Posted on: 14 August 2019 by 50connect Promotions

For this study, researchers recruit candidates with presbyopia (age-related near vision loss).

The study evaluates the use of corneal tissue to correct near vision loss to eliminate the need for reading glasses or contact lenses. If you are interested in registering as a candidate for this study, please complete the application form via

Presbyopia is also known as age-related near vision loss resulting in reading issues.

People with presbyopia: 

  • experience a gradual loss of the ability to focus on close objects or small print;
  • typically develop reading problems as of the age of 45;
  • find themselves struggling to read smartphone messages, menus, price tags, …;
  • start to hold reading material at arm’s length;
  • who don't already wear glasses or contact lenses, may choose to wear reading glasses all the time or only when necessary to magnify objects close to them. The vision correction prescriptions begin with plus signs (like +2.50).

What is the goal of the clinical study?

Presbyopia can be corrected with reading glasses or contact lenses. As it might have an impact on someone's lifestyle, surgery might be considered to correct vision.

The objective of this clinical study is to evaluate the safety and effectiveness of implantation of the corneal tissue (allografts) for improving near vision in people with presbyopia. This correction intends to eliminate the need for glasses or contact lenses.

Which study sites within the UK participate in the study?

  • Centre For Sight, Oxshott or East Grinstead
  • Queen Victoria Hospital, East Grinstead
