Used Ophthalmic Equipment(Please scroll down for our products) Ophthalmology literally means "The science of eyes." As a discipline it applies to animal eyes also, since the differences from human practice are surprisingly minor and are related mainly to differences in anatomy or prevalence, not differences in disease processes. An autorefractor or automated refractor is a computer-controlled machine used during an eye examination to provide an objective measurement of a person's refractive error and prescription for glasses or contact lenses. This is achieved by measuring how light is changed as it enters a person's eye. A fundus camera or retinal camera is a specialized low power microscope with an attached camera designed to photograph the interior surface of the eye, including the retina, optic disc, macula, and posterior pole. A keratometer, also known as a ophthalmometer, is a diagnostic instrument for measuring the curvature of the anterior surface of the cornea, particularly for assessing the extent and axis of astigmatism. A lensmeter , or lensometer is an ophthalmic instrument. It is mainly used by optometrists and opticians for verifying the correct prescription in a pair of eyeglasses. A phoropter (or phoroptor) is an instrument commonly used by optometrists and ophthalmologists during an eye examination to measure an individual's refractive error and determine his or her eyeglass prescription. Pupilometer is the name used for two different devices -- one that measures the distance between pupils, and one that measures the pupil's response to visual stimuli. A tonometer is an instrument for measuring tension or pressureA tonometer is an instrument for measuring tension or pressure. In ophthalmology, tonometry is the procedure eye care professionals perform to determine the intraocular pressure (IOP), the fluid pressure inside the eye. It is an important test in the evaluation of ocular conditions such as glaucoma as well as conditions such as phthisis bulbi, and iritis. Most tonometers are calibrated to measure pressure in mmHg.
