  • Patent number: 7101364
    Abstract: A method and apparatus for intrastromal refractive surgery is disclosed wherein tissue at selected locations within the stroma of the cornea is photoablated using a pulsed laser beam. The apparatus includes an optical system for forming a shaped laser beam having a waist at a predetermined distance from the optical system. The pulse duration and pulse energy of the laser beam are selected to cause ablation to occur in front of the waist (i.e. between the waist and the optical system). To achieve this, a pulse energy is used that exceeds the minimum pulse energy required for ablation at the waist. By ablating in front of the waist, a relatively large ablation zone (per pulse) is created (compared to ablation at the waist). Furthermore, while the laser is scanned through the cornea to effectuate a refractive change, the optical system maintains a uniform waist for the laser beam.

  • Patent number: 7097639
    Abstract: Method and apparatus to treat unwanted dermatological conditions on a specific area of the body. The area of treatment is exposed to a specific pattern of multi-wavelength light which may have an added infusion of a particular wavelength from a unique non-collimated laser rod optical insertion. The light is generated by specific gas mixture multiple flashlamps that allow simultaneous, overlap, or consecutive firing with quasi-logarithmic spacing between pulses. Pre/Post low level optical heating increases lesion temperature to optimize pulsed treatment. The optimum fixed specific wavelength distribution pattern allows the treatment of various skin conditions by adjusting the intensity of light, and delay between pulses. The need for skin cooling and damage to skin treatment areas is eliminated by the quasi-logarithmic pulse spacing in conjunction with optimum length and characteristic shape of the individual pulses of light.

  • Patent number: 7022117
    Abstract: An aperture card is provided for insertion into a laser refractive ablation system for use in laser ablating the cornea. The aperture card is designed for single surgical use for surgical precautionary considerations and to achieve the highest quality ablations, in addition to reproducibility. The aperture card is loaded into the laser refractive ablation system in a path between the laser system and the eye. The aperture card is precisely located by positioning means and ablative lasing action is inhibited if the card is not positioned within tolerance. Alternatively, the laser system can determine the position of the aperture card and adjust a computed ablation profile or otherwise adjust the optical system to adapt for any misalignment of the apertures in the aperture card. The card contains a “soft spot” aperture capable of shaping a spatial intensity distribution with a unique profile.

  • Patent number: 7008415
    Abstract: Scanning spot locations are generated for ablating tissue using a scanning laser beam over a treatment region by taking a target function representing a desired lens profile of ablation with a basis function representing a treatment profile produced by overlapping scanning spots in a particular treatment pattern. In some embodiments, the basis function is a two-dimensional function representing a two-dimensional section of a three-dimensional treatment profile, which has symmetry with respect to the two-dimensional section extending along the treatment pattern. For example, the treatment pattern is generally straight for myopic and hyperopic cylinders, and is generally circular for myopia and hyperopia. The fit produces ablation depths for discrete scanning spots, which are used to calculate the number of pulses at each reference position along the two-dimensional section. The pulses are distributed along the treatment pattern to produce the desired overlapping effect.

  • Patent number: 7004935
    Abstract: The invention provides near-term customized ablation capabilities for treatment of corneal irregularities by ablating laterally offset refractive therapy profiles. These treatment profiles may, when centered on the eye, be suitable for treatment of standard refractive errors such as myopia, hyperopia, and cylindrical astigmatism. By selectively offsetting one or more of these ablation profiles at selected points across the corneal surface, the laser system can reduce refractive errors resulting from corneal irregularities such as irregular astigmatism, corneal steepening in one quadrant, asymmetrical astigmatism, irregularities inadvertently produced by a prior refractive treatment (such as radial keratotomy incisions, a decentered ablation, or the like), granular dystrophy, diffuse, asymmetric warpage as a result of post-corneal transplants, bilateral keratoconus, penetrating keratoplasty, or the like.

  • Patent number: 7001373
    Abstract: A laser surgery system having a computer control system coupled to a laser subsystem and a patient seat. The control system is coupled to the laser through a laser alignment system. The control system can be coupled to the patient seat through a patient alignment system. The control system sends a nominal position signal to move the patient seat, laser subsystem, or both so that the patient's first eye is moved into substantial alignment with the laser beam axis. The control system can send a second nominal signal to move the patient's second eye into substantial alignment with the laser beam axis. The control system can optionally comprise both an operator display and an assistant display. The assistant display provides real-time information to an assistant positioned at an assistant station adjacent the patient seat. The control system can be programmed to display edit fields with different colors to provide an obvious indication of the refractive information of the eye.

The instruments have end effectors that can be manipulated to hold and suture tissue. The robotic arms are coupled to a pair of master handles by a controller. The handles can be moved by the surgeon to produce a corresponding movement of the end effectors. The movement of the handles is scaled so that the end effectors have a corresponding movement that is different, typically smaller, than the movement performed by the hands of the surgeon. The scale factor is adjustable so that the surgeon can control the resolution of the end effector movement. The scale factor of the end effector can be set to zero to prevent movement of the end effector. An input button may also be provided so that the end effector only moves when the input button is depressed by the surgeon.
