(FIGURE 3) A. Preoperative Pentacam tomography reveals inferocentral steep cone (Kmax: 53.10 D) (Rx: –0.50 –2.00@135, CDVA 20/20) B. One-year following AP/OS, the Pentacam shows superior steepening Kmax: 47.2 D with a reduced inferocentral reading K: 43.50 D. Rx: +1.00 –0.75@140 CDVA: 20/32, UCDVA: 20/40 C. At 4 years postoperatively, Pentacam reveals an inferocentral flattening K:39.30 D while the superior corneal power remains stable Kmax: 46.70D. Rx: +1.50 –2.25@135 CDVA: 20/32, UCDVA: 20/40 D. At 10 years postoperatively, the inferocentral corneal power shows flattening Kmin: 34.80 D, meanwhile the superior Kmax readings are 46.60 D. Rx: +4.75 –1.75@75 CDVA: 20/50, UCDVA: 20/63.
