Objective:
To determine whether surgical warm-up affects epiretinal membrane (ERM) peeling complication rates and surgical case times.
Setting:
Jewish General Hospital, Montreal, QC, Canada.
Design:
Retrospective case-control study.
Methods:
We assessed consecutive patients who underwent pars plana vitrectomy for ERM peel (macular pucker) by one surgeon at the Jewish General Hospital from January 2006 until March 2016. Cases evaluated were sequential ERM peels performed as the first 2 surgeries of the day. The first case of the day was considered the "warm-up" and the second case was the "post-warm-up." Baseline demographics, pre-operative characteristics, perioperative and postoperative best-corrected visual acuity (BCVA) at 2 months and 6 months, as well as postoperative complications are described. Results were analyzed using the χ2 test, t test, and Fischer's exact test. Regression models were used to identify any predictors of postoperative BCVA.
Results:
The study reviewed 108 patients. The warm-up group was compared with the post-warm-up group, and there was no significant difference between the mean pre-operative BCVA and the post-operative BCVA at 2 and 6 months. ERM peeling surgery complication rates were not statistically different between the warm-up cases and the post-warm-up cases. There was a tendency for performing complex surgeries that needed phaco procedures in post-warm-up cases (13% vs 2%, p = 0.03). Analysis of simple ERM peeling procedures (with no concomitant phaco procedures) showed no statistically significant tendencies for any of the groups to go beyond the 60 minutes allocated for the surgery (25.4% vs 20.0%, p = 0.27).
Conclusion:
Warming-up does not influence the rate of postoperative complications or the postoperative BCVA in patients undergoing ERM peels. The strongest predictor of post-operative BCVA was pre-operative BCVA.
Insights
Surgical warm-up before epiretinal membrane (ERM) peeling does not impact complication rates or visual outcomes. Pre-operative vision remains the strongest predictor of post-operative results in ERM surgery.
Area of Science:
- Ophthalmology
- Surgical Outcomes
- Retinal Surgery
Background:
- Epiretinal membrane (ERM) peeling is a common surgical procedure.
- The potential impact of a "surgical warm-up" on operative outcomes is not well-established.
- Optimizing surgical performance and patient safety is a priority in retinal surgery.
Purpose of the Study:
- To investigate whether a surgical warm-up period influences complication rates and surgical case times for epiretinal membrane (ERM) peeling.
- To assess the effect of the first surgery of the day (warm-up) versus the second surgery (post-warm-up) on patient outcomes.
Main Methods:
- A retrospective case-control study involving 108 patients undergoing ERM peeling by a single surgeon.
- Comparison of complication rates, best-corrected visual acuity (BCVA) at 2 and 6 months, and surgical times between "warm-up" (first case) and "post-warm-up" (second case) surgeries.
- Statistical analysis included chi-squared, t-tests, Fischer's exact test, and regression models.
Main Results:
- No significant differences in postoperative BCVA at 2 and 6 months between warm-up and post-warm-up groups.
- ERM peeling complication rates were similar between the two groups.
- A trend towards more complex surgeries (requiring phacoemulsification) in the post-warm-up group was observed (13% vs 2%, p=0.03).
Conclusions:
- Surgical warm-up does not appear to affect postoperative complication rates or visual acuity after ERM peeling.
- Pre-operative visual acuity is the most significant predictor of postoperative BCVA.
- The findings suggest that the order of cases in a surgical day does not critically impact ERM peeling outcomes.
