The correction of diplopia after cataract extraction.

The records of 12 patients with persistent diplopia after cataract extraction were reviewed. All patients were corrected surgically using an adjustable-suture technique. After strabismus surgery, the diplopia in nine of the 12 patients resolved without adjunctive therapy. Three patients had occasional diplopia postoperatively. Prismatic correction postoperatively was unwarranted in two patients because diplopia occurred on rare occasions, but the third required postsurgical prismatic correction with improvement.
