Definitions
- the present invention relates to toric lens technology and more particularly relates to a toric lens which employs non-spherical surfaces including aspheric topography which produces a depth of field effect which reduces or neutralises axis mislocation of the lens and improves the astigmatic lens axis stability latitudes.
- the major principle involved in correcting astigmatism is accurately aligning the manufactured power meridians of the lens with specific meridians in the eye. If this is not done accurately, a resultant misalignment error occurs (i.e. the incorrectly aligned lens powers and the refractive powers of the eye combine to create totally different powers from which the eye needs to attain correct vision) preventing proper correction of astigmatism.
- This accuracy is determined by how closely the axis of powers in the lens aligns with those of the eye.
- the contact lens Practitioner can refract the astigmatic eye to within one degree of accuracy.
- the manufacturer should be able to control his lens accuracy to within 5 degrees. This is generally accepted as an industry standard. If however the lens does not position exactly on the axis when in vivo then a misalignment error occurs. Even with the 5 degrees manufacturing tolerance, a misalignment error can occur but will generally be accepted by the patient if the cylindrical component of their astigmatism is relatively low (eg. around -2.00 diopters or lower) .
- the lens swings 10 degrees or more in vivo due to physiological forces exerted during blinking, eye turning, retropulsion of the eye during blinking or similar, then the patients vision will be compromised.
- Spherical aberration is a common optical phenomenon associated with spherical surfaces. Spherical aberration occurs when rays passing through the periphery of the lens are deviated more than those passing through the paraxial zone. The prismatic effect of a spherical lens is least in the paraxial zone and increases towards the periphery of the lens. It reduces the clarity and luminence of objects focussed by optical elements which are of a spherically surfaced nature. Most cameras and telescopes etc. utilise aspheric or doublet lens systems to reduce or eliminate this spherical aberration.
- a doublet consists of a principal lens and a somewhat weaker lens of different refractive index cemented together.
- the weaker lens must be of opposite power, and because it too has spherical aberration, it will reduce the power of the periphery of the principal lens more than the central zone.
- This lens design can be manufactured by all the normal methods available to manufacturers, but will also suit more advanced technologies such as the use of bi-refringence. It is generally preferred that this technology be used on the anterior surface of the lens due to greater refractive index difference afforded by the air/lens interface, but this is not mandatory.
- a combination of front and back surface topography with both surfaces being changed from spherical can be utilised. So too can back surface topography changes be used effectively. This would especially suit diffractive or diffractive/Aspheric optical techniques. This is like the lens creating an Instamatic camera type effect on the eye whereby the wearer can focus cleanly on near objects and far objects with little compromise of both.
- the present invention seeks to overcome the aforesaid problems by providing a toric lens which reduces or eliminates the misalignment effect which occurs when a toric lens mislocates on the astigmatic eye and which will stabilise in vivo to within a few degrees but which is still thin enough to afford the cornea enough oxygen for satisfactory morphology and to provide good comfort * _and good cosmesis.
- a thick toric lens i.e. one which will stabilise in a satisfactory manner would have a prism or wedge peak thickness of 0.03 mm to 0.45 mm, whereas a thin version of the same lens would be around 0 . 15 mm to 0 .25 mm.
- the toric lens according to the present invention satisfies most or all of the above criteria but also provides a built in latitude of axis location by usage of complex aspheric optical topography.
- the present invention comprises: a toric lens for axis mislocation correction having optical topography on the surface/s of the lens which induces a depth of field, effect on the eye and enables the axis of powers on the lens to align with those on the eye of the wearer such that it neutralises mislocation error if the lens mislocates 1 degree or more said lens being thin enough to allow sufficient oxygen transmission therethrough to provide satisfactory morphology of the eye of a wearer.
- the depth of field effect is produced by aspheric optical topography however the same or a similar effect may be produced by Spline Curve Functions, Diffractive Optics (by Eschelets or similar) or Ion implantation or similar or Bi - refringence optics.
- Spline Curve Function is a method of describing a complex, non spherical curve via the use of weigh points or X Y co ordinates.
- a Spline curve is the smoothest possible curve between these points.
- Diffractive optics are the reverse of refractive optics. Light entering the optical element is split (generally by 1/2 wave length) and then re continued at any given focal length. Miniature prisms or eschelets are used for this purpose.
- Ion implantation is the implantation of one medium into another medium to change its physical characteristics. In an optical sense, implants a medium of a higher or lower refractive index in specific areas in order to specifically create different focal lengths. This can be achieved via the use of a particle accelerator or similar.
- Bi-refringence is a phenomenon where a medium can have two focal lengths at the one time. In nature this occurs in crystals (which are naturally bi-refringent) . So too is silicone which is why they make good computer chips. Specifically induced stress at opposing axis can induce bi-refringence in a number of elements.
- lenses are produced with an aspheric surface or surfaces with the nature and amount of asphericity being dictated by the depth of field effect required to neutralise the mislocation error. For a given toric lens power which creates a given amount of mislocation error an aspheric lens with the requisite depth of field effect will neutralise this mislocation.
- an aspheric or multi-aspheric surfaces lens can create a depth of field effect on the eye of approximately plus or minus 1.50 spherical diopters and is manufactured in toric form and a spherical toric lens with a power of -2.00/-1.50.xl80 mislocates by 10 degrees from the required axis and therefore creates a mislocation error of +0.26/-0.25 x 130 then the depth of field effect of the aspheric toric lens will neutralize this error.
- -2.00 is the power in the meridian of the lens of 90° to 270° and in the meridian of 0° - 180° the power is - 3.50.
- -2.00/-1.50 x 180 may be written overall as -2.00/-3.50 x 180.
- the eye needs -2.00/-1.50 x 180 for perfect vision.
- a lens with this power sits exactly on this axis i.e. 0 - 180 this power requirement is fulfilled.
- the meridians do not line up and an additional power over the top is needed to correct the eye, that power is called overrefraction.
- the overrefractions are simply resultant powers which occur when the lens mislocates and does not correct the eye's power.
- any overrefraction whether it be a simple crossed cylinder or a more complex lens over an under corrected or over corrected refraction, will be compensated by up to +0.75 in either spherical or cylindrical meridians, for example +0.75/-1.50 (Composite Powers: not meridignal) .
- Toric lenses are by virtue of their complexity difficult to manufacture. The leads to a higher scrap rate and an end higher cost to the practitioner. They are much harder to hold to accurate power tolerances as there are two main power meridians to control as opposed to a sphere where there is only one. Most manufacturers still try to hold their lenses to spherical lens tolerances in both meridians but sometimes this is not possible. This therefore leads to a visual compromise even if the lens locates accurately. This design would also compensate for this inherent problem in manufacture.
