LaserACE® Proposed Mechanism of Action

How LaserACE® Works

Presbyopia results from a gradual decrease in the power of accommodation.

Figure 1:

  • In a young eye (25 year old), the sclera moves with accommodative force of the ciliary muscles.
  • In an aging eye (50 year old), the sclera is less pliable and resists the movement of accommodation that the ciliary muscles exert on the lens. 
  • LaserACE® improves the power of accommodation by rejuvenating the rigid sclera in the aged eye in specific regions over the ciliary muscles making it pliable again.
  • After LaserACE® the sclera moves with the ciliary muscles during accommodation increasing the power of the force they can exert on the lens.
  • LaserACE® improves focusing power of the lens for near and intermediate vision without affecting distance vision.
