摘要： Methods and devices for altering the power of a lens, such as an intraocular lens, are disclosed. In one method, the lens comprises a single polymer matrix containing crosslinkable pendant groups, wherein the polymer matrix increases in volume when crosslinked. The lens does not contain free monomer. Upon exposure to ultraviolet radiation, crosslinking causes the exposed portion of the lens to increase in volume, causing an increase in the refractive index. In another method, the lens comprises a polymer matrix containing photobleachable chromophores. Upon exposure to ultraviolet radiation, photobleaching causes a decrease in refractive index in the exposed portion without any change in lens thickness. These methods avoid the need to wait for diffusion to occur to change the lens shape and avoid the need for a second exposure to radiation to lock in the changes to the lens.
摘要翻译：公开了用于改变诸如人工晶状体的透镜的功率的方法和装置。在一种方法中，透镜包含含有可交联侧基的单一聚合物基质，其中当交联时聚合物基体的体积增加。镜头不含有游离单体。当暴露于紫外线辐射时，交联使得透镜的暴露部分体积增加，导致折射率增加。在另一种方法中，透镜包含含有可光漂白的发色团的聚合物基质。在紫外线照射下，光漂白导致曝光部分的折射率降低，透镜厚度没有变化。这些方法避免了等待发生扩散以改变透镜形状的需要，并且避免了第二次暴露于辐射以锁定透镜变化的需要。

摘要： Apparatus and methods for measuring a dynamic deformation characteristic of a deformable target surface during a deformation interval. The measurement principles may be applied to a large variety of organic and inorganic materials having a surface that can be deformed by an applied non-contact force. The surface may be light diffusing and non-transparent or non-diffusing and transparent. A device for measuring a dynamic deformation characteristic of an in-vivo cornea during a deformation interval includes a corneal topographer and an air puff generator that are operationally integrated. Use of the inventive device enables a method for making a measurement of a deformation characteristic of the in-vivo cornea during a deformation interval, further allowing a determination of spatially-resolved in-vivo corneal biomechanical and biodynamic properties such as corneal elasticity and corneal viscosity.

摘要： A method and apparatus related to enhancing corneal accommodation to address the effect of presbyopia. Corneal/scleral topology measurements in accommodation and non-accommodating states are indicative of a presbyopic subject’s nominal corneal accommodative power. A desired accommodative power intended to improve on the effect of presbyopia can be determined, suggesting a selective biomechanical intervention in the corneal structure outside of the optical zone to create flexure regions. These flexure regions would allow enhanced corneal accommodation upon presentation of an accommodating stimulus. Intervention could be in the form of, for example, corneal surface ablation, intrastromal ablation, conductive kerastoplasty (CK), laser thermal kerastoplasty (LTK), and corneal and/or scleral implants. An improved topology measuring apparatus having an improved field of view and other attributes is disclosed.

摘要： A system and a method for non-invasively ultrasonically measuring biomechanical properties of ocular tissue in vivo is presented. The method comprises positioning an ultrasonic transducer proximally to the ocular tissue. Reflections of the ocular tissue can be ultrasonically obtained using the ultrasonic transducer. The ultrasonic reflections can be converted into reflection spectra. Biomechanical properties of the ocular tissue, such as, for example, thickness, corneal stiffness, density, and longitudinal modulus, can be determined based on the reflection spectra. A wave propagation model can be developed to simulate ultrasound propagation of ocular tissue in vivo. The ultrasonic non-destructive evaluation method and system for the non-invasive measuring of reflection spectra and determining biomechanical properties of ocular tissue in vivo can provide information for ocular disease management and therapeutic and refractive procedures.

摘要： Embodiments of the invention are generally directed to apparatus and methods for measuring a deformation characteristic of a deformable target surface. The measurement principles of the invention may be applied to a large variety of organic (e.g., human, animal or plant tissue) and inorganic materials having a surface that can be deformed by an applied non-contact force. The surface may be light diffusing and non-transparent or non-diffusing and transparent. An illustrative embodiment of the invention is directed to a device for measuring a deformation characteristic of a cornea. The device comprises a corneal topographer and a non-contact tonometer that is operationally integrated with the corneal topographer. In an aspect, the corneal topographer is a rasterstereography-based topographer. Use of the inventive device enables a method for measuring a deformation characteristic of the cornea. In addition to the measurable deformation characteristics listed above, dioptric power, intraocular pressure, corneal hysteresis, corneal elasticity, corneal viscosity and various known corneal topography characteristics can be measured.
