LIGHT-ADJUSTABLE MULTI-ELEMENT OPHTHALMIC LENS
A multi-element IOL, comprising an anterior lens element comprising a light-adjustable material responsive to light of a first wavelength, and a posterior lens element comprising a light blocker capable of blocking light of the first wavelength, and a method of inserting the multi-element IOL.
1 . A multi-element ophthalmic lens (OL), comprising:
an anterior lens element comprising a light-adjustable material responsive to light of a first wavelength; and
a posterior lens element comprising a light blocker capable of blocking light of the first wavelength.
2 . The OL of claim 1 , wherein the OL is an accommodative IOL.
3 . The OL of claim 1 , wherein the anterior lens element and the posterior lens element are mechanically connected together.
4 . The OL of claim 1 , wherein the light-adjustable material is responsive to light having a wavelength in the range 300 nm to 450 nm.
5 . The OL of claim 1 , wherein anterior lens element is adapted to be located in an anterior chamber of an eye and the posterior lens element is adapted to be located in a posterior chamber of the eye.
6 . A method of implanting a multi-element OL, comprising:
implanting a first lens element comprising a light-adjustable material responsive to light of a first wavelength; and
implanting a second lens element posterior to the first lens element, the second lens element comprising a light blocker capable of blocking light of the first wavelength.
7 . The method of claim 6 , wherein the first lens element and the second lens element are mechanically coupled together.
8 . The method of claim 6 , further comprising projecting light of the first wavelength onto the second lens element by projecting the light through the first lens element.
9 . The method of claim 6 , wherein the step of implanting the first lens element comprises implanting the first lens element in an anterior portion of the eye.
10 . The method of claim 7 , wherein the step of implanting the second lens element comprises implanting the first lens element in a posterior chamber of the eye.
11 . The method of claim 6 , wherein the step of implanting the first lens element comprises implanting the first lens element in a posterior chamber of the eye and the step of implanting the second lens element comprises implanting the second lens element in the posterior chamber of the eye.
12 . The method of claim 6 , wherein the step of implanting the first lens element comprises implanting the first lens element in an anterior portion of the eye and the step of implanting the second lens element comprises implanting the second lens element in the anterior portion of the eye.
13 . The method of claim 6 , wherein the step of implanting the second lens element is performed prior to the step of implanting the first lens element.
