Comparison of Three Different No-contact Pachymetries

Corneal Thickness Clinical Trial

Official title: Phase 4 Study of Comparison Among 3 Different No-contact Instruments to Valuate Central Corneal Thickness

Status Recruiting

Clinical Trial Summary

Study wants to compare central corneal thickness (CCT) obtained through 3 different no-contact instruments and to compare them with contact ultrasound pachymetry, actually the gold standard technique.

Clinical Trial Description

Corneal pachymetry is the measurement of corneal thickness, usually expressed in microns (μ).

Pachymetry is systematically used for the monitoring of corneal oedema, for the management and assessment of the progression risk of the ocular hypertension, for the diagnosis, the management and follow-up of keratoconus, as well as it is important in the pre and postoperative management of corneal surgical procedures. CCT is a factor well known to influence tonometry. Its assessment is fundamental in glaucoma practice to allow a correct intraocular pressure (IOP) evaluation.

The purpose of this study is to compare CCT measurements using four different instruments:

Scheimpflug camera tomography, spectral-domain optical coherence tomography (SD-OCT), anterior chamber SD-OCT and ultrasound pachymetry. ;
