In certain embodiments, an ophthalmic surgical system for creating a lenticule in the cornea of an eye comprises controllable components (including a laser source and a scanner) and a computer. The laser source generates a laser beam, and the scanner directs the focal point of the laser beam. The computer determines a lenticule design for the lenticule having a posterior side and an anterior side. Either the posterior side or the anterior side has a central portion and a peripheral portion. The lenticule design is formed using a major lenslet and a minor lenslet, where the major lenslet is designed to correct to emmetropia. The lenticule design is formed by subtracting the minor lenslet from the major lenslet, where the subtraction of the minor lenslet yields the central portion. The computer instructs one or more of the controllable components to create the lenticule.

Systems and methods for creating a lenticule for presbyopia

According to certain embodiments, an ophthalmic surgical system for treating presbyopia comprises controllable components and a computer. The controllable components comprise a light source that generates a light beam and a scanner that directs a focal point of the light beam. The computer determines an ablation profile to remove tissue from a central region and a peripheral region of a cornea of a first eye of a pair of eyes. The ablation profile is designed to remove tissue from the central region to yield a protrusion to provide for near-vision, and to remove tissue from the peripheral region to correct to emmetropia.

Ablation systems and methods for treating presbyopia

A device for the recognition of caries, plaque or bacterial infection on teeth, which includes a light source for generating an excitation radiation which is to be directed onto a tooth to be investigated and producing an fluorescence radiation at the tooth. Also included is a detection device for detecting the fluorescence radiation of the tooth, and a spectral filter arranged in front of the detection device, wherein the wavelength of the excitation radiation emitted from the light source lies within the range of between 640 and 670 nm.
