A method and system are provided for sensing eye movement, such as saccadic eye movement, in a non-intrusive fashion. An optical delivery arrangement converts a laser beam pulse into a plurality of light spots. The light spots are focused such that they are incident on a corresponding plurality of positions located on a boundary whose movement is coincident with that of eye movement. The boundary can be defined by two visually adjoining surfaces having different coefficients of reflection. Energy is reflected from each of the positions located on the boundary receiving the light spots. An optical receiving arrangement detects the reflected energy from each of the positions. Changes in reflected energy at one or more of the positions is indicative of eye movement.

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 sectional patterns results in the shaped structural weakening of the lens. There is also provided a method and system for determining adjustments to refractive errors in the lens of an eye relating to the treatment of presbyopia. The change to refractive error can be a predicted error or an actual error that has been determined.
