Definitions
- the present invention relates to optical lens holders used for performing tests or other processes on the lens. More particularly, the present invention relates to a holder for supporting an accommodating intraocular lens device having at least two optics interconnected by one or more haptics. Intraocular lenses having a single optic have been known and used for many years. More recently, accommodating intraocular lens devices having two optics interconnected by one or more haptics have been disclosed in the following U.S. patents and applications to Faezeh Sarfarazi, the entirety of which are incorporated herein by reference:
- the Sarfarazi accommodating lens device includes two optics, one negative and the other positive for placing in the evacuated lens capsule of an eye.
- the optics are interconnected along their peripheries by one or more haptics which space the optics from each other and assist in properly positioning the device in the eye.
- the haptics are fomied from a flexible material such that they may flex in response to forces exerted by the eye's ciliary muscles which control accommodation. The haptics will thus flex and bow further radially outwardly upon a compressive force being applied to the device, whereby the two optics are drawn closer together to achieve an accommodative effect in the eye.
- the optics must be able to be moved in a manner simulating their accommodative movements in the eye.
- the holder for such a device must therefore be able to hold the device stationary while also allowing relative movement of the optics.
- manufacturing process steps may need to be carried out such as polishing, for example.
- the holder should therefore also be able to support the device during manufacturing process steps without damage to the device.
- the present invention provides a holder for supporting a two optic accommodating intraocular lens device.
- the holder is capable of holding the device while taking measurements or performing manufacturing process steps on the device.
- the holder supports the posterior optic periphery with the haptics and anterior optic extending freely therefrom and untouched by the holder. As such, testing and/or processing of the optics during their accommodative and unaccomodative positions may be taken.
- the holder includes a fixture having at least one but preferably three lens holding elements attached to the fixture, whereby the intraocular lens device may be removably attached to the holder by engaging the periphery of the posterior optic on the lens holding elements of the fixture.
- the lens holding elements may be integrally formed with the fixture or attached separately to the fixture.
- the lens holding elements each include a radial inward projection which together at their inward edges define an opening having a diameter slightly smaller than the outer diameter of the lens optic.
- the optic periphery may be pressed past the projections onto the fixture and thereby allow the intraocular lens device to be alternately mounted and dismounted from the holder.
- the amount of deformation required for the optic periphery to pass the projections is small enough so as to not damage the lens.
- Figure 1A is a perspective view of an embodiment of an accommodative intraocular lens which may be supported by the holder of the present invention
- Figure IB is a plan view thereof
- Figure 1C is a side elevational view thereof;
- Figure 2A is a perspective view of a first embodiment of the inventive fixture
- Figure 2B is a cross-sectional view as taken along the line 2B-2B in Fig. 2A
- Figure 3 is a perspective view of the fixture of Figs. 2A,B positioned in a horizontal fixture holder;
- Figure 4 is a perspective view of the fixture of Figs. 2A,B positioned in a vertical fixture holder;
- Figure 5 is perspective view an a second embodiment of the inventive fixture.
- Figure 6 is the view of Fig. 5 showing an accommodating IOL positioned on the fixture in the intended manner.
- lens device 10 includes first and second optics 12, 14 interconnected by one or more, but preferably three haptics 16a, 16b and 16c defining three open spaces 18a, 18b, 18c therebetween, respectively.
- Haptics 16a-c bow outwardly past the optic perimeters 12p, 14p and are flexible whereby the optics may move alternately toward and away from each other generally along the optical axis x-x.
- Optics 12, 14 are preferably flexible and may be made of any suitable IOL lens material.
- FIGS 1A and 1C show the space "S" between the optics 12, 14 which gets smaller as the optics move toward one another and larger as the optics move away from one another.
- the present invention is a holder for a lens device and therefore the particular optic and haptic configurations of a lens device which may be supported by the inventive holder may vary from that shown and described herein.
- a first embodiment of the fixture is indicated generally by reference numeral 20.
- Fixture 20 includes a central support surface 22a surrounded by at least one, but preferably three annularly spaced lens holding elements 24a, 24b and 24c.
- support surface 22a is circular and may be raised relative to outlying subsurface 22b.
- the lens holding elements 24a-c thus define tliree spaces Sa, Sb and Sc therebetween wherein the haptics 16a-c of lens element 10 are positioned.
- the width Wi (Fig. 2B) of spaces Sa-c needs to be slightly larger than the haptic width W 2 (Fig. IB) to allow the haptics 16a-c to pass freely within the spaces Sa-c defined between the lens holding elements 24a-c, respectively.
- each lens holding element 24a-c is itself annularly curved about support surface 22a with the outermost ends 24a'-c' thereof having a dovetail shape.
- Diametrically opposed inner-most tips "T" of the lens holding elements define a diameter Di (Fig. 2A) which is slightly smaller than the outermost diameter D 2 -(Fig. 1C) of the posterior optic 14.
- Di the outermost diameter
- D 2 -(Fig. 1C) of the posterior optic 14 the peripheral edge 14a of posterior optic 14 may be safely pressed past the inner most tips "T” of the dovetail until the posterior optic 14 is seated upon surface 22a.
- the dovetail shape of the lens holding elements secure the optic 14 to the fixture and thus the entire lens device 10 is held securely thereby as seen in Figs. 3 and 4. In this secured condition, the haptics 16a-c and anterior optic 12 extend freely upward from the captured posterior optic 14.
- fixture 20 may further include means for removably mounting fixture 20 to a fixture holder 30 which itself may be removably mounted to other testing and/or processing equipment such as an optical bench, for example (not shown).
- the fixture holder 30 includes a circular recess 32 wherein the circumference of fixture support side wall 22c may fit.
- Cooperative flats 22d and 34 (Figs 2A and 3) on the fixture 20 and fixture holder 30, respectively, may be provided for establishing the correct rotational position of the fixture within the holder.
- a slot 36 may extend from recess 32 for access by a tweezer or other tool to assist in loading and unloading the fixture 20 from the fixture holder 30. It will be appreciated that by making the fixture 20 and fixture holder 30 removably mountable to other equipment, the fixture 20 may be conveniently moved from one work station to another when performing different tests or processes on the lens device 10.
- another embodiment of fixture holder is indicated by reference numeral 40.
- the main difference between fixture holder 30 and fixture holder 40 is that holder 30 is designed to hold the lens device in a horizontal orientation while holder 40 is designed to hold the lens device 10 in a vertical orientation.
- fixture 20 and lens device 10 The vertical positioning of fixture 20 and lens device 10 is achieved in holder 40 by a pair of side' arms 42 which engage the top surface of outlying support surface 22b.
- a vertical compression force may be applied to anterior optic 12 (normal to anterior optic 12) to flex the haptics 16a-c and thereby mimic accommodation of the device 10 for testing purposes.
- a horizontal compression force may be applied against anterior optic 12 (again normal to anterior optic 14) to flex haptics 16a-c and thereby mimic accommodation of the device 10 for testing purposes.
- Figures 5 and 6 show another embodiment of the fixture indicated by the reference numeral 50.
- Fixture 50 is similar to fixture 20 with the difference being the shape of the lens holding elements.
- the lens holding elements are shaped as pinions 52a-c each having a top cap 52a'-c'.
- the periphery 14a of the posterior optic 14 may be safely pressed past the caps 52a'-c' to seat posterior optic 14 on support surface 54 with the haptics 16a-c extending in between the pinions 52a-c as seen in Fig. 6. It is thus understood that the fixture holder may take a variety of configurations and the invention is not to be limited to the exact configuration shown and described herein.
