Eye therapy system

Номер: US0009498642B2
Принадлежит: Avedro, Inc., AVEDRO INC

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.

Methods for enhancing accommodation of a natural lens of an eye

Номер: AU2010300664A1
Принадлежит:

The accommodative properties of the natural lens of an eye, which tend to degrade with age, can be enhanced, restored, or otherwise improved using the in situ treatment techniques and methodologies provided here. One exemplary method of enhancing accommodative properties of the natural lens of an eye involves an initial step of specifying treatment areas of the natural lens. These treatment areas correspond to regions of the capsular bag or regions of the crystalline lens. The method continues by increasing stiffness of the treatment areas while all or portions of the natural lens remains in situ. This results in stiffened areas of the natural lens that enhance transfer of ciliary muscle forces to a center region of the crystalline lens.

Heat is generated in corneal fibrils in a cornea of an eye according to a selected pattern. The heat causes the corneal fibrils corresponding to the selected pattern to transition from a first structure to a second structure. The second structure provides a desired reshaping of the cornea. A cross-linking agent is then activated in the region of corneal fibrils according to the selected pattern. The cross-linking agent prevents the corneal fibrils from changing from the second structure. Thus, embodiments stabilize corneal tissue and improve its biomechanical strength after desired structural changes have been achieved in the corneal tissue. Accordingly, the embodiments help to preserve the desired reshaping of the cornea.

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 O 2 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 O 2 present when the cross-linking agent is irradiated with photoactivating light. Accordingly, the embodiments control the concentration of O 2 during irradiation to increase or decrease the rate of cross-linking and achieve a desired amount of cross-linking.

Heat is generated in corneal fibrils in a cornea of an eye according to a selected pattern. The heat causes the corneal fibrils corresponding to the selected pattern to transition from a first structure to a second structure. The second structure provides a desired reshaping of the cornea. A cross-linking agent is then activated in the region of corneal fibrils according to the selected pattern. The cross-linking agent prevents the corneal fibrils from changing from the second structure. Thus, embodiments stabilize corneal tissue and improve its biomechanical strength after desired structural changes have been achieved in the corneal tissue. Accordingly, the embodiments help to preserve the desired reshaping of the cornea.

Because the change in ultrasonic response is correlated with the degree of crosslinking achieved, a desired degree of crosslinking can be achieved by terminating the irradiation when the change reaches a threshold. The change in ultrasonic response can be determined by taking a baseline measurement before irradiation and additional measurements during irradiation using the same ultrasonic transducer (). The transducers may be carried on a device () resembling a contact lens which overlies the eye and which transmits the light used in the irradiation step to the eye. 1. A device for applying irradiation and ultrasound to an eye of a subject comprising:(a) a housing having an inwardly-facing surface adapted to rest on an anterior surface of the eye;(b) an optical diffuser mounted to the housing, the diffuser having inner and outer surfaces facing inwardly and outwardly; and(c) a ultrasonic transducer mounted to the housing and disposed outward of the diffuser so that the diffuser is disposed between the transducer and the eye when the housing rests on the anterior surface of the eye.2.

DEUTERON THERAPY

Disclosed is a method of utilizing deuterons (nuclear particles consisting of a proton and a neutron) for charged particle radiotherapy. Compared with proton therapy, at their maximum treatment depth of 66 mm, 125 MeV deuterons possess 82-85% less beam straggling than protons. This difference enables better protection of radiosensitive critical tissues that may be in contact with a tumor. Alternatively, it enables higher doses to be delivered to the tumor, resulting in better tumor control. The implementation of deuteron therapy interchangeably alongside proton therapy requires minor modifications at modest cost to many existing proton therapy systems and provides a clinically useful hybrid particle therapy facility. A free-standing deuteron therapy facility that employs only deuterons is also described. 1.
