Recent research progress in the subjective visual perception during cataract surgery

Subjective visual perceptions experienced by patients during cataract surgery under local anesthesia have been given more and more attention now. Intraoperative visual experiences, including non-light perception, light perception, one or more color sensation, flash, movement, instrument, hands or fingers of surgeon etc. ,are complained in parts of patients. These sensations and experience often lead to a fear of patient. Being aware of these intraoperative sensations of fear from patient is necessary for us to take the preventing strategy in advance. In addition,counseling of these patients prior to surgery may alleviate fears and improve the satisfaction of patient with surgery outcome. This paper reviewed the current studies on this phenomenon, discussed its clinical implications and possible mechanism, and suggested novel approaches to reduce its negative impact on the surgery.
