Abstract: A system and a method may be provided relating to the iris of an eye based on three-dimensional image data acquired by an optical coherence tomography.

Abstract: Methods and systems are described for a rapid and sustainable change in the pigment melanin content of melanocytes of the iris stroma, thereby to change the color of the eye. Also described are nanoparticle compositions for lightening or darkening the pigmented tissues or treating a pigmented tissue disease.

Abstract: A temporary transnasal lacrimal insert is used in a surgical procedure for improving drainage from a patient's lacrimal sac to his or her nasal cavity. The insert includes a tubular member with a proximal end and an enlarged distal end. The insert also includes an attachment element about which ends of a silastic tube can be fastened. In the procedure, a hole is created extending from the lacrimal sac into the nasal cavity using surgical techniques or a laser probe. Then, opposite ends of a silastic tube are introduced through the patient's upper and lower puncta, through the patient's upper and lower canaliculi, through the lacrimal sac, through the hole, and into the nasal cavity. The ends of the silastic tube are then threaded through the passage in the insert.

The ends of the tube are then threaded through the passage in the insert. The insert is then placed from the nasal cavity into the hole by forcing the proximal end of the insert through the hole and into the lacrimal sac, and abutting the enlarged distal end, which is larger than the hole, against a surface in the nasal cavity surrounding the hole.
