Graph demonstrating the spherical equivalent (SE) 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 SE was not statistically significant between the 2 groups (P = .442, independent samples t test). Three months after the twice-daily application of Timolol (during treatment), the mean SE increased significantly in Group 1 (from −1.21 D pretreatment to −0.58 D during treatment, P = .000, n = 32, one-way ANOVA test) and gained 1.04 D higher than the mean SE in Group 2 (P = .000, independent samples t test). Two months after cessation of Timolol treatment (posttreatment), the mean SE in Group 1 decreased significantly (from −0.58 D during treatment to −0.90 D posttreatment, P = .043, n = 32, one-way ANOVA test), but it still significantly was higher than its own pretreatment level (−1.21, P = .038, n = 32, one-way ANOVA test) and than the mean SE posttreatment in Group 2 (P = .000, independent samples t test). ANOVA = analysis of variance.
