Definitions

  • the present invention relates to contact lenses and more particularly relates to an improvement in the conventionally known designs of contact lenses which improves lens behaviour on the eye of a wearer.
  • a contact lens sits in apposition with the cornea or the sclera or both. It is desirable that a lens be able to transmit or allow the passage of oxygen to reach the eye so that natural conditions can be maintained as far as is practicable near the eye and on the eye surface.
  • the prior art lenses achieve orientation by two main methods.
  • the first relates to prism formation in the lens. This is achieved by machining of the lens surface to allow the eye lids to complement the lens surface configuration thereby assisting in proper location of the lens. In one configuration the lens is thickened towards the bottom.
  • SUBSTITUTE SHEET j The second method of lens orientation is achieved by zonal thinning. In this case, the top and bottom peripheral areas of the lens are thinned by machining. The eye lid pressure then moves the lens around to find the line of least resistance to thereby hold the lens in the correctly oriented position.
  • the former method of lens orientation suffers from a number of disadvantages namely; the aforesaid thickened portion or portions of the lens may prevent adequate oxygen transmission through the lens. This can result in oedema or corneal neovascularisation. Another consequence of the lens thickening is wearer discomfort.
  • the zonal thinning method also has disadvantages. Namely using this method it is difficult to make a lens to the required degree of accuracy and reproducability. The degree of orientation accuracy is not always as good as required and zonal thinning does not work well for high positive powered corrections due to the thinness of the periphery of the lens.
  • the present invention seeks to overcome the aforesaid disadvantages by providing a lens having grooves and/or patterns and/or holes (fenestrations), forming grooves in the front or back surfaces of the lens.
  • the grooves and/or patterns are manufactured into the lens so that they are either proud of or indented into the lens surface according to selected design parameters.
  • the grooves and/or patterns aid in the correct orientation of the lens on the eye and increase gaseous transmission through the lens.
  • there are a series of grooves, patterns or fenestrations on the lens which are held by the upper eye lid thus aiding lens orientation.
  • the spongy palpebral and/or tarsal bubar conjunctiva grips the indentation in the lens surface and orientates the lens by following the slope of the pattern, grooves or hole fenestrations.
  • the grooves and/or patterns and/or fenestrations formed on the lens facilitate proper orientation on the eye and without compromise to the relationship between
  • the invention comprises: a contact lens of the type having a toroidal surface, said lens having either random grooves disposed in a regular or irregular array and of constant or variable length, depth and width, or random patterns formed in the back or front surface of the lens.
  • the invention comprises: a lens having at least one groove in either its front or back or both surfaces, said groove or grooves providing a discontinuity in the thickness in the lens at the location of the grooves, said grooves providing a means for location of the lens on an eye.
  • the invention comprises a contact lens having formed on either the back or front or both surfaces at least one patterned formation said patterned formation or formations providing a means to enable proper location of the lens on an eye.
  • the present invention comprises an improved contact lens characterised in that the lens comprises at least one pattern and/or opening in the lens and/or at least one groove in or on either the back or front surface of the lens, said at least one pattern and/or opening and/or groove in combination or individually providing a means to enable proper location and orientation of a lens on the eye of a wearer by engagement between said lens, said eye and an eyelid thereby facilitating the increased transmission of gas through said lens.
  • the grooves, and/or patterns and/or openings are arranged so as to allow the eyelid of a wearer to follow the contours of the said grooves and/or patterns and/or openings to enable the proper orientation of the lens on the eye.
  • the grooves are parallel and formed in series near the edge of the lens.
  • the grooves can be disposed in a radial array around the periphery of the lens or merely disposed randomly across either the front or back surface of the lens.
  • patterns are formed at any position on the lens surface either back or front or both according to user requirements.
  • the grooves and/or patterns marked on the back surface on the lens to eliminate the potential for Vivo protein deposition.
  • the natural flexibility of the lens will transfer the groove or pattern effect through to the front surface of the lens and thereby interact with the spongy tarsal conjunctiva.
  • This method or orientation and/or specific modulas can be caused by specific interaction with the upper and/or lower tarsal conjunctiva, the interaction with the palpebral conjunctiva or a combination of various in vivo physiological forces which may or may not include one or both or a combination of the above mentioned forces.
