New treatment option for Cataract and IOL Surgery
Official title Head-to-Head Comparison of Five Enhanced Depth of Focus IOLs and One Monofocal IOL
ClinicalTrials.gov ID: NCT07051720
What this study is testing
- What it's testing
- Study Goal The goal of this clinical trial is to compare how well four different types of artificial lenses (called intraocular lenses or IOLs) help people see after cataract surgery. The main questions it aims to answer are: Which lens gives the best vision at different distances (far, middle, and close)?
- Which group you join is decided by chance.

Who can take part
Ages 22 to 85
You may be able to join if
- Bilateral implantation of the same intraocular lens (IOL) model
- Expected postoperative best-corrected distance visual acuity (BCDVA) of 0.8 (decimal) or better
- Regular corneal astigmatism less than 1 diopter
You likely can't join if
- Endothelial cell density \< 2,000 cells/mm²
- Required IOL power for emmetropia falls outside the available range of +10.0 D to +30.0 D
- Pupillary abnormalities
- Intraocular inflammation
- Recent ocular trauma or ocular surgery that is unresolved/unstable, or which may impair visual outcomes or increase patient risk
- History of corneal refractive surgery (e.g., LASIK, LASEK, PRK)
