Changes in Intraocular Pressure after Transepithelial Photorefractive Keratectomy and Femtosecond Laser In Situ Keratomileusis

Figure 2

Box plot of biomechanically corrected intraocular pressure (bIOP) changes from before surgery to 1 month after transepithelial photorefractive keratectomy (TPRK) and femtosecond laser in situ keratomileusis (FS-LASIK). The bottom and top of each box represent the lower and upper quartiles, respectively. The line inside each box represents the median. The bars represent data within 1.5 times the interquartile range. Reductions in bIOP after FS-LASIK were 1.64 mmHg more than those after TPRK, after adjusting for confounders.
