Objective To study the corrective effect of severe blepharoptosis by different operation type and operation opportunity. Methods 68 patients （82 eyes） with Severe blepharoptosis at the age of 3-12 years old were randomly divided into three group, modified levator palpebrae superioris muscle resection, modified musculus frontalis flap suspension surgery and fascia lata suspension were conducted respectively. All cases were followed up 3 months to 3 years, the mean time was 6 months. Results The patients which coducted by modified levator palpebrae superioris muscle resection and modified musculus frontalis flap suspension surgery had natural appearance and satisfactory results.
