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.

Eligibility Criteria
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.
