Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Patient informed of the consequences and constraints of the Clinical Investigational Plan and who has given his/her written informed consent
  2. Patients of any gender, aged 18 or older
  3. Assured follow-up examinations
  4. Healthy eyes with clinically significant age related cataract requiring surgical treatment
  5. Corrected distance visual acuity projected to be better than 0.2 logMAR after the cataract surgery, as determined by Investigator's medical judgment

8. Cataract density compatible with biometry measurement

Exclusion Criteria:

  2. Patients whose freedom is impaired by administrative or legal order
  3. Current participation in another drug or device investigation that affects patients vision
  4. Ocular disorders, other than cataract, that could potentially cause future acuity loss
