Paired sample t-test. †One-way analysis of variance. ‡Fisher’s least significant difference (LSD) post-hoc test. ¶Bonferroni post-hoc test. #The average of Shaffer classification recorded in the superior, inferior, nasal, and temporal quadrants. OP = operation, IOP = intraocular pressure, VA = visual acuity, SE = spherical equivalent, D = diopters, ACD = anterior chamber depth, AL = axial length, VCD = vertical cup versus disc, No. = number, and SD = standard deviation.
