Note: some visual acuities were converted to logMAR using the visual acuity conversion chart prepared by Jack T Holland.
BDCNVA, best distance corrected near visual acuity; CLE, clear lens extraction; CS, contrast sensitivity; FDA, Food and Drug Administration; HOA, high order aberration; LogMAR, log minimum angle of resolution; logRAD, logarithm of the reading acuity determination; UCDVA, uncorrected distance visual acuity; UCIVA, uncorrected intermediate visual acuity; UCNVA, uncorrected near visual acuity.
