INTRODUCTION
Age-related macular degeneration (ARMD) is a leading cause of visual loss in adults older than 60 years.1 Once central vision has been seriously jeopardized, visual function can only be improved with optical devices that produce magnification of near and distant images. Koziol et al2 reported the use of a teledioptric lens implant with a high-minus central zone (2.5 mm). When this implant is used in combination with eyeglasses as part of a teledioptric system, the magnified visual field obtained is 2.6 times greater than that achieved using an external telescope (magnification power, x3; focusing distance, 50 cm; magnification power with the aid of external spectacles, x8; visual field, 6,6° equivalent to 20° in the retina). However, the disadvantages found when a combined telescopic system is used still occur. The implantable miniaturized telescope (IMT) (VisionCare Ophthalmic Technologies Ltd, Yehud, Israel) designed by Lipshitz et al3 should partially prevent the . . . [Full Text of this Article]
