Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The patient will be thoroughly examined clinically on slit lamp detailed history will be obtained visual acuity will be measured and patient refraction will be taken then imaging on Sirius topographer will be used to obtain angle Kappa and high order aberrations of the cornea and I-design pentacam imaging will be used to get the total aberrations of the eye
