Under-flap stromal bed CXL for early post-LASIK ectasia: a novel treatment technique.

Cylinder vector analysis Cylinder vector analysis revealed a nonsignificant trend toward overcorrection post-ufCXL compared with pre-ufCXL ( Figure 4A , Correction Index: 1.10±0.67 vs. 0.83±0.33, respectively; P =0.44) and an increased index of success (IOS) post-ufCXL compared with pre-ufCXL (IOS: 0.86±1.12 vs. 0.58±0.52, respectively; P =0.45).
