Abstract: A treatment apparatus for operatively correcting myopia or hyperopia in an eye includes a laser device controlled by a control device and that separates the corneal tissue by applying a laser beam. The control device controls the laser device to emit the laser beam into the cornea such that a lenticule-shaped volume is isolated in the cornea. The control device, when controlling the laser device, predefines the lenticule-shaped volume such that the volume has a minimum thickness of between 5 and 50 ?m. For myopia correction, the minimum thickness occurs on the edge of the volume, and for hyperopia correction the minimum thickness occurs in the region of the visual axis.

Abstract: Embodiments for protecting low-pressure blood pressure sensors in high-pressure fluid flow applications by equalizing pressure on both sides of a pressure sensor's diaphragm during high pressure are disclosed. A sensor protection device may include a pressure sensor assembly, a housing, and a plunger assembly. During low pressure, fluid in the primary flow path can flow through the housing, transferring its pressure to a first side of the diaphragm; the plunger assembly can prevent fluid flow into a secondary flow path in the housing, transferring atmospheric pressure to a second side of the diaphragm. During high pressure, fluid can still flow through the primary flow path, and the plunger assembly may now allow fluid flow into the secondary flow path, transferring pressure from the same fluid to the second side of the diaphragm to equal pressure across the diaphragm. The plunger assembly may automatically transition between low- and high-pressure configurations.

Abstract: Embodiments of the invention provide hydrodissection and/or PCO prevention or reduction in a patient undergoing eye surgery. In one embodiment, the invention is a surgical device for cutting and excising a portion of tissue, for example in performing a lens capsulotomy. A capsulotomy tip is inserted into an eye through an incision in the surface of the eye. The capsulotomy tip includes a suction cup to provide suction to the lens capsule. Then suction is applied via the suction cup to secure the capsulotomy tip to the eye. In some embodiments, after the capsulotomy tip is secured to the lens capsule, a cutting element of the capsulotomy tip is used to cut a tissue of the eye. Fluid is pushed through the capsulotomy tip and the capsulotomy tip is removed from the eye. Moreover, disclosed is an intraocular lens (IOL) to be used in conjunction with the surgical device.

Abstract: In a laser cataract procedure that also corrects for astigmatism, an iris registration method compares an iris image of a patient's eye taken when the eye is not docked to a patient interface device with an iris image of the same eye that is docked to the patient interface, to calculate a rotation angle between the two images. The astigmatism axis of the eye is measured when the eye is not docked, and the measured axis is rotated by the calculated rotation angle to obtain a rotated astigmatism axis relative to the iris image of the docked eye. The laser cataract procedure is performed based on the rotated astigmatism axis. The rotation angle is calculated by optimizing a transformation that transforms the undocked iris image to match the docked iris image, where the transformation includes a dilation factor that accounts for different pupil dilation of the two iris images.
