    摘要： Embodiments apply light energy in medical treatments. To enhance or control the effect of the light energy, embodiments apply the light energy after tissue has been treated, e.g., with a photosensitizing agent. For example, embodiments may treat target tissue with riboflavin before exposure to ultraviolet light. For example, a system for cataract surgery includes a removal system configured to remove a first lens from an eye, wherein a capsular bag remains in the eye after removal of the first lens. The system includes an application system configured to treat lenticular epithelial cells in the capsular bag with the photosensitizing agent. The system includes a delivery system with a light source and an optical device. The optical device delivers light to the treated lenticular epithelial cells. Energy from the light destroys the lenticular epithelial cells in the capsular bag to reduce the growth of epithelial cells that cause posterior capsule opacification.

    摘要： In a system for stabilizing a pattern of structural changes in corneal fibrils, an eye treatment system causes corneal fibrils of a cornea of an eye to transition from a first structure to a second structure. An application device applies a cross-linking element to the corneal fibrils. An activating device applies an initiating element to the corneal fibrils and activates the cross-linking element. The cross-linking element causes cross-linking in the corneal fibrils to preserve the second structure of the corneal fibrils. Another application device may apply a cross-linking breaker to the corneal fibrils. The cross-linking breaker halts or reverses at least partially the cross-linking in the corneal fibrils. Another activating device applies an initiating element to the corneal fibrils and activates the cross-linking breaker. Advantageously, the cross-linking breaker provides greater control over the amount and progress of cross-linking that occurs in the corneal fibrils.

    摘要： Embodiments apply a cross-linking agent to a region of corneal tissue. The cross-linking agent improves the ability of the corneal tissue to resist undesired structural changes. For example, the cross-linking agent may be Riboflavin or Rose Bengal, and the initiating element may be photoactivating light, such as ultraviolet (UV) light. In these embodiments, the photoactivating light initiates cross-linking activity by irradiating the applied cross-linking agent to release reactive oxygen radicals in the corneal tissue. The cross-linking agent acts as a sensitizer to convert O2 into singlet oxygen which causes cross-linking within the corneal tissue. The rate of cross-linking in the cornea is related to the concentration of O2 present when the cross-linking agent is irradiated with photoactivating light. Accordingly, the embodiments control the concentration of O2 during irradiation to increase or decrease the rate of cross-linking and achieve a desired amount of cross-linking.

    摘要： A multimodal biometric identification system captures and processes images of both the iris and the retina for biometric identification. Another multimodal ocular system captures and processes images of the iris and/or the from both eyes of a subject. Biometrics based on data provided by these systems are more accurate and robust than using biometrics that include data from only the iris or only the retina from a single eye. An exemplary embodiment emits photons to the iris and the retina of both eyes, an iris image sensor that captures an image of the iris when the iris reflects the emitted light, a retina image sensor that captures an image of the retina when the retina reflects the emitted light, and a controller that controls the iris and the retina illumination sources, where the captured image of the iris and the captured image of the retina contain biometric data.

    摘要： Systems and methods stabilize corneal tissue after treatment of the corneal tissue. For example, thermokeratoplasty may be applied to the corneal tissue to address disorders associated with abnormal shaping of the cornea. To stabilize the desired structural changes caused by the treatment, embodiments apply ophthalmic formulations that help to inhibit wound healing. Wound healing may occur in response to the application of the treatment and may produce further structural changes that mitigate or alter the desired effects of the treatment.
