SAN DIEGO Patients undergoing combined vitrectomy and scleral buckling surgery have a higher risk of developing cataracts than those undergoing either surgery alone, according to a group of researchers.
In a poster presentation here at the American Society of Cataract and Refractive Surgery meeting, R.I. Huffman and colleagues reviewed the medical records of phakic patients who underwent vitrectomy alone, scleral buckling alone or both procedures combined, between January 1998 and December 2002.
Of 40 patients who underwent vitrectomy alone, mild postop cataract (defined as a change in severity of 1+) developed in 22 patients (55%). In 18 patients who underwent scleral buckling alone, mild postop cataract developed in two patients (11%). In 12 patients who underwent a combined procedure, 11 (92%) developed mild postop cataract.
Moderate postoperative cataract (a change in severity of 2+) developed in 14 of 40 eyes (35%) after vitrectomy alone, in one of 18 eyes (5%) after scleral buckling surgery alone and in eight of 12 eyes (67%) after a combined procedure.
