title: Prospective study of cooperation and satisfaction in glaucoma surgery under sub-Tenon's anesthesia.
abstract: OBJECTIVE
  To evaluate the analgesic effect as well as patient cooperation and satisfaction with sub-tenon's anesthesia in glaucoma surgery.
  
  
  METHODS
  Prospective uncontrolled study. Fifty-three patients who underwent glaucoma surgery, with or without cataract extraction, with sub-Tenon's anesthesia have been studied. Satisfaction and cooperation were evaluated on a qualitative scale. The pain level was quantified using a numerical scale from 1 (no pain) to 10 (unsupportable pain).
  
  
  RESULTS
  The mean pain score at the different periods was: 2.13 (standard deviation [SD] 1.47) on administering anesthesia, 1.74 (SD 1.27) during the surgery, 1.63 SD (1.23) immediately after the procedure, 1.38 (SD 0.38) 30 min later, and 1.38 (SD 0.63) when leaving the recovery unit. The postoperative satisfaction was "fairly or very satisfied" in 92.6% of the cases for both the surgeons and the patients. Twenty-four patients complained during the surgery, 15 of them at the conjunctival suture; in these cases additional anesthesia was administered, and, in 4 cases, intravenous paracetamol was given. Pain scores were significatively higher during the surgery (P=.033), and immediately after the procedure (P=.027) in trabeculectomy than in deep sclerectomy patients.
  
  
  CONCLUSIONS
  The good analgesic level reached led to a high level of patient and surgeon satisfaction, even in longer procedures such as deep sclerectomy combined with cataract extraction, or implantation of drainage devices. Pain scores were significatively higher in trabeculectomy than in deep sclerectomy patients.
