1. A system for providing a therapeutic treatment to a patient's eye, the system comprising:
an aiming beam source configured to transmit an aiming beam along an aiming beam path;
a treatment beam source configured to transmit a treatment beam along a treatment beam path extending non-coaxially relative to the aiming beam path;
a convex lens disposed between the patient and the treatment beam source;
a concave lens disposed between the treatment beam source and the aiming beam source; and
a processor coupled to the aiming beam source and the treatment beam source, the processor being configured to:
direct the aiming beam through the concave lens configured to diverge the aiming beam around the treatment beam source such that only a portion of the aiming beam is blocked by the treatment beam source prior to directing the aiming beam through the convex lens configured to focus the aiming beam onto retinal tissue of the patient's eye to define a visible treatment boundary on the retinal tissue; and
direct the treatment beam onto retinal tissue of the patient's eye at a first treatment spot disposed within the treatment boundary formed by the aiming beam.
