Abstract
The present document discloses an accommodative, intraocular, combination to be implanted in the sulcus plane of the human eye with the combination comprising, 5 firstly, at least one accommodative lens, and, secondly, at least one supportive ring adapted to be implanted in the sulcus plane which supportive ring can be coupled to the sclera of the eye by anchors which anchors can penetrate the sclera of the eye.
Description
Accommodative combination to position a lens in the sulcus of the human eye The present document discloses an accommodative, intraocular, combination to be implanted in the sulcus plane of the human eye with the combination comprising, firstly, at least one accommodative lens, also: ‘lens’, having an optical axis with the lens comprising at least two optical elements of which at least one element is adapted to translate in at least one direction perpendicular to the optical axis with the optical surfaces of at least two elements adapted to vary at least one optical aberration of the lens with a degree of variation which is dependent on the degree of shift of the at least one of the optical elements, with the primary aberration to be varied being accommodation, meaning: variable defocus of the eye the combination also comprising, secondly, at least one supportive ring adapted to be implanted in the sulcus plane of the eye.
Such accommodating, translating, AIOLs are known from other documents, for example from NL2012133, NL201242, EP1871299, EP1932492, for designs of such AIOLs, and, for clinical results, Alio, in Am J Ophthamol 2016 Apr, 164: 37-48, with such documents not restricted hereto these documents referred to above.
These AlOLs are restricted to the concept which includes at least two cubic optical surfaces, meaning: Zernike third order surfaces, of which the basic, free-form, non- rotational symmetric, shapes are known from Alvarez US3305294, which provides the original concept for a variable lens, for laterally shifting optical elements, and Baker CA1252655, for derived fan-like rotational shifting optical elements. More precisely, in mathematics, these are all various variations on the basic formula according to Alvarez, t=A(xy2+x3/3, see US3305294 for details and notations). Such lenses can also provide, by movement of at least one of the optical elements, a variable extension of accommodation, and/or variable focus, and/or variable spherical aberration. Such movement can be achieved, but not restricted to, principles as disclosed in US2009062912 and WO2005084587, and the same concept, with various adaptations in, for example, US2014074233, WO2014058316, EP2765952, NL2012257278, US2010131955, US2010106245,
NL1029548 and references made therein and related documents, which principles have now been shown to function well in the human eye. The present document discloses an accommodative combination to be implanted in the sulcus plane of the human eye with the combination comprising, firstly, at least one accommodative lens , also: ‘lens’, having an optical axis with the lens comprising at least two optical elements of which at least one element is adapted to translate in at least one direction perpendicular to the optical axis with the optical surfaces of at least two elements adapted to vary at least one optical aberration of the lens with a degree of variation which is dependent on the degree of shift of the at least one of the optical elements, with the primary aberration to be varied being accommodation, meaning: variable defocus of the eye the combination also comprising, secondly, at least one supportive ring adapted to be implanted in the sulcus plane of the eye.
The supportive ring can be independent, meaning: not any component of the supportive ring is coupled to any component of the lens, or, alternatively, the supportive ring can be dependent, meaning: that at least one component of the supportive ring is firmly coupled to at least one component of the lens, with, for example, a pin-in hole connection. The supportive ring coupled to the sclera of the eye, for example, with the supportive ring firmly coupled to the sclera of the eye by anchors penetrating into the sclera of the eye.
The at least one haptic of the lens can be coupled to a natural component of the eye which component is the ciliary mass of the eye, or alternatively, the at least one haptic of the lens can be coupled to the capsular bag of the eye, or, alternatively, the at least one haptic of the lens can be coupled to a natural component of the eye which component is the zonula network of the eye, or, alternatively, the at least one haptic of the lens can be coupled to a natural component of the eye which component is the iris of the eye, or, alternatively, the at least one haptic is adapted to can translate at least one of the optical elements by liquid pressure generated in the posterior chamber of the eye, or, alternatively, the at least one haptic is coupled to a MEMS, meaning: micro-electro-mechanical system, which MEMS is adapted to provide movement of at least one optical element of the lens.
The accommodative combination can comprises at least one haptic adapted to urge the optical element back to a resting position, a position of decreased optical power, when the driving means are inactive.
Also, the optical elements can also comprise at least one optical surface adapted to correct for any fixed optical disorder of the eye, with the the fixed optical disorder can be presbyopia, meaning: ‘reading far-sightedness’. Also, the accommodative combination is adapted for implant in the human eye can correct for at least one variable optical disorder of the eye other than defocus.
The accommodative combination can correct for any variable disorder which is is a variable disorder generated by the lens, and, also, the accommodative combination can provide correction of any combination of at least one variable and at least one fixed disorder of the eye.
The accommodative combination, the supportive ring and the lens, can comprise at least one toric optical surface to provide correction of astigmatism of the eye with the lens and the supportive ring both comprising at least one coupling component to fix the rotational angle of the lens versus the rotational angle of the supportive ring.
