Figure 2

Graph demonstrating the logarithm of the minimum angle of resolution (logMAR) uncorrected visual acuity (UCVA) in eyes with myopic regression after laser in situ keratomileusis in the 2 treatment groups in different follow-up visits. Before treatment with eye drops (pretreatment), the difference in the mean logMAR UCVA was not statistically significant between the 2 groups (P = .667, independent samples t test). Three months after the twice-daily application of Timolol (during treatment), the mean logMAR UCVA decreased significantly in Group 1 (from 0.17 pretreatment to 0.04 during treatment, P = .000, n = 32, one-way ANOVA test) and gained 0.19 lower than the mean logMAR UCVA in Group 2 (P = .000, independent samples t test). Two months after cessation of Timolol treatment (posttreatment), the mean logMAR UCVA in Group 1 increased significantly (from 0.04 during treatment to 0.12 posttreatment, P = .016, n = 32, one-way ANOVA test) and almost returned to its own pretreatment level (0.17, P = .122, n = 32, one-way ANOVA test). But it still was significantly lower than the mean logMAR UCVA in Group 2 (P = .002, independent samples t test). ANOVA = analysis of variance, logMAR = logarithm of the minimum angle of resolution.
