Implantable Contact Lens Surgery in Pretoria: The Reversible Alternative to Laser

When most people think about permanent vision correction, laser eye surgery is usually the first thing that comes to mind. LASIK and SMILE have dominated the conversation for years, and for good reason. However, they are not the right solution for everyone.

For patients with high prescriptions, thinner corneas, or significant dry eye concerns, a different approach is often needed. That is where the Implantable Contact Lens comes in, and for many patients, it turns out to be an even better fit than laser surgery ever could have been.

The Implantable Contact Lens, commonly referred to as ICL, is a lens-based vision correction procedure that has been growing steadily in both popularity and awareness across South Africa. It offers an outstanding level of visual quality, is suitable for a broader prescription range than most laser procedures, and carries the unique distinction of being fully reversible if your needs ever change.

This guide covers everything you need to know about ICL surgery, from how it works and who it suits, to what the procedure and recovery experience look like with Dr Anesu Madikane.

What is an Implantable Contact Lens?

An Implantable Contact Lens is a small, biocompatible lens that is surgically placed inside the eye, between the natural lens and the iris. Unlike a standard contact lens that sits on the surface of the eye and needs to be removed daily, the ICL sits permanently inside the eye where it cannot be felt or seen. It works in harmony with your eye’s natural structures to correct your vision, and once it is in place, you simply do not notice it.

The lens used in ICL surgery is made from Collamer, a material that is uniquely biocompatible with the human eye. It contains a small amount of collagen, which allows it to integrate naturally with the eye’s environment without causing irritation or rejection. The ICL is designed to last indefinitely, but because it does not alter or remove any corneal tissue, it can be removed or replaced by a specialist if circumstances ever require it.

This preservation of corneal tissue is one of the most important distinctions between ICL and laser eye surgery. For patients who have been told their corneas are too thin for LASIK or SMILE, ICL opens the door to high-quality vision correction without any of the corneal considerations that laser procedures require.

Who is ICL Surgery Best Suited For?

ICL surgery is particularly well-suited to a specific group of patients, and understanding whether you fall into that group is what makes the initial consultation so valuable. The procedure is most commonly recommended for patients with moderate to very high myopia, particularly those whose prescriptions exceed what laser surgery can safely and effectively treat.

Patients who have been assessed and found to have thinner than average corneas are also strong candidates for ICL. Because the procedure does not touch the cornea at all, corneal thickness is simply not a limiting factor in the way that it is for LASIK or SMILE. This opens up vision correction to a group of patients who might otherwise have been told that no surgical option was available to them.

ICL is also a compelling option for younger patients with high prescriptions who are not yet in the age range for Refractive Lens Exchange, and for patients who experience significant dry eye symptoms that make corneal laser surgery a less appropriate choice. Because ICL does not affect corneal nerve tissue, it has a much lower association with post-operative dry eye compared to LASIK in particular.

To be a candidate for ICL, you generally need to be between 21 and 45 years of age, have a stable prescription, and have sufficient space within the anterior chamber of the eye to accommodate the lens safely. All of these factors are assessed in detail during your pre-operative evaluation with Dr Madikane.

How Does the ICL Procedure Work?

The ICL procedure is a minimally invasive surgical procedure performed under local anaesthetic, meaning you are awake but your eye is completely numbed throughout. The surgery itself typically takes around 20 to 30 minutes per eye and is performed with a high degree of precision.

A small micro-incision is made at the edge of the cornea, through which the folded ICL is gently inserted into the eye. Once inside, the lens unfolds and is carefully positioned behind the iris and in front of the natural lens. No tissue is removed, no corneal flap is created, and the micro-incision is so small that it seals naturally without the need for stitches.

Because the procedure is performed with local anaesthetic drops, you will not feel pain during the surgery. Some patients describe a mild awareness of light and movement, but the experience is generally calm and well-tolerated. Dr Madikane trained at the University of Edinburgh and completed advanced refractive surgery training at the London Vision Clinic, bringing a high level of surgical precision and patient-centred care to every procedure she performs.

The Reversibility Factor: What Makes ICL Unique

One of the most frequently discussed aspects of ICL surgery, and one that resonates strongly with patients who are cautious about committing to a permanent procedure, is the fact that the ICL is fully reversible. If your prescription changes significantly over time, if you develop a condition that requires a different approach, or if a new and improved lens technology becomes available in the future, the ICL can be removed and replaced by a qualified ophthalmologist.

This reversibility does not mean that ICL is a temporary solution. The vast majority of patients who undergo ICL surgery keep their lens for life with no need for removal or replacement. What it does mean is that you are not making an irreversible change to your corneal tissue, and that flexibility remains available to you if it is ever needed.

For patients who have been hesitant about laser eye surgery precisely because of its permanent nature, this aspect of ICL is often the deciding factor that makes them feel confident enough to move forward with vision correction.

ICL Recovery: What to Expect After Surgery

Recovery following ICL surgery is generally smooth and well-tolerated. Most patients notice a significant improvement in their vision within the first 24 hours after surgery, with continued refinement over the days that follow as the eye adjusts to the newly corrected vision.

In the initial days post-surgery, you may experience some mild light sensitivity, blurring, or haloes around lights, particularly at night. These are normal and typically resolve as healing progresses. You will be prescribed antibiotic and anti-inflammatory eye drops to use consistently during the recovery period, and lubricating drops will help keep the eye surface comfortable.

You will be seen by Dr Madikane for a follow-up appointment the day after surgery, with additional check-ins scheduled in the weeks that follow. Most patients are able to return to their normal daily routine within a day or two, though strenuous exercise, swimming, and activities with a risk of eye impact should be avoided for the period recommended by Dr Madikane based on your individual progress.

A Vision Correction Option Built Around You

ICL surgery represents a genuinely exciting option in the world of vision correction, particularly for patients who have been told that laser surgery is not suitable for them, or who simply want an approach that does not permanently alter their corneal tissue.

Every patient who walks into Dr Madikane’s practice is assessed as an individual. The goal is never to fit you into a procedure, but to find the procedure that fits you. For many patients, that procedure turns out to be the ICL, and the results speak for themselves.

Frequently Asked Questions

Is ICL surgery safe?

ICL surgery has an excellent long-term safety profile and has been performed worldwide for over two decades. The Collamer lens material is well-tolerated by the eye, and because no corneal tissue is altered or removed, the procedure avoids several of the risks associated with laser eye surgery. As with any surgical procedure, there are potential risks and side effects, all of which Dr Madikane will discuss with you in full during your consultation so that you can make a fully informed decision.

Can ICL correct astigmatism?

Yes. A toric version of the ICL is available specifically for patients with astigmatism, and it is highly effective at correcting both myopia and astigmatism simultaneously. During your pre-operative assessment, Dr Madikane will determine whether a standard or toric ICL is the appropriate choice based on your prescription profile.

How long does ICL surgery last?

The ICL is designed to be a permanent long-term solution and does not need to be replaced under normal circumstances. The Collamer material does not degrade over time, and the lens continues to provide clear vision for as long as it remains in the eye. Should circumstances ever change, the lens can be removed or exchanged, but this is rarely necessary.

Will I be able to feel the ICL once it is in place?

No. One of the most reassuring aspects of the ICL for patients is that once it is positioned inside the eye, it cannot be felt at all. There are no nerve endings in the area where the lens sits, and the biocompatible Collamer material integrates naturally with the eye’s environment. The vast majority of patients are entirely unaware of the lens once healing is complete.
