Abstract
An ophthalmic prosthetic and method for correcting negative and positive dysphotopsia. The ophthalmic prosthetic comprises a peripheral light blocking implant member adapted to locate in a gap between an iris and an intraocular implant lens. The gap is between the anterior surface of the lens and the posterior portion of the iris. An opacity of the peripheral light blocking implant member is selectively positioned to block passage of light.
Claims11
A method for correcting negative and positive dysphotopsia for a person in need of correction of or at risk for positive and negative dysphotopsia caused by light passing between an iris or ciliary body and an intraocular lens of an eye, the method comprising:
- forming an incision in a cornea,
- inserting an ophthalmic prosthetic, which includes an annular body or an annular segment, into the eye, between the iris and the intraocular lens, through the incision, and
- locating the annular body or annular segment either within a capsular bag or within a ciliary sulcus, to completely fill an axial gap and/or substantially fill a radial gap between the iris and the intraocular lens and block the light, which travels through the pupil and tangentially to the intraocular lens, from striking or bypassing a circumferential edge of the intraocular lens and striking an anterior retina, the axial and/or radial gap being present prior to the inserting of the ophthalmic prosthetic into the eye, and
- wherein the ophthalmic prosthetic has anterior and posterior surfaces that are both located anteriorly of the intraocular lens.
A method for correcting negative and positive dysphotopsia for a person in need of correction of or at risk for positive and negative dysphotopsia caused by light passing between an iris or ciliary body and an intraocular lens of an eye, the method comprising:
- forming an incision in a cornea,
- inserting an ophthalmic prosthetic, which includes an annular body or an annular segment, into the eye, between the iris and the intraocular lens, through the incision, and
- locating the annular body or annular segment either within a capsular bag or within a ciliary sulcus, to completely fill an axial gap and/or substantially fill a radial gap between the iris and the intraocular lens and block the light, which travels through the pupil and tangentially to the intraocular lens, from striking or bypassing a circumferential edge of the intraocular lens and striking an anterior retina, the axial and/or radial gap being present prior to the inserting of the ophthalmic prosthetic into the eye;
- and
- wherein the annular body or annular segment of the ophthalmic prosthetic has an outer diameter that fills the radial gap in a coronal plane of the eye and/or the ophthalmic prosthetic has a thickness of about 0.05 mm to about 1.2 mm such that the axial gap is filled;
- and
- wherein the ophthalmic prosthetic has anterior and posterior surfaces that are both located anteriorly of the intraocular lens.
