What is presbyopia surgical reversal with scleral expansion bands? This presbyopia treatment uses implants in the eye. You're familiar with corneal implants.
The sclera, the outer coat of the eyeball that forms the visible white of the eye and surrounds the optic nerve at the back of the eyeball, becomes less flexible with presbyopia. In surgical reversal of presbyopia with scleral expansion bands, the surgeon inserts four bands below the surface of the sclera. These bands increase the distance between the lens and the muscles that focus the lens, and may even augment the tension in the muscles focusing the lens. Since the muscles' loss of flexibility causes presbyopia, the implants seem viable presbyopia treatments from preliminary research studies.
However, as with any other new treatment, this presbyopia surgery improves vision for some patients but not for others. Also, the bands may erode or expand, causing infection and/or decreasing blood circulation in your eyes. Before considering this or any experimental presbyopia treatment, talk with your eye doctor.
