Original ArticleThe IOL-Vip System: A Double Intraocular Lens Implant for Visual Rehabilitation of Patients with Macular Disease
Section snippets
Materials and Methods
The IOL-Vip System consists of 2 IOLs that reproduce an intraocular Galilean telescope: a high minus-power biconcave IOL (about −66 diopters [D]) in the capsular bag acts as the eyepiece, and a high plus-power biconvex IOL (about +55 D) in the anterior chamber (AC) acts as the objective. Both lenses are made of polymethyl methacrylate, have a 1-piece design, and provide ultraviolet light filtering. The optic of the 2 lenses is 5 mm in diameter, with a maximum axial thickness of 1.5 mm for the
Results
The double IOL surgical procedure was well tolerated in all cases, and the follow-up did not substantially differ from that of normal phacosurgery using a single IOL implant (Fig 2). The same was true for the procedure-related endothelial cell loss of 7% (mean preoperative count, 2716; mean postoperative count, 2513), evaluated in 38 of 40 patients at the end of a mean follow-up of 20 months (range, 7–35). It is worth noting that the patient with the lowest preoperative count, 1783 cells/mm2,
Discussion
There are various hereditary or acquired retinal disorders that give rise to macular degeneration, of which AMD is very frequent and the leading cause of legal blindness in developed countries. However, despite the frequency of these diseases the available treatments cannot prevent severe central vision loss in most cases, and impaired foveal function reduces patients’ ability to carry out everyday activities such as reading, writing, or grooming. Although most patients retain sufficient visual
