Methods for treating eye conditions
View Patent ↗Architectures and techniques for treating conditions of the eye, such as presbyopia, utilize sources of treatment energy, such as electromagnetic energy emitting devices, to implement non-corneal manipulations. According to these devices and methods, the sources of treatment energy are activated to direct energy onto parts of the eye, such as the conjunctiva and sclera, to treat presbyopia. The treatments can affect at least one property of the eye and enhance an accommodation of the eye.

a visualization fiber optic coupled to the electromagnetic energy outputting fiber optic tip, the visualization fiber optic being configured to enable visualizing through the visualization fiber optic as the electromagnetic energy outputting fiber optic tip imparts the one or more tissue treatments onto the one or more treatment areas of the sclera of the eye; and
