Effect of Intracorneal Ring Segments on Posterior Corneal Tomography in Eyes With Keratoconus

Keratoconus Clinical Trial

Official title:
Effect of Intracorneal Ring Segments on Posterior Corneal Tomography in Eyes With Keratoconus

Clinical Trial Summary

Our purpose is to analyze the changes induced in the posterior corneal surface in patients implanted with intracorneal ring segments for treatment of keratoconus. Patients are assessed with corneal imaging device preoperatively and at 1, 3, 6 and 12 months postoperatively.

Clinical Trial Description

Procedure: Femtosecond laser assisted implantation of intracorneal ring segments in keratoconus patients Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), refraction, keratometric (K) readings of the anterior and posterior surface, corneal asphericity (Q value) of the anterior and posterior surface, and anterior and posterior elevations are evaluated using a corneal imaging device preoperatively and at 1, 3, 6 and 12 months after surgery. ;
