Corneal Biomechanics in Ectatic Diseases: Refractive Surgery Implications
BACKGROUND Ectasia development occurs due to a chronic corneal biomechanical decompensation or weakness, resulting in stromal thinning and corneal protrusion. This leads to corneal steepening, increase in astigmatism, and irregularity. In corneal refractive surgery, the detection of mild forms of ectasia pre-operatively is essential to avoid post-operative progressive ectasia, which also depend...
متن کاملSurgical management of ectatic corneal disorders
Over the last decade there has been a paradigm shift from penetrating keratoplasty (PKP) to lamellar keratoplasty for the management of primary as well as acquired corneal ectasia. Several treatment modalities have emerged including collagen cross-linking, intrastromal implants, laser vision correction, and recent techniques in central and peripheral lamellar keratoplasty. This article reviews ...
متن کاملSurgical technique: coupling of intrastromal corneal ring segments for ectatic corneal disorders in eye bank corneas
The management of corneal ectasia is evolving, with intrastromal corneal ring segments playing an important role in delaying or eliminating the need for penetrating keratoplasty. This paper describes a modification in the implantation technique of intrastromal corneal ring segments that allows for coupling of the two segments with suture, affording more structural support.
متن کاملCorneal aberrometric and refractive performance of 2 intrastromal corneal ring segment models in early and moderate ectatic disease.
PURPOSE To evaluate and compare visual, refractive, and corneal aberrometric outcomes after implantation of 2 types of intrastromal corneal ring segments (ICRS) in eyes with early to moderate ectatic disease. SETTINGS Vissum Corporation-Instituto Oftalmológico de Alicante, Alicante, Spain. METHODS This retrospective analysis comprised consecutive eyes with grade I or grade II corneal ectasi...
متن کاملRefractive Surgical Correction Of Presbyopia With The Kamra Corneal Inlay
By Alois K. Dexl, MD, MSc Within the past few decades, various surgical procedures for the treatment of presbyopia have been implemented in cataract and refractive surgery. Recently introduced into the market was the Kamra corneal inlay (AcuFocus, Inc., Irvine, California). This inlay has the Conformité Europpeéne (CE) Mark and is currently commercially available in the European Union and other...
