机译：Objective: To observe the clinical effect of 20% deproteinized calfblood extract eye gel on the treatment of mechanical injury to corneal epithelium. Methods: 120 cases of patients with corneal epithelial defect caused by mechanical injury were selected and randomly divided into observation group (60 eyes, deproteinized calfblood extract eye gel in use) and control group (0.3% ofloxacin eye drops in use). Both two groups of patients were given eye gel or eye drops 4 times per day. Moreover, the two groups of eye symptoms and corneal epithelial healing were observed on the 3rd day and the 7th day after drug usage respectively. Results: The effective rates of 20% deproteinized calfblood extract eye gel on the treatment of mechanical corneal epithelial defect on the 3rd day and the 7th day were 78.33% and 93.33% respectively. Meanwhile, the effective rates of 0.3% ofloxacin eye drops were 55.00% and 71.67%. The difference in the comparison of the effective rate between two groups was of statistical significance (p < .05). Conclusions: 20% deproteinized calfblood extract eye gel can significantly promote the healing of corneal epithelium in a short time, and it is worthy to be widely applied clinically.
