Looking for a category-level comparison instead of a single model? Start with IOL Options to understand the broad categories — monofocal, enhanced monofocal, EDOF, and full-range/trifocal — before drilling into individual models here.
IOL Model Reviews
Model-by-model reviews built from FDA records and peer-reviewed studies. I look for the result that changes a decision: a real benefit, a target the study did not meet, a symptom rate or a gap the brochure does not answer.

Reviewed lenses
Tecnis Eyhance Review
An enhanced monofocal lens designed to add intermediate range to a standard monofocal's clarity.
enVista Aspire IOL Review
A sensible enhanced-monofocal design, but its headline gains rely on internal and model-eye data; the main clinical study has 29 eyes and no control.
TECNIS Symfony Review
A diffractive EDOF lens reviewed from its FDA trial and randomized comparative evidence — including intermediate range, spectacle use and night symptoms.
TECNIS PureSee Review
A newer non-diffractive EDOF lens from J&J — reviewed using its FDA registration study data, with source-cited charts.
TECNIS Synergy Review
J&J's diffractive extended-range lens — strong spectacle independence alongside a meaningfully higher halo/glare rate, per its FDA data.
Alcon PanOptix Review
A widely used trifocal IOL aiming for distance, intermediate, and near vision without glasses — reviewed from its FDA registration data.
Alcon Vivity Review
A non-diffractive EDOF lens positioned between enhanced monofocal and full presbyopia-correcting designs — including a trial target it didn't meet.
TECNIS Odyssey Review
J&J's newest full-range IOL — reviewed from independent peer-reviewed studies, since no FDA SSED is yet published for this lens.
Monofocal lens reviews
Model-by-model looks at standard single-focus lenses, the most established IOL category.

enVista Aspire: what the new 141-eye study tells us—and what it does not
A closer look at Aspire outcomes in 141 eyes: the people behind “100%”, missing comparison groups, testing distances and the current safety wording.

TECNIS Odyssey: good near-to-far vision—but what do the halo numbers really mean?
Odyssey clinical studies reviewed: why noticing halos differs from bother, what contrast tests measured and where comparisons with other IOLs remain limited.

How IOLs Are Tested in the Lab — and Why Bench Tests May Not Show the Whole Picture
How optical-bench tests measure IOLs, what ISO2 and ACE model eyes mean, and why MTF results cannot by themselves predict a patient’s vision.
