NCT05462067

Brief Summary

The purpose of this study is to obtain postoperative visual performance data of patients with bilateral implantation of the AT LARA IOL or the AT LARA implanted in the dominant eye and AT LISA tri implanted in the other eye. Dependence on spectacles, the occurrence of photic phenomena and patient and surgeon satisfaction with the patient's visual performance will be documented. Furthermore, the refraction data will be used to optimize the IOL constants for IOL power calculations.

Outcome Measures

Primary Outcomes (1)

  • Change in preoperative and postoperative binocular Corrected Distance Visual Acuity (CDVA)

    The uncorrected and best corrected distance visual acuity is determined with standard reading charts at a distance of 4 or 5 m; logMar visual acuity is recorded. Near visual acuity (40 cm) and intermediate visual acuity (67 cm) are documented using suitable visual acuity charts for the respective distance or converted using conversion tables. The logMar visual acuity is recorded. Uncorrected visual acuity will be scored for distance, intermediate and near vision: * logMAR 0.0 or better = 5 * logMar 0.1 = 4 * logMar 0.2 = 3 * logMar 0.3 = 2 * logMAR worse than 0.3 = 1 Scores for the individual distances will be added to a total score.

    Pre-op, 2-4 Months, & 5-8 Months

Secondary Outcomes (10)

  • Postoperative uncorrected monocular and binocular distance visual acuity

    2-4 Months, & 5-8 Months

  • Postoperative uncorrected and distance-corrected binocular near visual acuity

    2-4 Months, & 5-8 Months

  • Postoperative uncorrected and distance-corrected binocular intermediate visual acuity

    2-4 Months, & 5-8 Months

  • Reading speed and acuity, and preferred reading distance (Salzburg reading desk)

    2-4 Months, & 5-8 Months

  • Postoperative use of spectacles (near, intermediate, distance)

    2-4 Months, & 5-8 Months

  • +5 more secondary outcomes

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients bilaterally implanted with the AT LARA IOL or the AT LARA and AT LISA tri IOLs or their toric versions
  • Age 18 and older
  • Uncomplicated implantation of study IOLs
  • No visual acuity limiting pathologies
  • Clear intraocular media
  • Availability, willingness and sufficient cognitive awareness to comply with examination procedures
  • Written informed consent for participation in the study and data protection

You may not qualify if:

  • Visual potential of less than 0.63 (decimal) in each eye due to ocular pathologies, e.g. retinal disorders
  • Postoperative CDVA \>0.2 log MAR
  • Visual field loss which has impact on visual acuity
  • Use of systemic or ocular medication that might affect vision
  • Acute or chronic disease, illness, ocular trauma or surgery that would confound results (e.g. macular degeneration, cystoid macular edema, proliferative diabetic retinopathy, etc.)
  • Patients with amblyopia, strabismus, forme fruste keratoconus or keratoconus
  • Capsular or zonular abnormalities that have affected postoperative centration or tilt of the lens (e.g. pseudoexfoliation syndrome)
  • Pupil abnormalities (non-reactive, tonic pupils, abnormally shaped pupils, or pupils that do not dilate at least 3.5 mm under mesopic/scotopic conditions)
