In a prospective survey, 121 patients received sub-Tenon's block and were interviewed on the same day after their phacoemulsification cataract surgery regarding their visual experience in the operated eye during surgery. Majority of patients (81) reported that they could see some light during surgery and various colours were seen by 56 Movements of various descriptions were also reported by 404570360f patients. The majority of patients (93) found the visual experience acceptable but 4thought it to be unpleasant and 3 0.000000ound it frightening. Patients undergoing phacoemulsification surgery under sub-Tenon's block experience a variety of visual sensations and some patients may be frightened. All patients should receive appropriate preoperative warning.
