If this is a medical emergency involving sudden vision loss, call 10177 or go to the nearest emergency room immediately.
Routine cataract surgery is a planned procedure, but eye emergencies can arise in cataract patients — and some conditions mimic cataracts with far more urgency. This article covers urgent scenarios.
When Vision Problems Are a Genuine Emergency
Not all vision loss is cataract-related. The following are eye emergencies requiring immediate ER or ophthalmology assessment:
| Symptom | Possible cause | Action |
|---|---|---|
| Sudden complete loss of vision in one eye | Central retinal artery occlusion ("eye stroke") | ER immediately — window for treatment is minutes |
| Curtain-like shadow or floaters + flashes | Retinal detachment | Urgent ophthalmology today — do not delay overnight |
| Severe eye pain + redness + nausea + halos around lights | Acute angle-closure glaucoma | ER immediately — sight-threatening emergency |
| Sudden double vision | TIA/stroke, cranial nerve palsy | ER immediately — may indicate stroke |
| Eye pain + redness + discharge after cataract surgery | Post-operative endophthalmitis | Contact your surgeon immediately; ER if unavailable |
None of the above is routine cataract progression. If you experience any of these, do not assume "it's just the cataracts getting worse" — get assessed immediately.
Post-Operative Emergencies After Cataract Surgery
Endophthalmitis (Post-Operative Eye Infection)
Endophthalmitis is a rare but devastating infection inside the eye that can cause permanent blindness within hours to days if untreated. It typically occurs 1–7 days post-surgery.
Symptoms: Rapid deterioration in vision, increasing pain and redness, eye discharge, photophobia.
Action: Contact your ophthalmologist immediately. If unavailable, go to the nearest ER with ophthalmology. This is a sight-threatening emergency requiring same-day intervention (intravitreal antibiotics, possibly vitrectomy).
PMB coverage: Post-operative endophthalmitis requiring emergency treatment is PMB — covered as an emergency complication of a PMB procedure.
Posterior Capsule Rupture or IOL Dislocation
Rare surgical complications that may require return to theatre. Funded under the original PMB procedure or as a new in-hospital procedure.
Raised Intraocular Pressure (Post-Operative)
Moderate IOP elevation post-cataract surgery is common and usually transient. If you have severe eye pain and very high IOP confirmed at a follow-up visit — your surgeon will manage this with pressure-lowering drops. Sustained high IOP post-cataract surgery requires urgent ophthalmology follow-up.
If Your Pre-Authorisation Is Declined
If your scheme declines pre-authorisation for cataract surgery:
- Request written reasons.
- The most common grounds for decline: "vision not impaired enough to meet PMB criteria." This is a clinical judgement call.
- Your ophthalmologist should submit a stronger clinical motivation:
- Best corrected visual acuity measurements for both eyes
- Functional impairment documentation (unable to drive safely, difficulty reading, failing occupational eyesight standards)
- Comorbidities that make cataract progression particularly high-risk (e.g., diabetes-related cataract)
- Internal appeal with the ophthalmologist's supporting notes.

Disputing an Unexpected Post-Surgery Bill
If your bill is significantly higher than quoted:
- Request itemised accounts from the surgeon, anaesthesiologist, and facility separately.
- Confirm what your scheme paid (call the scheme for the Explanation of Benefits statement).
- Confirm gap cover has processed the claim.
- If you were charged for a premium IOL you didn't consent to: challenge the surgeon's rooms directly with your written pre-operative consent.
- Consumer Commission for billing disputes: contact the Health Professions Council of SA (HPCSA) or the CMS for guidance on billing dispute resolution.
Sudden Vision Deterioration After Successful Surgery
If your vision begins to deteriorate months or years after successful cataract surgery:
Posterior capsule opacification (PCO): The most common late complication — the posterior capsule behind the IOL becomes cloudy, mimicking a new cataract. Treated with a quick, painless laser procedure (YAG capsulotomy) in the ophthalmologist's rooms. Fully PMB-covered (same DTP). Requires new pre-authorisation.
