Abstract
A method for treating presbyopia by performing laser ablation of the sclera involves making incisions into the sclera which are filled in with material which is more elastic than the original scleral tissue when the incisions heal. Such incisions may be placed radially about the eye in the scleral region outside the limbus of the eye. The increased circumferential diameter and flexibility of the treated portion of the sclera, along with the overall greater volume of the eye, can allow for an increase in the accommodation which can be produced in the eye via the action of the ciliary muscles on the lens and front portion of the sclera. A method for modeling the resulting visual acuity as a linear and non-linear function.
