The eyesight improving instrument to guide medicine liquid to human eye to treat eye diseases includes a pulse generator and positive and negative electrode plates. The pulse generator includes a vibration pulse generating circuit, a vibration pulse amplifying and outputting circuit, and a timing control circuit. The vibration pulse generating circuit includes two pulse vibrators, each of which comprises a voltage compressor and resistors, capacitors and other electronic elements; and one third voltage comparator, which accepts two square wave signals of frequency of 3500-4500 Hz and 35-100 Hz separately from the two pulse vibrators to generate harmonics of 35-4500 Hz frequency. The harmonics is then amplified in the vibration pulse amplifying and outputting circuit to 100-1000 mV amplitude, and the amplified harmonics are coupled to the electrode plates. The timing control circuit controls the operation time of the vibration pulse generating circuit.

Meanwhile, the device is a small wearable device in the shape similar to that of glasses, people can use the device to know the vision condition anytime and anywhere and receive treatment in the daily life, therefore, the use is convenient, and the device is particular suitable for use by families and individuals.

An ophthalmic surgical device is disclosed that combines laser energy for treatment of vision or ocular defect and illumination energy for visualization of a treatment site during surgery in a single common waveguide fiber, thereby enabling reduction of a diameter of a probe or canula of the device, whereby a smaller incision may be utilized to reduce trauma to the eye. The device may further include additional features, such as a conduit for supply of material or removal of material from the treatment site.

Method and system for treating of visual impairment associated with misalignment between eyes of a patient is described. The invention allows to obtain electronically of an image of an object at which one eye of the patient is staring, calculating angular deviation between staring direction of this eye and the second eye and displaying before the second eye the image after it has been electronically processed so as to correct the angular deviation and to obtain the image, which would be perceptible by the brain as a single three dimensional stereoscopic image.

Disclosed is a computer-implemented method for correcting refractive errors in a living eye using a laser vision correction system that involves first calculating an amount of sphere based on preoperative manifest refraction and higher order aberrations data associated with the eye, and then correcting for the calculated amount of sphere by ablating at least a portion of the eye. The preoperative manifest refraction may include preoperative manifest sphere, preoperative spherical equivalent, regular astigmatism, and oblique astigmatism, and the preoperative higher-order aberrations may include 4th-order spherical and 3rd root mean square. Other factors may also be used to adjust the calculated amount of sphere. A device readable medium for storing the calculation and instructions for operating a laser vision correction system for practicing the method is also disclosed, as is a method of treating refractive errors.
