  • Patent number: 11779739
    Abstract: A customizable drug delivery system and method utilizing a laser pattern generator (LPG) to define application of a drug delivery payload (DDP) contained within a drug delivery device (DDD) to a drug delivery target (DDT) is disclosed. A computer control device (CCD) supervises the LPG to select a drug payload pathway (DPP) from a drug pathway database (DPD) and writes the selected DPP to the DDD. This pathway patterning process (PPP) modifies the hydrophilic properties of the DDD and enables the DDD to selectively attract and absorb the DDP. The DDD is then injected with the DDP or exposed for drug exposure time (DET) by the CCD and DPD during which the DPP written to the DDD absorbs a controlled amount of DDP. The DDD when subsequently inserted into a drug delivery target (DDT) delivers the DDP to the DDT under controlled delivery rates defined by the DPP and the DET.

  • Publication number: 20210369444
    Abstract: A system/method allowing hydrophilicity alteration of a polymeric material (PM) is disclosed. The PM hydrophilicity alteration changes the PM characteristics by decreasing the PM refractive index, increasing the PM electrical conductivity, and increasing the PM weight. The system/method incorporates a laser radiation source that generates tightly focused laser pulses within a three-dimensional portion of the PM to affect these changes in PM properties. The system/method may be applied to the formation of customized intraocular lenses comprising material (PLM) wherein the lens created using the system/method is surgically positioned within the eye of the patient. The implanted lens refractive index may then be optionally altered in situ with laser pulses to change the optical properties of the implanted lens and thus achieve optimal corrected patient vision. This system/method permits numerous in situ modifications of an implanted lens as the patient's vision changes with age.

  • Patent number: 10576704
    Abstract: A system/method allowing personalized ex vivo customization of a generic ophthalmic lens blank (OLB) or ophthalmic lens with known diopter (OKD) based on localized field-measured patient characteristics is disclosed. The OLB is composed of a clear material that contains an ultraviolet (UV) absorbing compound. The refractive index of a portion of the clear material may be customized by spatial modification (CSM) of its refractive index via the use of pulsed laser radiation (PLR). The customization of clear material (i) creates a lens which cannot be created otherwise, or (ii) eliminates the need for remote laboratory fabrication of a customized intraocular lens (IOL) for the patient. The OLB is retained within a secured lens container (SLC) providing for precise physical orientation of the OLB haptics and OLB lens structure with respect to the application of PLR to the OLB.

  • Patent number: 10495900
    Abstract: A system/method allowing personalized ex vivo customization of a generic ophthalmic lens blank (OLB) or ophthalmic lens with known diopter (OKD) based on localized field-measured patient characteristics is disclosed. The OLB is composed of an acrylic material that has been infused with an ultraviolet (UV) absorbing compound rendering it amenable to customized spatial modification (CSM) of its refractive index via the use of pulsed laser radiation (PLR). The CSM of refractive index eliminates the need for remote laboratory fabrication of a customized intraocular lens (IOL) for the patient. The OLB is retained within a secured lens container (SLC) providing for precise physical orientation of the OLB haptics and OLB lens structure with respect to the application of PLR to the OLB. The SLC contains a lens filler material (LFM) covering the OLB and is hermetically sealed after the OLB has been positioned within the SLC interior and prior to sterilization of the SLC+OLB combination.

  • Patent number: 10492955
    Abstract: An ophthalmic laser treatment system and method providing for a liquid optical interface (LOI) with a patient eye surface (PES) using an elliptical ocular suction ring (OSR) is disclosed. A disposable ocular patient interface (OPI) provides for simultaneous differential vacuum mating of the PES, OSR, OPI, and an optical window retainer (OWR). The PES, OSR, OPI, and OWR form an enclosed volume in which liquid may be interjected to cover the PES during laser treatment. A vacuum suction pump (VSP) provides controlled vacuum to the OPI ensuring proper differential vacuum mating (DVM) between the PES, OSR, OPI, and OWR during laser treatment. The OWR connects to a laser objective bracket (LOB) via an ocular force sensor (OFS) and an optical separator bracket (OSB). The OFS senses applied pressure to the PES and provides data to a computerized control device (CCD) that limits applied pressure to the PES during laser treatment.

  • Patent number: 9925621
    Abstract: A system/method allowing intraocular lens (IOL) fabrication using a femtosecond laser is disclosed. The system and method generate a stream of pulses at a rate of at least 1 million pulses per second and a pulse length of 300 femtoseconds or less to sculpt a polymeric material blank (PMB) to form an IOL. The high repetition rate and short pulse length combine to permit IOL fabrication in less than 10 minutes. During this fabrication procedure a lens may be formed within the IOL by incorporating a refractive index shaping (RIS) structure within the IOL. Additionally, IOL haptics may be formed during this IOL formation process. This combination of physical feature generation and RIS structure generation permits per-patient customization of the IOL as it relates to sphere, cylinder, asphericity, multifocality, and/or higher optical aberrations (HOAs).
