Abstract Details


To identify current and emerging non-IOL approaches to the presbyopic patient. Corneal, lenticular and scleral approaches will be presented along with the clinical results to date.


Literature Review & Retrospective Cohort


A literature review was used to identify papers related to the correction of presbyopia. IOL-based solutions were excluded and the remaining papers were screened for the nature of the approach and the clinical data on the approaches to date.


There are a number of promising non-IOL approaches to addressing presbyopia. Intracor, presbyLASIK and corneal inlays involve changes to the cornea, producing multifocality or increased depth of field (through high asphericity or small aperture effects). Challenges include preserving best distance corrected vision, appropriate surgical alignment and broad application. One lenticular procedure has demonstrated feasibility but limited effectiveness. Two scleral procedures take different approaches, one involving implants while the other employs micro-excisions. These latter three procedures are designed to attempt restoration of accommodation in presbyopic patients. Most recent results will be presented.


A number of non-IOL alternatives are under investigation for treating presbyopia. Corneal techniques have demonstrated some efficacy, but with unwanted visual disturbances. Lenticular techniques have not yet demonstrated consistent efficacy. Scleral techniques are appealing because they avoid the visual axis but more compelling clinical data are required for demonstrating efficacy.
