  • Confocal laser method and device for measurement of optical properties of toric intraocular lenses
    Patent number: 10302528
    Abstract: Described are systems, devices, and methods related to a confocal laser method (CLM) for accurately measuring dioptric powers and other critical optical properties of intraocular lenses (IOLs), such as toric IOLs. Described test results demonstrate that the described CLM systems and methods can be used to measure the spherical equivalent and cylinder powers of toric IOLs with high accuracy. Furthermore, some described systems include a rotating rectangular slit aperture that can be used for precise differentiation of the two focal planes and isolation of the two focal points, and thus, for accurate measurement of the anterior cylinder axis of toric IOLs.
