Abstract： To the Editor:Blepharoptosis is a disease commonly seen in the Asian population,defined as an abnormal lower upper eyelid margin that is ＜2.0 mm above the midpoint of the pupil when a person looks straightforward.Surgical corrections are often needed because severe blepharoptosis may cause visual problems such as visual field compromise,hindered vision,or even amblyopia.For mild-to-moderate ptosis with levator function over 5 mm,various surgical procedures can be applied,such as the Müller muscle conjunctival resection,shortening of the levator palpebrae,or levator muscle advancement.However,most of these procedures may cause common complications such as overcorrection or undercorrection.Hence,we came up with a modified surgical procedure to fix the mild-to-moderate ptosis,while overcorrection and other complications were rarely observed.
