Astigmatism in Keratoconus Patients

Status Not yet recruiting

Clinical Trial Summary

Keratoconus is a bilateral (but usually asymmetrical) non-inflammatory progressive thinning process of the cornea. It manifests as characteristic cone-like ectasia of the cornea associated with irregular stromal thinning, resulting in a cone-like bulge , which causing irregular astigmatism and vision impairment.

Clinical Trial Description

Keratoconus is the most common form of corneal ectasia, with an incidence of 50-230 per 100,000 persons.Pentacam used diagnose & detect the progression in patients with keratoconus and also provide a detailed information about corneal tomography and topography.

In the last few years, it has been shown that in healthy individuals the posterior corneal surface has not only a different amount of astigmatism but also a different alignment of the steep meridian.

The aim of this research is to compare the amount and axis alignment of anterior and posterior corneal astigmatism in keratoconus with a healthy controlled group . ;
