PURPOSE To evaluate the clinical outcomes after implantation of the MyoRing (DIOPTEX GmBH, Linz, Austria) by means of femtosecond laser technology in eyes with corneal ectasia. DESIGN Retrospective, consecutive, nonrandomized, case series. PARTICIPANTS A total of 12 eyes of 11 patients with ages ranging from 17 to 50 years were included. All cases were diagnosed with corneal ectasia accordi...

Corneal refractive surgeries for the correction of myopia, hyperopia, astigmatism and hyperopia are quick and effective procedures, and have been growing in popularity over the last two decades. However, post-surgery corneal ectasia remains one of the most feared surgical complications. This is where the biomechanical integrity of the cornea begins to fail, with progressive thinning of the stro...

PURPOSE To evaluate the clinical outcomes of intrastromal corneal ring segment (ICRS) implantation to correct ectasia in eyes with prior refractive surgery. METHODS Forty-one eyes of 25 patients (13 men, 12 women; mean age, 28.66 years) with ectasia after refractive surgery [photorefractive keratectomy (PRK) or laser in situ keratomileusis (LASIK)] were included in a nonrandomized, retrospect...

Francois Malecaze MD commenced the session with an update on current research into the genetics of keratoconus. Dr Malecaze noted that forme fruste keratoconus is one of the major causes of post-LASIK corneal ectasia and the condition may be due to genetic factors in the majority of cases. Identification of the gene or genes responsible for keratoconus might lead to the development of blood tes...

We read with interest the editorial entitled “Corneal Cross-linking (CXL): Standardizing Terminology and Protocol Nomenclature.”1 We would like to clarify that we recommended the use of the term “corneal crosslinking” in a previous publication.2 For the sake of completeness, a comprehensive bibliography supporting this claim is added here for the journal’s readers.3-6 In the same editorial, we ...

PURPOSE To investigate the repeatability and reproducibility of the Visante Omni topography in obtaining topography measurements of rabbit corneas and to develop a post-surgical model of corneal ectasia. METHODS Eight rabbits were used to study the repeatability and reproducibility by assessing the intra- and interobserver bias and limits of agreement. Another nine rabbits underwent different...

Alport Syndrome is a hereditary disease that is caused by a gene mutation and affects the production of collagen in basement membranes; this condition causes hemorrhagic nephritis associated with deafness and ocular changes. The X-linked form of this disease is the most common and mainly affects males. Typical ocular findings are dot-and-fleck retinopathy, anterior lenticonus, and posterior pol...
