About

Identification of the correlation between angle kappa , corneal high order aberrations and total eye aberrations in myopic hyperopic and astigmatic patients

Full description

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

Enrollment: 100 estimated patients
