Anterior Versus Posterior White Line Advancement Technique in the Correction of Aponeurotic Ptosis

This technique involves a skin incision at the eyelid crease, dissection through the orbicularis muscle to expose the tarsus, and proximal dissection in the pre-Müller-conjunctival plane to visualize the white line. A double-armed 5-0 absorbable suture is used to advance the white line to the anterior tarsal surface. Eyelid height and contour are assessed before final fixation. Skin closure is completed with a non-absorbable suture.

This conjunctival technique uses a traction suture and eyelid eversion to access the posterior surface of the eyelid. A conjunctival incision is made above the superior tarsal border, followed by dissection to expose the white line. A double-armed 5-0 absorbable suture is passed through the anterior tarsus and the white line, and tied after confirming adequate eyelid position. The conjunctiva is not sutured.
