Pre-screening consists of a series of tests which are performed on every patient before consulting with the ophthalmologist. These include an assessment of visual acuity, pressure and refraction (a glasses…

During cataract surgery the aging crystalline lens is removed and replaced with a new artificial lens. The required lens power is different for every patient and depends on the type and amount of refractive error (short-sightedness, far sightedness or astigmatism).
The HD Analyzer is a sophisticated instrument which is able to quantify the amount of light scatter within the eye.
Corneal imaging creates a 3-dimensional model of the cornea which is useful for examining important parameters such as corneal curvature, power and thickness.
Visual Field Testing (Perimetry) is the systematic assessment of visual function within the visual field.
The OCT is an imaging technique which forms an essential part of the ophthalmic assessment in the 21st century.
