Comparison of postoperative comfort in 20 gauge versus 23 gauge pars plana vitrectomy.
OBJECTIVE
Although the sutureless 23Gauge (23G) vitrectomy technique is being increasingly used, a significant number of pars plana vitrectomies are still conducted using the 20G technique. This study evaluates whether the 23G vitrectomy causes less postoperative pain, less discomfort and a shorter duration of sick leave than the 20G vitrectomy.


METHODS
In 2006, a questionnaire was sent to 877 patients who had undergone either 20G or 23G pars plana vitrectomy for different indications. Postoperative pain, discomfort of the eye and duration of sick leave were evaluated. Data for analysis was obtained from 544 patients.


RESULTS
After receiving a 20G pars plana vitrectomy, patients had a significantly increased risk of sleeping less during the first postoperative night and week, waking up because of pain during the first postoperative night and week, taking pain medication during the first postoperative night and week and using a postoperative ointment. The 20G group also experienced a longer period of postoperative discomfort and reddish eyes.


CONCLUSIONS
23G pars plana vitrectomy causes significantly less postoperative pain and discomfort compared to 20G pars plana vitrectomy. The similar duration of leave in the patient groups could be explained because a fibrin sealant was used in the 20G group.
