  • Patent number: 11642244
    Abstract: A system for treating an eye includes a laser light source providing photoactivating light. The system includes a scanning system to receive the photoactivating light as a laser beam and to move the laser beam over a cornea treated with a cross-linking agent. The system includes a controller that provides control signal(s) to programmatically control the laser light source and the scanning system. The control signal(s) cause the laser beam to visit region(s) of the cornea more than once according to a scan pattern and expose the region(s) to the photoactivating light. The photoactivating light causes the cross-linking agent in the exposed region(s) to react with oxygen to generate cross-linking activity in the exposed region(s). The scan pattern causes a predetermined period of time to pass between visits by the laser beam to the exposed region(s), the predetermined period of time allowing oxygen in the exposed region(s) to replenish.

  • Patent number: 11253317
    Abstract: A laser can produce pulses of light energy for tissue-type selective ejection of a volume of the target tissue, and the energy can be delivered to a treatment site through a waveguide, such as a fiber optic waveguide. The incident laser energy can be absorbed within a volume of the target tissue with a tissue penetration depth and pulse direction such that the propagation of the energy from the tissue volume is inhibited and such that the target tissue within the volume reaches the spinodal threshold of decomposition and ejects the volume, for example without substantial damage to tissue adjacent the ejected volume. The pulses are set to be tissue selective.

  • Patent number: 11173067
    Abstract: An initial treatment pattern defining an initial volume of ocular tissue to be modified for treating glaucoma is designed. An initial laser treatment is delivered by scanning a laser beam across ocular tissue at an initial placement in the eye in accordance with the initial treatment pattern to thereby photo disrupt the initial volume of ocular tissue. A postoperative measure of intraocular pressure (IOP) is evaluated relative to an IOP criterion to determine if the treatment was successful. If the treatment was not successful, meaning the IOP criterion was not satisfied, then a subsequent treatment pattern that defines a subsequent volume of ocular tissue to be modified, and/or a subsequent placement in the eye is determined. A subsequent laser treatment is delivered by scanning a laser beam across ocular tissue at the subsequent placement within the eye in accordance with the subsequent treatment pattern to thereby photo disrupt the subsequent volume of ocular tissue.
