A Prospective, Single-Arm Clinical Evaluation of Visual, Refractive, and Patient-Reported Outcomes Following Bilateral Implantation of the TECNIS PureSee™ Extended Depth of Focus Intraocular Lens
August 24, 2026 updated by: Vance Thompson Vision
Assess the visual, refractive, and patient-reported outcomes - including spectacle independence - of bilateral cataract surgery with implantation of the TECNIS PureSee extended depth of focus (EDOF) IOL in subjects with visually significant cataract in a real-world setting.

Participation Criteria
Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
Eligibility Criteria
Ages Eligible for Study
- Adult
- Older Adult
Accepts Healthy Volunteers
No
Description
Inclusion Criteria:
- Adults aged ≥40 years with bilateral visually significant cataracts electing to undergo cataract surgery
- Calculated IOL power within the available PureSee power range
- Both eyes targeted for plano (first minus recommended) in both eyes
- Preoperative corneal astigmatism ≤0.75 D for non-toric PureSee, or within the treatment range of the PureSee Toric platform
- Potential postoperative best-corrected distance visual acuity of 20/25 or better in each eye
- Willing and able to comply with the scheduled visits and study procedures
Exclusion Criteria:
- Prior intraocular or corneal refractive surgery in the operative eye(s)
- Irregular corneal astigmatism, keratoconus, pellucid marginal degeneration, or other ectatic disease
- Clinically significant macular pathology, advanced glaucoma with field loss, amblyopia, or any concurrent ocular condition that would limit BCVA at the discretion of the investigator
- Pupil abnormalities, zonular instability, pseudoexfoliation, or any condition predisposing to intraoperative or postoperative IOL instability
- History of ocular trauma or uveitis
- Uncontrolled systemic disease that in the opinion of the investigator would interfere with study participation or healing
