Our Services
Custom-designed gas permeable and scleral lenses for patients with keratoconus, corneal irregularities, and complex prescriptions where conventional correction falls short.
"When standard lenses are not enough, a custom-designed solution can restore clarity that patients thought was no longer possible."
Advanced Contact Lens Fitting
At Dynamic Vision East Rand Mall, we specialise in fitting advanced hard contact lenses, including Gas Permeable (GP/RGP) and Scleral lenses, for patients with complex vision conditions that cannot be adequately corrected with spectacles or standard soft contact lenses.
These custom-designed lenses are individually crafted to the precise shape of your cornea, providing optical clarity and comfort that off-the-shelf solutions simply cannot achieve. For many patients, specialised contact lenses represent the most significant improvement in vision quality they have ever experienced.
Our practitioners combine advanced diagnostic technology with specialist fitting techniques to achieve the best possible outcome for each patient, regardless of the complexity of the prescription or corneal condition.

Hard and scleral contact lenses are particularly effective for patients whose corneas are irregular, unstable, or too complex for conventional correction.
A progressive condition in which the cornea thins and bulges into a cone shape. Keratoconus causes significant visual distortion that cannot be corrected with glasses or soft lenses. Scleral and RGP lenses are the most effective optical solution for most keratoconus patients.
Any condition where the corneal surface is uneven or distorted, including pellucid marginal degeneration, corneal ectasia, or irregular astigmatism, benefits from a rigid lens surface that creates a smooth, uniform optical interface over the cornea.
Patients who have undergone refractive surgery (LASIK, PRK) and experienced irregular outcomes often find that custom hard lenses restore the visual quality they hoped to achieve through surgery.
Following a corneal graft, the transplanted cornea rarely heals perfectly flat. Residual irregularity is common, and scleral lenses are frequently the best option for achieving clear, comfortable vision after transplantation.
If spectacles or soft contact lenses have been unable to deliver adequate vision correction, a specialised gas permeable or scleral lens assessment may reveal options that conventional practitioners have not explored.
Very high myopia, hyperopia, or irregular astigmatism can push the limits of what spectacle lenses or soft contacts can comfortably achieve. Hard contact lenses often provide sharper optics and better visual performance in these cases.
Medmont Corneal Topography
To ensure the highest level of diagnostic accuracy, we use the Medmont Corneal Topographer, one of the most advanced instruments available for mapping the corneal surface. This technology gives us a highly detailed, three-dimensional picture of your cornea that no standard eye chart or keratometer can provide.
This detailed corneal map is the foundation of every specialised lens design. Without it, fitting a custom hard lens is guesswork. With it, we can design a lens that fits your cornea precisely, maximising both comfort and optical clarity.
Detailed Corneal Mapping
The topographer measures thousands of points across the corneal surface, producing a colour-coded elevation map that reveals curvature, irregularities, and asymmetry invisible to standard instruments.
Accurate Condition Diagnosis
Topography is the gold standard for diagnosing keratoconus and other corneal dystrophies, detecting changes that begin long before symptoms appear. It is also used to monitor progression over time.
Custom Lens Design
Topographic data is used directly to design and order lenses that conform to the precise shape of your cornea, rather than relying on standard fitting sets or averaged measurements.
Ongoing Progress Monitoring
For progressive conditions like keratoconus, regular topography appointments allow us to track changes over time and adjust your lens design as your cornea evolves.
Lens Options
Both lens types are custom-designed and offer superior optics over soft lenses for complex prescriptions. The right choice depends on your corneal shape, condition, and lifestyle needs.
Option 01
Rigid gas permeable lenses are smaller-diameter hard lenses that sit directly on the cornea. They provide excellent optical clarity and durability, and are particularly effective for moderate keratoconus and high astigmatism.
Option 02
Scleral lenses are larger-diameter lenses that vault completely over the cornea and rest on the white of the eye (sclera). This design provides exceptional comfort and stability, and is ideal for advanced keratoconus, post-surgical corneas, and severe corneal irregularity.
The Process
Fitting a custom hard or scleral lens is a multi-step process that requires precision, patience, and specialist expertise. We guide you through each stage.
We review your vision history, current prescription, and ocular health. A comprehensive assessment determines whether specialised lenses are appropriate and which type is most likely to succeed for your specific condition.
Using the Medmont Corneal Topographer, we create a precise three-dimensional map of your corneal surface. This data drives the custom lens design and is the single most important step in achieving an accurate fit.
Trial lenses are applied and assessed using a slit lamp and fluorescein dye, which reveals exactly how the lens sits on the eye. Adjustments to the lens parameters are made until the fit and vision are optimised.
Once the optimal parameters are confirmed, your lenses are custom-manufactured to order. On collection, we ensure you are comfortable inserting, removing, and caring for your lenses before you leave.
"Many patients come to us having been told that nothing more can be done for their vision. In most cases, that simply is not true. A well-fitted scleral or gas permeable lens can change a patient's life, and that never gets old."

Common Questions
Everything you need to know before your specialised contact lens assessment.
Patient Experiences
"I have had keratoconus for over ten years and had almost given up hope of ever seeing clearly again. Mina fitted me with scleral lenses and the difference is remarkable. I can drive, read, and work at a screen without squinting. Cannot recommend this practice highly enough."
Andile Khumalo
Boksburg
"After my corneal transplant my surgeon referred me here for contact lens fitting. The topography appointment was thorough and the scleral lens fitting was done with real expertise. My vision is now better than it was before the transplant. Exceptional care."
Liezel du Plessis

"I tried several optometrists who could not help with my complex prescription. Mina was the first who actually took the time to map my corneas and fit proper RGP lenses. The clarity is incredible. I only wish I had come here sooner."
