Contact probe for the delivery of laser energy

A laser treatment method for treating an eye by reducing intraocular pressure, the method comprising:

• positioning a tip of a laser probe in contact with a surface of the eye so that the tip of the probe is posterior to a limbus of the eye by a desired distance;
• sweeping the tip of the probe across the surface of the eye in an arc motion while the tip of the probe is maintained at the desired distance posterior to the limbus of the eye;
• delivering pulsed laser energy toward a first treatment region of the eye posterior to the limbus while the tip of the probe is swept across the eye and maintained in contact with the surface of the eye;
• repositioning the tip of the probe to another position posterior to the limbus of the eye by the desired distance and circumferentially offset from the first treatment region about an optical axis of the eye;
• and
• delivering pulsed laser energy toward a second treatment region of the eye with the tip of the probe in contact with the surface of the eye while sweeping the tip of the probe across the eye in the arc motion, wherein an aggregate amount of the pulsed laser energy reduces intraocular pressure of the eye.
