Design: retrospective observational non-comparative study. Methods: 13 eyes (8 patients) had developed late onset DLK-like reaction after uneventful LASIK procedure. The patients were divided into 2 groups, group I (GI):展开更多

Preoperatively, uncorrected distance visual acuity (UCDVA), best-corrected distance visual acuity (BCDVA), central corneal thickness(CCT) and average keratometry (Av-K) were measured and compared with post-operative results at one week, one month, three months, and six months. ·RESULTS:Mean preoperative UCDVA and BCDVA were (1.32±0.31) logMAR and (1.07±0.27) logMAR, respectively. Av-K was (52.13±0.39)D, and the CCT was (432±39.5)μm. Post-operative examinations showed a clinically significant improvement in both UCDVA and BCDVA (P <0.001). There was also a significant effect based on the time of assessment on both UCDVA and BCDVA and both parameters had a continuous improvement during the follow-up period. Three months after operation there was a statistical significant reduction of Av-K (P =0.0001), but there were no significant changes in CCT (P =0.149). ·CONCLUSION:Intacs SK corneal ring segment implants seem to be a safe and effective treatment option for patients who have keratoconus, clear central cornea, and contact lens intolerance.展开更多
