METHODS: Thirty-one eyes of 22 keratoconus patients with at least 12 mo follow-up were recruited and reviewed retrospectively. Uncorrected visual acuity (UCVA), best spectacle corrected visual acuity (BSCVA), autorefractometer values, keratometric values, corneal irregularity indexes, and complications were analyzed pre- and post-operatively. RESULTS: At the last follow-up visit, mean UVCA (logMAR) improved significantly from 0.86±0.34 to 0.30±0.29 (P<0.0001), and mean BSCVA (logMAR) improved from 0.47±0.21 to 0.17±0.23, (P<0.0001). Mean keratometric values decreased from 48.69±3.68 to 44.33±3.09 diopters (P<0.0001). Mean spherical equivalent measured by autorefractometer was also improved significantly from -5.61±2.85 to -2.29±1.95 at the last follow-up visit (P<0.0001). Central corneal thickness and corneal irregularity index of 3 mm and 5 mm zones did not change during the overall follow-up time. No serious intraoperative or postoperative complication was observed. CONCLUSION: RK is assessed as an effective treatment method for the optical and visual rehabilitation of mild to moderate keratoconus cases, according to our results in a selected group of keratoconus patients.?? ??:?????????????????????? ?????????? ??:?????????????????????? ?? 22 ? 31 ??????? 12mo ???? ????? ????????,??????,??????,??? ?,????????????? ??:????????,??????(logMAR)? 0. 86? 0. 34 ????? 0. 30?0. 29 (P<0. 0001),?????? ??? 0. 47?0. 21 ??? 0. 17?0. 23(P<0. 0001)? ?? ????? 48. 69 ? 3. 68D ??? 44. 33 ? 3. 09D ( P < 0? 0001)? ???????????????-5. 61 ?2. 85D ?????-2. 29?1. 95D(P<0? 0001)? ????? ???,??????? 3mm,5mm ????????? ?????? ???????????????? ??:??????,??????????????? ????????????.eninfo:eu-repo/semantics/openAccessKeratoconusOptical RehabilitationRadial Keratotomy????????????????Article15457257610.3980/j.issn.1672-5123.2015.4.02Q4