  • This design is a method or harnessing lid forces and various physiological forces pertaining specifically to the eye and its various movements and actions.
  • the patterns or grooves may be raised proud of the surrounding surfaces or can be indented into these surfaces or can be a combination of both.
  • the patterns may be in any shape or form.
  • the patterns or shapes whether they be raised above the surrounding surfaces or indented below the surfaces can be used to prevent and/or alleviate the "binding" of rigid lenses or silicone (or similar) lenses on the cornea during wear. Binding is a known phenomenon and results in fitting complications in this type of lens wear. It can lead to epithelial denuding of the cornea with consequent risk of infection or ulceration. It can cause ocular problems such as anoxia and/or oedema during wear.
  • the grooves, holes or patterns have the effect of alleviating the binding effect.
  • the fenestrations or holes may be included either in conjunction with the patterns or they may constitute the role method of lens stabilisation.
  • the grooves or patterns can be used to move the lens in a specific fashion to create bifocal effects, for example alternating vision.
  • Figure 1 shows a front elevational view of a contact lens according to one embodiment of the invention.
  • Figure 2 shows a front elevational view of a contact lens according to an alternative embodiment.
  • Figure 3 shows a front elevational view of a contact lens according to an alternative embodiment.
  • Figure 4 shows further possible embodiments of the invention.
  • FIG. 1 there is shown a contact lens 1 having an array of parallel grooves 2 disposed in an upper half segment of the lens.
  • the array shown is one possible embodiment only and it is envisaged that there is almost no limit to the number of groove permutations and combinations.
  • the grooves can be of varying lengths, depths and widths according to particular user requirements.
  • Figures 2 and 3 show further embodiments of the invention but this time there are patterns 3 and 4 respectively formed on the surface of the lens. Again, as with the grooves, there is virtually a limitless number of possible patterns which can be formed.
  • the lens can be configured with a combination of grooves, holes and patterns according to user requirements.
  • the grooves and patterns can be formed according to any particular shape, depth configuration or combination.
  • the use of the grooves and patterns essentially has a twofold purpose. Firstly, they provide a facility for increasing (locally, if necessary) the oxygen transmission through the lens. Secondly, they provide means to enable effective and accurate lens location on the eye, also taking into account the physiological response in the eye. To this end the pattern, groove or hole configuration will often be dictated by the physiology of the eye of the wearer.
  • Oxygen deprivation in the eye can cause long term eye damage and the present invention seeks to alleviate this problem which existed with prior art lens designs.
  • the physiology of the eye and eyelid interrelation is critical to the operation of the lens of the present invention. Nearly a third of the thickness of the eyelid is made up of the striated orbicularis oculi muscle, which is bordered anteriorly and posteriorly by loose non-adipose connective tissue.
  • the orbicularis is a thin muscle surrounding the palpebral aperture and extending well beyond the orbital margin on to the face.
  • the muscle is divisible into orbital and palpebral portions.
  • the orbital portion lying beyond the orbital margin with the palpebral portion lying within it.
  • lid pressure is utilised to provide a frictional force to orientate the lens. This is achieved by means of either a raised or lowered area at the peripheral, horizontal area of the lens as hereinbefore described.
  • a small raised zone or depressed zone is utilised leaving the average lens thickness similar or close to a non astigmatic lens of similar power.
  • the raised or depressed areas may be lathe cut or even produced as multiple fenestrations. However they are best created by moulding or laser sculpturing.
  • a depression is created in the superior lens area by moulding or laser sculpturing.
  • lid pressure forces the soft conjunctiva into the
  • Superior depressions in the lens could also be used to change the axis of an incorrectly locating astigmatic lens.
  • the grooves and patterns can be formed by any one of a number of processes, including but not limited to: a) Laser Engraving; b) Mechanical Engraving; c) Moulding; and d) Spincasting.
  • the laser or mechanical engraving techniques can utilise manual or computer controlled facilities according to requirements.
  • the moulding method employs conventional moulding techniques whereby the lens profile is formed by a minor profile in the mould. Conventional techniques are also employed with the spin casting method.
