What this Trial Is About
This research evaluates the use of intra-corneal ring segments, known as INTACS, to correct high cylinder errors in non-ectatic corneas. The study aims to assess changes in visual acuity and corneal curvature in patients with significant astigmatism but without corneal ectasia. It is an interventional trial led by Elshimaa A. Mateen focusing on improving eye function through this procedure. Participants will receive INTACS implantation, which involves placing intra-corneal segments into the cornea to modify its shape and reduce astigmatism. The study follows patients over a period of six months to monitor changes in vision and corneal measurements. During the trial, researchers will measure visual acuity using the logMAR scale and assess keratometry readings in diopters to evaluate corneal curvature changes. They will also monitor high order aberrations and corneal parameters such as K1, K2, and K max. These assessments help determine the procedure's impact on eye structure and function throughout the six-month follow-up.
