Effects of peribulbar block and incisionless sub-Tenon’s block on sleep quality after cataract surgery

The incisionless sub-Tenon's block was superior to the peribulbar block in terms of providing akinesia and reducing the need for maintenance anesthetic medications such as sedatives or analgesics. Although chemosis and subconjunctival hemorrhage occurred more frequently in the incisionless sub-Tenon's group, all events were transient and had no serious clinical significance. The 2 regional techniques were similar in terms of postoperative sleep quality and patient satisfaction.
