両眼開放（僚眼固視）による白内障手術

Cataract surgery with both eyes open with the fellow eye used for fixation

　手術眼の眼位を安定させ，安全に手術をするために，両眼開放で白内障手術を128眼83例に行った。僚眼で視標を注視させ，手術は，点眼麻酔，結膜下麻酔，テノン嚢内麻酔のいずれかで行った。視標は，鏡に映したテレビ，印刷した画像，小型液晶テレビのいずれかを眼前30cm以上の位置に置いたが，手術中の眼位はこの順で安定していた。この両眼開放下での白内障手術は，手術中の眼位が安定し，手術操作が円滑に行え，患者の不安感と緊張を和らげる効果があった。

We performed cataract surgery on 128 eyes of 83 patients. During surgery, both eyes were kept open with the fellow eye used for fixation. The fixation target was placed 30 cm or more before the fellow eye. Surgery was performed either under instillation, tenon capsule or subconjunctival anesthesia. Three types of fixation target was used : a television screen reflected by a mirror, small liquid crystal color television, and a printed picture. The eye position during surgery remained more stable in the above order. The present surgical method had the merit in stabilizing the eye position during surgery, smoother operative procedures, and in eliminating anxiety and stress of the patient.
