Cataract Eye Surgery Cape Town by Dr Frikkie Hartog

What is a cataract?

The natural crystalline lens of your eye is situated behind the colored ring (iris) of the eye. It is responsible for focusing incoming light on the retina (the innermost layer of the eye) thereby permitting sharp vision. This scenario is the ideal, but changes in the lens leads to spectacle errors, especially so after the age of approximately 45 years. This is called presbyopia. In time the lens also becomes cloudy, effectively blocking incoming light, leading to poor vision even with spectacle correction. This is known as a cataract, and cataract surgery affords the definitive solution.


The treatment of cataracts

During eye cataract surgery the content of the cloudy lens is removed and replaced with a plastic lens, the primary aim being to enable light to penetrate the eye unobstructed thereby improving vision, although with some spectacle correction still needed.

Dr. Frikkie Hartog also makes every effort to reach his secondary goal: reducing the spectacle error as much as possible allowing the patient to perform most of his daily activities without the need for any spectacle or contact lens correction. In order to achieve this goal Dr. Hartog makes use of the following:

  • Laser assisted measuring of the eye (optical biometry with the Nidek biometer and IOL Master) with the most up do date software in order to accurately calculate the ideal lens for each eye
  • The use of aspheric, toric (in order to reduce astigmatism) and multifocal lenses from a reputable company with a very long track record of excellence
  • Dr Hartog has used the same lenses since 2005 permitting optimization of the visual results from analysis of all his previous cataract surgeries thereby significantly improving his outcomes
  • Performing small incision surgery through a 2,2mm stab incision, permitting a speedy visual recovery
  • Cataract surgery is performed as a day procedure without the need for any stay in hospital.

What to expect with cataract surgery

Cataract surgery is performed on more than 22 million people worldwide every year, due to the fact that it is a safe and painless procedure producing excellent results. Cataract surgery is performed with a local anesthetic of the eye alone, and is completely painless with no discomfort afterwards. The safety and efficacy of the procedure is of paramount importance to Dr. Hartog, and therefore he uses the newest in phacoemulsification technology to remove the cataract in the Alcon Centurion Vision System.
