Having Means To Temporarily Stabilize Haptic Patents (Class 623/6.45)
  • Patent number: 10925721
    Abstract: An optical implantable member (102) is provided. The optical implantable member (102) includes an optic (104). The optic (104) includes an anterior surface (108) and a posterior surface (110), an optical centre (112) and a peripheral edge (116). The optical implantable member (102) is configured to be placed within a capsular bag of the eye. The optic (104) of the optical implantable member (102) includes a barrier (202). The barrier (202) is formed by a protrusion (202) on the posterior surface (110) of the optic (104). The protrusion (202) is concentric to an optical axis (114) of the optic (104). An outer wall (204 or 208) of the protrusion (202) is between the peripheral edge (116) and the optical centre (112). The barrier (202) restricts epithelial cells from migrating towards a central region of the capsular bag.

  • Patent number: 10548716
    Abstract: A system and method for inserting an intraocular lens in a patient's eye includes a light source for generating a light beam, a scanner for deflecting the light beam to form an enclosed treatment pattern that includes a registration feature, and a delivery system for delivering the enclosed treatment pattern to target tissue in the patient's eye to form an enclosed incision therein having the registration feature. An intraocular lens is placed within the enclosed incision, wherein the intraocular lens has a registration feature that engages with the registration feature of the enclosed incision. Alternately, the scanner can make a separate registration incision for a post that is connected to the intraocular lens via a strut member.

  • Patent number: 8764823
    Abstract: A plate haptic for an accommodating intraocular lens. The plate haptic has a haptic body that is substantially rigid in a longitudinal direction and substantially flexible in a transverse direction. A chassis is integral to the haptic body. The chassis causes the haptic body to be substantially more rigid in a longitudinal direction than in a transverse direction.

  • Patent number: 8500806
    Abstract: 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.

  • Patent number: 7601169
    Abstract: An intraocular lens (IOL) system includes an optic, a pair of haptics located on sides of the optic, and hinge portions at each of the optic haptic junctions. The hinge portions have stressed and non-stressed configurations. One or more restraining elements are provided to maintain the stressed state configuration of the hinge portion during implantation and during a post-operative period during which the capsular bag of the eye heals about the lens. The restraining elements are thereafter removable, preferably via a non-surgically invasive manner, e.g., via dissolution or laser light. Removal of the restraining elements allows anteriorization of the optic as the lens assumes a non-stressed configuration during accommodation. The ciliary body and lens may then interact in a manner substantially similar to the physiological interaction between the ciliary body and a healthy natural crystalline lens.

  • Publication number: 20030171808
    Abstract: An intraocular lens (IOL) system includes a flexible lens having a skirt, and a restraining element. The restraining element is provided about the skirt and maintains the flexible lens in a stressed, non-accommodating configuration. At implantation, the ciliary body muscle is pharmacologically induced into a relaxed state, a capsulorrhexis is performed on the lens capsule, and the natural lens is removed from the capsule and replaced with the lens of the invention. The ciliary body is maintained in the relaxed state for several weeks until the capsule heals and shrinks about the lens. The restraining element is preferably designed to be removed in a non-surgically invasive manner, e.g., via dissolution or laser light, after capsule healing has occurred. The ciliary body and lens may then interact in a manner substantially similar to the physiological interaction between the ciliary body and a healthy natural crystalline lens.

  • Patent number: 6428572
    Abstract: It is an intraocular ring of open ring shape when inserting, so that it can be inserted from a small incision, and after being inserted into the capsule, by engaging the engaging mechanisms having mutually complementary male and female structures provided at ends of the intraocular ring, the intraocular ring having a nearly same compressive load as in closed ring is presented. Being made of an elastic material, it is an intraocular ring composed to contact with the entire inner circumference of the equatorial area in the capsule when inserted into the lenticular capsule, and engaging mechanisms are disposed at both ends in a partially cut-off state of the intraocular ring, and by engagement of the engaging mechanisms, a continuous ring shape without cut section is formed.

  • Patent number: 6395028
    Abstract: An anterior chamber phakic lens made from an elastomeric, foldable, highly biocompatible material. The lens has a generally circular optic and integrally formed plate-style haptics, the haptics containing an opening into which project a pair of pincer arms. The pincer arms are sized and shaped so as to pull away from each other when the lens is folded, and are draw back toward each other when the folded lens is released and allowed to return to its unfolded state. Such movement allows the pincers to gather a small section of the iris so as to hold the lens in place.
