Objective:

Argue that low uptake of eligible eye surgery may reflect barriers in the patient journey and practice systems, rather than limitations in clinical technology.

Approach:

• Adoption figures: The article cites estimates for premium IOL, toric IOL, and laser refractive surgery uptake to illustrate that many eligible patients have not undergone surgery.
• Constraint framework: It applies Eliyahu Goldratt’s Theory of Constraints to the patient journey, from awareness through surgery, and outlines five steps: identify, exploit, subordinate to, and elevate the constraint, then repeat.

Key Findings:

• Market Scope projected premium IOLs would account for just under 17% of global units in 2025; toric lenses were reported in 6%–8% of cataract procedures, despite an estimated 52%–70% of cataract patients qualifying.
• One analysis estimated that 3.6% of eligible people in the UK had received refractive surgery after a decade at peak volume; the article reports uptake of about 13% in the US.
• The 2015 ASCRS Clinical Survey identified patient cost as the leading barrier to presbyopia-correcting IOL adoption, followed by concern about nighttime vision quality.
• David Harmon of Market Scope reported that about 25% of cataract surgeons offered neither presbyopia-correcting nor toric IOLs.

Interpretation:

The article argues that awareness, perceived value, patient expectations, and practice-level confidence or sales skills may constrain adoption. It proposes measuring where eligible patients are lost and addressing that bottleneck before investing in other areas.

Limitations:

• The article presents selected estimates and survey findings but does not provide full study methods or citations.
• The proposed patient-journey framework is an argument, not a reported comparative evaluation of interventions.

Conclusion:

The author contends that increasing surgery uptake may depend on identifying and addressing barriers in the patient journey, alongside continued clinical advances.
