Performance, safety and efficiency comparison between 10,000 and 5000 cuts per minute vitrectomy using a 25G cutter:...

Area of Science:

• Ophthalmology
• Surgical Technology
• Medical Devices

Background:

• Vitrectomy surgery is a common ophthalmic procedure.
• The efficiency of vitrectomy probes can impact surgical outcomes.
• Different vitrectomy probe speeds may influence surgical performance.

Purpose of the Study:

• To compare the performance of the 25+® UltraVit® 5000 cuts per minute (cpm) vitrectomy probe against the 25+® UltraVit® 10,000 cpm beveled tip, dual drive vitrectomy probe.
• To evaluate differences in vitrectomy time, posterior vitreous detachment (PVD) induction, intraoperative complications, and instrument usage between two vitrectomy probe speeds.

Main Methods:

• A prospective randomized controlled clinical trial involving 52 eyes of 52 patients.
• Patients were randomized into either a 10,000 cpm (25 patients) or 5000 cpm (27 patients) vitrectomy group.
• Evaluations included preoperative, intraoperative, and postoperative assessments at multiple time points up to 3 months.

Main Results:

• Vitrectomy time was slightly shorter in the 10,000 cpm group (413.7 s) compared to the 5000 cpm group (463.4 s), but this difference was not statistically significant (p=0.5999).
• One iatrogenic retinal break occurred in the 10,000 cpm group, and two occurred in the 5000 cpm group.
• No significant differences were observed in the time for posterior vitreous detachment (PVD) induction or the number of instruments used between the groups.

Conclusions:

• The tested vitrectomy probe speeds (5000 cpm vs. 10,000 cpm) did not yield statistically significant differences in vitrectomy times.
• Surgical efficiency in vitrectomy may be influenced by factors beyond probe speed, such as surgeon technique or other equipment variables.
• Further research may be needed to identify the key determinants of optimal vitrectomy performance.
