    摘要: An apparatus in which a deformable or compressible intraocular lens can be received and staged for insertion into a patient's eye. The apparatus has an elongated compression chamber with proximal and distal ends and a longitudinal passageway, having an inner surface, extending between the ends. The portion of the passageway adjacent to the proximal end forms a loading area in which the passageway gradually decreases in size for causing an intraocular lens to be deformed or compressed as the lens is moved along the passageway. A staging area having a top and bottom passageway wall, communicates with the loading area with the passageway wall including alignment means for retaining the intraocular lens in a deformed or compressed condition. A portion of the passageway is sized to retain the intraocular lens in the deformed or compressed condition. A portion of the passageway defining the loading area comprises a surface which includes an opening and a slot or groove for permitting withdrawal of forceps used for pushing the intraocular lens through the loading area and into the staging area for deforming or compressing the lens.

    摘要: A low or high refractive index corneal inlay optical lens adapted to be inserted singly or multiply between the layers of a cornea to correct refractive errors in eyesight, wherein the implanted lens is a solid transparent uncoated lens having no apertures therethrough, of a diameter less than that of the optic zone of the eye under normal light or bright light conditions, such that the movement of fluids, nutrients and gases throughout the corneal layers is unimpeded, and wherein the composition of the lens or lenses relative to that of the surrounding stromal tissue are such that multiple refractive indices may be created and multiple focal corrections are possible.
