Ophthalmic Surgical Instruments

An optical instrument either processes light waves that can enhance an image for viewing, or analyzes light waves that regulate one of a number of characteristic properties. Telescope is the first optical instruments were used for magnification of distant images, and microscopes used for magnifying very tiny images. These instruments have been greatly improved and stretched into other portions of the electromagnetic spectrum. The binocular device is generally a compact instrument for both eyes designed for mobile use. Ophthalmic instruments like Toric Marker and Pre-chopper are used to mark and chop the lens before implantation. Capsulotomy forceps are used to to tear the anterior capsule of the lens during cataract surgery. Camera could be considered AS optical instrument, with the pinhole camera and camera obscura being very simple examples of such devices.
