Abstract
A method of providing an artificial lens inserted into the eye between the iris and the natural lens zone, there being eye ciliary muscles located peripherally of the zone, that includes providing the artificial lens to be compliant and to have anterior and posterior surfaces, and haptics extending away from the periphery of the artificial lens; and inserting the artificial lens to extend into position between the iris and the zone, and to cause the haptics to extend into adjacency to the ciliary muscles, and; allowing the haptics to adhere to the ciliary muscles; whereby subsequent movement of the ciliary muscles causes movement of the haptics transmitted to effect bodily movement of the lens in posterior and anterior directions to change the angularity of refraction of light passing through the lens toward the eye retina.
Claims31
The method of providing an artificial lens inserted into the eye between the iris and the natural lens zone, having existing lens there being eye ciliary muscles located peripherally of said zone, that includes
- a) providing said artificial lens to be compliant and to have anterior and posterior surfaces, and haptics extending away from the periphery of the artificial lens,
- b) and inserting said artificial lens to extend into position between the iris and said zone, and to cause said haptics to extend into adjacency to said ciliary muscles, and
- c) allowing said haptics to adhere to said ciliary muscles, so as to maintain a fluid gap between a medial portion of said artificial lens and said natural lens zone, and so as to maintain the artificial lens and haptics spaced from the iris,
- d) whereby subsequent movement of said ciliary muscles causes movement of said haptics transmitted to effect bodily movement of said artificial lens in posterior and anterior directions to change the angularity of refraction of light passing through said artificial lens toward the eye retina.
The method of improving eye vision, that includes:
- a) inserting a first artificial lens into the posterior zone of the eye having an existing lens and temporarily positioned for eye vision correction use, in conjunction with an existing lens at the eye capsule zone,
- b) thereafter removing said first artificial lens from the eye, and
- c) inserting a second and different artificial lens into the posterior zone of the eye, and positioned for temporary eye vision corrective use, in conjunction with said existing lens,
- d) determining that said inserted second lens is more corrective of vision than said first lens,
- e) and effecting attachment of the second lens to eye structure to maintain the second lens in permanent position for use and in spaced relation to said existing lens and to the iris of the eye.
