There are several methods for blepharoptosis correction. Many complication of blepharoptosis induced by operation. Lid lag and lagophthalmos is especially, a difficult problem to resolve. So, many plastic surgeons make an effort to prevent lid lag or lagophthalmos. One of blepharotposis correction methods, we have used Mller's muscle tucking method since 2004. The author's method is Mller's muscle tuck with fixation to the tarsal plate and pretarsal fascia with nylon #6-0 and aponeurosis sutured with pretarsal orbicularis muscle or pretarsal area dermis. We have found this method to show good results, with resulting no or only mild lagophthalmos than previous ptosis corrective methods. This method yield results with more post-operative predictability than aponeurosis surgery due to preservation of the aponeurosis gliding plane. If this method is applied to mild and moderate ptosis, it is one of good method of ptosis correction.
