Outcome Measures
Primary Outcomes (1)
Central Corneal Thickness (CCT) expressed in microns (μm)
to valuate differences among all obtained no-contact CCT measurements and compare them with the CCT measured with the reference tool (Ultrasound pachymeter).
partecipants will be followed for one day, i. e. until the CCT measurements with all instruments object of present study are taken
Secondary Outcomes (1)
Central Corneal Thickness (CCT) expressed in microns (μm)
partecipants will be followed for one day, i. e. until the CCT measurements with all instruments object of present study are taken
Study Arms (1)
Pachymetry
All recruited volunteers in present study, that underwent pachymetry measurement with four different instruments
Interventions
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.
Eligibility Criteria
Healthy volunteers recruited among subject that underwent a routine ophthalmologic evaluation or among both students and workers at our clinic
You may qualify if:
- subjects that gave a valid consensus to be included in this experimentation,
- aged between 18 and 75 years,
- Best-Corrected Visual Acuity (BCVA) of 20/100 or better,
- refraction included between -6 and +6 dioptres,
- astigmatism included between -2 and +2 dioptres.
You may not qualify if:
- History of refractive surgery or any keratoplasty procedure,
- corneal opacities or diseases that make not suitable applanation tonometry or pachymetry.
- Use of contact lenses.
- History of corneal dystrophies or degenerative diseases, (like keratoconus and pellucid marginal degeneration).
- History of glaucoma or ocular hypertension.
