BCVA = best corrected visual acuity; DBCVA= difference in best corrected visual acuity (LogMAR units); LogMAR = logarithm of the minimum angle of resolution; n = number. The last column reports the p-value of the t-test of the difference between Single Peel and Double Peel. P-value < 0.05 was determined as statistically significant.
