摘要： Wavefront measurements of eyes are often taken when the pupil is in a first configuration in an evaluation context. The results can be represented by a set of basis function coefficients. Prescriptive treatments are often applied in a treatment context, which is different from the evaluation context. Hence, the patient pupil can be in a different, second configuration, during treatment. Systems and methods are provided for determining a transformed set of basis function coefficients, based on a difference between the first and second configurations, which can be used to establish the vision treatment.

摘要： Presbyopia in a patient's eye is treated by inducing spherical aberration in the central section of the pupil, while the peripheral section of the pupil is treated in a manner other than the central section of the pupil. For example, the peripheral section of the pupil may remain untreated, or high-order aberration may be controlled, and/or a second area of spherical aberration may be provided with different focus power.

摘要： An eye contact device and assembly for stabilizing a human eye at a selected position in an external coordinate system is disclosed. The device includes an eye-contact member having an inner contact surface for contacting a front surface of an eye, and a vacuum port formed within the eye-contact member by which a negative pressure can be applied between the eye and the contact surface, to stabilize the position of the eye with respect to the device. The device, which is adapted to be biased against the patient's eye, to secure the device to the eye, may be pivotally coupled to a positioning arm, and may carry one or more beam-directing elements by which the position of the device in an external coordinate system can be determined.

摘要： A system for securing a patient eye at a known position in an external coordinate system is disclosed. The system includes a head support for supporting the patient's head, an eye-contact device including a concave contact surface adapted to be placed against the front surface of a patient's eye, and a port in fluid communication with the contact surface, by which a vacuum can be applied to the device to remove air between the eye and the contact surface, to stabilize the position of the eye with respect to the contact device, and a biasing mechanism operatively connected to the contact device for biasing the contact device against the eye with a force sufficient to the hold the contact device against the eye, when the eye is stabilized with respect to the device by removal of air between the eye and the device's contact surface.

摘要： A method of modifying a cornea of an eye to reduce refractive error, the cornea having a surface and a main optical axis, including the steps of aiming and firing a laser at the cornea of the eye. The laser first separates an internal portion of the cornea forming a first internal surface and a second internal surface, the first internal surface facing in a posterior direction of the cornea and the second internal surface facing in an anterior direction of the cornea, with the first and second internal surfaces forming an internal pocket therebetween. An incision is then made from the surface of the cornea to the internal pocket, and an ocular implant is introduced through the incision and into the internal pocket of the cornea.

摘要： Optically transparent, high water content, hydrogel polymeric materials and photoablatable inlays fabricated therefrom are described herein. The preferred hydrogel polymeric materials have a refractive index of 1.30 or above in the hydrated state and a water content of approximately 60 percent or greater by weight. The preferred hydrogel polymeric materials likewise show no signs of cracking or haze following clinical ablation.

摘要： Improved methods of spherical and astigmatic laser correction. By using an array of micro-charge coupled devices, a spatially-resolved refractive error map is generated which guides the treatment process. Improved astigmatic correction is provided by avoiding laser treatment of the unaffected cornea. Complex astigmatic corrections including lenticular astigmatism and mixed astigmatism are treated by first sphericizing the corneal surface before correcting the residual refractive error.

摘要： Evaluation of a laser used in ophthalmologic surgery. A test substrate is formed from a homogenous material of controlled water content that ablates at a rate approximately that of human corneal tissue. A first non-contact surface topographical analysis of the test substrate is performed prior to laser ablation. Laser ablation is performed on the test substrate. A second non-contact surface topographical analysis of the test substrate is performed. The second surface topographical analysis is compared with the first to evaluate the surgical laser. The analysis is used to calibrate the laser. The data also is used to enhance the predictive value of a self-educating neural network. The non-contact surface topographical analysis is performed by rasterstereography, videokeratography, laser holography, scanning laser ophthalmoscope, optical coherence tomography, and scanning white light interferometry.

摘要： A universally sized blank made of organic or synthetic material that can be placed on an exposed inner surface of a live cornea and ablated with a laser beam to be altered to a particular shape. The blank can be disk-shaped, annularly-shaped with a through opening, or any other suitable shape. A flap-like portion of the live cornea is removed to expose an inner surface of the cornea, and the blank is positioned on the exposed inner surface of the eye. A laser beam is directed onto a portion of the exposed inner surface (e.g., exposed at the opening in the blank), a portion of the blank, or both, based on the type of ametropic condition (i.e., myopia, hyperopia or astigmatism) of the eye needing correction, so that the laser beam ablates those portions of the inner surface and/or blank and thus reshapes the inner surface, the blank, or both. The flap-like portion of the cornea is repositioned over the remaining portion of the blank, so that a remaining portion of the blank and the inner surface influence the shape of the reattached flap-like portion of the cornea and thus modifies the curvature of the cornea.

摘要： Accurate, non-mechanical removal of the epithelium from essentially only the area of the cornea to be treated. In particular, an epithelium-ablative laser device irradiates the selected region of the epithelium with ablative laser energy, a spectroscopic system monitors the ablation and spectroscopically determines whether epithelium is being ablated, and a control system terminates the epithelium removal upon spectroscopic determination of a substantial absence of epithelium ablation.
