ETDRS Vision Improvement

2017 – 2019

One of the goals of cataract surgery is improving visual acuity, which is accomplished for the vast majority of patients at Cole Eye Institute. Visual acuity, as measured by the ETDRS (Early Treatment Diabetic Retinopathy Study) protocol, was captured for 1,440 patients in 2019. There was a ≥ 15 letter improvement in ETDRS protocol refraction visual acuity in 43.19% of these patients, and 47.01% had a < 15 letter improvement. The remaining 9.79% had no change or a decrease from baseline status.
