Purpose: To compare the long term results of three different procedures for correction of involutional entropion (tarsal strip, three fornix sutures, tarsal strip + three fornix sutures) among patients referred to Labbafinejad Medical Center during 1991-2001.Method: Study was performed on the hospital records of all patients with lower lid entropion who underwent surgery. Patients with less than three months of follow-up and previous operation on the same eyelid were excluded from the study. Age, gender, visual acuity, method of operation, results of operation, improvement of symptoms, and post surgical complications were reviewed.Results: During this period, 67 lids in 51 patients underwent surgery including lateral tarsal strip (LTS) in 26 lids (38.8%), three fornix sutures in 11 lids (16.4%), and the combined procedure in 30 lids (44.8%). Patients were followed for a minimum of three months and average of 6.5 months. Symptoms were epiphora, foreign body sensation, abnormal lid position, decreased vision, and burning sensation. Lid position correction rate was 88.5% for LTS, 90.9% for three sutures, and 96.7% for the combined method. Total cure (lid position and symptoms) was achieved in 76.9% of LTS cases, 72.7% of three sutures cases, and 86.6% of the combined procedures. Two cases of complications were seen, including granulation tissue formation in the lateral canthus and stitch abscess.Conclusion: The combined procedure seems to have better results in terms of symptomatic improvement and lid position than the two other procedures.
