Abstract
A two part IOL with a generally “L” or “S” shape but featuring straight or curved “V”-shaped structures which can be inserted through a very small opening by flexing the arms of the “V”-shaped structures up to or over each other is described. This IOL may be used in the anterior or posterior chamber of the eye for phakic or aphakic lenses. After insertion of the haptic into the eye, any type of lens may be attached, especially by use of cleats. The haptic is a high modulus skeletal frame and the lens is preferably formed of a lower modulus material and is attachable to cleats on the frame.
Claims219
A multi-part intraocular lens (IOL) comprising:
- an optic;
- a haptic comprising:
- at least one “V”-shaped element having a pair of legs and a square or rounded corner;
- and
- at least two contact points for the eye each located on one of said legs or one of said corners;
- and
- an attachment for the optic onto the haptic.
A multi-part intraocular lens, comprising:
- a haptic with at least two “V” shaped elements;
- a separate optic;
- and
- an attachment for said optic which permits said optic to be attached to said haptic within the eye.
A haptic for an intraocular lens, comprising:
- a first “V” shaped portion, having a maximum interior angle less than 90° and two arms;
- and
- a second “V” shaped portion, having a maximum interior angle less than 90° and two arms, one of said arms joined to said first “V” shaped portion at said interior angle of said first “V” shape.
A method of inserting a haptic into a patient's eye, comprising:
- threading said haptic through an incision smaller than 2.0 mm into said eye, by bending the arms of two “V” shaped structures onto each other as they pass through said incision.
A method for introducing an intraocular lens haptic having first and second “V”-shaped elements into a very small incision in an eye, comprising:
- flexing each arm of said first “V”-shaped element of said haptic next to or over each other and inserting said first “V”-shaped element into the eye;
- and
- flexing each arm of said second “V”-shaped element of said haptic next to or over each other and inserting said second “V”-shaped element into the eye.
A method for introducing an intraocular lens haptic having first and second “V”-shaped elements into a very small incision in an eye, comprising:
- flexing each arm of said first “V”-shaped element of said haptic next to or over each other and inserting said first “V”-shaped element into the eye;
- and
- manipulating without bending said second “V”-shaped element into the eye.
A haptic for supporting an intraocular lens in an eye, and for insertion into said eye through a small incision, comprising:
- a pair of arms, connected at one end to form a “V”-shape, at least one of said arms sufficiently flexible to permit said small incision to squeeze said pair of arms toward one another as said haptic is inserted through said small incision.
A haptic for supporting an intraocular lens in an eye, and for insertion into said eye through a small incision, comprising:
- a connected pair of V-shaped elements, aligned in the same direction along the length of said haptic.
A haptic for supporting an intraocular lens in an eye, and for insertion into said eye through a small incision, comprising:
- a connected pair of straight or rounded V-shaped elements, aligned in opposite directions along the length of said haptic.
