Cataract surgery is one of the most routine, predictable, and financially manageable medical procedures in South Africa — when you know how to navigate the medical aid system. Here's how to do it right.
The Honest Starting Point
Cataract surgery is a PMB procedure, so your scheme must fund it. But "PMB-funded" means covered at scheme tariff — and private ophthalmologists consistently bill above that. Without gap cover, the shortfall alone can be R15,000–R25,000 per eye on a standard procedure. With gap cover, it drops to near zero.
Your financial preparation for cataract surgery should begin with confirming gap cover is in place.
Step 1: Confirm Clinical Indication — When Is the Right Time?
Cataract surgery is indicated when: - Vision loss is affecting daily activities (reading, driving, watching TV) - Best-corrected visual acuity has declined significantly despite updated glasses - Glare and halos from cataracts are impairing safe driving at night
There is no single "right" visual acuity threshold — the decision is clinical and functional. Your ophthalmologist assesses both eyes and recommends which to operate first (usually the worse eye).
Ask your ophthalmologist: "Are my cataracts affecting my functional vision enough to justify surgery, and will you document this clearly in the pre-authorisation request?"
Step 2: Pre-Authorise Each Eye Separately
Before booking surgery, your ophthalmologist's rooms submit a pre-authorisation request to your scheme for each eye. Each eye requires a separate authorisation number.
What the pre-auth request should include: - Ophthalmologist's clinical assessment and vision measurements - Evidence of functional impairment - Proposed surgical procedure and standard IOL specification
Your scheme's managed care company (ophthalmic case manager in larger schemes) reviews and approves. Standard uncomplicated cataracts are almost universally approved.
Ask the surgeon's rooms: "Has pre-authorisation been confirmed for both eyes, and do you have authorisation numbers for both?"
Step 3: Sort Out the Lens Decision in Advance
Before the surgery date, your ophthalmologist will perform biometry (measurements of your eye) to determine the correct IOL power. At this consultation, the IOL options will be discussed.
Your decision:
Standard IOL (scheme-funded): Appropriate for most patients. Excellent distance vision; reading glasses needed. The right choice if OOP budget is a concern, or if you already use glasses and are comfortable continuing to do so.
Premium multifocal or EDOF IOL (OOP upgrade): Reduces dependence on reading glasses. Worth considering if you do a lot of close work without glasses and find the prospect of reading glasses inconvenient. Costs R7,000–R20,000 per eye above the scheme contribution.
Toric IOL (OOP upgrade, if significant astigmatism): Corrects astigmatism alongside cataract. Reduces need for prescription spectacles post-operatively.
Key rule: Do not be upsold on a premium lens without a clear explanation of the clinical benefit for your specific case. Ask: "What specific visual benefit will the premium lens give me compared to the standard lens, and what is the total OOP cost?"
Step 4: Get a Written Quotation Before Surgery Day
Ask the surgeon's rooms for a written quotation that includes: - Surgeon fee and scheme tariff amount - Expected shortfall (surgeon fee minus scheme tariff) - Anaesthesiologist estimated fee (if applicable) - IOL cost (standard scheme-funded vs any premium upgrade you've chosen) - Facility fee (if day clinic is non-DSP)
This prevents surprise billing.
Step 5: Notify Gap Cover Before Admission
Contact your gap cover provider at least 1 week before the surgery date: - Pre-notify the procedure - Confirm the procedure (cataract extraction, IOL implantation) is covered under your policy - Confirm the surgeon and facility are covered - Get a pre-notification reference number
Most gap cover providers have an online pre-notification system or a simple phone process.
Step 6: Post-Operative Care
After cataract surgery: - Follow your ophthalmologist's post-operative drop regimen exactly (antibiotic + steroid drops — typically 4 weeks) - Attend all post-operative follow-up appointments (typically day 1, week 1, week 4) - Post-operative drops and follow-up visits are funded from your day-to-day benefit
If you have diabetes, ensure blood sugar is well-controlled before and after surgery — poor glycaemic control significantly impairs healing and increases infection risk.
Bilateral Cataracts — Timing the Second Eye
Most patients have bilateral cataracts. Surgery is typically performed on the worse eye first; the second eye follows 4–8 weeks later once the first has healed and the outcome is assessed.
For the second eye: Your ophthalmologist's rooms submit a second pre-authorisation. Do not assume the first authorisation covers both — it does not. Confirm the second pre-auth is in place before booking the second procedure date.
Gap cover: Pre-notify the second procedure separately. Both procedures in the same policy year count against your OPL — confirm your annual limit is sufficient.
