Efficacy of Cruise Control in controlling postocclusion surge with Legacy and Millennium venturi phacoemulsification machines

Abstract

In the Legacy machine, the Cruise Control device had a statistically and clinically significant effect. Cruise Control had a large effect on fluidics as well as surge amplitude with the Millennium machine. The greater the flow or greater the initial surge, the greater the impact of the Cruise Control device.

Impact of high and low aspiration parameters on postoperative outcomes of phacoemulsification: Randomized clinical trial

“…Recent developments in phacoemulsification technology have led to benefits including decreased postocclusion surge and improved fluidics. Moreover, user-controlled parameters, such as interrupted phaco modes, vacuum settings, and variable aspiration flow rates, [1][2][3][4][5][6][7][8][9][10][11][12] have increased the safety and predictability of the outcomes of cataract and refractive lens exchange procedures. Furthermore, increased surgeon confidence when using phacoemulsification techniques has led to experimentation with intentionally altered flow parameters.…”

“…Associated benefits of improved technique is protection of the corneal endothelium against damage and less trauma to other intraocular tissues, which can cause complications such as posterior capsule rupture, uveal tissue trauma, and vitreous loss. [1][2][3][4][5][6][7][8][9][10][11][12] In a previous observational study, we explored the intraoperative effect of using low or high fluidic parameters (eg, vacuum settings, bottle heights, and as- . We determined that IOP fluctuations and absolute IOP levels with lower fluidic parameters, specifically aspiration flow rate and bottle height, were lower than with higher fluidic parameters.…”

Laboratory analysis of phacoemulsifier compliance and capacity

“…To a lesser extent, surgeons can control the resistance to outflow by their selection of phacoemulsification needle or their use of an aspiration-line assistive device, such as Cruise Control (Staar Surgical Co.). 2 The smaller the inner diameter of the needle or tubing, the less the surge response but the greater the tendency to clog. Surgeons have no control over system compliance.…”

Comparison of tips in coaxial microincision cataract surgery with the bevel-down technique

“…Several studies 6,7,[9][10][11] have found that the bevel-down technique, which places the bevel opposite the corneal endothelium during phacoemulsification, reduces the effect on the cornea. Despite the many advantages of this technique, it has not been in wide use because intraoperative complications, such as zonular damage or posterior capsule injury, can occur, especially when the surgeon does not have extensive experience with the procedure.…”

“…This technique helps prevent direct corneal endothelial damage by reducing the US energy from the phaco tip. [4][5][6][7][8][9][10][11][12] New machine-based surgical technologies are important to obtain successful cataract surgery outcomes. Since Kelman introduced the phacoemulsification technique, many instruments have been developed, one of which is the Kelman tip.…”
