Many surgeons afraid to carry out this operation because of the fear caused by inner canthal scar . Park Act , inner canthus ligament shortening and double eyelid surgery the same period . Through clinical validation of this method is satisfied with the corrective effect of all types of epicanthus . Methods : self- admitted from 2007 to 2009 , 125 cases of patients with epicanthus upper eyelid type 48 cases , 52 cases of a total of 96 side , meibomian , 104 sides , lower eyelid 25 cases , a total of 50 sides , age 20 -40 years old , with an average age of 30 years old .

Results: After 4-6 months follow-up of 125 patients telephone : 125 patients caruncle revealed moderate , inner canthal distance narrows double eyelid line with inner canthal incision natural convergence .
