Switching glaucoma drops to preservative-free ZOLYMBUS
Part of Eyes & vision clinical trials.
This study tests whether switching from a standard glaucoma eye drop (which contains preservatives) to a preservative-free version called ZOLYMBUS can help with both eye pressure control and dry eye symptoms. If you have both glaucoma and dry eye, this switch might reduce irritation while keeping your pressure stable.

This study compares two versions of latanoprost eye drops—one that contains a preservative and one that is preservative-free. It aims to see how each version affects the eye’s “goblet cells,” which help keep the eye surface healthy.
This trial tests whether a new prescription eye drop called Qlosi improves the quality of life for people with presbyopia (age-related trouble seeing up close). You will use the drops regularly and answer questions about your vision and daily activities.
This study tests a new eye drop called PRO-190 to see if it's safe and comfortable for the eyes, comparing it to a common artificial tear (Systane Ultra). It is for healthy people and may help if you have dry or irritated eyes.
This study looks at whether certain glaucoma eye drops might help protect the nerve cells in your eye over time. If you've been using the same type of eye drop for a few years, researchers will review your past eye tests to see how your vision and eye health have changed.
This study tests whether insulin eye drops can safely help dry eye in people who also use eye drops for glaucoma. It may offer a new option if you have both conditions and your eye pressure is stable.
This study tests a new eye drop against an existing one to see which better lowers eye pressure in people with open-angle glaucoma or ocular hypertension. You may be able to join if you have high eye pressure in both eyes that needs treatment and you are at least 18 years old.
