A contact lens for presbyopia and keratoconus
Part of Eyes & vision clinical trials.
This trial tests a special contact lens that uses a tiny opening to improve vision for people with presbyopia (age-related reading blur) or with keratoconus (a cone-shaped cornea). The lens aims to make both near and distant objects clearer without surgery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 years or older.
- You either have keratoconus (but no reading glasses needed) or you need reading glasses for presbyopia without any corneal surface problems.
- Your cornea must be stable – for example, no recent cross-linking or stitches.
- You must be willing to remove contact lenses (all types) for at least 48 hours before each clinic visit.
- You must be able to read Dutch.

This study tests whether using advanced imaging can help make scleral contact lenses fit better for people with certain eye conditions. If you have keratoconus, an irregular cornea after a transplant, or severe dry eye and have struggled with other lens types, this may be for you.
This trial tests two different laser-based procedures to treat keratoconus, a condition that weakens and bulges the cornea. The goal is to see which approach better strengthens the eye and improves vision.
This trial tests a specific cataract replacement lens to see how safe it is and how well it improves vision. If you have cataracts in both eyes and are good candidate for cataract surgery, this lens may help you see more clearly after surgery.
This study tests two types of soft contact lenses that help with both distance and near vision. If you wear multifocal lenses or use a monovision setup, this trial may help find which lens works better for your daily activities.
This trial tests a new treatment called the VIS Opti-K™ System to help people with presbyopia (age-related trouble seeing up close) see better without glasses. It uses a special lens to improve near vision in one eye while keeping distance vision clear.
This study tests two types of implantable lenses that correct astigmatism (blurry vision from an irregularly shaped cornea). You keep your own natural lens, and the new lens is placed in front of it—no laser or lens removal needed. The goal is to see which lens works better and is safer.
