Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Adult patient of any gender;
• Patient with clinically significant bilateral age-related cataracts with planned phacoemulsification cataract extraction and suitable for implantation of a posterior chamber trifocal intraocular lens as determined by investigator's medical judgement;
• Projected postoperative corrected distance visual acuity (CDVA) better than 0.2 LogMAR as determined by investigator's medical judgement;
• Preoperative keratometric (corneal) astigmatism ≤1.5 D;
• Clear intraocular media other than cataract;
• Requiring an IOL power within the available range of the investigational IOL (15.0 to +27.0 D, in 0.5 D increments);
• Patient agrees to have surgery of the second eye performed between 1 day and 10 days after the surgery of the first eye.
• Given written informed consent by patient;
• Patient willing and able to comply with examination procedures and schedule for follow-up visits;

You may not qualify if:

• Presence of uncontrolled systemic disease that could increase the operative risk or confound the outcome including but not limited to diabetes mellitus, active cancer treatment, mental illness, dementia, immunocompromised, connective tissue disease, clinically significant atopic disease, etc.;
• Ocular condition that may predispose patient to future complications, per investigator's medical judgement, including but not limited to severe dry eye, anterior segment pathology, glaucoma (uncontrolled despite intake of medication), macular degeneration;
• Clinically significant corneal abnormalities, including corneal dystrophy (epithelial, stromal or endothelial dystrophy), irregularity, inflammation or oedema as per Investigator's medical judgement; conditions including but not limited to keratitis, keratoconjunctivitis, kerato uveitis, keratopathy, keratectasia;
• Previous intraocular or corneal/refractive surgery that might confound the outcome of the investigation or increase the risk to the patient (including corneal transplants, removal of pterygium etc.);
• Use of and foreseeable use of systemic medications that may confound the outcome or increase the risk to the patient per investigator's medical judgement (e.g., steroids, Tamsulosin Hydrochloride or other medications including anticholinergics or alpha-adrenergic blocking agents with similar side effects \[e.g. small pupil/floppy iris syndrome\], anti-metabolites, etc.);
• Patients with diagnosed degenerative visual disorders (e.g. macular degeneration or other retinal disorders, optic nerve atrophy etc.) or any other pathologies of the eye that are predicted to cause future acuity loss to 0.2 LogMAR (CDVA) or worse;
• Patients with conditions that increase the risk of zonular rupture during cataract extraction procedure that may affect the postoperative centration or tilt of the lens;
• Patients with previous refractive surgery procedures, including but not limited to LASIK, limbal relaxing incision;
• Planned concomitant ocular procedure during cataract surgery or within the next 6 months (e.g. glaucoma surgery including implantation of MIGS, astigmatic correction surgery, penetrating keratoplasty, laser-assisted in situ keratomileusis);
• Patients who are expected to require retinal laser treatment within the next 6 months per investigator's medical judgement;
• Amblyopia;
• Rubella, congenital, traumatic or complicated cataracts;
• History of or current anterior or posterior segment inflammation, including but not limited to iritis or uveitis;
• Microphthalmos or macrophthalmos;
• Iris defects (e.g. aniridia);
