We present the case of a patient who had refractive corneal inlay implantation for near vision improvement after bilateral cataract surgery. The patient had a history of bilateral cataract, and a 2-step procedure was suggested to improve her near and distance visual acuities. The first step was bilateral cataract extraction with a power target of plano intraocular lens implantation. Six months later, a refractive corneal inlay, Presbia Microlens, was implanted in the nondominant eye in the intracorneal pocket made with the femtosecond laser. No intraoperative or postoperative complications occurred. The bilateral uncorrected near visual acuity improved from less than Jaeger (J)6 to J1 and remained stable during the 2-year follow-up. The refractive corneal inlay is a safe, simple, and efficient method for improving near visual acuity in patients after cataract surgery.

UI MeSH Term Description Entries
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D009216 Myopia A refractive error in which rays of light entering the EYE parallel to the optic axis are brought to a focus in front of the RETINA when accommodation (ACCOMMODATION, OCULAR) is relaxed. This results from an overly curved CORNEA or from the eyeball being too long from front to back. It is also called nearsightedness. Nearsightedness,Myopias,Nearsightednesses
D011145 Polyvinyls POLYMERS derived from the monomer VINYL COMPOUNDS. Polyvinyl
D003319 Corneal Stroma The lamellated connective tissue constituting the thickest layer of the cornea between the Bowman and Descemet membranes. Corneal Stromas,Stroma, Corneal,Stromas, Corneal
D005260 Female Females
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D014792 Visual Acuity Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast. Acuities, Visual,Acuity, Visual,Visual Acuities
D018918 Phacoemulsification A procedure for removal of the crystalline lens in cataract surgery in which an anterior capsulectomy is performed by means of a needle inserted through a small incision at the temporal limbus, allowing the lens contents to fall through the dilated pupil into the anterior chamber where they are broken up by the use of ultrasound and aspirated out of the eye through the incision. (Cline, et al., Dictionary of Visual Science, 4th ed & In Focus 1993;1(1):1) Phacoemulsifications
D019654 Lens Implantation, Intraocular Insertion of an artificial lens to replace the natural CRYSTALLINE LENS after CATARACT EXTRACTION or to supplement the natural lens which is left in place. Implantation, Intraocular Lens,Implantations, Intraocular Lens,Intraocular Lens Implantation,Intraocular Lens Implantations,Lens Implantations, Intraocular
D019736 Prostheses and Implants Artificial substitutes for body parts, and materials inserted into tissue for functional, cosmetic, or therapeutic purposes. Prostheses can be functional, as in the case of artificial arms and legs, or cosmetic, as in the case of an artificial eye. Implants, all surgically inserted or grafted into the body, tend to be used therapeutically. IMPLANTS, EXPERIMENTAL is available for those used experimentally.
