CHANGES IN REFRACTION AND KERATOMETRY AFTER SURGERY FOR ACQUIRED PTOSIS

A retrospective study involving 47 lids in 26 patients was conducted t o determine changes in refraction and keratometry after surgery for ac quired ptosis. Refractive and keratometric data were obtained prior to and 6 months after levator surgery. Data were analyzed for changes in refractive sphere, cylinder, and cylindrical axis, as well as keratom etry, toricity, and axis of toricity. Although patients noted subjecti ve change in vision postoperatively and demonstrated changes in their refractive error, the changes were statistically insignificant. Consis tency was noted; the cylindrical axis and the axis of toricity remaine d relatively stable after surgery.
