Inclusion criteria

1. Age: 18 years and older. 2. Gender: Males and Females. 3. Uneventful bilateral lens extraction 4. Bilateral implantation of Synergy IOLs (toric and non-toric) by 5 anterior segment surgeons at Center For Sight (DWS, WJL, JWK, WLS, and JOD) and 1 surgeon at Carolina Eyecare Physicians (KDS) through the months of June to December 2021. 5. Willing and able to provide written informed consent for participation in the study. 6. Willing and able to comply with scheduled visit and study examination procedures. 7. At least 3 months postoperative from second eye IOL implantation. 8. Postoperative best corrected visual acuity of 0.2 logMAR (20/32 Snellen) or better in both eyes.

Exclusion criteria

1. Established ocular pathology, including: glaucoma (except glaucoma suspects), uveitis, and clinically-significant retinal pathology affecting the macula (with visual acuity worse than 20/32) and/or any other ocular findings that may, in the opinion of the investigator, affect vision. 2. Uncontrolled diabetes. 3. Use of any systemic or topical drug known to interfere with visual performance. 4. Any concurrent infectious/non-infectious conjunctivitis, keratitis or uveitis. 5. Clinically significant corneal dystrophy. 6. Irregular astigmatism. 7. History of chronic intraocular inflammation. 8. Previous intraocular surgery. 9. Previous keratoplasty 10. Previous refractive surgery. 11. Severe dry eye 12. Pupil abnormalities 13. Any clinically significant, serious or severe medical or psychiatric condition that may interfere with the interpretation of study results. 14. Participation in (or current participation) any ophthalmic investigational drug or ophthalmic device trial within the previous 30 days prior to the start date of this trial. 15. Best-corrected distance visual acuity worse than 20/32 in each eye. 16. Inability to focus or fixate for prolonged periods of time (e.g., due to strabismus, nystagmus, etc.) 17. Abnormal iris 18. Patients who had a complication during cataract surgery, which could include ruptured zonules, torn capsule, or vitrectomy.
