Evaluating outcomes of Clareon Vivity lenses in patients with previous vision correction surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to assess the clinical outcomes of patients who have undergone bilateral cataract surgery using Clareon Vivity intraocular lenses (IOLs) after having previous myopic refractive surgery, such as LASIK or PRK. The study focuses on patients with age-related cataracts who are otherwise healthy and have a history of uncomplicated refractive surgery. By analyzing visual acuity and other outcomes post-surgery, the study seeks to provide insights into the effectiveness of these lenses in achieving good vision at various distances. The research is based on data from an international registry and aims to address the challenges faced by post-refractive surgery patients in achieving predictable visual outcomes.

Why it matters

Who can join: the full rules

Inclusion Criteria:

* o Bilateral age-related visually significant cataracts in otherwise healthy eyes, undergoing uncomplicated bilateral sequential Clareon Vivity IOLs

  * Prior history of uncomplicated post-refractive myopic surgery (LASIK/PRK) with up to 1 enhancement treatment
  * Potential acuity measured post-operatively 20/25 or better in both eyes
  * Patients with regular astigmatism that can be managed with T3 toric lens or arcuate incision

Exclusion Criteria:

* o Ocular or systemic comorbidities that may alter or reduce visual acuity and contrast sensitivity such as severe dry eye/ocular surface disease, glaucoma, macular degeneration, retinopathy, neuro-ophthalmic diseases, etc.

  * Prior ocular surgeries other than uncomplicated corneal refractive surgery and excluding RK
  * Patients with irregular astigmatism/topography (to rule out signs of potential ectasia), corneal dystrophies, and pupil abnormalities
  * Total HOA cutoff of ≤0.5, coma ≤0.3
  * RLE patients
