PureSee EDOF Versus ZCB00 Monofocal IOLs in Mild-to-Moderate Glaucoma

November 2, 2026 updated by: Mann Eye Institute

Clinical Outcomes, Contrast Sensitivity, and Patient Satisfaction Following Bilateral PureSee EDOF Versus ZCB00 Monofocal IOL Implantation in Patients With Mild to Moderate Primary Open-Angle Glaucoma: An Ambispective Investigator-Initiated Trial

This study is a single center, ambispective study of visual outcomes after successful bilateral cataract surgery in patients with mild to moderate primary open-angle glaucoma (POAG). Two cohorts are compared: patients with bilateral implantation of the TECNIS PureSee non-diffractive extended depth of focus intraocular lens (EDOF IOL) and patients with bilateral implantation of the TECNIS ZCB00 monofocal IOL.

Study Population

Patients aged 45 years and older who underwent bilateral cataract surgery with bilateral implantation of either PureSee EDOF or TECNIS ZCB00, with bilateral mild or moderate primary open-angle glaucoma.

Description

Inclusion Criteria:

Age ≥45 years. Prior bilateral cataract surgery with bilateral implantation of either PureSee EDOF or TECNIS ZCB00 on or after March 12, 2026.

Intended postoperative refractive target between plano and -0.50 D in each eye. No intentional monovision. Bilateral mild or moderate POAG according to AAO ICD-10 staging criteria. Reliable glaucoma visual field available within approximately 18 months before cataract surgery or study enrollment, when available.

Reliable optical coherence tomography examination within 6 months. Adequately controlled IOP and clinically stable glaucoma in the investigator's opinion.

Prior SLT is permitted. Concurrent MIGS at the time of cataract surgery is permitted when clinically indicated at the discretion of the treating surgeon.

Ability to complete the study-specific examination and questionnaires. Study visit occurring 3-18 months following second-eye cataract surgery.

Exclusion Criteria:

Severe POAG or glaucomatous visual field loss involving fixation. Secondary glaucoma, including pseudoexfoliative, pigmentary, angle-closure, neovascular, or uveitic glaucoma.

Glaucoma surgery other than eligible concurrent MIGS that may materially influence study outcomes.

Corneal pathology or irregular astigmatism affecting visual outcomes. Prior corneal refractive surgery. Macular or neuro-ophthalmic disease affecting visual function. Other ocular pathology expected to limit postoperative CDVA to worse than 20/30.

Inability to obtain reliable visual field testing when required for glaucoma characterization.

Intentional monovision. The principal investigator reserves the right to declare a patient ineligible or non-evaluable based on medical evidence that indicates they are unsuitable for the trial.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Distance visual acuity - binocular distance-corrected visual acuity (DCVA)
Time Frame: 3 to 18 months following second-eye cataract surgery

Binocular distance-corrected visual acuity measured at the single study visit occurring 3 to 18 months following second-eye cataract surgery.

3 to 18 months following second-eye cataract surgery

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Intermediate visual acuity - binocular distance-corrected intermediate visual acuity (DCIVA)
Time Frame: 3 to 18 months following second-eye cataract surgery

Binocular distance-corrected intermediate visual acuity at 66 cm measured at the single study visit occurring 3 to 18 months following second-eye cataract surgery.

3 to 18 months following second-eye cataract surgery

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Contrast sensitivity - binocular, distance-corrected, photopic CSV-1000 contrast sensitivity without glare
Time Frame: 3 to 18 months following second-eye cataract surgery

CSV-1000 contrast sensitivity at spatial frequencies of 3, 6, 12, and 18 cycles per degree, binocular, distance-corrected, photopic, without glare.

3 to 18 months following second-eye cataract surgery
Spectacle independence at distance, intermediate, and near
Time Frame: 3 to 18 months following second-eye cataract surgery

Patient-reported spectacle independence at distance, intermediate, and near.

3 to 18 months following second-eye cataract surgery
Quality of vision and dysphotopsias
Time Frame: 3 to 18 months following second-eye cataract surgery

Patient-reported quality of vision and dysphotopsias assessed with validated patient-reported outcome instruments including the AIOLIS Questionnaire.

3 to 18 months following second-eye cataract surgery
Assessment of IntraOcular Lens Implant Symptoms (AIOLIS) Questionnaire
Time Frame: 3 to 18 months following second-eye cataract surgery

The AIOLIS has 37 questions about symptoms, perceptions of general vision, and frequency of wearing glasses or contact lenses. Perceptions about general vision are asked on a 5 item scale (Poor, Fair, Good, Very good, Excellent). Poor is considered a worse outcome.
