Overview

This study is a multicentric, prospective, randomised, controlled, post-market clinical follow up (PMCF) study to investigate safety, visual outcomes and contrast sensitivity after bilateral implantation of either LuxSmart IOLs (study group) or LuxGood IOLs (control group).

Eligibility

Inclusion Criteria:

1. Clinically documented age-related cataracts in both eyes;
2. Calculated IOL power performed using an optical biometer is within the range of the study and control IOLs (15D to 28D);
3. Male or female adults aged 22 years or older on the day of first-eye surgery;
4. Regular corneal astigmatism ≤ 1.0 D (measured by IOL Master) in both eyes;
5. Clear intraocular media other than cataract in both eyes;
6. Willing and able to comply to the study requirements;
7. Capability to understand and sign an IRB approved informed consent form and privacy authorization;
8. Monocular best corrected visual acuity projected to be ≤ 0.18 logMAR (≥ 20/30 in Snellen) after IOL implantation in both eyes;
9. Subjects must have discontinued use of contact lenses for at least two weeks (for hard or toric lenses) or 3 days (for soft non-toric contact lenses) prior to the pre-operative examination, and throughout the clinical study;
10. Current contact lens wearers must demonstrate a stable refraction (within ±0.5 D for both sphere and cylinder) in each eye, as determined by distance manifest refraction on two consecutive examination dates after discontinuation of contact lens wear;

Exclusion Criteria:

1. Regular corneal astigmatism >1.0 D (measured by IOL Master) in one or both eyes;
2. Irregular astigmatism (measured by a topographer) in both eyes;
3. Difficulties for cooperation;
4. Subjects with diagnosed degenerative visual disorders (e.g. macular degeneration or other retinal or optic disorders) that are predicted to cause future acuity loss to 20/30 or worse in one or both eyes;
5. Subjects with AMD suspicious eyes as determined by OCT examination;
6. Previous intraocular or corneal surgery in one or both eyes;
7. Traumatic cataract in one or both eyes as judged by investigator;
8. History or presence of macular edema in one or both eyes;
9. Instability of keratometry or biometry measurements; Acceptable maximum standard deviation: AL: ± 150 µm; ACD: ± 150 µm; K1 / K2: ± 0.15 D in both eyes;
10. Clinically significant, uncontrolled glaucoma with expected negative impact on Contrast Sensitivity and / or visual acuity outcomes in one or both eyes;
11. Pupil abnormalities (non-reactive, tonic, abnormally shaped) in one or both eyes;
12. Subjects that cannot achieve a minimum pharmacologic pupilar dilatation of 5 mm in one or both eyes;
13. Complicated surgery expected;
14. Ocular surface disease (clinical symptoms) in one or both eyes;
15. Clinically significant dry eye as determined by the investigator's judgement in one or both eyes;
16. Anterior segment pathology that might increase intraoperative risk or compromise IOL stability;
17. Diabetic retinopathy;
18. Congenital ocular anomalies;
19. Chronic or recurrent inflammatory eye diseases;
20. Active infectious conjunctivitis, keratitis or uveitis in either eye within 30 days prior to surgery;
21. Subjects who may be expected to require a combined or other surgical procedure in either eye;
22. Pregnant, lactating or, if able to bear children, unwilling to use medically acceptable birth control over the course of the study;
23. Concurrent or previous (within 30 days) participation in another drug or device investigation;
24. Systemic medications that may confound the outcome or increase the risk to the subject in the opinion of the investigator (tamsulosin hydrochloride (Flomax) or other medications with similar side effects (floppy iris syndrome);
25. Subjects with conditions that increase the risk of zonular rupture during cataract extraction procedure that may affect the postoperative centration or tilt of the lens;
26. Subjects who are expected to require retinal laser treatment;
27. Patients showing contraindications as listed in the current Instructions for use (IFU);
28. Unsuitable for study participation for any other reason, as determined by Investigator's clinical judgment (reason to be documented on eCRF).

        In addition to above mentioned in- and exclusion criteria, subjects shall be discontinued
        when certain conditions are present at the time of surgery, including:
          -  zonular instability;
          -  need for iris manipulation;
          -  capsular fibrosis or other opacity; and
          -  inability to fixate IOL in desired position. In such cases, the subject shall be
             followed until the condition has stabilized.
