What is LasikHD surgery?
The LasikHD surgery procedure involves the use of cool pulses of light to prepare the cornea for treatment. Immediately following corneal preparation, the cornea will be reshaped using a cool ultra-violet laser to evaporate a small amount of corneal tissue, which is thinner than that of a human hair.
Our highly qualified ophthalmologists at Visiomed Eye and Laser Clinic have unprecedented training and experience enabling them to professionally correct your vision using 100% bladeless laser technology.
Why choose LasikHD at Visiomed Eye and Laser Clinic?
The wait for better quality vision is finally over for millions of South Africans. Visiomed Eye and Laser Clinic has pioneered a new era in laser vision correction giving patients in South Africa the opportunity to free themselves from glasses and contact lenses. Many patients were once told that they do not meet the criteria to be a candidate; Visiomed Eye and Laser Clinic offers technological advances in laser vision correction making the procedure applicable for just about anyone.
- No reading glasses or contact lenses
Most patients adjust quickly to this procedure, thus eliminating their need for glasses or contacts.
- Painless procedure
Both eyes will be completely numbed using anaesthetic drops, so you will experience minimal to no discomfort.
- Leading surgeons
Leading eye surgeons at Visiomed Eye and Laser Clinic, together with world-class technology ensures personal, complete client satisfaction with numerous vision correction procedures.
World leading laser technology will fine-tune the way light is interpreted or refracted by the eye by gently adjusting and reshaping the cornea. Visiomed Eye and Laser Clinic is one of the first facilities to offer industry’s most recent advancements, the WaveLight EX500 Excimer laser technology. This technology yields better outcomes for vision correction surgery.
- Addressing unique eye problems
Until quite recently, eye laser refractive surgery was based on the assumption that all eyes with the same amount of short or long sight and astigmatism required exactly the same laser treatment. This assumption is incorrect. While two eyes may have the same degree of short sight and astigmatism, there are other optical errors present in both eyes that will not be the same.In the human eye, these differences are called optical errors and are known as “Higher Order (HO) aberrations”. If these HO aberrations are not corrected when doing refractive surgery, the eye may not reach its full visual potential.Visiomed Eye and Laser Clinic has recently acquired the latest laser technology to measure these Higher Order aberrations in the human eye. It is now possible to download your specific correction of HO aberrations electronically into the WaveLight® EX500 Excimer laser platform. This makes it possible for ophthalmologists to maximise the visual potential of your eyes, and to reduce the chances of less than optimal outcomes after surgery.
- Advanced diagnostics
During your personal consultation at Visiomed Eye and Laser Clinic, your ophthalmologist will use advanced diagnostics allowing them to fully map your eye. The surgeon plans patient specific surgical algorithms in precise locations and adjusts your treatment based on small changes or aberrations on your eye. This is what allows Visiomed Eye and Laser Clinic to revolutionise your vision.
LasikHD at Visiomed Eye and Laser Clinic successfully achieves high-quality vision correction for patients by personalising treatment to their individual refractive errors.
“Wavefront Optimized” and “Wavefront Guided” treatments allow for complete customisation for the patient’s individual eye.
The high definition diagnostic capabilities of the WaveLight® Topolyzer™ VARIO™ has been optimized to further enhance the patients’ refractive range and customized laser vision correction on the WaveLight® EX500 Excimer Laser’s platform.
The advanced design and built-in flexibility of the WaveLight® EX500 Excimer Laser allows surgeons at Visiomed Eye and Laser Clinic to expand their treatment capabilities by customising for all types of vision disorders (myopia, hyperopia, and astigmatism).
This will result in better quality vision in demanding situations such as poor lighting.
As part of the WaveLight® Refractive Suite at Visiomed Eye and Laser Clinic, the WaveLight® EX500 Excimer Laser has been ergonomically optimised to combine with the Ziemer® Z6 Femto second Laser and other WaveLight® diagnostic devices. By utilising the WaveNet™ Computer Network, surgeons can accurately transfer all patient data, treatment and diagnostic information directly to the lasers. The result is improved data flow throughout the procedure and enhanced patient experiences with a simplified surgical procedure. As the data is automatically transferred through the WaveNet it prevents manual uploading of patient data that reduces the possible chances of human error.
The first step in the LasikHD procedure involves the creation of a small flap in the eye’s outer corneal tissue. While traditional procedures use a blade for flap creation, Visiomed Eye and Laser Clinic is one of the first facilities in Johannesburg to adopt femtosecond laser technology. The Ziemer Z6 laser is the most advanced and accurate way to create the corneal flap before the Lasik procedure. The laser flap is more precise than traditional hand-made blade flaps and allows the eye to heal more quickly. The Z6 has many advantages:
- Comfort for the patient due to a shorter procedure.
- Faster visual recovery due to a smoother flap and 500 Hz operation.
- Reduced dry eye due to less laser energy use.
- Less inflammation and light sensitivity.
- Innovative engineering that reduces flap shrinkage and stromal dehydration of the cornea.
- Wavefront Optimized and Wavefront-Guided treatments for complete customisation for each patient.
- 1050 Hz-type multi-dimensional eye tracking for optimal precision and safety.
- Reduces the potential for nighttime glare.
Which eye problems does LasikHD surgery address?
The Visiomed Eye and Laser Clinic’s LasikHD surgery procedure will address nearsightedness, farsightedness and astigmatism.

Initial eye exam at Visiomed Eye and Laser Clinic
A 90 minute consultation will determine whether you are a candidate for laser vision correction. Your Visiomed Eye and Laser Clinic ophthalmologist will perform various tests similar to a normal eye examination as well as a scan of the eyes to determine certain Lasik related information.
During your consultation your ophthalmologist will:
- Test your visual acuity and visual field (peripheral vision).
- Measure your corneal thickness and topography (shape of the eye).
- Read your previous eye prescription using your glasses’ lenses.
- Examine your pupils for reactivity.
- Evaluate the muscle function and dominance of your eyes.
- Assess the health of your eye using a pupil dilatation slit-lamp test.
- Check for Glaucoma, assessing your eyes pressure.
- Inspect the health of your peripheral retina.
- Assess your overall medical health.
- Discuss your hobbies and occupation.
All of these factors will assist your ophthalmologist to determine whether you are a candidate for laser vision corrective surgery and which procedure is best suited for you. Once completed, this assessment will determine your unique treatment at Visiomed Eye and Laser Clinic.
Determining whether you are a LasikHD candidate.
