The at least one anterior haptic restraint member includes a sulcus support portion, configured to be received in a sulcus of an eye, and haptic support portions, configured to block anterior movement of haptics of an intraocular device mounted in the sulcus fixation frame or fixate an IOL in the sulcus. ## Claims ### Claim 1 An intraocular assembly comprising: a sulcus fixation frame comprising at least one anterior restraint member to which a posterior intraocular device receiving member is coupled by means of coupling members, said at least one anterior restraint member comprising a sulcus support portion, configured to be received in a sulcus of an eye, and anterior blocking members, configured to block anterior movement of haptics of an intraocular device mounted in said sulcus fixation frame, wherein said anterior blocking members, said posterior intraocular device receiving member, and said coupling members are slender wires or filaments. ### Claim 2 (depends on 1) The intraocular assembly according to claim 1, wherein said sulcus support portion is curved. ### Claim 3 (depends on 1) The intraocular assembly according to claim 1, wherein said anterior blocking members are curved. ### Claim 4 (depends on 1) The intraocular assembly according to claim 1, wherein said anterior blocking members are straight. ### Claim 5 (depends on 1) The intraocular assembly according to claim 1, wherein said at least one anterior restraint member comprises a plurality of anterior restrain members, each anterior restrain member comprising a sulcus support position, wherein said sulcus support portions are coupled to each other by said anterior blocking members. ### Claim 6 (depends on 1) The intraocular assembly according to claim 1, wherein said at least one anterior restraint member comprises a plurality of anterior restraint members circumferentially spaced from each other symmetrically about a central anterior-posterior axis of said sulcus fixation frame. ### Claim 7 (depends on 1) The intraocular assembly according to claim 1, wherein said sulcus support portion comprises a suture receiving member. ### Claim 8 (depends on 1) The intraocular assembly according to claim 1, wherein each of said coupling members comprises an anterior end coupled to said sulcus support portion and a posterior end coupled to a perimeter of said posterior intraocular device receiving member. ### Claim 9 (depends on 8) The intraocular assembly according to claim 8, wherein each of said coupling members comprises an anterior straight portion extending from said anterior end, followed by a curved portion and ending in a posterior straight portion that extends to said posterior end. ### Claim 10 (depends on 1) The intraocular assembly according to claim 1, wherein said sulcus support portion comprises a suture receiving member and each of said coupling members comprises an anterior end coupled to said sulcus support portion and a posterior end coupled to a perimeter of said posterior intraocular device receiving member, and wherein said anterior end is coupled to said sulcus support portion at said suture receiving member. ### Claim 11 (depends on 1) The intraocular assembly according to claim 1, wherein said at least one anterior restraint member is a continuous 360° member. ### Claim 12 (depends on 1) The intraocular assembly according to claim 1, wherein said sulcus support portion and said anterior blocking members are all along a circumference of said at least one anterior restraint member. ### Claim 13 (depends on 1) The intraocular assembly according to claim 1, wherein said coupling members comprise intraocular device support members. ### Claim 14 (depends on 1) The intraocular assembly according to claim 1, wherein said at least one anterior restraint member comprises a radially-outer circumferential support portion that extends between outer ends of a pair of radial portions, and a radially-inner circumferential support portion that extends between inner ends of each said pair of radial portions. ### Claim 15 (depends on 14) The intraocular assembly according to claim 14, wherein said radially-outer circumferential support portion is circumferentially longer than a circumferential gap between adjacent radially-inner circumferential support portions. ### Claim 16 (depends on 1) The intraocular assembly according to claim 1, further comprising an intraocular device mounted in said sulcus fixation frame, wherein said intraocular device comprises haptics, and wherein said anterior blocking members are configured to block anterior movement of said haptics and a portion of said coupling members is configured to block posterior movement of said haptics. ### Claim 17 (depends on 16) The intraocular assembly according to claim 16, wherein said intraocular device is a cataract IOL. ### Claim 18 (depends on 16) The intraocular assembly according to claim 16, wherein said intraocular device is an Implantable Telescope or IOL. ### Claim 19 (depends on 16) The intraocular assembly according to claim 16, wherein said intraocular device is a toric IOL.
