Phaco ultrasound time and corneal endothelial cell loss using Veritas
Assessment of Effective Phaco Time and Endothelial Cell Loss When Using a Novel Dual Mode Phacoemulsification System
This project will test whether using the Veritas vision system changes the amount of ultrasound energy used and corneal endothelial cell loss in adults having age-related cataract surgery with the Catalys laser and TECNIS intraocular lenses.

What this trial studies
This is a single-center, prospective observational study measuring cumulative dissipated energy during phacoemulsification and subsequent endothelial cell loss after uncomplicated cataract surgery using the Veritas Vision System. Participants are adults undergoing age-related cataract surgery with planned use of the Catalys Precision Laser System and implantation of TECNIS IOLs. Surgical phaco energy data will be recorded intraoperatively, and patients will return for a single postoperative assessment about three months after surgery. At the postoperative visit investigators will measure endothelial cell counts by specular microscopy, central corneal thickness, and distance visual acuity to quantify any cell loss and functional changes.
Who should consider this trial
Good fit: Adults having age-related cataract surgery who will be treated with the Catalys laser and receive TECNIS intraocular lenses, and who do not have eye conditions that increase the risk of complicated surgery.
Not a fit: Patients with conditions that increase surgical complexity (for example pseudoexfoliation, zonular dehiscence, prior ocular trauma, prior refractive surgery) or those with non–age-related cataracts may not benefit from the findings.
Why it matters
Potential benefit: If successful, this could show that using the Veritas system reduces phaco energy and preserves corneal endothelial cells, leading to fewer corneal complications and better visual recovery.
How similar studies have performed: Previous research has shown that reducing cumulative phaco energy can lower endothelial cell loss after cataract surgery, but published data specific to the Veritas system are limited.
