Conditions

Intraocular Pressure, Keratoconus

Brief summary

To evaluate the changes that occur in the intraocular pressure before and after corneal cross linking using Corvis CT.

Detailed description

This study will be prospective study. 50 Patients will be included who will undergo corneal cross linking from the out-patient clinic of Tanta University hospital between December 2025 and December 2026 will be included in the study . Patient with age 19 till 35 years old will be included Patient with Corneal scarring, Previous corneal infections, Minimum corneal thickness at the thinnest location less than 400 µm, History of uveitis or ocular allergy and Pre-existing glaucoma will be excluded from the study All patient will undergo full ophthalmological examination. including best corrected visual acuity, degree of myopia , average kertometry and intraocular pressure will be measured before and after cross linkage with three different techniques including Shiotz tonometry, appalanation tonometry and CORVIS machine
