Clinical trials: Intraocular Lens Rotation
Posterior Capsule Opacification, Pseudophakia
IOL Position and Refractive Change After Nd:YAG Laser Posterior Capsulotomy
After cataract surgery, the thin natural membrane that holds the artificial lens in place can slowly turn cloudy. This is called posterior capsule opacification. It makes vision blurry and can cause glare.
- Conditions
- Posterior Capsule Opacification, Pseudophakia, Refractive Errors
- Trial name
- YAG-IOL-POS (NCT07802145)
- Testing
- Nd:YAG laser posterior capsulotomy, Anterior segment swept-source OCT, Swept-source optical biometry
