Accommodating intraocular lens

Номер: US20120078364A1
Автор: Donald C. Stenger
Принадлежит: Individual

An Accommodating Intraocular Lens (AIOL) is disclosed herein, that is comprised of a flexible optic and a flexible haptic rim that conforms to the human eye capsule. The spherical or custom shape of the optic is engineered to be maintained during accommodation through the mechanical/optic design of the implant and the interaction between the implant and the naturally occurring position and actuating forces applied through ciliary muscles/zonules/and capsule as the brain senses the need to increase the diopter change or magnification when an object of fixation approaches the eye. The axial relocation or position of the AIOL may also be further adjusted anatomically to further improve the affect needed to achieve improved accommodation. Optionally, the Accommodating Intraocular Lens (AIOL) is foldable or injectable for delivery of the lens into the eye.

Pre-stressed haptic for accommodating intraocular lens

Номер: US20130030525A1
Автор: Daniel G. Brady, Edward P. Geraghty, Randall L. Woods, Timothy R. Bumbalough
Принадлежит: Abbott Medical Optics Inc

An intraocular lens is disclosed, with an optic that changes shape in response to a deforming force exerted by the zonules of the eye. A haptic supports the optic around its equator and couples the optic to the capsular bag of the eye. The haptic may be pre-stressed before the optic is placed within it. After such placement, the pre-stress may be relieved, and the haptic may produce stress in the optic. The pre-stress may produce a radial tension or a radial compression in the optic. Alternatively, once the optic is placed within the haptic, both may undergo a process that changes the size and/or shape of one with respect to the other, causing a stress within the optic. This process may produce a radial tension or a radial compression in the optic. The haptic may include an annular ring having outer and inner diameters that may depend on the stiffness of the haptic.

Accommodating Intraocular Lens

Номер: US20130197635A1
Автор: Andrew F. Phillips
Принадлежит: Individual

An intraocular lens has a polymeric optic defined by a harder posterior layer and a softer anterior layer. Haptics having a fulcrum attached to the posterior layer and a resistance arm attached to the anterior layer are provided. A bias is provided to the haptic to rotate the haptics about the fulcrum and cause the resistance arm to deform the softer anterior layer about the harder posterior layer to increase the optical power of the lens. As the haptic rotates, it axially displaces the optic anteriorly to additionally increase the optical power. The optical power is adjustable in response to stresses induced by the eye. The haptics are subject to a pre-bias that urges the haptics to rotate or bend about the fulcrum. Temporary restraints are provided to the haptics to retain a stressed shape of the lens against the bias during a post-implantation healing period.

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 the optical portions through the interlocked haptics.

A method of altering a refractive property of a crosslinked acrylic polymer material by irradiating the material with a high energy pulsed laser beam to change its refractive index. The method is used to alter the refractive property, and hence the optical power, of an implantable intraocular lens after implantation in the patient's eye. In some examples, the wavelength of the laser beam is in the far red and near IR range and the light is absorbed by the crosslinked acrylic polymer via two-photon absorption at high laser pulse energy. The method also includes designing laser beam scan patterns that compensate for effects of multiphone absorption such as a shift in the depth of the laser pulse absorption location, and compensate for effects caused by high laser pulse energy such as thermal lensing. The method can be used to form a Fresnel lens in the optical zone. 14.-. (canceled)5. A method of altering a refractive property of an implantable intraocular lens having an optic body including an optical zone and a peripheral zone surrounding the optical zone , comprising:implanting the intraocular lens in a patient's eye;generating a light beam using a light source and a light delivery optical system, the light beam having a wavelength of 400 to 450 nm; andwhile the intraocular lens is in the patient's eye, irradiating the optical zone of the intraocular lens with the light beam,wherein the optical zone comprises a crosslinked acrylic polymer material configured to change its refractive index upon irradiation by the light beam, thereby altering a refractive property of the intraocular lens.6.

Принадлежит:

A system/method allowing intraocular lens (IOL) fabrication using a femtosecond laser is disclosed. The system and method generate a stream of pulses at a rate of at least 1 million pulses per second and a pulse length of 300 femtoseconds or less to sculpt a polymeric material blank (PMB) to form an IOL. The high repetition rate and short pulse length combine to permit IOL fabrication in less than 10 minutes. During this fabrication procedure a lens may be formed within the IOL by incorporating a refractive index shaping (RIS) structure within the IOL. Additionally, IOL haptics may be formed during this IOL formation process. This combination of physical feature generation and RIS structure generation permits per-patient customization of the IOL as it relates to sphere, cylinder, asphericity, multifocality, and/or higher optical aberrations (HOAs). 1.
