Abstract: A haptic supporting an intraocular lens (IOL) in the eye permits radial tension from ciliary muscle relaxation rather than contraction to alter the lens power. The IOL is supported by the overlying tissue in the eye such as iris root, sclera and ciliary process, so that anterior and posterior forces on IOL are balanced, and buckling or displacement of lens in the eye or haptic is reduced or prevented. The haptic is of a thickness so as to increase stiffness and to reduce or prevent IOL buckling or displacement.

Abstract: An accommodating (re-focusable) lens system a body of which includes, upon being assembled, first and second individual lenslets having first and second optical portions sequentially disposed along an optical axis. Change in optical-power accommodation of the system is achieved by changing an applanated area of contact between the lenslets in response to force applied to the lenslets and transformed into an axial force. In specific case, the first and second lenslets form an intraocular lens (IOL) and have respective haptic portions, interlocked as a result of rotating of one lenslet with respect to another such as to bring first and second lenslets in contact at an axial point. The applanated area of contact is changed, then, in response to a radially-directed force caused by a change of distance between the interlocked ends of the haptics and transferred to die optical portions through the interlocked haptics.

Abstract: An intraocular lens (IOL) having a posterior prolate aspheric surface structured to bend or flex in response to force applied to such surface due to flexing of ciliary body muscle. The flexible and bendable haptic portions of the IOL, integrated with the central optical portion along its perimeter, as sized to have the distal sides of the haptic portions installed in the capsular membrane of a natural lens of an eye or in a space between the root of the iris and ciliary muscle. The optical power of the IOL is gradually modifiable due to change of curvature of the posterior prolate aspheric surface within the eye.

When installed in a natural lens capsule after the cataract extraction, the optical power of the IOL is gradually modifiable due to a change of curvature of the capsule caused by operation of a ciliary muscle.

Abstract: An accommodating (re-focusable) intraocular lens (IOL), a body of which includes two optical portions sequentially disposed, in optical contact with one another, along an optical axis and separated by interior surface the curvature of which is changing in response to pressure applied to posterior surface of IOL. The two optical portions may be formed with fluids having different refractive indices and housed in flexible cells that share an interior wall having such interior surface. The wall bends or flexes in response to force, caused by flexing of ciliary body muscle when IOL is installed in eye's capsule's membrane and passed onto the body of IOL via bendable haptics integrated with the optical portion(s) along a perimeter. The optical power of the IOL is gradually modifiable in part due to change of curvature of the interior surface.

Abstract: Ophthalmological device including an applanation tonometer tip having a bi-curved cornea-contacting surface and method of using such device for measurement of intraocular pressure. The cornea-contacting surface includes a first rotationally symmetric portion a curvature of which is substantially adapted to that of a typical cornea and a second rotationally symmetric portion that is peripheral to and adjoining the first portion. In operation, the applanation of the cornea in an area corresponding to the first portion of the cornea-contacting surface is substantially negligible.
