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…
The function of the tear film is to lubricate the ocular surface, provide protection against irritants and it plays a role in the refraction of light as it enters the eye.
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).
Corneal imaging creates a 3-dimensional model of the cornea which is useful for examining important parameters such as corneal curvature, power and thickness.
Myth: The eye only produces one type of tear Fact: Your body produces three types of tears

Your first visit to an ophthalmologist can be quite bizarre. Although it might seem very strange it can be compared to a normal visit to your GP. Like your GP…
Myth #2 - Vision loss as a result of glaucoma can be recovered. Fact – Vision loss from glaucoma occurs when axons in the optic nerve become damaged and can no longer carry visual information to the brain. Since glaucoma kills nerve cells that are truly part of the brain, it is not surprising that once vision is lost from glaucoma, it cannot be restored. That is why we call glaucoma the “silent thief of sight”.
