AIM: To investigate the efficacy of autologous serum combined with recombinant human epidermal growth factor in repairing of corneal defect after corneal foreign body eliminating operation.

METHODS: Totally 92 patients with corneal foreign body(110 affected eyes)as the research object in our hospital from October 2015 to March 2016. All the patients were divided into the treatment group and the control group according to the random number table. There was no significant difference between the two groups in age, sex and disease course. Both groups received corneal foreign body elimination by slit lamp. The treatment group was given eye drops containing epidermal growth factor combined autologous serum and tobramycin after surgery, while the control group was only administrated with epidermal growth factor and tobramycin. Treatment effects were compared 1wk after treatment.

RESULTS: One week after the treatment, the cure rate in the treatment group(96.4%)was much higher than that in the control group(78.2%). Two days after treatment, the fluorescein staining in the treatment group was 98.2%, it was higher than that in the control group(83.6%). The concentration of TNF-α and IL-6 of the treatment group was lower than that in the control group. One week after the treatment, AS-OCT images showed that the repair of corneal matrix in the treatment group was closer to the preoperative normal level.

CONCLUSION: The treatment effect that AS combined rhEGF is much better than that only usde rhEGF, shortened healing time of corneal epithelial wound. It is more effective and security to treat traumatic corneal epithelial defect, better repair function to corneal matrix.
