Outcome Measures

Primary Outcomes (2)

  • Primary Safety Endpoint: Rates of Adverse Events

    The objective is to compare the SPE (Safety and Performance Endpoints) rates of the investigational product to reference data stated in the according ISO standard for posterior intraocular lenses (EN ISO 11979-7:2018) based on minimum 100 subjects.

    120-180 days postoperative

  • Primary Performance Endpoint: Best Corrected Distance Visual Acuity

    The primary performance endpoint is to show non inferiority of Isatis TF compared to the monofocal comparator in terms of best corrected distance visual acuity (CDVA) by means of statistical significance.

    120-180 days postoperative

Secondary Outcomes (3)

  • Secondary Safety Endpoint: Best Corrected Distance Visual Acuity compared to historical data

    120-180 days postoperative

  • Secondary Performance Endpoint: Distance Corrected Near Visual Acuity (DCNVA)

    120-180 days postoperative

  • Secondary Performance Endpoint: Distance Corrected Intermediate Visual Acuity (DCIVA)

    120-180 days postoperative

Other Outcomes (47)

  • Monocular Uncorrected Distance Visual Acuity (UDVA) under photopic light conditions

    Preoperative, 1-2 days postoperative; 7-14 days postoperative, 30-60 days postoperative, 120-180 days postoperative

  • Binocular Uncorrected Distance Visual Acuity (UDVA) under photopic light conditions

    120-180 days postoperative, 330-420 days postoperative

  • Monocular Corrected Distance Visual Acuity (CDVA) under photopic light conditions

    Preoperative, 7-14 days postoperative, 30-60 days postoperative, 120-180 days postoperative, 330-420 days postoperative

  • +44 more other outcomes

Eligibility Criteria

Age50 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Clinically documented age-related cataract in both eyes with no comorbidity;
  • Calculated IOL power is within the range of the investigational IOLs;
  • Male or female adults ages 50 years or older on the day of screening who have cataracts in both eyes;
  • Regular corneal astigmatism (measured by topographer)
  • Astigmatism ≤1.0 D (measured by an automatic keratometer)
  • Clear intraocular media other than cataract;
  • Availability, willingness and sufficient cognitive awareness to comply with examination procedures;
  • Signed informed consent.

You may not qualify if:

  • Age of patient \< 50 years;
  • Regular corneal astigmatism \>1.0 dioptres (measured by an automatic keratometer)
  • Irregular astigmatism (measured by topographer);
  • Difficulty for cooperation (distance from their home, general health conditions);
  • Subjects with diagnosed degenerative visual disorders (e.g. macular degeneration or other retinal or optic disorders);
  • Subjects with AMD suspicious eyes as determined by OCT examination;
  • Previous intraocular or corneal surgery;
  • Traumatic cataract;
  • Instability of keratometry or biometry measurements; Acceptable maximum standard deviation: AL: ± 150 µm; ACD: ± 150 µm; K1 / K2: ± 0.15 D;
  • Ocular hypertension, suspicious glaucoma or glaucoma;
  • Pupil abnormalities (non-reactive, tonic pupils, abnormally shaped pupils or pupils that do not dilate under mesopic / scotopic conditions);
  • Expected complicated surgery;
  • Ocular surface disease (clinical symptoms or keratitis);
  • Pregnancy or lactation;
  • Second eye treatment will only be performed when Best Corrected Distance Visual Acuity (CDVA) of first eye is ≤ 0.2 logMAR (≥ 0.63 decimal);
  • +5 more criteria
