CATARACT SURGERY
What is Cataract Surgery?
Cataract surgery is a procedure to remove the eye’s natural lens when it becomes cloudy, replacing it with a clear artificial intraocular lens (IOL). This restores vision clarity and improves overall eyesight. It is one of the safest and most effective surgeries performed worldwide.
Standard Cataract Surgery
This traditional method uses a small incision to manually remove the cloudy lens and replace it with a monofocal intraocular lens (IOL). While it effectively restores clear vision, patients may still require glasses for near or distance vision.
Premium Cataract Surgery
Premium cataract surgery offers advanced lens technology and laser-assisted techniques for enhanced vision correction. Options include:
- Multifocal or Trifocal IOLs – Reduce dependence on glasses for near, intermediate, and distance vision.
- Toric IOLs – Correct astigmatism for sharper vision.
- Extended Depth of Focus (EDOF) Lenses – Provide a continuous range of vision with minimal glare or halos.
- Laser-Assisted Cataract Surgery (LACS) – Uses femtosecond laser technology for more precise incisions and lens fragmentation.
- Improved Vision – Eliminates cloudiness and restores sharp, clear sight.
- Enhanced Quality of Life – Reduces dependence on glasses and allows for more active living.
- Safe & Effective – Cataract surgery is a proven, low-risk procedure with high success rates.
- Customizable Options – Premium lenses offer tailored solutions to fit different lifestyles and visual needs.
Cataract surgery is suitable for:
- Individuals experiencing blurry vision, glare, or difficulty reading.
- Patients with cataracts interfering with daily activities.
- Those seeking vision correction without heavy reliance on glasses.
- People with astigmatism or presbyopia who may benefit from premium IOLs.

LENS-BASED REFRACTIVE SURGERY
What is Lens-Based Refractive Surgery?
Unlike laser procedures that reshape the cornea, lens-based refractive surgery involves modifying or replacing the eye's natural lens to correct vision problems. It is particularly suitable for patients with high degrees of myopia or hyperopia or those with early cataracts.
- Implantable Contact Lenses (ICL) Implantable Contact Lenses are placed inside the eye, in front of the natural lens, without removing any corneal tissue. They are an excellent option for patients with high myopia or thin corneas unsuitable for laser procedures. ICLs provide sharp, high-quality vision and are removable, making them a reversible alternative to laser surgery.
- Refractive Lens Exchange (RLE) RLE involves replacing the natural lens with a synthetic intraocular lens, similar to cataract surgery but performed purely for vision correction rather than cataract removal. It is ideal for patients over 40 who are experiencing presbyopia or high refractive errors. This procedure eliminates the risk of cataract development in the future.
- Versatility: Suitable for a broader range of vision issues, including high myopia and presbyopia.
- Permanent Solution: Lens implants are long-lasting and reduce the need for spectacles or contact lenses.
- No Risk of Dry Eyes: Unlike corneal procedures, lens-based surgery does not affect the corneal nerves, reducing the risk of dry eye syndrome.
- Cataract Prevention: RLE prevents cataracts from developing in the future, ensuring clear vision for life.
Cataract and Lens-based refractive surgery is particularly suitable for:
- Patients with high myopia or hyperopia.
- Individuals over 40 experiencing presbyopia.
- Those with thin corneas are unsuitable for laser surgery.
- Patients with early cataracts seeking vision correction.
A consultation with Dr Anesu Madikane will help determine the most suitable option for you based on your eye health, age, and lifestyle.

