Method and apparatus for detecting and reducing motion blur caused by the movement between a camera and an object including calculation of first and second figures of merit associated with two substantially orthogonal directions and comparison of the figures of merit and adjustment of the magnitude of the amplitude of spatial frequencies of the image in response to the comparison.

A system and apparatus for increasing the amplitude of accommodation and / or changing the refractive power and / or enabling the removal of the clear or cataractous lens material of a natural crystalline lens is provided. Generally, the system comprises a laser, optics for delivering the laser beam and a control system for delivering the laser beam to the lens in a particular pattern. There is further provided apparatus for determining the shape and position of the lens with respect to the laser. There is yet further provided a method and system for delivering a laser beam in the lens of the eye in a predetermined shot pattern.

A system and method for increasing the amplitude of accommodation and / or changing the refractive power of lens material of a natural crystalline lens is provided. Generally, there is provided methods and systems for delivering a laser beam to a lens of an eye in a plurality of patterns results in the increased accommodative amplitude and / or refractive power of the lens. There is further provided a system and method of treating presbyopia by increasing both the flexibility of the human lens and the depth of field of the eye.

Presbyopia may be treated by implanting a scleral prosthesis within a plurality of elongated pockets formed in the tissue of the sclera of the eye. The implanted prosthesis exerts traction on the sclera in the region overlying the ciliary body which expands the sclera and the underlying ciliary body. This restores the effective working distance of the ciliary muscle and increases the amplitude of accommodation. A prosthesis of the present invention that contacts the sclera of an eyeball comprises a body having a first end and a second end. The body has (i) a planform for expanding the contacted sclera to increase the effective working distance of the ciliary muscle of the eyeball, and (ii) a structure that stabilizes the prosthesis within the surgically formed pocket within the sclera of the eyeball.

The invention relates to a human eye health state judging system. A graphic processing calculation module is utilized to calculate the diameter of the iris in a far point face image and the diameter of the iris in a near point face image, then calculate a sight distance of the single eye at the far point according to the diameter of the iris that the far point face image corresponds to and calculate a sight distance of the single eye at the near point according to the diameter of the iris that the near point face image corresponds to, and then calculate the diopter at the far point and the diopter at the near point according to the two sight distances. The difference between the two diopter values is the adjustment amplitude, and finally the eye health state of a consumer is judged according to the difference between the adjustment amplitude and the empirical value. According to the system, the presbyopia diopter can be measured by a user or an optical store, the influence of subjective factors of consumers in the traditional glasses preparation process is avoided, and the glasses preparation process is simplified. Each consumer can grasp the degree change clearly, so that the consumers can perform eye exercises according to suggestions in diet and life provided by software.

The present invention relates generally to a device and method for the treatment of, ocular hypertension, glaucoma, and increasing the amplitude of accommodation. In an illustrative embodiment, the device includes a self-expanding wire. Once the device is within the posterior chamber between the iris and anterior lens capsule, the wire expands to compress the ciliary muscle. When the device is in place the scleral spur is moved posteriorly resulting in traction on the trabecular meshwork, which causes a reduction in intraocular pressure for the treatment of patients with ocular hypertension and glaucoma. In addition, the compression of the ciliary muscle increases the force of contraction of the ciliary muscle, which increases the amplitude of accommodation in patients with deficient accommodative amplitude and presbyopia.
