  • Patent number: 9532708
    Abstract: An electronically controlled fixation light system is described for ophthalmic systems. The ophthalmic system can include an ophthalmic imaging device that generates an image of a portion of an imaged eye, a fixation light controller that includes an input module, configured to receive an input in relation to the image generated by the ophthalmic imaging device, and a control signal generator that generates an electronic fixation light control signal in response to the received input, and a fixation light source, configured to receive the fixation light control signal, and to generate a fixation light according to the received fixation light control signal. A surgeon can image a portion of an eye with the imaging device, determine a misalignment of the imaged eye relative to the imaging device based on the image, and control the fixation light with an electronic control signal to reduce the determined misalignment.

  • Patent number: 9301878
    Abstract: A patient interface for an ophthalmic system can include an attachment module, attachable to the ophthalmic system, and a contact module, configured to accommodate a viscoelastic substance between the patient interface and a procedure eye. The viscoelastic substance can include a fluid, a liquid, a gel, a cream, an artificial tear, a film, an elastic material, or a viscous material. The refractive index of the viscoelastic substance can be within a range of approximately 1.24-1.52 at an operating wavelength of the ophthalmic system. The patient interface can further include input ports, output ports, and a suction system. It can be an integrated design or a multi-piece patient interface. The viscoelastic substance can be provided by injection, on the cornea, at the contact module, or in a space bounded by soft elastic films or membranes, such as in a bag.

  • Publication number: 20150297403
    Abstract: A system and method of resecting corneal tissue for transplantation is disclosed. In each of the recipient cornea and the donor cornea, an annular incision is made at a predetermined incision depth. A first sidecut incision is made in each cornea, running from the outer periphery of the annular incision to one of the anterior corneal surface or the posterior corneal surface. The first sidecut incision forms an acute angle with the annular incision. A second sidecut incision is also made in each cornea, running from the inner periphery of the annular incision to the other of the anterior corneal surface or the posterior corneal surface. The second sidecut incision forms an acute angle with the annular incision. The combination of the incisions in each cornea resects corneal tissue from the recipient cornea and donor tissue from the donor cornea. The donor tissue is grafted into the recipient cornea.

  • Publication number: 20140371771
    Abstract: A system and method for resecting and transplanting corneal tissue is disclosed. In a recipient cornea, a resection depth from the anterior surface of the recipient cornea is determined based upon a biomechanical model of the recipient cornea. A resection incision for resecting a posterior portion of the recipient cornea is made at the resection depth. Preferably, the incision is made using a surgical laser. Optionally, a contact lens may be placed against the anterior surface of the recipient cornea, wherein the shape of the anterior surface is conformed to the shape of the contact lens.
