Systems, methods, and devices for promoting eyelash hair growth includes an energy transducer, positionable proximate the eyelid, configured to provide light energy to a user's eyelids at an output wavelength suitable for stimulating eyelash hair growth, and a scleral shield, positionable inside of the eyelid, to protect the eye from the light energy. The device may be powered by an internal power source, such as a rechargeable battery or disposable batteries, or by an external power source, such as a plug used in connection with an AC outlet. In use, the eyelid is positioned between the energy transducer and the scleral shield, and the light energy from the energy transducer is applied to the eyelash region of the eyelid to promote eyelash hair growth.

A system (20) includes a radiation source (48) and a controller (44), configured to display a live sequence of images of an eye (25) of a patient (22), while displaying the sequence of images, cause the radiation source to irradiate the eye with one or more aiming beams (84), which are visible in the images, subsequently to causing the radiation source to irradiate the eye with the aiming beams, receive a confirmation input from a user, and in response to receiving the confirmation input, treat the eye by causing the radiation source to irradiate respective target regions of the eye with a plurality of treatment beams. Other embodiments are also described.

A narrow angle illumination light source for an ophthalmic surgical laser system includes multiple light emitting diodes (LEDs), multiple corresponding ball lenses, multiple corresponding upper apertures located between the LEDs and the lenses (optional), and multiple corresponding lower apertures located below the lenses. The light passing through each upper aperture and corresponding lens forms a light cone having a defined divergence angle and cone axis angle; the light cone only illuminates the corneal and sclera of a docked eye without illuminating the patients nose and orbit. The lower apertures may have distinctive shapes to aid video focusing. The multiple LEDs are distributed uniformly in the circle, and may be divided into multiple independently controllable segments which allows directional illumination The LEDs also have controllable brightness to allow images of darker and brighter illuminations to be taken in short succession.

Methods for treatment of dry eye and other acute or chronic inflammatory processes are disclosed herein. One method includes administering a drug delivery implant to a patient in need thereof, the drug delivery implant comprising one or more Rock inhibitors and/or one or more Wnt inhibitors, the patient having a medical condition selected from the group consisting of dry eye, lichen planus, arthritis, psoriasis, plantar fasciitis, pars planitis, scleritis, keratitis, chronic meibomian gland inflammation, optic nerve neuritis, uveitis, papillitis, diabetic neural pain, diabetic retinopathy, a cataract, a side effect occurring after refractive surgery, a side effect occurring after corneal transplant, a side effect occurring after retinal detachment surgery, and combinations thereof. The administration of the drug delivery implant to the patient treats the medical condition, reduces the symptoms associated with the medical condition, enhances nerve regeneration, and/or alleviates the medical condition.

A probe as disclosed herein is capable of treating both the Schlemm's canal (SC) and the trabecular meshwork (TM), or both the pars plicata and the iris root site of the eye, with electromagnetic radiation (e.g., laser light) to improve aqueous humor outflow and thus decrease intraocular pressure (IOP). The laser probe can include a tip capable of being placed on an eye, such as on a corneal limbus or a scleral limbal area of the eye. The tip can include an optical waveguide angled to direct laser light through both the SC and TM, or both the pars plicata and the iris root site of the eye. The laser light can be continuous or pulsed, and can be configured to provide appropriate therapy to both the SC and TM, or to both the pars plicata and the iris root site. The laser probe can facilitate performing trans-scleral trabeculoplasty treatment, especially trans-scleral Schlemm trabeculoplasty, and performing iridoplasty treatment.

A device and method for cutting or ablating tissue in a human or veterinary patient includes an elongate probe having a distal end, a tissue cutting or ablating apparatus located adjacent within the distal end, and a tissue protector extending from the distal end. The protector generally has a first side and a second side and the tissue cutting or ablating apparatus is located adjacent to the first side thereof. The distal end is structured to be 0 into tissue or otherwise placed and positioned within the patient's body such that tissue adjacent to the first side of the protector is cut away or ablated by the tissue cutting or ablation apparatus while tissue that is adjacent to the second side of the protector is not substantially damaged by the tissue cutting or ablating apparatus.

An ophthalmic treatment system and method for performing therapy on target tissue in a patient's eye. A delivery system delivers treatment light to the patient's eye and a camera captures a live image of the patient's eye. Control electronics control the delivery system, register a pre-treatment image of the patient's eye to the camera's live image (where the pre-treatment image includes a treatment template that identifies target tissue within the patient's eye), and verify whether or not the delivery system is aligned to the target tissue defined by the treatment template. The control electronics control the delivery system to project the treatment light onto the patient's eye in response to both an activation of a trigger device and the verification that the delivery system is aligned to the target tissue, as well as adjust delivery system alignment to track eye movement.

A dual blade device and method useable for performing an ab interno procedure within a human eye to remove a strip of trabecular meshwork tissue.

Systems and methods for monitoring properties of the cornea and controlling the crosslinking treatment. The thickness of the cornea during crosslinking may be measured by using ultrasonic reflections to determine an anterior distance (D.sub.1′) between a reference location (37) on a device resting on the eye and an anterior surface (66) of the cornea and to determine a posterior distance (D.sub.3′) between a posterior surface (63) of the cornea and an element of the eye such as an anterior surface (72) of the lens of the eye. These distances are subtracted from a reference distance (D.sub.0) between the reference location and the element of the eye. The reference distance (D.sub.0) may be determined using ultrasonic reflections to determine the corresponding anterior and posterior distances and the thickness (D.sub.2) of the cornea prior to crosslinking. The speed of sound in the cornea during crosslinking may be derived using the thickness (D2′) and time of flight of ultrasound through the cornea. The position of the cornea relative to a reference location may be determined. In still other embodiments, location of a surface of demarcation (86) within the cornea formed as a result of crosslinking may be determined. Still other embodiments provide for determination of one or more resonant frequencies of the cornea, and for measurement of responses of the cornea to applied forces, such as displacement and rebound velocity. The properties of the cornea may be used as proxies for the extent of crosslinking, and a light source (48, 348) used to induce crosslinking may be controlled in response to such proxies.

Devices and approaches for activating cross-linking within corneal tissue to stabilize and strengthen the corneal tissue following an eye therapy treatment. A feedback system is provided to acquire measurements and pass feedback information to a controller. The feedback system may include an interferometer system, a corneal polarimetry system, or other configurations for monitoring cross-linking activity within the cornea. The controller is adapted to analyze the feedback information and adjust treatment to the eye based on the information. Aspects of the feedback system may also be used to monitor and diagnose features of the eye. Methods of activating cross-linking according to information provided by a feedback system in order to improve accuracy and safety of a cross-linking therapy are also provided.
