Abstract
Methods for the creation of microspheres treat the clear, intact crystalline lens of the eye with energy pulses, such as from lasers, for the purpose of correcting presbyopia, other refractive errors, and for the retardation and prevention of cataracts. Microsphere formation in non-contiguous patterns or in contiguous volumes works to change the flexure, mass, or shape of the crystalline lens in order to maintain or reestablish the focus of light passing through the ocular lens onto the macular area, and to maintain or reestablish fluid transport within the ocular lens.
Claims10
A method for increasing the flexibility of the ocular lens of the eye, comprising the steps of:
- a) selecting a location within the ocular lens of an eye;
- b) creating a microsphere at the selected location, wherein said microsphere comprises a gas-filled bubble of generally spherical shape;
- and
- c) repeating the steps of selecting and creating at a plurality of locations within the ocular lens so as to increase the flexibility of the lens
- wherein the microspheres created in step c) remain predominantly separate until after the last microsphere has been created.
