[Abstract] Objective This paper tries to explore the therapeutic effect of clinical application of keratoconus corneal collagen crosslinking. Methods 41 patients with keratoconus were convenient selected in this hospital from May 2015 to May 2016, were given cross-linking of corneal collagen treatment, the treatment effect was observed. Results ①The symptoms of discomfort were: intraoperative (2.93±0.58)points, postoperative 1 d (2.71±0.62)points, postoperative 3 d (1.53±0.67)points, postoperative 1 week (0.38±0.47)points, postoperative 1 month(0.30±0.31)points; 3 d after surgery, 1 week after surgery, 1 month after surgery was lower than intraoperatively and 1 day after operation, and 1 week after operation and 1 month after operation were lower than 1 day after operation(t=6.147, 6.338, 6.534, 7.264, 7.301, P<0.05). ②the last follow-up,19.5% uncorrected visual acuity, 24.4% best corrected visual acuity increased more than 2 lines. ③The preoperative values of SmiK (6.08±3.61), Kmin (47.08±2.34), central corneal thickness (468.23±28.91) μm, thinnest corneal thickness(447.82±31.82) μm and corneal endothelial cells(2 798.17±272.07)mm2, ofter 1year Simk(5.51±3.07),Kmin (46.87±2.49), the central corneal thickness(467.15±24.65)μm, the thinest corneal was (439.05±35.78)μm, the corneal endothelial cells(2816.63±279.76)mm2(t=0.528,0.824,0.647,0.627,0.539, P>0.05);preoperative Kmax (54.28±4.22), 1 year after surgery Kmax (52.67±4.62)(t=6.301,P=0.015). Conclusion The application of keratoconus corneal collagen crosslinking treatment has good treatment effect, which can effectively improve the cornea and visual acuity in patients.

青少年为圆锥角膜高发人群,双眼通常会先后进行性发病,疾病进展具有渐进性,可在任何年齡终止,形成瘢痕,显著减退视力[1]。目前,临床上存在较多的治疗圆锥角膜的方法,但多数方法仅能将屈光不正纠正,无法对病情进展做出有效的阻止。近几年研究指出,角膜胶原交联法,即紫外线A照射与核黄素联合治疗法在圆锥角膜治疗中能够获得较好的治疗效果。因此,该院在2015年5月—2016年5治疗41例圆锥角膜患者时,即采用角膜胶原交联法,疗效较理想,现报道如下。
