DEVICE: VISIONIX (03664188002200)

An ophthalmic, battery-powered, measuring instrument designed for determining the intraocular pressure (IOP) by exerting an external force against the eye which provides a reading of the resistance of the tunica of the eye to deformation (the extent of corneal indentation) which is expressed in millimetre(s) of mercury (mmHg). This hand-held device (known as a contact type, e.g., a Perkins tonometer) is often used for, e.g., the examination of postoperative, bedridden and paediatric patients.

A mains electricity (AC-powered), ophthalmic, device that uses optics to measure the thickness of the cornea. Using optical low coherence reflectometry (OLCR) this device can possibly measure corneal thicknesses to a precision of one micron without having to make contact with the eye surface and no contact fluids are required, nor will it induce any indentation. This device, also known as a pachometer, will provide data that is used to evaluate the results of eye surgery [e.g., laser assisted in situ keratomileusis (LASIK) treatment], monitor epithelium regrowth, and for other ophthalmic measurement evaluations.
