Not yet recruiting

• Conditions: Refractive Errors

• Registration Number: NCT06166212
• Lead Sponsor: Ain Shams University

Brief Summary

Refractive errors and corneal astigmatism are associated with changes in angle kappa and corneal back elevation at the thinnest point in Pentacam.

The purpose of this study is to track:

The effect of anterior corneal astigmatism treatment on angle kappa and corneal back elevation.

Detailed Description

This prospective observational study will be settled in Ain Shams University Hospital, Cairo, Egypt.
