FIELD OF THE INVENTION

The present disclosure relates to an ophthalmic optical testing apparatus (OTA). More particularly, and not by way of limitation, the present disclosure is directed to a system and method for ophthalmic optical testing in which the human eye can be modeled in order to evaluate the performance of various ophthalmic options available to a patient prior to patient surgery, the performance of various intraocular lens (IOL) and/or lens under test (LUT) models, and/or the potential effect of light sources on the eye.

BACKGROUND AND PRIOR ART

Surgery that involves the eye (or related ophthalmic region of the eye) is often a stressful event for the patient and the surgeon. In some cases, different options might be available to the patient and it is currently difficult to evaluate the visual outcome of each option. Currently there is no methodology to explore these options and their outcomes absent actually performing surgery on the patient's eye. It would be helpful to the patient and physician to have a device where the effect of a given option may be evaluated in a model of the human eye prior to surgery. In this manner, a patient and physician may explore the performance of a variety of surgical options prior to committing to a selected surgical option.

The OTA also would also allow a lens manufacturer to test various models in a setting which replicates the human eye. The OTA would also allow the testing of light exposures on the retina or cornea.

The OTA mirrors the patient's physiology and the options available to the patient. The patient and physician can then view the optical results of each option and their concomitant results and make an informed choice. The same OTA can also be used to compare various measurement devices or calibrate different devices with each other. The OTA can be used by ophthalmic companies as an additional test for intraocular lenses (the "IOLs") in vitro. It can also be used for laser safety testing or to examine light hazards.

BRIEF SUMMARY OF THE INVENTION

The disclosed OTA invention permits the human eye to be modeled prior to performing actual patient surgery in order to evaluate a variety of possible ophthalmic patient treatment options. In this manner the patient's physiology can be mirrored in an ophthalmic eye model and then a variety of lens can be placed in the OTA to model and evaluate each lens option with respect to the desired patient outcome.

Using an appropriate measuring device, a physician can then decide if the lens the surgeon proposes is appropriate or needs to be adjusted to better serve the patient. The OTA provides a dry run on the visual effects created by the lens chosen by the doctor. The same OTA can also be used to compare measurement devices or calibrate different system, thus providing a better understanding of each system's capabilities, options, and limitations. Additionally the OTA can be used by ophthalmic companies as an additional validation test after "in-vitro" lab testing and prior to "in-vivo" implantation. Finally, the same OTA could be used to validate, compare, calibrate, or select ophthalmic measurement devices for use with a given patient or class of patients. The OTA can also be customized to reflect different corneal shapes and based upon a particular shape further adapt a visual solution for that particular patient.

The OTA disclosed herein generally consists of an adjustable platform on which an optical retention framework (ORF) is mounted. The ORF supports a plurality of lens- retaining structures in a lens alignment series (LAS). In its basic form the ORF incorporates a cassette support tower (CST) that retains a lens cassette fixture (LCF) holding a pupil lens fixture (PLF) that incorporates the equivalent of pinhole or light block device (POL) and/or pinhole/iris opening. To each side of the PLF are configured longitudinally adjustable platforms on which corneal lens optics (CLO) and intraocular lens (IOL) optics are held within corneal/IOL fixtures. The corneal lens may be adjusted based upon corneal measurements of the patient. This allows for the posterior and anterior lens distances to be adjusted as well as a variety of other distances in the longitudinal optical axis (LOA) pathway that is common to the CLO, PLO, and IOL.

Adjustment of the mechanical positioning of the CLO, PLO, and IOL as well as proper selection of these lenses allows a physician to evaluate a number of optical pathways for a patient prior to surgery.

Operation of the OTA is as follows: the physician places a lens which is modeled after the patient's cornea in the CLF, a lens modeled after the patient's pupil in the PLF and the IOL/LUT selected for the patient in the LUF. The slots can be adjusted by the set screws or automated linear stage system to replicate the physiology of the patient. Once the components have been properly positioned a light can be directed through the model and the image quality produced by the OTA with the components and adjustments selected for that test can be evaluated. Various aspects of patient eye physiology can be adjusted for each test done with the OTA including but not limited to anterior chamber depth ("ACD"), posterior chamber depth ("PCD"), the pupil opening, as well as the variable lens components comprising the cornea, pupil, and IOL. Different retina diffusion and thermal papers can be inserted along the LOA in slots provided by the ORF to evaluate theoretical thermal heat buildup from different procedures. The OTA can be used with class II and III devices to validate heat dissipation algorithms and safety factors.

Overview

There is a need for a device that allows for testing of a proposed IOL prior to the replacement of a human lens or the in-situ adjustment of a lens. For example, there is a need for a device (OTA) that is capable of modeling a human eye in a manner that can account for the size, lens shape, corneal shape, eye physiology, retina position, lens position, and/or other ophthalmic optical conditions. The OTA described herein also has the ability to test a variety of eye configurations, corneal structure, lens power, and lens shape.

