decreased from an average

Paired arcuate keratotomy for congenital and post‐keratoplasty astigmatism

Acta Ophthalmologica Scandinavica, 1998
To study the effect of arcuate keratotomy on corneal astigmatism in previously grafted eyes compared to eyes with naturally occurring astigmatism.Twenty-three eyes with naturally occurring astigmatism and 21 eyes with post-keratoplasty astigmatism were treated by arcuate keratotomies in the steepest corneal meridian.

Correction of post-keratoplasty astigmatism with keratotomies in the host cornea

Journal of Cataract and Refractive Surgery, 2006
We evaluated the effects of astigmatic keratotomy performed in the host cornea to treat astigmatism after penetrating keratoplasty. In 11 patients with high post-keratoplasty astigmatisms (mean 9.02 diopters [D]; range 5.5 to 17.4 D), an arcuate keratotomy was performed in the host cornea. The mean incision depth was 575 mum (range 500 to 600 mum). The

Sequential selective same-day suture removal in the management of post-keratoplasty astigmatism [PDF]

Eye, 2013
In a previous study, we proposed that corneal topography performed 30-40 min after the initial suture removal can identify the next set of sutures requiring removal, for the treatment of post-keratoplasty astigmatism. The aim of this study was to evaluate the effect of removing subsequent sets of sutures at the same sitting.10/0 nylon interrupted ...

Post-keratoplasty Astigmatism

2015
Astigmatism is the leading factor to limit visual rehabilitation after otherwise successful keratoplasty. Reasons for post-keratoplasty astigmatism are multifactorial, and they can be divided into donor-related factors, recipient-related factors, intraoperative factors, and postoperative factors.

Implantable collamer lens for the correction of post-keratoplasty myopia and astigmatism

International Eye Research, 2020
AIM: To evaluate the safety, refractive outcomes and vision after phakic posterior chamber implantable collamer lens (ICL) after keratoplasty (KP). METHODS: This retrospective single center study evaluated 32 (35 eyes) patients who received an ICL for myopia and/or astigmatism after keratoplasty.

Outcomes of Femtosecond Laser-Assisted Arcuate Keratotomy in the Management of Keratoplasty-Related Astigmatism

Journal of Clinical Medicine
Background/Objectives: Post-keratoplasty astigmatism can limit visual recovery even after successful corneal transplantation. Femtosecond laser-assisted arcuate keratotomy (FSAK) has emerged as a method to reduce high residual astigmatism and enhance ...

Surgical Management of Post-Keratoplasty Astigmatism

2015
Penetrating keratoplasty (PK) with a clear graft results in improved visual acuity. However, visual acuity can be limited by significant postoperative astigmatism. There are currently several treatment options for post-PK astigmatism. Because of its moderate effectiveness and unpredictable outcomes, incisional surgery can be used to prime the cornea ...

Effect of hinged lamellar keratotomy on post‐keratoplasty astigmatism and vision

Clinical & Experimental Ophthalmology, 2004
Abstract Purpose: To show that hinged lamellar keratotomy alone affects refraction and vision in post‐keratoplasty eyes. Methods: A retrospective, non‐comparative, interventional case series was conducted on 28 eyes of 26 patients who had two‐stage laser in situ keratomileusis (LASIK) after penetrating keratoplasty.

The Effect of Relaxing Incisions With Multiple Compression Sutures on Post-Keratoplasty Astigmatism

Ophthalmic Surgery, Lasers and Imaging Retina, 1990
ABSTRACT We describe a surgical technique for correction of astigmatism following penetrating keratoplasty performed after all keratoplasty sutures have been removed. Two relaxing incisions of 3 clock hours, at 3/4 depth, 0.5 mm inside the keratoplasty wound are used in combination with two sets of three compression sutures placed 90° from ...
