Objective: To observe and evaluate the feasibility and clinical effect of modified combined fascial sheath (CFS) suspension on the treatment of recurrent severe blepharoptosis. Methods: A total of 26 patients (32 eyes) with recurrent severe ptosis treated in Hebei Eye Hospital from March 2017 to March 2020 were included. All patients were corrected by modified CFS suspension. The patients were followed up for 1 year, and returned to the hospital at 1 month, 3 months, 6 months and 1 year respectively. The marginal reflex distance-1 (MRD1), eyelid crease depth, length, radian, and complications were recorded as the main observation indexes and the effect was evaluated. Results: In the 32 eyes of 26 patients, 27 eyes (84.4%) were completely corrected, 4 eyes (12.5%) were improved, while 1 eye (3.1%) had no improvement, the invalid eye was adjusted again 6 months after operation, and reached the effective standard after adjustment. Conjunctival prolapse occurred in 1 case, and the symptoms of conjunctival prolapse disappeared after the treatment with drugs and pressure dressing, and no case of exposure keratitis or other complications occurred. Conclusion: Modified combined fascial sheath suspension is an effective method on the treatment of recurrent severe blepharoptosis with the advantages of simple operation, less trauma, definite therapeutic effect, and fewer complications, which is worthy of clinical promotion and application.
