Comparison of Visual Outcomes and Patient Satisfaction in Mild to Moderate Glaucoma Patients Undergoing Cataract Surgery With EDOF Versus Monofocal IOLs
74 participantsStarted 2026-01-31
Plain-language summary
Cataract is the leading cause of reversible vision loss, while glaucoma remains the primary cause of irreversible blindness, often impairing contrast sensitivity (CS), glare tolerance, and dark adaptation. These visual challenges are particularly relevant when selecting intraocular lenses (IOLs) for glaucoma patients undergoing cataract surgery.
Monofocal IOLs are the safest and most commonly used option for glaucoma patients due to their optical simplicity and low incidence of photic phenomena, though they do not provide spectacle independence for near or intermediate vision. Multifocal IOLs (MFIOLs), while offering greater spectacle independence, are relatively contraindicated in glaucoma due to increased visual disturbances like glare and halos.
Extended Depth of Focus (EDOF) IOLs offer an intermediate solution, using advanced optics to provide a continuous range of vision and fewer photic disturbances than MFIOLs. EDOF lenses have demonstrated good uncorrected distance and intermediate visual acuity in patients with mild to moderate glaucoma, with promising CS outcomes and high patient satisfaction. However, findings on CS performance remain inconsistent across studies.
Given these considerations, this study seeks to determine whether EDOF IOLs can be a viable alternative to monofocal lenses in glaucoma patients, potentially expanding their options for spectacle independence without compromising visual quality. The trial, conducted at OMIQ (Barcelona), will directly compare an EDOF IOL and a monofocal IOL made from the same material to assess their effects on visual acuity, contrast sensitivity, and photic phenomena in this specific patient population.

Inclusion criteria:
* Patients of any sex aged 18 years or older willing to participate and sign the informed consent form.
* Clinically significant cataracts in both eyes.
* Patients clinically diagnosed of primary open angle glaucoma (POAG) in both eyes.
* Early to moderate POAG, as defined by a mean deviation in the Humphrey Visual Field Analyzer (HFA) no worse than ≤ -12 dB and worse ≥ -2 dB at least in one eye, using a 24-2 SITA standard strategy
* Two visual field tests without progression and stability of RNFL in Optical Coherence Tomography (OCT) thickness remaining same or less than 10 um in the previous 6 months, with pharmacologically controlled IOP in both eyes \<21mmHg.
* Potential for post-surgery monocular distance corrected visual acuity of ≤ 0.10 LogMAR.
* Normal corneal topography.
* Able to attend all study visits.
Exclusion criteria:
* Patients with uncontrolled glaucoma, defined as those with an IOP ≥21 mm Hg despite maximal medical therapy, requiring glaucoma surgery and/or laser in either eye in the next year.
* Pre-surgery refractive error requiring IOL implantation beyond the commercially available range.
* Patients with a not reliable visual field, a VFI ≤ 60% or defects of ≤ 10 dB in the 4 central points of the visual field.
Any other form of glaucoma (pseudoexfoliative, severe forms of pigmentary, primary angle closure glaucoma, etc.), ocular hypertension, zonular instability or possible intuitive lens decentration after surgery.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
