Evaluation of the Change in the DA Ratio, IR and SSI as Parameters of Corneal Biomechanics Post Different LVC Procedures

Corneal Biomechanics Clinical Trial

Official title: Evaluation of the Change in the Deformation Amplitude Ratio, Integrated Radius and Stress Strain Index as Parameters of Corneal Biomechanics Post Different Laser Vision Correction Procedures

Status Completed

Clinical Trial Summary

In the study, The Investigators will compare the participates' corneal biomechanical properties including:

Deformation Amplitude ratio (Da Ratio) Integrated Radius (IR) Stress strain index (SSI)

All measurements will be taken before and after 3 months of LVC.

Clinical Trial Description

Each Participant will undergo preoperative pentacam and corvis scan for his eyes and the 3 months post operative.

The participants are divided into 3 groups, one who underwent LASIK, one PRK and one Femto LASIK.

Collected data will before and after surgery will be compared in each arm and then the 3 arms will be compared together. ;
