Intraocular implant with removable optic

Abstract

Intraocular implants and methods of forming intraocular implants are described herein. The intraocular implant can include a powered optic and a lens holder. The optic can be mechanically coupled to an inner periphery of the lens holder to form the intraocular implant. A portion of the lens holder can include a mask disposed about the optic to increase depth of focus in a human patient.

         29 . An ophthalmic implant comprising:
 a main body comprising a material substantially transparent to visible light, the main body comprising an outer periphery and an inner periphery, the inner periphery defining a through-hole extending from an anterior surface of the main body to a posterior surface of the main body, the through-hole configured to increase depth of focus in a human patient when the ophthalmic implant is implanted in an eye of the human patient; and   at least a portion of the main body being substantially opaque to visible light, the substantially opaque portion being disposed about the through-hole.   
     
     
         30 . The ophthalmic implant of  claim 29 , further comprising haptics extending from the main body for positioning the ophthalmic implant in the eye. 
     
     
         31 . The ophthalmic implant of  claim 29 , wherein the substantially opaque portion extends an entire thickness of the main body. 
     
     
         32 . The ophthalmic implant of  claim 29 , wherein the substantially opaque portion extends over the entire main body. 
     
     
         33 . The ophthalmic implant of  claim 29 , wherein the substantially opaque portion forms the inner periphery of the main body. 
     
     
         34 . The ophthalmic implant of  claim 29 , wherein the substantially opaque portion comprises a mask positioned around the through-hole. 
     
     
         35 . The ophthalmic implant of  claim 34 , wherein the mask is on the anterior surface of the main body. 
     
     
         36 . The ophthalmic implant of  claim 34 , wherein the mask is positioned between the anterior surface and the posterior surface of the main body. 
     
     
         37 . The ophthalmic implant of  claim 29 , wherein the main body comprises optical power. 
     
     
         38 . The ophthalmic implant of  claim 29 , wherein the substantially opaque portion comprises a photochromic material. 
     
     
         39 . The ophthalmic implant of  claim 29 , wherein the substantially opaque portion is temporarily darkened. 
     
     
         40 . The ophthalmic implant of  claim 29 , wherein the substantially opaque portion is substantially transparent to at least some non-visible electromagnetic radiation with a wavelength between 750 nm and about 1500 nm to facilitate examining ocular tissue posterior to the ophthalmic implant. 
     
     
         41 . The ophthalmic implant of  claim 29 , wherein the ophthalmic implant is fixated in the ciliary sulcus. 
     
     
         42 . The ophthalmic implant of  claim 29 , wherein the ophthalmic implant is integrally formed as one piece. 
     
     
         43 . The ophthalmic implant of  claim 29 , wherein the through-hole has a diameter between 0.85 mm and 2.2 mm. 
     
     
         44 . The ophthalmic implant of  claim 29 , further comprising an optic coupled with the main body. 
     
     
         45 . The ophthalmic implant of  claim 44 , wherein the optic is positioned in the through-hole and mechanically coupled with the inner periphery of the main body. 
     
     
         46 . The ophthalmic implant of  claim 44 , wherein the optic is a toric lens. 
     
     
         47 . A kit comprising:
 the ophthalmic implant of  claim 29 ; and   a plurality of optics with different optical powers, each of the plurality of optics configured to be coupled with the main body.   
     
     
         48 . The kit of  claim 47 , further comprising a plurality of the ophthalmic implants of  claim 29 , the plurality of ophthalmic implants being different sizes.