Frequently Asked Questions
No, cataract surgery is not painful. The procedure is performed under local anesthesia, usually with numbing eye drops or a mild sedative. Most patients feel only mild pressure or no sensation at all during the surgery.
The surgery itself usually takes about 10-15 minutes per eye, though you should expect to be at the clinic for a few hours for preparation and post-operative care.
Premium cataract surgery includes advanced lens options and techniques to enhance vision beyond standard cataract surgery. These may include:
- Multifocal or Trifocal IOLs – Reduce dependence on glasses for near, intermediate, and distance vision.
- Toric IOLs – Correct astigmatism.
- Laser-Assisted Cataract Surgery – Uses a femtosecond laser for greater precision.
- Extended Depth of Focus (EDOF) Lenses – Provide a continuous range of vision with minimal glare or halos.
Most patients notice improved vision within 24-48 hours, though full recovery may take a few weeks. You may experience mild blurriness, light sensitivity, or dryness, which typically resolve over time.
The procedure typically takes 20 to 30 minutes per eye, with most patients resuming normal activities within a few days.
Yes, the results are generally permanent, and RLE eliminates the risk of cataract development.
Yes, ICLs are removable and replaceable, providing flexibility if vision needs to change over time.
The results of laser refractive surgery are generally permanent, though some changes to vision may occur naturally with age. Most patients experience long-term satisfaction, but annual check-ups are recommended to monitor your eye health.
Refractive Eye Surgery
Refractive eye surgery is designed to correct vision problems and reduce or eliminate the need for spectacles or contact lenses. It is broadly divided into two categories: Corneal Procedures (Laser Corrective Eye Surgery) and Lens-Based Procedures.
CORNEAL PROCEDURES: LASER CORRECTIVE EYE SURGERY
What is Laser Refractive Surgery?
Laser eye surgery is a highly advanced procedure that improves vision by reshaping the cornea and rectifying refractive errors such as nearsightedness, farsightedness, and astigmatism.
Benefits of Laser Eye Surgery
- Boost in confidence
- Improved vision
- Quicker recovery
- Long-term results
- Reduced dependence on eyewear
- LASIK (Laser-Assisted in Situ Keratomileusis)
LASIK is one of the most popular and widely performed laser refractive surgeries. It involves creating a thin flap in the cornea, which is then lifted to allow the laser to reshape the corneal tissue. The flap is repositioned, promoting rapid healing. LASIK offers quick recovery times and minimal discomfort, making it an ideal option for many patients.
- PRK (Photorefractive Keratectomy)
PRK is an alternative to LASIK, particularly suitable for those with thinner corneas or other corneal irregularities. In this procedure, the outer layer of the cornea is removed, and the underlying tissue is reshaped with the laser. While recovery may take slightly longer compared to LASIK, PRK provides excellent results with fewer risks for patients with certain corneal conditions.
- SMILE (Small Incision Lenticule Extraction)
SMILE is a minimally invasive procedure that involves removing a small piece of corneal tissue through a tiny incision. This advanced technique is ideal for patients with myopia and astigmatism. SMILE offers the benefit of a smaller incision and quicker recovery time compared to LASIK.
- Precision: Laser technology allows for precise reshaping of the cornea to correct vision problems with high accuracy.
- Quick Recovery: Most patients experience minimal downtime, with many returning to standard, day-to-day activities within a day or two.
- Long-Lasting Results: The results of laser refractive surgery are permanent for most patients, offering a lasting solution to vision correction.
- Reduced Dependence on Eyewear: Laser refractive surgery significantly limits or eliminates the need for spectacles or contact lenses.
Laser refractive surgery is ideal for people who are over 18 and have had stable vision for at least one year. A consultation with Dr Anesu Madikane will help determine if you are a suitable candidate for the procedure, considering your eye health, lifestyle, and vision goals.

- SMILE: Minimally invasive with a small incision and quicker recovery, ideal for myopia and astigmatism.
- RLE: Replaces the natural lens with an artificial one, ideal for presbyopia and high refractive errors.
- ICL: Implantable contact lenses positioned in front of the natural lens, suitable for high myopia or thin corneas.
The laser refractive surgery procedure typically takes about 10 to 15 minutes per eye, depending on the type of surgery. The majority of the time is spent preparing the eye, with the laser treatment itself taking only a few seconds.
The procedure is generally painless, as local anaesthetic eye drops are used to numb sensation in the eye. Some patients may feel mild discomfort or pressure during the procedure, but this typically subsides quickly.
Recovery time varies by procedure:
- LASIK: Most patients experience a quick recovery, often resuming normal activities within 24 to 48 hours.
- PRK: Recovery may take 3 to 7 days, with the initial healing period involving some discomfort. Vision improvement may continue for a few weeks.
- SMILE: Most patients see a faster recovery than with LASIK, typically resuming normal activities within a few days.
Laser refractive surgery is designed to reduce or eliminate the need for glasses or contact lenses. However, some patients may still need glasses for reading as they age due to presbyopia (age-related near vision changes). Dr Madikane will assess your suitability during your consultation.
You may be a suitable candidate if:
- You are over the age of 18.
- Your vision has been stable for at least one year.
- You do not have any significant eye conditions like cataracts or severe dry eye. A thorough consultation with Dr Madikane will help determine if laser refractive surgery is right for you.
While laser refractive surgery is generally safe and effective, like any surgical procedure, it carries some risks. These may include dry eyes, glare, halos around lights, or under/over-correction. Dr Madikane will discuss potential risks during your consultation and ensure you’re fully informed before proceeding.
