Abstract: One embodiment of the present invention is a method for determining whether to perform a phakic intraocular lens implant procedure, which method includes: (a) obtaining an image of an anterior segment of an eye; (b) determining a distance from a crystalline lens to another part of an anterior chamber from the image; and (c) comparing the distance with a predetermined value.

Abstract: A method for treating presbyopia in the eye of a patient includes the step of applying energy to the zonula to weaken the zonula tension or the tension exerted on the zonula sufficiently to reverse the symptoms of presbyopia in the eye. In one example of the method, the energy applied to the zonula is electromagnetic energy, such as provided by a suitable laser.

Abstract: A method for implanting a corrective element into the sclera of an eye for the treatment of presbyopia comprises the steps of (a) identifying an optimum implantation location by pressing against different alternative locations along the sclera until a marked shifting of the equator of the crystalline lens is observed, and (b) implanting a corrective element within the sclera at the optimum location.

Abstract: A method for making an incision into the sclera of an eye includes the steps of (a) applying pressure to a portion of the surface of the sclera to flatten that portion of the sclera, (b) cutting an incision in the sclera with a linear blade along a line parallel to the flattened surface of the sclera, and (c) releasing the pressure on the portion of the surface of the sclera to allow the sclera to return to its natural curvature. By this method, the incision cut into the sclera in step (b) takes on a curvature which parallels the natural curvature of the sclera. The method can be carried out using a tool which includes (a) a generally smooth scleral flattening surface disposed within a flat, flattening surface plane, and (b) a generally linear incision blade having a sharpened free end. The incision blade is disposed generally parallel with the flattening surface and spaced apart from the flattening surface by a distance of between about 0.5 mm and about 0.8 mm.

Abstract: A corrective element useful in the treatment of presbyopia has an hourglass shape.

Abstract: Ocular implant of the type comprising an optical portion to which there is connected a haptic portion arranged to position the focal axis of the optical portion off-center with respect to the geometric axis of the eye, towards the nasal side, provided for insertion into a phakic eye to correct presbyopia, its optical portion having, at least in its central region (7), a multifocal treatment constituting an addition of from +1 to +3.5 diopters, and its haptic portion (6) ensuring that the focal axis (9) of the optical portion (5) is arranged from 0 to 0.75 mm off-center when the implant is in position in the eye.

Abstract: The disclosure concerns a scleral expansion segment of the type consisting of an arched rod designed to be placed on the sclera perpendicular to the ciliary body. The free ends of said rod have a spatula shape wider than the diameter of said bridge, so as to constitute wide support bases.

Abstract: Presbyopia is more effectively corrected by techniques and implants designed to exert an inwardly-directed force on the ciliary body. The force is preferably either perpendicular to the optical axis, or generally perpendicular wherein the zonular plexus is deflected inwardly approximately along an axis bisecting the angle described by the anterior zonular fibers when viewed in a horizontal plane.

Abstract: The corrective element (3) is adapted to be implanted in an eye in line with the ciliary body and is shaped, to exert on the ciliary body a centripetal force (F1) directed perpendicularly to the optical axis (2) of the eye.

Abstract: A scleral expansion segment consists of an arched rod designed to be placed on the sclera perpendicular to the ciliary body. The arched rod has a pair of free ends connected by a bridge. The free ends have a spatula shape wider than the diameter of the bridge, so as to constitute wide support bases.

Abstract: A corrective element (3) is intended to be implanted in an eye opposite the ciliary body and is shaped to exert on said ciliary body a pressure (F1) directed perpendicular to the optical axis (2) of the eye.

Abstract: In the connection zone, the portion of the haptic part connected to the optic part is situated on the edge of the optic part. The optic part consists of a flexible lens which can be folded or rolled upon insertion of the implant into the anterior chamber. The haptic part has a general form of the number 2 and has an upper free end, a bend, and a lower free end. In the connection zone, the connection between the optic part and the haptic part is rigid.

Abstract: The invention provides an anterior chamber implant for treating a phakic eye having an optical part connected to loops. The loops have an arc-shaped profile with a double radius of curvature. The radius of curvature of the proximal portion being greater than that of the distal portion.

Abstract: The invention concerns an intraocular implant (10) comprising a substantially circular optical part (12) made of a first flexible material enabling it to be folded along a diameter and a haptic part (20). The haptic part (20) comprises a substantially ring-shaped body (22), substantially concentric and coplanar to the optical part, the body (22) has an opening, a first free end (26) and a second connecting end (28), the body (22) being made of material more rigid than the first, and a base (24) connecting in substantially radial manner the second end (28) of the haptic part body to a peripheral zone (16) of the optical part.
