Myopia
Cambridge Anti-Myopia Trial: Accommodation Training and Aberration Control in Myopia Development
We have identified focussing problems related to myopia getting worse. Our trial uses optical and orthoptic interventions that correct the focussing problems to see if this retards myopia progression.

- NCT00317551
- Testing
- Aberration controlled contact lens, Vision training

- United Kingdom
- Volunteers
- 200 people, healthy volunteers welcome
