We care

about your eye health

The best choice

for your eyes

You are unique and so is your vision

West Rand Eye Care Centre is an ophthalmological practice where we create a professional and friendly atmosphere where staff are well-informed and every single patient counts. This practice takes care of all aspects of general ophthalmological care which include treatment and management of medical eye conditions such as Glaucoma, Diabetes and Macular Degeneration.

Each type of eye surgery is done uniquely to meet the special outcome required for good, comfortable and clear vision. These surgeries include cataract surgery, pterygium surgery, oculoplastic surgery and refractive surgery.

When it comes to refractive surgery, Dr. Derek de Beer uses the most specialized refractive excimer lasers like the SCHWIND AMARIS 750S and the ZEISS refractive suite.

The laser equipment includes our latest addition of a femtosecond laser that has opened up a whole new world of possibilities in laser corrective surgery. The SCHWIND AMARIS laser system has all the features of modern laser technology.

Eye and Visual Defects: A Brief Overview

Normal Eye (Emmetropia)

The normally seeing eye focuses light rays at a focal point on your retina. You can recognize objects clearly.
"For every beauty there is an eye somewhere to see it. For every truth there is an ear somewhere to hear it. For every love there is an heart somewhere to receive it."Ivan Panin


Astigmatism is a condition in which objects at all distances appear distorted due to a misshapen cornea. Instead of being spherical, the cornea has more curvature in one meridian than the other. It is shaped similar to a rugby ball.

Hyperopia (Farsightedness)

Hyperopia (far-sightedness) is a focusing problem caused by an eyeball that is shorter than normal and light rays focusing behind the retina.

Myopia (Shortsightedness)

Myopia (near-sightedness) is a condition in which close objects are seen clearly but distant objects appear blurred. Myopia results from a lengthened eyeball or cornea, which is curved too steeply resulting in a focus point in front of the retina.

Presbyopia (Aging Eye)

You may start to notice presbyopia around the age of 40, when you begin to hold reading materials further away from your face to see them more clearly. This familiar event is often the first sign of presbyopia, which, if left uncorrected, can cause eye fatigue and headaches./p>

Higher Order Visual Defects

Higher order visual defects can differ vastly from one individual to the next. Approximately 80% occur on the cornea and 20% in the lens and vitreous body situated behind the lens. These higher order defects will mostly affect vision at night, dusk and dawn. This is because the rays of light do not come together in one single point but are dispersed into two or more points. When the pupil dilates, an individual might experience significantly reduced sight or feel easily blinded.
