Abstract: A light source for providing a light beam to an ophthalmic instrument with a predetermined spectral content, with a first light source device (1) for providing a first beam of light (9a) along a first optical axis and with a radiation opening angle (α). A mirror body (6) has a mirror aperture (6a) aligned with the first optical axis for allowing the first beam of light (9a) to partially pass, and a mirror surface (6b) adjacent to the mirror aperture (6a) for directing radiation from the first beam of light (9a) back to the layer of wavelength conversion material (1a). Also, a second light source device (7) may be present for providing a second beam of light (9a) along a second optical axis, and a dichroic mirror (3) for combining the first beam of light (9a) and the second beam of light (9b) into a combined beam of light (9c).

Abstract: A fluid level indicator (50) for indicating the fluid level in an ophthalmic irrigation and/or aspiration system comprises a chamber (10) configured for holding a surgical fluid (F). The chamber (10) comprises at least one fluid port (72; 74) and a pressure port (71) for connection to a pressure source (20). A channel (140) extends from the chamber (10). The fluid level indicator (50) comprises a float (160) having a float body (162) disposed within the chamber (10) and a stem (164) extending from the float body (160) into the channel (10). The float body (160) is configured to move with the level of fluid within the chamber (10), thereby moving the stem (164) along the channel (140) extending from the chamber (10). The position of the stem (164) within the channel (40) indicates the fluid level within the chamber (10).

Abstract: A forceps comprising a first jaw and a second jaw arranged along a longitudinal axis of the forceps for relative movement toward and away from one another. The first and second forceps jaws have respective first and second jaw surfaces facing each other. The first and second jaw surfaces have a serrated surface texture at least on a distal part thereof. A serration direction of the serrated surface texture is at an angle which is non-perpendicular to the longitudinal axis, resulting in additional profile structure elements at a tip portion surface, allowing to handle and manipulate fine tissue materials such as membranes in an eye.
