Patients report high satisfaction with PureSee IOL

WASHINGTON — Patients who received the Tecnis PureSee extended depth of focus IOL had a high tolerance to residual refractive error, according to a study.At the American Society of Cataract and Refractive Surgery meeting, Vance Thompson, MD, presented data from a prospective, bilateral implant study that compared the Tecnis PureSee IOL extended depth of focus (EDOF) IOL (Johnson & Johnson, 113 patients) with a monofocal control IOL (Tecnis model DCB00, Johnson & Johnson, 110 patients). Key study endpoints at 6 months included binocular defocus curve visual acuity, absolute spherical

AI Summary

Quick Take

Data presented at ASCRS shows that the Tecnis PureSee extended depth of focus (EDOF) IOL provides patients with a high tolerance to residual refractive error compared to standard monofocal lenses. In a 6-month prospective study of over 220 patients, the PureSee IOL demonstrated strong visual performance across the defocus curve, suggesting a more forgiving refractive target for surgeons.

Why It Matters

Achieving perfect emmetropia is the primary goal of refractive cataract surgery, but residual refractive error remains a common reality that can lead to patient dissatisfaction with premium lenses. The Tecnis PureSee aims to bridge the gap between monofocal predictability and EDOF range, specifically addressing the sensitivity to 'missed' targets that can plague other presbyopia-correcting designs. If these lenses are truly more tolerant of minor refractive surprises, they could significantly reduce the need for post-operative laser enhancements and improve outcomes for a broader patient base.

Key Findings

Patients implanted with the Tecnis PureSee EDOF IOL exhibited a high tolerance to residual refractive error at the 6-month follow-up.
The study compared 113 patients receiving the PureSee IOL against a control group of 110 patients receiving the Tecnis DCB00 monofocal IOL.
Key study endpoints included binocular defocus curve visual acuity and absolute spherical equivalent outcomes.
The PureSee IOL demonstrated high patient satisfaction levels alongside its extended range of vision performance.

Practice Implications

Surgeons may consider the Tecnis PureSee for patients who desire a broader range of vision but have ocular characteristics where hitting a perfect plano target is less certain. The reported tolerance to residual refractive error suggests this lens could be a more forgiving EDOF option, potentially lowering the barrier for premium lens candidacy in a general cataract population.

What's Next

As this data from the ASCRS meeting is integrated into clinical practice, clinicians should watch for further peer-reviewed details regarding the specific dysphotopsia profile and contrast sensitivity of the PureSee. Long-term data will be essential to confirm if this refractive tolerance translates to fewer secondary interventions over time.
