UDVA = uncorrected distance visual acuity; CDVA = corrected distance visual acuity; UNVA = uncorrected near visual acuity; CNVA = corrected near visual acuity; TCA = total corneal astigmatism; SIA = surgically induced astigmatism; AE = angle of error; = comparison between pre-op and post-op and was considered statistically significant; = comparison of both groups and was considered statistically significant.
