CRST: The Podcast

UNITYtime Podcast is back. Join Drs. Lori Provencher* and Arjun Hura* as they take
an unscripted look at the science behind UNITY® 4D Phaco and volumetric ultrasound. Drawing on
independent research and real surgical cases, they explore how improved efficiency, followability,
and fluidics may help surgeons approach both routine and complex cataract procedures with greater
confidence.

4:25 - Compared to CENTURION and CONSTELLATION Vision Systems. Based on bench data.
8:09 - Based on bench data.
Trademarks are the property of their respective owners.
Based on N=10 HPs, Artificial cataract lens IOP 55mmhg vacuum of 450 mmHg
9:50 - For posterior segment surgeries/posterior cassette pack; approximately 1.7 minutes faster.
For posterior segment surgeries/posterior cassette pack; approximately 1.4 minutes faster.
For posterior segment surgeries/posterior cassette pack; approximately 0.35 minutes (21 seconds)
faster.
10:00 – Based on bench data.
66 cadaver porcine eyes (33 Tors, 33 4D) and 64 artificial lenses (32 Tors, 32 4D); p<0.001.
13:41 - 66 cadaver porcine eyes (33 Tors, 33 4D) and 64 artificial lenses (32 Tors, 32 4D); p<0.001.
15:18 - Based on an adjusted multivariable regression analysis which resulted in a mean difference
of -1.71 percent-seconds for CDE with the UNITY VCS/CS ® (n=139) console compared to
CENTURION™ Vision System with AS (n=160). Most patients in the real-world study had non-dense
cataracts (≤2+ nuclear density measurement; 64.8% for UNITY VCS/CS® and 72.0% for
CENTURION™ Vision System with AS) and received FLACS (FLACS only, FLACS + there devices;
35.9%, 24.6% for UNITY VCS/CS® and 34.2%, 23.6%for CENTURION™ Vision System with AS).
Performance may also be impacted by the surgeon's machine settings.
35:07 - Based on bench data. Reduction in surge is correlated to less change in anterior chamber
depth.
36:58 - 66 cadaver porcine eyes (33 Tors, 33 4D) and 64 artificial lenses (32 Tors, 32 4D); p<0.001.
51:30 - Mean fluctuation at flow vs. setpoint of 2.36 ± 2.13, 4.19 ± 1.97, 1.84 ± 2.82, and 2.13 ± 2.86
mmHg during phacoemulsification, irrigation/aspiration (IA), vitrectomy, and extrusion/fragmentation,
respectively.
52:58 - Clinical evidence of physiologic IOP was established using CENTURION with Active Sentry;
UNITY VCS/CS utilizes advanced Intelligent IOP designed with the same physiologic principles.
55:29 - Based on bench data.
Trademarks are the property of their respective owners.
Based on N=10 HPs, Artificial cataract lens IOP 55mmhg vacuum of 450 mmHg
56:11 - Based on bench data.

How should eye care providers approach patients with concurrent glaucoma and catracts? And when does cataract surgery alone fall short? In this episode of CRST: The Podcast, Anupam Laul, OD, FAAO, and Sahar Bedrood, MD, PhD, work through 3 real-world cases covering ocular hypertension with visually significant cataracts, primary open-angle glaucoma with rapid RNFL progression, and acute angle closure with a large crystalline lens. The discussion covers SLT timing, MIGS selection, sustained-release drug delivery, IOL choice in glaucoma patients, and when trabeculectomy remains the right call.

In this episode of Best Practices in Keratoconus Management, Bradon D. Ayres, MD is joined Parag Majmudar, MD, and Neel S. Vaidya, MD, MPH, to discuss their early experiences with Epioxa now that it is available for the treatment of progressive keratoconus. Discover how they are incorporating Epioxa into their practices, their initial treatment successes, and what they have learned from their initial wave of patients. They also explore how this new treatment option may influence their approach to crosslinking and help them take a more proactive approach to keratoconus management.

Neda Nikpoor, MD, and Neda Shamie, MD, are joined by Radhika Rampat, MBBS, BSc(Hons), FRCOphth, for an exploration of sustainability in ophthalmology. They discuss the AECOS Green Working Group, waste reduction, and how to champion sustainability locally.

What does it take to make every surgical consultation feel individualized amid increasing pressure for efficiency? George O. Waring IV, MD, speaks with Alexandra Dean, Director of Practice Development at Waring Vision Institute, about building a counseling continuum that starts before the patient arrives and uses intake forms, previsit outreach, and cohesive handoffs to connect clinical recommendations with individual goals. Dean also shares practical guidance on training nonclinical counselors, using technology without losing the human touch, and creating an experience patients remember for how it made them feel.
