The use of bank sclera to correct lid retraction.

Twenty-two scleral grafts were inserted in patients with retracted lids, the youngest patient was two years old at time of surgery. Two patients were operated on under local anaesthesia and the remainder under general anaesthesia. In the patients with thyroid disease larger grafts were required, the temporal side of the graft being 3 mm greater vertically than the nasal. Our first cases were undercorrected, so we used grafts of a size at least twice that required to lower the lid. Other complications were rare. For ptosis overcorrections, and congenital lid retraction, the graft should be 2 mm bigger horizontally and vertically than the amount required to lower the lid.
