Purpose
The INTREPID® Hybrid Tip (Alcon) features a rounded polymer edge on the ultrasound tip, that reduces the risk of posterior capsule rupture during cataract surgery. This study examined the impact of this ultrasound tip on the outcomes of cataract surgeries by trainee surgeons.
Setting
This study was conducted in Chukyo Hospital, Nagoya, Japan, organized by Japan Community Health care Organization.
Methods
In a preliminary study, we retrospectively selected 70 patients(95 eyes) who underwent cataract surgery performed by four experienced surgeons were selected retrospectively. Initial findings suggested that using hybrid tip with the same settings as a balanced tip might reduce surgical efficiency. The settings were adjusted to evaluate both surgical efficiency and safety. We enrolled 84 patients (96 eyes) undergoing cataract surgery performed by three trainee surgeons. The two tips were alternately used, with the torsional power of the hybrid tip set 10% higher than that of the balanced tip. Various parameters, including cumulative dissipated energy (CDE) and postoperative clinical outcomes, were compared between the two groups.
Results
We examined 42 eyes in the Hybrid Tip group and 54 eyes in the Balanced Tip group that met the criteria. The mean CDE values in the Hybrid Tip group(14.6±8.2) were significantly higher than those in the Balanced Tip group(9.8±5.8)(p=0.008). However, the mean total ultrasound time, the time for ultrasound tip insertion in the anterior chamber, corrected visual acuity, intraocular pressure, and corneal endothelial cell density were not significantly different between groups. Neither intraoperative nor postoperative complications, such as posterior capsule rupture, were reported.
Conclusions
The INTREPID® Hybrid Tip slightly decreased surgical efficiency, but could be comparable with the balanced tip by adjusting the ultrasound settings, without impacting postoperative outcomes and complications in cataract surgeries performed by trainee surgeons.
