System And Method For Determining Dosimetry In Ophthalmic Photomedicine

A method of treating ophthalmic target tissue, comprising:

• generating a beam of light;
• delivering the beam of light to ophthalmic target tissue using a scanner unit for deflecting the beam of light;
• creating a dosimetry pattern of the beam of light on the ophthalmic target tissue for which at least one dosage parameter of the beam of light varies within the dosimetry pattern;
• capturing an image of lesions formed on the ophthalmic target tissue by the dosimetry pattern;
• selecting at least one dosage parameter for the beam of light in response to the captured image of lesions;
• and
• delivering the beam of light to the ophthalmic target tissue having the selected at least one dosage parameter.

A system for treating ophthalmic target tissue, comprising:

• a light source for generating a beam of light;
• a beam delivery unit for delivering the beam of light to ophthalmic target tissue, wherein the beam delivery unit includes a scanner unit for deflecting the beam of light;
• a controller for controlling at least one of the light source and the beam delivery unit to create a dosimetry pattern of the beam of light on the ophthalmic target tissue for which at least one dosage parameter of the beam of light varies within the dosimetry pattern;
• a visualization apparatus for observing lesions formed on the ophthalmic target tissue by the dosimetry pattern;
• and
• a user interface for receiving information about the observed lesions;
• wherein the controller is configured to control at least one of the light source and the beam delivery unit to then deliver the beam of light to the ophthalmic target tissue having at least one dosage parameter thereof selected in response to the received information.

• observing lesions formed on the ophthalmic target tissue by the dosimetry pattern;
• entering information about the observed lesions using a user interface that is connected to a controller that controls at least one of the light source and the beam delivery unit;
• selecting at least one dosage parameter for the beam of light in response to the entered information;
• and
• controlling at least one of the light source and the beam delivery unit using the controller to then deliver the beam of light to the ophthalmic target tissue having the at least one selected dosage parameter.
