|Official Title:||Phase 4 Study of Comparison Among 3 Different No-contact Instruments to Valuate Central Corneal Thickness|
- Central Corneal Thickness (CCT) expressed in microns (μm) [ Time Frame: partecipants will be followed for one day, i. e. until the CCT measurements with all instruments object of present study are taken ] [ Designated as safety issue: No ]to valuate differences among all obtained no-contact CCT measurements and compare them with the CCT measured with the reference tool (Ultrasound pachymeter).
- Central Corneal Thickness (CCT) expressed in microns (μm) [ Time Frame: partecipants will be followed for one day, i. e. until the CCT measurements with all instruments object of present study are taken ] [ Designated as safety issue: No ]to valuate test-retest reliability of each instrument

All recruited volunteers in present study, that underwent pachymetry measurement with four different instruments
Healthy volunteers recruited among subject that underwent a routine ophthalmologic evaluation or among both students and workers at our clinic, will be submitted to CCT measurement through four different instruments: Scheimpflug camera tomography, SD-OCT, anterior chamber SD-OCT, and finally with US pachymeter.
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.
