摘要:
A gonioscopic viewing system is provided for diagnosis or laser treatment of the anterior chamber angle of a patient's eye. A first lens system (10) includes a concave posterior lens surface (2) with a shape substantially corresponding to the shaped of an average cornea (C) so that, when placed on a patient's eye, light rays originating at the anterior chamber angle and passing through the aqueous humor, pass through the cornea and the posterior lens surface of the first lens system and are directed by the first lens system toward an image forming system. An image forming system is optically aligned with the first lens system for capturing the light rays directed by the first lens system and focusses the light rays to form a real image of the anterior chamber angle outside of the patient's eye.

An ophthalmic laser treatment apparatus (1) includes: an aiming optical system (20) configured to irradiate an aiming beam to a patient's eye; a laser irradiation optical system (10) configured to irradiate a laser beam for treatment to the patient's eye; shift means (50) configured to make a shift of a focus shift position corresponding to a focus position of the laser beam to a posterior or anterior position with respect to a focus position of the aiming beam; selection receiving means (200) configured to receive an instruction to select any one of a plurality of treatment modes; and control means (60) configured to control operations of the ophthalmic laser treatment apparatus. The control means sets a value of a parameter related to irradiation of the laser beam, the parameter including a parameter related to the shift of the focus shift position, according to the treatment mode selected with the selection receiving means.
摘要:
Because vision loss in most forms of glaucoma is related to elevated IOP, most glaucoma treatment protocols are concerned with lowering IOP by increasing aqueous humor outflow. The invention utilizes electromagnetic radiation to create retraction in the iris tissue, thereby (a) reducing convexity and enlarging the drainage angle and thus the area of the anterior chamber, (b) reducing contact between the zonule fibers and the iris pigment epithelium, (c) applying greater tension to both the TM and uveoscleral outflow pathways, thereby enlarging those pathways and increasing outflow.
摘要:
In various aspects, the invention provides methods for treating ocular inflammation using copper chelating compounds, such as compounds other than D-penicillamine. In some embodiments, such compounds may be polyamines, such as triethylenetetramine or tetraethylenepentamine. For example, the present invention provides methods for treating inflammation secondary to ocular laser therapy.

摘要:
A method for altering iris pigmentation in a human, thereby altering perceived iris color of a first iris from a first iris color to a second iris color. The method comprises preselecting one or more than one laser capable of generating one or more than one laser beam which will selectively remove iris pigment of a first preselected pigment color from the first iris, and applying the one or more than one laser beam to a first iris of a first iris color to remove iris pigment of the first preselected pigment color.
