Postcataract extraction ptosis: effect of the bridle suture.
Postcataract extraction ptosis is a common complication of cataract surgery. While many factors have been implicated in its etiology, trauma to the superior rectus/levator complex is considered the most important factor. We prospectively evaluated the effect of two superior rectus bridling techniques on the degree and severity of ptosis present three months after cataract surgery. All other potential variables were controlled for. Bridling the tendon of the superior rectus muscle using the direct, subconjunctival (open) approach results in significantly less severe ptosis than the standard technique of indirect transconjunctival (closed) bridling.
