Interventions
Eligibility Criteria
You may qualify if:
- Patient informed of the consequences and constraints of the protocol and who has given his/her written informed consent
- Patients of any gender, aged 18 years or older
- Assured follow-up examinations
- Post-operative astigmatism ≤ 0.75 Diopter
- IOL implanted into the capsular bag with trifocal IOL in both eyes
- Patients who had bilateral uncomplicated presbyopic lens exchange surgery in both healthy eyes
- Preoperative monocular and binocular CDVA equal or better than 0.2 logMAR
- Normal findings in the medical history and physical examination
You may not qualify if:
- Patients unable to meet the limitations of the protocol or likely of non-cooperation during the trial
- Patients whose freedom is impaired by administrative or legal order
- Concurrent participation in another drug or device investigation that affects patients vision
- Signs of early cataract in either eye
- Preoperative monocular and binocular CDVA worse than 0.2 logMAR
- Clinically significant Posterior capsule opacification (PCO) defined as a CDVA loss of 0.2 logMAR or more in either eye
- Cataract of any grade
- Ocular disorders, that could potentially cause future acuity loss to a level of 0.20 logMAR (best-corrected) or worse in either eye
- Any anterior segment pathology that could significantly affect outcomes (e.g. chronic uveitis, iritis, aniridia, rubeosis iridis, clinically significant anterior membrane dystrophies, poor pupil dilation, etc.)
- Abnormal corneal findings in either eye (e.g. keratoconus, pellucid marginal degeneration, or irregular astigmatism, clinically significant corneal membrane dystrophies)
- Any condition in the study eye that could affect IOL stability (e.g. zonular dialysis, evident zonular weakness or dehiscence, etc.)
- History of any clinically significant retinal pathology or ocular diagnosis (e.g. diabetic retinopathy, ischemic diseases, macular degeneration, retinal detachment, optic neuropathy optic nerv atrophy, amblyopia, strabismus, microphthalmos, aniridia, epiretinal membrane etc.) in the study eyes that could alter or limit final postoperative visual prognosis.
- Patients, who are unable to fixate for a longer time, e.g. strabismus, nystagmus
- Patient expected to require retinal laser treatment before 6 month follow-up visit
- Patient require refractive laser treatment / refractive laser touch-up before 6 month follow up visit
- +8 more criteria
