The world is currently facing a silent but rapidly expanding public health crisis: the myopia epidemic. According to peer-reviewed projections, an estimated 5 billion people will have myopia by the year 2050 (1). In urban environments, the prevalence is particularly alarming, with studies indicating that up to 60% of urban learners are already affected. Currently, 75% of all refractive errors are attributable to myopia.
For decades the standard response to refractive errors has been the prescription of spectacles and contact lenses. However, as the demographic of highly educated, screen-dependent professionals grows, the limitations of this conventional approach are becoming glaringly apparent. Standard optics treat the symptoms of myopia without addressing the underlying physical growth of the eye, trapping patients in a lifelong cycle of dependency.
The financial trap of conventional correction
The traditional optical benefit model is built on indefinite recurrence. Spectacles and contact lenses are consumed and renewed every one to two years, creating an escalating financial burden with no clinical endpoint. A typical contact lens and spectacle wearer in South Africa incurs an estimated ZAR 16,760 (USD 1,024) annually in recurring expenditures. This includes the cost of contact lenses (ZAR 9,600/USD 586), contact lens solutions (ZAR 2,160/USD 139), annual eye examinations (ZAR 2,000/USA 122), and prescription spectacle updates (ZAR 3,000/USA 183). Furthermore, designer frames and lens enhancements can add thousands more to this out-of-pocket expense.

When compared to the once-off cost of surgical vision correction – such as Laser-Assisted in situ Keratomileusis (LASIK) or Implantable Collamer Lenses (ICL) – the financial trajectory shifts dramatically. The break-even point for LASIK versus conventional correction is approximately three years. Over a 20-year lifecycle, a patient can realize a maximum saving of up to ZAR 295,000 (USD 18,025).

Clinical safety: The hidden risks of contact lenses
Beyond the financial implications, there is a profound misconception regarding the safety of contact lenses compared to refractive surgery. While surgery is often perceived as carrying higher risks, longitudinal clinical data proves otherwise.
A landmark 2017 study published in the Journal of Cataract & Refractive Surgery by Masters et al. (2) evaluated the risk of Microbial Keratitis (infectious corneal ulcers). The findings were definitive: while surgical risk at one year is comparable to daily contact lens wear, the long-term risks diverge sharply. Based on extrapolated five-year microbial keratitis risk estimates, daily soft contact lens wear may produce ~11 additional cases per 10 000 users compared with LASIK. Extended-wear contact lens use may produce ~ 81 additional cases of keratitis per 10 000. Risk is particularly increased with overnight wear.

Infectious keratitis is not merely a clinical complication; it is a severe, sight-threatening event that triggers multiple emergency interventions, specialist consultations, and potentially corneal graft surgeries costing healthcare funders between ZAR 5,000 (USD 305) and ZAR 30,000+ (USD 1,833) per episode. Surgical vision correction effectively eliminates this recurring infection risk profile after the initial healing phase.
Patient-reported outcomes: Insights from the Price study
To truly understand the impact of vision correction, one must look beyond clinical safety to patient-reported quality of life. Price et al.’s three-year longitudinal study provides some of the most compelling evidence to date (3). Tracking 1,800 patients over three years, the study compared visual satisfaction between LASIK patients and a control group of continued contact lens wearers.
The findings from the Price study unequivocally support the superiority of surgical intervention across several critical quality-of-life metrics.
Recommendation Rates: Patients who underwent LASIK showed a significantly higher propensity to strongly recommend their vision correction method compared to the contact lens control group over the 3-year period.
Night Driving: Post-LASIK patients consistently reported better night vision, with reduced glare and halos, resulting in clearer, sharper vision in low-light conditions—a critical factor for active professionals.
Dry Eye Resolution: Contrary to popular belief, the percentage of patients reporting no dry eye disease actually increased post-LASIK compared to their baseline while wearing contacts.
The Price study's findings on dry eye are particularly noteworthy. Contact lenses are a primary driver of dry eye disease, a condition that requires ongoing management and lubrication. Surgical correction addresses the root cause of contact lens-induced dry eye. This is further corroborated by the FDA PROWL-1 and PROWL-2 studies, which reported a 96–99% patient satisfaction rate, noting that while some patients experienced temporary dry eye at three months, the overall prevalence decreased significantly by six months post-LASIK (4).
Halting the pathology spiral
Myopia is not a static condition. In contact lens and spectacle wearers, continued wear does not prevent axial length elongation, which progressively worsens myopia over decades. Increased axial length correlates directly with higher risks of sight-threatening conditions, creating a "pathology spiral."
Long-term pathologies associated with progressive myopia include:
Myopic maculopathy: The leading cause of irreversible vision loss in high myopes, carrying a massive treatment burden.
Retinal detachments: High-risk myopes are prone to retinal tears, requiring urgent, high-cost vitreoretinal surgery.
Premature cataracts: Early-onset lens opacity necessitates earlier cataract extraction and intraocular lens (IOL) implantation.
Premature PVD (posterior vitreous detachment): Leads to ongoing monitoring costs for floaters, flashes, and increased risk of tears.
Glaucoma risk: glaucoma incidence is higher in myopia, especially in higher degrees of myopia.
Surgical correction, particularly when performed in early adulthood (ages 20–25), stabilizes the refractive error and removes the mechanical and infectious risks of lifelong contact lens wear, thereby mitigating decades of escalating secondary pathology costs.
Conclusion
The evidence is overwhelming: the current paradigm of treating vision correction as an indefinite, recurring expense is outdated. As highlighted by regulatory insights, including South Africa's Health Market Inquiry, "patients need greater transparency in healthcare. Informing patients of the options beyond glasses and contact lenses provides transparency in eye care."
For healthcare funders and health insurance providers, redirecting cumulative optical benefits toward once-off surgical correction represents a profound strategic advantage. By reclassifying FDA-reviewed, peer-validated procedures like LASIK and ICL as functional, corrective medicine rather than elective luxuries, funders can eliminate permanent liability streams associated with hardware renewals, dry eye management, and severe corneal infections.
For the patient, the transition from temporary aids to surgical correction offers a lifetime of visual freedom, superior clinical safety, enhanced night vision, and a definitive cure to the daily burden of refractive error. It is time to see clearly: surgical vision correction is not just a medical alternative; it is the definitive standard of care for the modern era.
