Prospective Multicenter Clinical Study on the Visual and Refractive Outcomes and Safety Outcomes Following Implantation of an AddOn Intraocular Lens in Previously Pseudophakic Eyes

1. The subject must read and sign the Informed Consent form.
2. The subject must appear able and willing to adhere to the instructions set forth in this clinical protocol.
3. Adult males or females above 18 years of age.
4. No other ocular co -morbidity (i.e. no history of ocular surface disease, severe dry eye, glaucoma, retinal or macular pathology)
5. Pseudophakia.
6. Uncomplicated cataract surgery or clear lens extraction followed by an uneventful recovery period of at least 3-months.
7. Stable primary IOL located in the capsular bag.
8. Anterior chamber depth (ACD) of at least 2.8 mm (measured from corneal endothelium to the anterior surface of the primary IOL in the capsular bag with an optical biometer [Lenstar, IOL Master]).
9. Subjects with residual refractive error that is suitable for correction with a secondary add-on IOL.
10. Subjects, who have stable post-operative refraction at month two following uncomplicated primary lens surgery.
11. Subjects with myopia of not more than 6.0 diopters.
12. Subjects with monocular corrected distance visual acuity (CDVA) of Snellen 6/7.5 (20/25; LogMAR=0.1, decimal=0.80) or better.
13. Subjects with a preoperative pharmacologically dilated pupil diameter of 6.5 mm or more.

Exclusion Criteria:

1. Currently pregnant or lactating.
2. Prisoners or young offenders in custody
3. Adults lacking capacity to consent for themselves
4. Phakic or aphakic status.
5. Narrow angle, i.e. \< Schaefer grade 2
6. Pseudophakic patients with malpositioned, subluxated or unstable capsular fixated intraocular lens.
7. Patients with a multifocal capsular bag fixated IOL.
8. Inability to achieve secure placement in the designated location e.g. due to absence of a secure peripheral anterior capsule, absence of intact zonules, or irregular anatomy of the ciliary sulcus.
9. Active ocular diseases (chronic severe uveitis, proliferative diabetic retinopathy, chronic glaucoma not responsive to medication, iris atrophy, severe zonulopathy, pigment dispersion syndrome).
10. Corneal abnormalities such as Unstable Keratoconus, irregular astigmatism.
11. Existing ocular conditions such as age-related macular degeneration (AMD) and other progressive retinal degenerations.
12. Any previous ocular co-morbidity including pseudoexfoliation, zonular weakness, pseudophakodonesis, complicated cataract surgery, narrow angle glaucoma or macular pathology, congenital eye abnormality, microphthalmia.
13. Any eye disease in which postoperative visual acuity is not expected to be better than 0.5 decimal (e.g. amblyopia, nystagmus, retinitis pigmentosa, aniridia, eccentric pupil)
14. Subjects with pathological pupil reactions.
15. Subjects with untreated posterior capsule opacification (PCO), which results in at least 1-line decrease in visual acuity and/or in loss of contrast sensitivity (CS).
16. Any systemic disease (e.g., Sjögren's syndrome), allergies, infectious disease (e.g., hepatitis, tuberculosis), contagious immunosuppressive diseases (e.g., HIV), autoimmune disease (e.g. rheumatoid arthritis), or other diseases, by self-report, which are known to interfere with visual function and/or participation in the study.
17. Use of systemic medications (e.g., chronic steroid use) that are known to interfere with visual function.
18. Any ocular allergies, infections or other ocular abnormalities that are known to interfere with visual function and/or participation in the study.
19. Any previous, or planned (during the course of the study) ocular surgery (e.g., radial keratotomy, PRK, LASIK, etc.)
20. Any greater than Grade 2 slit lamp findings (e.g., oedema, corneal neovascularisation, corneal staining, tarsal abnormalities, conjunctival injection, corneal decompensation) or any other ocular abnormality that may contraindicate the implantation of the supplementary IOL.
21. Any history or signs of a corneal inflammatory event, or any other ocular abnormality
22. Participation in any intraocular lens, contact lens or lens care product clinical trial within 30 days prior to study enrollment.
23. Employee, relative or friends of employees of any ophthalmic company, or investigational clinic (e.g., Investigator, Coordinator, Technician)
