Title:
拡大共軸光学部を備えた二次用眼内レンズ
Document Type and Number:
Japanese Patent JP6525014
Kind Code:
B2
Abstract:
A secondary foldable intraocular lens, IOL, (2) is provided that is surgically implanted in addition to at least one primary IOL (1) in the patient's pseudo-phakic eye. The secondary IOL (2) is arranged optically coaxial to the primary IOL (1) focusing a combined image onto the retina (5) of the patient's eye (4) additionally magnifying at least a central part of the image of the primary IOL (1) projected onto the macula (6) of the retina (5). The secondary IOL (2) comprises one or more haptics (7) for fixing and stabilizing it within the sulcus ciliaris (8) of the patient's eye (4)—and an optically active portion (9) designed to project the image through the primary IOL (1) onto the retina (5). The optically active portion (9) of the secondary IOL (2) comprises a central optical portion (10) and a peripheral optical portion (11) extending around the central optical portion (10), forming two different, but coaxially positioned lenses from one block. The central optical portion (10) is designed to form a positive lens providing additional refraction of minimum 5D, up to maximum 25D to the refraction provided by the peripheral optical portion (11) of the secondary IOL (2).
