After having signed and dated the patient informed consent form, patients will undergo an initial ophthalmic examination. The CLS will be placed on both eyes for a baseline 24-hour IOP pattern recording session (S1), within 2 weeks preceding the laser treatment. Patients will remain ambulatory and will be encouraged to follow a schedule as close to his/her usual lifestyle as possible. At hour 24, patients will return to the clinic, the device will be removed and a final ophthalmic examination will be conducted. Patient diary will be collected and concomitant medication will be reported.
