Eligibility Criteria
You may qualify if:
- age-related bilateral cataract
- Age 21 or older
- Visual acuity \> 0.05
- Axial length: 21.00-27.00mm
- Astigmatism \< 1.0 dpt
- Normal findings in the medical history and physical examination
- Written informed consent prior to surgery
You may not qualify if:
- Reduced contrast vision, binocularity or stereoscopic vision (e.g. amblyopia, strabismus)
- Active ocular disease (e.g chronic uveitis, diabetic retinopathy, chronic glaucoma not responsive to medication, corneal dystrophies, etc.) precluding good post- operative visual acuity
- Relevant other ophthalmic diseases such as pseudoexfoliation syndrome
- Irregular astigmatism on corneal tomography
- Pronounced dry eye disease
- Nystagmus or pathologies that might affect patient's fixation
- Previous ocular surgery or trauma
- Persons who are pregnant or nursing
