There are various options on proper surgical repair for blepharoptosis. We have treated 7 patients
with posterior check ligament sling and evaluated the advantages of this method from September
2006 to July 2009. These patients were blepharoptosis with moderate to severe ptosis with poor
levator function. Through the blepharoplasty incision, the upper half of tarsal plate was exposed and
the orbital septum was opened to show the levator aponeurosis. The Müller\'s muscle was dissected
from the upper border of the tarsal plate and from the posteriorly located conjunctiva. We exposed the
posterior check ligament and fixed it on approximately upper one third of the tarsal plate. We obtained
satisfactory result for more than 18 months with blepharoptosis corrected with all cases with no
significant complications: among satisfactory degrees of all blepharoptosis patients, 4 were \"Excellent\"
and 3 were \"Good\". The correction of blepharoptosis using posterior check ligament sling
showed less traumatic to levator and The Müller\'s muscle and more naturally correcting vector,
compared with other methods. Especially in patients who had insufficient correction of blepharoptsis,
the correction of blepharoptosis using posterior check ligament sling appears to be a good alternative
method.
