The VX120+ is a multi-function diagnostic device combining corneal topographer, retro-illuminator, and pachymeter, indicated for: Measuring the refraction of the eye giving both lower and higher order aberrations Measuring the shape of the cornea Retro-illumination imaging of the eye Measuring the intraocular pressure without contacting the eye for glaucoma evaluation. Photographing the eye and taking images of the eye to evaluate the thickness of the cornea.
An electrically-powered, ophthalmic device designed to be used by a healthcare professional to objectively measure the refractive error of the eye (the inaccuracies of focusing light upon the retina) by measuring how light is changed when it enters the patient's eye(s). The device emits light into the eye and detects the light reflection which is measured for sphere, cylinder, axis and/or high order aberration measurements, typically measured in dioptres (the reciprocal of the focal length of the lens expressed in metres). Also known as an aberrometer, the device uses this information to automatically calculate the lens prescription needed to correct the patient's vision.
