Post-keratoplasty astigmatism management by relaxing incisions: a systematic review.

Eye Vis (Lond) 2017 6;4:29. Epub 2017 Dec 6.

Ophthalmology Department, Aix-Marseille University - APHM, Hôpital de la Timone, 264 rue Saint Pierre, 13 385 Marseille Cedex 5, France.

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 keratoplasty. Relaxing incisions can be made in the graft, graft-host interface or host cornea. Read More

A numerical-experimental protocol to characterize corneal tissue with an application to predict astigmatic keratotomy surgery.

J Mech Behav Biomed Mater 2017 10 15;74:304-314. Epub 2017 Jun 15.

Applied Mechanics and Bioengineering (AMB), Aragón Institute of Engineering Research (i3A), University of Zaragoza, Zaragoza, Spain; Centro de Investigación Biomédica en Red: Bioingeniería, Biomateriales y Nanomedicina (CIBER-BBN), Zaragoza, Spain.

Tonometers are intended to determine the intraocular pressure (IOP) and the quality of corneal tissue. In contrast to the physiological state of stress of the cornea, tonometers induce non-physiological bending stress. Recently, the use of a single experiment to calibrate a set of corneal mechanical properties was suggested to be an ill-posed problem. Read More

[Implantation of a sulcus-fixated toric additive intraocular lens in a case of high astigmatism after a triple procedure].

Klin Monbl Augenheilkd 2014 Aug 15;231(8):788-92. Epub 2014 Jul 15.

International Vision Correction and Research Centre (IVCRC) & David J Apple Laboratory on Ocular Pathology, Augenklinik der Universität Heidelberg.

Background: Residual refractive errors, especially high-grade astigmatism after penetrating keratoplasty, often lead to a significant loss of vision. If high anismetropia could not be corrected with glasses or contact lenses, different kinds of surgical procedures are available for visual rehabilitation (intraocular lens exchange, astigmatic keratotomy, Excimer laser treatment, intrastromal corneal ring segment implantation and additive intraocular lens implantation). Toric add-on IOLs are especially designed for sulcus implantation and correcting high astigmatism in pseudophakic eyes. Read More

Purpose: To report a novel application of collagen cross-linking (CXL) in refractive astigmatic enhancement of previously performed astigmatic keratotomy.

Methods: A 28-year-old woman with prior history of bioptics correction of high myopic astigmatism with femtosecond laser-assisted astigmatic keratotomy followed by topography-guided LASIK showed long-term regression of the astigmatism 4 years later. A novel CXL application was employed in an attempt to reverse the regression of the astigmatic keratotomy. Read More
