When residual refractive error follows cataract or refractive lens exchange surgery, surgeons may consider either:
- Intraocular lens (IOL) exchange, or
- Corneal laser enhancement
IOL exchange involves reopening the eye, with associated risks including:
- Capsular rupture
- Zonular weakness
- Cystoid macular oedema
- Retinal detachment (in susceptible individuals) ³
By contrast, corneal laser enhancement:
- Is extraocular
- Has rapid recovery
- Avoids intraocular manipulation
Multiple studies demonstrate that excimer laser enhancement after multifocal or toric IOL implantation is safe, predictable, and does not significantly worsen glare or dysphotopsia when appropriately performed ¹ ².
For small residual refractive errors (≤1.50 D), corneal refinement is often the safer and more controlled approach ².
Enhancement is frequently the logical next step, not a sign of failure, but a refinement strategy.
