PresbyLASIK

PresbyLASIK is a corneal refractive procedure intended to correct presbyopia by creating a multifocal corneal surface. Using an excimer laser, the cornea is reshaped to provide both distance and near vision, potentially reducing dependence on reading glasses for many tasks.

Several approaches exist. Multifocal presbyLASIK creates distinct distance and near zones on the cornea, while monovision-presbyLASIK targets one eye for distance and the other for near or intermediate vision. Wavefront-guided or aspheric treatments are used to preserve quality of vision; some methods employ a LASIK flap, others use surface ablation.

Candidates are presbyopic adults typically aged 40 to 60 who want reduced glasses dependence and have stable refraction for 6 to 12 months. Adequate corneal thickness and good ocular surface health are needed. Exclusion criteria include very high refractive errors, irregular corneas, dry eye, glaucoma, cataracts, or keratoconus.

The procedure is usually performed under topical anesthesia and takes a short time. Recovery can include mild discomfort and fluctuating vision for days to weeks; most patients gain functional near and distance vision, though some still rely on reading glasses for fine print.

Risks include glare or halos at night, reduced contrast sensitivity, dry eye symptoms, infection, regression of effect, or dissatisfaction with near vision. Outcomes vary and are less predictable than standard monofocal LASIK.

Alternatives include monovision contact lenses, conventional LASIK with monovision, or other presbyopia-correcting options such as presbyopic corneal inlays or multifocal IOLs during cataract surgery.
