NCT04861909

Brief Summary

The main aims of this study were to evaluate the patient reported outcomes (PROs), safety and efficacy, after 6-year (66 - 78 months) from the binocular implantation of the AT LISA tri 839MP. A secondary aim was to evaluate new metrics such as contrast sensitivity defocus curves and light distortion analysis.

Outcome Measures

Primary Outcomes (1)

  • Monocular visual acuity

    Visual acuity measured with and without best corrected distance subjective refraction in logMAR scale, lower value meaning better results.

    6 years

Secondary Outcomes (5)

  • Contrast sensitivity defocus curve in logCS

    6 years

  • Light distortion analysis in percentage

    6 years

  • Visual Function Questionnaire (VF-14)

    6 years

  • Patient-Reported Spectacle Independence Questionnaire (PRSIQ)

    6 years

  • Satisfaction, Photic Phenomena and Operated again

    6 years

Study Population

Patients implanted with AT Lisa Tri from March 2014 to June 2015

You may qualify if:

  • Phone call interview:
  • Patients of either sex, 45 years of age or older at the time of surgery and less than 80 years of age at the time of the phone call.
  • Patients implanted bilaterally with the AT LISA 839MP MIOL in the capsular bag.
  • No surgical complications reported in the clinical history that could affect postoperative visual acuity: damage to the capsular bag, intraocular hemorrhage, etc.
  • Operated between 66 months from the first implanted eye and up to 78 months from the surgery of the second eye
  • Patient able to hear, understand and give express consent orally.
  • Study visit:
  • To have participated in the first stage of the study corresponding to the phone call interview.
  • Irregular astigmatism in either eye measured with corneal tomography (total high-order corneal aberrations at 4 mm \< 0.5 μm).
  • Patient able to read, understand and provide a written informed consent form.
  • Sufficient availability, willingness, skills, and cognitive awareness to comply with follow-up/study procedures and study visits.

You may not qualify if:

  • Phone call interview:
  • Any eye disease documented in the patient's clinical history that may potentially cause a loss of visual acuity or diplopia: Active or recurrent pathology of the anterior segment (chronic uveitis, iritis, iridocyclitis, rubeosis iridis, uncontrolled glaucoma, etc.), retinal or optic nerve pathologies such as diabetic retinopathy, macular degeneration, etc.
  • Eye surgery (including laser refractive surgery) performed before or after the operation with the intraocular lens.
  • Study Visit:
  • PCO ≥ 2 according to surgeon criteria that produces a loss of CDVA ≥ 0.2 logMAR
  • Any eye disorder that can potentially cause a loss of visual acuity or diplopia: Active or recurrent pathology of the anterior segment (chronic uveitis, iritis, iridocyclitis, rubeosis iridis, uncontrolled glaucoma, etc.), retinal or optic nerve pathologies such as diabetic retinopathy, macular degeneration, etc.
  • Eye surgery (including laser refractive surgery) performed before or after the operation with the intraocular lens.
  • Use of systemic or ocular medications that may affect vision in the last 6 months.
  • Subjects who participate in any clinical trial or research with drugs or medical devices within 30 days prior to entry into this research and/or during the period of participation in this research.
