NCT07176416

Brief Summary

This study is a single center, prospective study of cumulative dissipated energy and endothelial cells loss per phacoemulsification procedure after successful cataract surgery. Subjects will be assessed 3 months postoperatively at a single visit. Clinical evaluations will include central corneal thickness, specular microscopy, as well as measurement of visual acuities at distance.

Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Eligible test subjects will be adults who are candidates for age-related cataract surgery with IOL implantation.

You may qualify if:

  • Adult patients undergoing age-related cataract surgery.
  • Planned use of the Catalys Precision Laser System.
  • Planned implantation of TECNIS intraocular lenses (IOLs).

You may not qualify if:

  • Moderate-severe any disease state (deemed by the surgeon) that could increase risk of complicated cataract surgery (ie, pseudoexfoliation syndrome, zonular dehiscence, history of eye trauma, and prior refractive surgery).
