One of the goals of cataract surgery is improving visual acuity, which is accomplished for most patients at Cole Eye Institute. Visual acuity, as measured by the ETDRS (Early Treatment Diabetic Retinopathy Study) protocol, was captured for 379 patients in 2021. There was a ≥ 15 letter improvement in ETDRS protocol refraction visual acuity in 41.95% of these patients, and 45.91% had a < 15 letter improvement.
