Which lens helps you see better after cataract surgery?
NCT ID NCT07385014
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at two different artificial lenses used during cataract surgery to see which one gives better vision at near, middle, and far distances. 80 adults with cataracts received one of the two lenses. The goal was to find out if one lens helps people see better without glasses after surgery.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Male or female, age 18 or older at the time of study enrollment. 2. Visually significant cataract in the study eye for which phacoemulsification cataract extraction and posterior chamber IOL implantation is indicated. 3. Projected postoperative CDVA 0.20 logMAR (Snellen 20/32) or better in the study eye, as determined by an Investigator's medical judgement. 4. Calculated spherical power targeted at emmetropia at distance in the study eyes. 5. Calculated IOL power between +5.0 - +34.0 D, inclusive, in both eyes. 6. Measured keratometric astigmatism less than 1.0 D if against-the-rule or 1.5 D if with-the-rule/oblique. 7. If wearing rigid gas permeable (RGP) contact lens in the study eye, willingness to discontinue lens wear for ≥ 21 days prior to preoperative biometry. 8. Availability, willingness, and sufficient cognitive awareness to return for study-required visits and comply with examination procedures. 9. Willingness to sign the IRB-approved informed consent form (ICF) for study participation. Exclusion Criteria: 1. Mature cataract in the study eye that is likely to prolong surgical procedure and/or lead to intraoperative complications prior to attempted IOL implantation. 2. Any visually significant intraocular media opacity other than cataract in the study eye (as determined by the investigator). Such opacities might include corneal scar or vitreous hemorrhage. 3. Abnormal corneal findings in the study eye (e.g. keratoconus, pellucid marginal degeneration, irregular astigmatism). 4. Any anterior segment pathology in the study eye that could significantly affect outcomes (e.g. chronic uveitis, iritis, aniridia, clinically significant corneal dystrophies, etc.) 5. Any condition in the study eye that could affect IOL stability (e.g. pseudoexfoliation, zonular dialysis, evident zonular weakness or dehiscence, etc.). 6. History of severe dry eye in the study eye that, in the judgement of the investigator, would impair the ability to obtain reliable study measurements. 7. History of serious corneal disease (e.g. herpes simplex, herpes zoster keratitis, etc.) in the study eye. 8. History of any clinically significant retinal pathology or ocular diagnosis in the study eye that could, in the investigator's best judgement, alter or limit final post-operative visual prognosis (e.g. diabetic retinopathy, ischemic disease, macular degeneration, retinal detachment, optic neuropathy, amblyopia, strabismus, aniridia, epiretinal membrane, etc.). 9. History of cystoid macular edema in either eye. 10. History of uveitis in either eye. 11. History of intraocular or corneal surgery in the study eye besides laser peripheral iridotomy (LPI), selective laser trabeculoplasty (SLT), or argon laser trabeculoplasty (ALT). 12. Uncontrolled glaucoma in the study eye (per Investigator judgement). 13. Current ocular infection in the study eye. 14. Presence of uncontrolled systemic disease that could increase operative risk (e.g. diabetes mellitus, mental illness, dementia, clinically significant atopic disease, etc.). 15. Planned concomitant ocular procedure during cataract surgery inclusive of glaucoma surgery e.g. MIGS or limbal relaxing incisions. 16. Unsuitable for study participation for any other reason, as determined by the Investigator's clinical judgement.
