Systems and processes are described relating to laser-based ophthalmic intervention technologies and, more specifically, to techniques for delivering reproducible amounts of laser energy to create visible and sub-visible lesions on an eye. The subject technology may provide a user with the ability to adjust the amount of energy to be delivered to the eye tissue by selecting a single numerical value. In response, the system may adjust the power and/or duration of the laser treatment beam pulse according to an operating curve determined by the system.
