Layout table for eligibility information
Ages Eligible for Study:   50 Years to 80 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patient informed of the consequences and constraints of the Clinical Investigational Plan and who has given his/her written informed consent;
  • Patients of any gender, aged 50 to 80 years;
  • Assured follow-up examinations;
  • clinically significant bilateral cataract;

Exclusion Criteria:

  • Patients unable to meet the limitations of the Clinical Investigational Plan or likely of non-cooperation during the trial;
  • Patients whose freedom is impaired by administrative or legal order;
  • Current participation in another drug or device investigation;
  • Ocular disorders, other than cataract, that could potentially cause future acuity loss to a level of 0.20 logMAR (corrected) or worse in either eye
  • Any anterior segment pathology that could significantly affect outcomes (e.g. chronic uveitis, iritis, corneal dystrophy, etc.)
  • Pseudoexfoliations syndrome
  • Pathologic miosis or Pharmacotherapy with miotic agent
  • Keratoconus
  • Chronic or recurrent uveitis
  • Diabetic retinopathy
  • Uncontrolled glaucoma and or IOP>24mmHg
  • Choroidal hemorrhage,
  • All kind of infections (acute ocular disease, external/internal infection, systemic infection)
  • Traumatic cataract
  • Aniridia
  • Microphthalmia
  • Amblyopia
  • Degenerative visual disorders (e.g. macular degeneration, optic nerve atrophy, or retinal disorders)
  • Patient expected to require retinal laser treatment before the end of the 4-6 months follow-up
  • Previous intraocular and corneal surgery
  • Expected postop. astigmatism greater than 1 D
  • Any type of corneal disorder
  • Systemic or ocular pharmacotherapy, which can impact the visual acuity,
  • Former, current or foreseeable application of Tamsulosin or Silodosin (e.g. Flomax, Flomaxtra, Rapflo) ) which potentially can cause the floppy iris syndrome, insufficient dilation, or missing of appropriate iris structures which can compromise the standard procedure according to the investigator's opinion
  • Patients who are unable to fixate for longer time (e.g. strabismus, nystagmus)
  • Dementia
  • pregnancy or lactation period for female patients
