New lens aims to sharpen vision for LASIK patients with cataracts
NCT ID NCT07260695
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how well a new type of cataract lens works for people who had LASIK surgery in the past. Cataracts cause blurry vision, and this lens is designed to help with seeing clearly at all distances. The study will involve 30 adults aged 50 and older who need cataract surgery in both eyes. Researchers will measure vision quality and how satisfied patients are after the procedure.

Exclusion Criteria: Subjects with ANY of the following conditions on the eligibility exam may NOT be enrolled into the trial. 1. Established ocular pathology, including: glaucoma (except glaucoma suspects), uveitis, and clinically-significant retinal pathology affecting the macula (with visual acuity worse than 20/25) 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. Contact lens use during the active treatment portion of the trial. 7. Irregular astigmatism. 8. Corneal irregularities potentially affecting visual acuity (i.e., keratoconus, corneal opacities 9. History of chronic intraocular inflammation. 10. History of retinal detachment. 11. Pseudoexfoliation syndrome or any other condition that has the potential to weaken the zonules. 12. Previous intraocular surgery. 13. Previous keratoplasty 14. Previous refractive surgery other than myopic LASIK or PRK (i.e., radial keratotomy, hyperopic LASIK, etc) 15. Severe dry eye. 16. Pupil abnormalities. 17. Subject who may reasonably be expected to require a secondary surgical intervention at any time during the study (other than YAG capsulotomy, i.e., LASIK). 18. Any clinically significant, serious, or severe medical or psychiatric condition that may interfere with the interpretation of study results. 19. 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. 20. Inability to focus or fixate for prolonged periods of time (e.g., due to strabismus, nystagmus, etc.) 21. Abnormal iris The principal investigator reserves the right to declare a patient ineligible or non-evaluable based on medical evidence that indicates the patient is unsuitable for the trial.
