ABSTRACT
@#AIM:
To analyze the effectiveness of transepithelial-corneal collagen cross-linking for 1a after the treatment of progressive keratoconus and discuss its clinical significance. <p>METHODS:
A total of 45 cases(48 eyes)of progressive keratoconus who underwent accelerated transepithelial-corneal collagen cross-linking in our hospital from Jan. 2017 to Dec. 2018 were collected. After 1a of postoperative follow-up, the changes of visual acuity, corneal thinnest point thickness, corneal endothelial cell count, corneal cross-linking line depth, Km of anterior corneal curvature and corneal biomechanical parameters before and after surgery were analyzed.<p>RESULTS:
Compared with preoperative, the uncorrected visual acuity(UCVA)was improved obviously postoperative in this group patients(<i>P</i><0.05), but the best-corrected visual acuity(BCVA), corneal thinnest point thickness and corneal endothelial cell counts were no significant change(<i>P</i>>0.05). At 6mo and 1a postoperative, Km of anterior corneal curvature(48.54±2.57, 48.77±2.29D)are decreased significantly, the first flatten width of corneal biomechanical parameters(1.52±0.21, 1.57±0.22mm)were significantly lower(<i>P</i><0.05). The absolute value of the second flattening velocity(0.82±0.09, 0.82±0.18m/s)was significantly increased(all <i>P</i><0.05).<p>CONCLUSION:
Accelerated transepithelial-corneal collagen cross-linking surgery for progressive keratoconus can significantly improve the UCVA and corneal biomechanics postoperative, but the BCVA was not significantly improved.
