CATARACT surgery under local anesthesia is a widely accepted technique among ophthalmologists. A significant problem, however, is that of providing adequate circulation of air or oxygen underneath the drapes. We have attempted to resolve this by designing a frame which would hold the drapes away from the patient, and at the same time, deliver him a supply of air or oxygen.
After much deliberation and examination of various possible designs, the present prototype frame was constructed (Fig 1 and 2).
The frame was made to adjust to various positions and yet to support the weight of the surgeon's arm when necessary.
Patients undergoing cataract surgery under regional anesthesia are usually sedated. It is important, therefore, for safety's sake and for comfort that no fixed objects be placed above the patient's face, in case he should suddenly raise his head. It is for this reason that we have constructed the frame
