A system for staking a haptic to an optic to form an intraocular lens using a laser beam operating near the infrared range with a coaxial aiming laser beam operating in the visible range. A portion of the haptic is inserted into the optic through a radial bore and is exposed through an axial bore spanning from the optic upper surface to the radial bore. The coaxial laser beams are collimated and then focused using a microscope objective through the axial bores, onto the exposed haptic. Aiming of the coaxial beams onto the optic and haptic is aided by the use of a magnifying CCD camera positioned with its optical axis at a 45.degree. angle to the optic horizontal plane. The coaxial lasers, which are typically focused to a minor diameter which is greater than or equal to the inner diameter of the axial bore, make contact with the exposed haptic. Consequently, the haptic is melted and is then allowed to cool, coalescing into a bead staking the haptic to the optic.

Haptic attachment system for intraocular lenses using diode laser

A novel method and a novel apparatus therefor are described for detecting and measuring a predetermined immunochemical substance, for example, an antigen, an antibody, a hapten, or certain low molecular weight substance. The detection and measurement of an immunochemical substance using the method and apparatus of the invention involves providing for the agglutination of a suspension of particles in a sample, or color intensity of solutions by which, using the apparatus of the invention to determine certain electromagnetic radiation properties of the sample, the presence and amount of the immunochemical substance can be determined.

Apparatus for determining immunochemical substances

An immunoassay based on the agglutination or the agglutination inhibition of a suspension of immunologically coated particles by the sample. Measurements are made with an apparatus having means for providing electromagnetic radiation at wavelengths equal to or less than the mean diameter of the particles and in a range of at least about 100 nm. The apparatus also includes means for measuring, at a predetermined angle, a portion of the radiation transmitted through a cuvette containing the reaction mixture.
