A Comparative Study of 23-Gauge and 27-Gauge Vitrectomy for Puckers or Floaters, Including Evaluation of the Effect of Combined Phaco-Vitrectomy Surgery on Postoperative Outcome.

ABSTRACT:

Introduction

A single-center, prospective randomized comparison of postoperative recovery between 23-gauge and 27-gauge surgical approaches in vitrectomy was performed.

Methods

A single-center, prospective randomized comparison of postoperative recovery between 23-gauge and 27-gauge surgical approaches to evaluate efficiencies and postoperative outcomes of the two surgical gauges. Eighty patients who were scheduled to undergo pars plana vitrectomy (PPV) for floaters or macular surgery were treated with either 27-gauge or 23-gauge techniques and assessed for efficiency of the procedures as well as a variety of postop indicators of pain and inflammation.

Results

27-Gauge vitrectomy took 90 s more time compared to 23-gauge surgery. Wound closure was significantly easier in 27-gauge than 23-gauge. Less postoperative eye reddishness was seen in 27-gauge compared to 23-gauge. A trend towards less inflammation was seen in 27-gauge.

Conclusion

Overall, the trial showed that 27-gauge has the better postoperative outcome compared to 23-gauge PPV. Combining vitrectomy with phaco-surgery did not influence the study outcome parameters.

Project description:IntroductionTo compare the transconjunctival sutureless 23 gauge (G) pars plana vitrectomy (PPV) with 20 G PPV regarding inflammation, safety, visual outcome and patient comfort.MethodsWe included 103 patients with symptomatic macular hole or macular pucker, scheduled for vitrectomy in this prospective, randomized, controlled, mono-center clinical trial. Patients were randomized 1:1 to either 20G PPV (n = 51) or 23G PPV (n = 52). All eyes underwent standard 20G or 23G PPV with membrane peeling. Primary outcome measure was change in aqueous humor flare 3 weeks after surgery compared with baseline. Secondary outcome measures were flare values 2 days and 26 weeks after surgery, subjective discomforts measured with a visual analog scale, best-corrected visual acuity, duration of surgery, intraocular pressure (IOP) and adverse events.ResultsThere was no significant difference in change of flare 3 weeks after PPV [- 1.7, 95% CI (- 6.3 to 2.9), p = 0.466]. Both groups showed a significant increase in flare 2 days after surgery (20G: p < 0.001, 23G: p = 0.002), but only the 20G group after 3 weeks (p = 0.011). The gain in visual acuity after 3 weeks was higher after 23G PPV (4.2 95% CI (0.4-8.0, p = 0.029), but without a difference after 6 months. The duration of surgery was shorter in the 23G group (p < 0.001). Patient comfort 3 weeks after surgery was greater after 23G PPV (foreign body sensation p = 0.002; itching: p = 0.021). However, the rate of complications did not differ between the groups.ConclusionThe primary aim, showing the superiority of the 23G group regarding the change of flare value from baseline to 3 weeks after surgery, was not met, but the level of inflammation decreased faster after 23G PPV. Clear advantages of the 23G PPV were a lower risk of postoperative IOP elevation, a shorter surgery time, faster visual recovery and greater patient comfort in the early postoperative phase.Clinical trial registration numberClinicalTrials.gov NCT01969929.
