Abstract: Objective To investigate the use of corneal bandage lens(CBL)on postoperative complications after strabismus surgery. Methods Randomized This randomized pilot study involved 60(60 eyes)patients requiring strabismus surgery, who were randomly divided into two groups: CBL(30 patients, 30 eyes)and control(30 patients, 30 eyes). The CBL group was treated with CBL after strabismus surgery, whereas the control group was treated with strabismus surgery alone. The pain, ocular surface irritation symptom, corneal dellen(CD), and conjunctival granuloma(CG)scores at postoperative days 1, 2, 7, and 14 were observed and analyzed. Tear break-up time(BUT)and corneal fluorescein staining score(CFSS)at postoperative days 7 and 14 were also observed and analyzed. Results Pain and ocular surface irritation symptom scores at postoperative days 1 and 2 were significantly lower in the CBL group than in the control group, with no statistically significant difference at postoperative days 7 and 14. CFSS was evidently reduced at postoperative day 7 and BUT was significantly increased at postoperative days 7 and 14 compared with those of the control group, but CFSS had no statistically significant difference at postoperative day 14. Postoperative complications included two cases of CD at postoperative day 7 and one case of CG at postoperative day 14 in the control group, while these postoperative complications were not observed in the CBL group. Conclusion The use of CBL after strabismus surgery significantly relieved postoperative pain and irritation ocular surface, decreased CD and CG postoperative complications, relieved the symptoms and signs of dry eyes, and finally improved patients’comfort and satisfaction.
