TLDR
The new torsional software significantly decreased occlusion time and balanced salt solution use over standard torsion software, particularly with denser cataracts, and the net result was a relatively better safety cataract surgery profile.Abstract:
Purpose To evaluate the efficiency profile of new torsional phacoemulsification software. Setting Eye Institute of Utah, Salt Lake City, Utah, USA. Design Comparative case series. Methods Routine cataract surgeries were performed using standard torsional (Ozil) and new torsional (Ozil IP) software. The new software uses occasional pulses of longitudinal energy that are operator specified and system controlled to manage potential occlusion. The new software was compared with the previous standard software, which did not include this option. The video monitor system was recorded in high definition. Measurement of cumulative dissipated energy, balanced salt solution use, and amount of time spent in occlusion were measured in a frame-by-frame review of the recorded videos. Data were categorized for analysis by software group and cataract grade (1 to 4). Results The study comprised 59 eyes that had cataract removal using the new torsional software and 59 eyes using the standard torsional software. Cumulative dissipated energy was not statistically significantly different between the 2 groups. Balanced salt solution use, time spent in occlusion, and the mean longest continuous occlusion were significantly lower with the new torsional software; these differences were greater as the cataract grade increased. Conclusions The new torsional software significantly decreased occlusion time and balanced salt solution use over standard torsional software, particularly with denser cataracts. The net result was a relatively better safety cataract surgery profile. Financial Disclosure No author has a financial or proprietary interest in any material or method mentioned.read more

Endothelial cell loss: Biaxial small-incision torsional phacoemulsification versus biaxial small-incision longitudinal phacoemulsification
TL;DR: The risk for high endothelial cell loss should be considered when the phacoemulsification of high‐density nuclear cataracts is performed using either method.

Comparison of 45-degree Kelman and 45-degree balanced phaco tip designs in torsional microcoaxial phacoemulsification
TL;DR: Torsional phacoemulsification performed with a balanced tip provided more effective lens removal with less total US time, torsional time, CDE, and BSS use, as well as similar changes in ECD with a Kelman tip in all cataract grades.

TL;DR: Torsional phacoemulsification was more effective than longitudinal phacoEmulsification in the amount of applied fluid and the quantity of US energy expended and with the torsional method, it was possible to maintain a constant ratio of amount of fluid flow to quantity ofUS energy used, regardless of nucleus density.

TL;DR: Lower operating temperatures indicate lower heat generation within the same volume of fluid, and this may provide additional thermal protection during cataract surgery.

Comparison of endothelial changes and power settings between torsional and longitudinal phacoemulsification
TL;DR: The torsional mode was as safe as the longitudinal mode in phacoemulsification for age‐related cataract as well as conventional longitudinal mode, according to Conference on Harmonisation‐E9 Guidelines.

Cumulative tip travel and implied followability of longitudinal and torsional phacoemulsification
TL;DR: Torsional phacoemulsification using an angled tip required less surgeon‐generated tip travel and less time, suggesting that nuclear material may be more efficiently approximated to and aspirated through the tip aperture throughout the phacoemsulsification process.
