Cataract surgery is the most commonly performed surgical procedure in South Africa for adults over 60. Cataracts — a clouding of the eye's natural lens — cause progressive vision loss that can eventually lead to blindness if untreated, but are completely reversible with surgery. From a medical aid perspective, cataract surgery is a PMB Diagnosis and Treatment Pair, meaning your scheme must fund the procedure. However, the choice of replacement lens (IOL — intraocular lens) determines how much you pay out of pocket.
What Are Cataracts?
A cataract forms when proteins in the eye's natural crystalline lens begin to clump together, causing the lens to become cloudy. This typically develops gradually with age (age-related cataracts), though cataracts can also develop from diabetes, steroid use, trauma, and UV exposure (particularly relevant in SA).
Symptoms: Blurry or hazy vision, increased glare and halos from lights (especially at night), faded colours, and double vision in one eye. Reading and driving become progressively more difficult.
Surgical treatment: Cataract surgery involves removing the cloudy natural lens (via phacoemulsification — ultrasound-based) and replacing it with an artificial intraocular lens (IOL). The procedure takes 15–30 minutes per eye, is usually performed as a day procedure under local anaesthetic/sedation, and has a >95% success rate for restoring functional vision.
Is Cataract Surgery a PMB Condition?
Yes. Cataract surgery is a PMB Diagnosis and Treatment Pair.
Your scheme must fund cataract surgery when the clinical criteria are met (significant vision impairment affecting daily function). PMB covers: - The surgical procedure (phacoemulsification + IOL implantation) - Hospital day procedure facility - Anaesthetist - Post-operative follow-up consultations
PMB covers a standard monofocal IOL — a lens that corrects vision for one distance (usually distance vision; reading glasses are still needed). Premium IOL upgrades are not PMB-mandated.
The Lens Upgrade Question — Standard vs Premium IOL
This is the key financial decision in cataract surgery.
Standard monofocal IOL (scheme-funded): - Corrects distance vision - Reading glasses needed post-operatively for most patients - Very effective; appropriate for most patients - Funded at scheme tariff under PMB
Premium IOL options (OOP upgrade): - Multifocal IOL: Corrects both distance and near vision; may reduce or eliminate need for reading glasses. OOP cost: R8,000–R20,000 per eye above scheme contribution. - Extended depth of focus (EDOF) IOL: Intermediate range improved; fewer dysphotopsia side effects than multifocal. OOP: R7,000–R16,000 per eye. - Toric IOL: Corrects astigmatism in addition to cataract. Meaningful if you have significant corneal astigmatism. OOP: R5,000–R12,000 per eye. - Premium monofocal (yellow-tinted, UV-filtering): Marginal upgrade; not essential.
Decision framework: The medical benefit of standard vs premium IOL for cataract correction is primarily about lifestyle convenience (reading glasses or not). For most patients, standard IOL provides excellent visual outcomes. Premium IOL reduces dependence on glasses. The question is whether the OOP cost (R7,000–R20,000 per eye; up to R40,000 for both eyes with premium multifocal) is worth it for your lifestyle.
How Does Medical Aid Cover Cataracts?
| Service | PMB? | Typical cover | Notes |
|---|---|---|---|
| Ophthalmologist consultation (diagnosis) | No | Day-to-day | R1,500–R3,000/visit; shortfall likely |
| Biometry (eye measurements pre-surgery) | No | Day-to-day | Measuring eye for correct IOL power |
| Day surgery facility fee | Yes — PMB | Hospital/day procedure benefit | DSP facility |
| Surgical procedure (phacoemulsification) | Yes — PMB | Hospital benefit (PMB) | |
| Ophthalmologist surgical fee | Yes — PMB at tariff | Hospital benefit | Shortfall: gap cover relevant |
| Anaesthesiologist fee | Yes — PMB at tariff | Hospital benefit | Shortfall: gap cover relevant |
| Standard monofocal IOL | Yes — PMB | Included | Scheme tariff lens |
| Premium IOL (multifocal / EDOF / toric) | No | OOP upgrade | R5,000–R20,000 per eye |
| Post-operative drops (antibiotic + steroid) | No | Day-to-day | R300–R600 per course |
| Post-operative ophthalmologist visits | No | Day-to-day | Usually 2–3 visits |
| Second eye surgery | Yes — PMB | Separate pre-auth required | Scheme funds both eyes; pre-auth each separately |
Day-to-Day Costs: What to Budget For
| Scenario | Per eye | Both eyes |
|---|---|---|
| Standard IOL — gap cover in place | R500–R2,000 OOP | R1,000–R4,000 |
| Standard IOL — no gap cover | R15,000–R35,000 OOP | R30,000–R70,000 |
| Premium multifocal IOL — gap cover in place | R9,000–R22,000 OOP | R18,000–R44,000 |
| Premium multifocal IOL — no gap cover | R25,000–R55,000 OOP | R50,000–R110,000 |
The gap cover point is critical. Ophthalmologists commonly bill 2–3 times scheme tariff. Without gap cover, a standard cataract on one eye costs R15,000–R35,000 out of pocket despite being PMB. With gap cover, the same procedure costs R500–R2,000.
Gap Cover — Essential for Cataract Surgery
Cataract surgery is one of the clearest demonstrations of gap cover value in SA private healthcare. The procedure is PMB and heavily scheme-funded — but the ophthalmologist shortfall alone commonly reaches R10,000–R25,000 per eye. Gap cover's OPL handles this.
If cataract surgery is approaching and you do not have gap cover, get it immediately — subject to waiting periods (typically 3 months general, with no specific cataract-related waiting period unless declared as pre-existing).
Key Questions to Ask Your Scheme and Surgeon
- What is my scheme's tariff for cataract surgery, and what will the ophthalmologist charge? Ask the surgeon's rooms for a quotation letter before the procedure date.
- Is the surgical facility on the DSP panel? Most cataract surgery in SA is performed at private day clinic facilities — confirm DSP status.
- What lens does my scheme fund? Ask for the specific scheme-approved IOL.
- Is the pre-authorisation in place for both eyes separately? Each eye needs its own pre-auth.
- Has my gap cover been notified? Pre-notify for planned procedures where possible.

Cataract surgery is one of the most plannable medical events — and one where correct gap cover eliminates nearly all out-of-pocket cost. AURA helps confirm PMB entitlement, identify DSP ophthalmologists, and ensure gap cover is active before surgery.
