Who may be able to join
AI generated eligibility summary. Written by an AI model from the official source data and checked on a sample basis. It can contain mistakes, so confirm anything important against the original source. How we use AI
Who might be able to join this trial:
- Adults aged 18 or older who have been diagnosed with primary open-angle glaucoma (a common type of glaucoma) and whose eye pressure was recorded as higher than 21 mm Hg before treatment started, as shown in their medical records.
- Adults aged 18 or older diagnosed with a type of glaucoma called normal-tension glaucoma, where the average daily eye pressure measured before starting any treatment was higher than 21 mm Hg, as shown in their medical records.
- Adults aged 18 or older with a condition called ocular hypertension, meaning eye pressure above 21 mm Hg but without signs of glaucoma damage to vision or the optic nerve, and with no other eye conditions that could be causing the raised pressure.
- Adults aged 18 or older with open-angle glaucoma showing typical signs of glaucoma-related damage to the optic nerve and to the field of vision.
- Adults aged 18 or older with open-angle glaucoma in one or both eyes, currently using eye drop medications to manage their condition, who have been recommended for a specific type of glaucoma surgery involving a small device called iStent inject W — either on its own or combined with cataract surgery, without having had any previous eye surgery.
- In cases where both eyes are affected, both eyes from the same person may be included in the trial one after the other.
- For the control group only: people currently using eye drop medications to lower eye pressure who also need cataract surgery.
Who may not be able to join:
- People under 18 years of age.
- People whose vision problems are caused by conditions other than glaucoma, or who have specific types of glaucoma such as angle-closure glaucoma or neovascular glaucoma.
- People with a history of eye injury, retinal disease, eye inflammation, laser eye treatment, or secondary glaucoma (glaucoma caused by another condition).
- People whose best-corrected vision (with glasses or lenses) is below a certain level, or whose lens prescription is stronger than 6 diopters (confirm with trial site).
- People who have had previous eye surgery, unless it was cataract surgery performed at least 6 months before joining the trial.
