Figure 3

Shows statistical mean results after 3 years follow-up in G-1, G-2, and G-3, respectively (A) Shows an amelioration in CDVA (corrected distance visual acuity) (decimal), mean values in the pre-operatives were (0.40, 0.22, 0.21), at 12 months post-operatives mean values were (0.60, 0.42, 041) and (0.58, 0.40, 0.40) at 36 months post-operative. Desviation Standard = 0.151. (B) Shows an upgraded in CLDVA (decimal equivalent to logMar scale) from the pre-operative (0.61, 0.39, 0.52) until reach a maximum mean values at 36 months post-operative (0.84, 0.62, 0.75). Desviation Standard = 0.180. (C) Presents Visante CCT (central corneal thickness) (μm) mean values in the pre-operative (410, 454, 487) (μm), at 12 months post-operative, these values reached a maximum average (469, 513, 546) (μm), then at 36 months post-operative, they were established with the following average values (440, 484, 517) (μm). Desviation Standard = 62.940. (D) Presents the Scheimpflug corneal topography thinnest point (μm) mean values in the preop (385, 435, 449) (μm), there were an increase in the topographic mean values till 12 months post-operative (433, 484, 498) (μm), than at 36 months post-operative, a small decrease was obtained with this mean values (416, 466, 480) (μm). Desviation Standard = 67.966. (E) Observe the amelioration in RMS HOA (high order aberration in μm) in mean values at the pre-operative values (15.01, 10.11, 12.23), at 36 months post-operative (13.15, 8.25, 10.37). Desviation Standard = 4.530. (F) Observe Kmax , the pre-operative mean values (68, 68, 66), there was a mean values of 2 diopters more flatter at 12 months post-operative (66, 66, 64) regarding the preoperative, followed by another mean value of 1 diopter of flattening till 36 months post-operative (65, 65, 63). Desviation Standard = 8.250.