Application Context System Overview (0100)

An overview of the application context for the present invention system is generally depicted in FIG. 1 (0100) wherein an eye model (0110) ophthalmic optical testing apparatus (OTA) (0111) is substituted for an actual human eye in the testing of a fabricated (0120) intraocular lens (IOL) (or lens under test (LUT)) typically comprising polymeric lens material (PLM) (0121). The fabrication (0120) process typically involves the use of a lens tailoring source (LTS) (0130) comprising a laser source/scanner (0131), laser power supply (0132) and optional microscope objective (0133). The LTS (0130) is typically under control of a computer control system (CCS) (0140) that generally includes a digital computer (0141) executing machine instructions read from a computer readable medium (0142) and receiving overall command direction from a graphical user interface (0143) under direction of a human operator (0144).

The purpose of the ophthalmic optical testing apparatus (OTA) (0111) in this application context is to verify the function of the fabricated lens (0120) and determine if the optical characteristics of the lens in combination with that of the patient's eye characteristics as modeled by the OTA are suitable for the patient prior to actual patient surgery.

Ophthalmic Optical Testing Apparatus Overview

A general overview of the ophthalmic optical testing apparatus (OTA) (0111) in FIG. 1 (0100) is generally depicted in the system block diagram of FIG. 2 (0200) with an assembly view of the various components of the OTA generally depicted in FIG. 3 (0300). The OTA is typically constructed upon a stable planar surface using a base comprising an axial positioning platform (APP) (0210, 0310) that allows rotation about a vertical or horizontal axis of an optical retention framework (ORF) (0220, 0320). The ORF (0220, 0320) is mechanically mated to one or more longitudinal axis positioning platforms (LAP) (0230, 0330,

0240, 0340) referred to herein as the corneal LAP (CLP)

(0230, 0330) and test LAP (0240, 0340) that allow longitudinal adjustment of lenses and other optics along a common longitudinal optical axis (LOA) (0299) pathway.

At least one LAP (0230, 0330) serves to mechanically retain a corneal lens fixture (CLF) (0250, 0350) that comprises corneal lens optics (CLO) (0251, 0351). One or more LAP (0240, 0340) serves to support a test lens fixture (TLF) (0280, 0380) that retains a lens under test fixture (LUF) (0290, 0390). The ILF (0290, 0390) supports retention of one or more intraocular lenses (IOL) or lenses under test (LUT) (0291, 0391) that may be substituted using different removable LUF (0290, 0390) structures within the overall

OTA.

The ORF (0220, 0320) provides for a cassette support tower (CST) (0221, 0321) that has one or more slots that allow a lens cassette fixture (LCF) (0260, 0360) to be retained along the LOA (0299). The LCF incorporates an aperture (0361) along the LOA (0299) that in some embodiments may be adjustable. The LCF (0260, 0360) allows capture of a pupil lens fixture (PLF) (0270, 0370) that contains pinhole or light block device (POL) (0271, 0371) that mimic optical characteristics of the patient's eye. Within the context of the present invention, the CLF (0250, 0350), PLF (0270, 0370), and LUF (0290, 0390) allow replacement of the respective CLO (0251, 0351), PLF (0271,

0371), and LUF (0291, 0391) lens structures to be replaced/substituted with ease thus allowing the overall LOA (0299) pathway to be optically adjusted to mimic the overall characteristics of the patient's eye in conjunction with an IOL (0291, 0391) lens structure under test/evaluation.

Adjustment of the axial/tip/tilt position of the ORF (0220) mounted upon the APP (0210) and relative position of the CLF (0250) via the corneal LAP (CLP) (0230) in conjunction with proper selection of the LCF (0260) / TLF

(0280) / IOL (0281) and adjustment of the related test LAP

(0240) permit adjustment of the optical characteristics of the LOA (0299) to support a variety of pre-surgery patient testing objectives prior to committing to actual patient surgery. One skilled in the art will recognize that the IOL fixture (LUF) (0290, 0390) depicted in FIG. 3 (0300) may be embodied in a variety of forms to allow the positioning and substitution of an intraocular lens (IOL) (0291, 0391) within the LUF (0290, 0390) framework. As such, no additional detail of this fixture is provided herein except as to the additional detail provided in FIG. 65 (6500) - FIG. 80 (8000) which provides detail on a pupil lens fixture having a similar cassette substitution structure. One skilled in the art will no doubt realize that while FIG. 65 (6500) - FIG. 80 (8000) may be used to implement the LUF (0290, 0390), other forms of equivalent function may be substituted without departing from the scope of the claimed invention.

Optical Testing Paper

As generally depicted in FIG. 2 (0200), different optical testing papers (0297) (retina diffusion, thermal, etc.) may optionally be inserted along the LOA to simulate the retinal position and evaluate thermal heat buildup from different procedures. The present invention allows operator training with class II and III laser devices without the need for actual patient participation and also allows for patient-safe validation of heat dissipation algorithms and safety factors by medical device manufacturers. These testing papers are shown by example and are not exhaustive of the testing papers that may be incorporated along the LOA of the present invention.

Additional testing options for the OTA may include safety tests of ophthalmic devices and facilitating safety training and testing for ophthalmologists. Allowing a different retina insert for the OTA with thermal properties matching the testing devices wavelength can permit testing of laser parameters associated with IOL customization and various Class II and Class III devices. The thermal retina inserts may also be used to test and validate Class II and Class III devices in regards of laser safety.

Exemplary Embodiment Detail Views (0400M1600Ϊ

As previously discussed, an assembly view of a preferred exemplary invention embodiment is generally depicted in FIG. 3 (0300). Various assembled views of this preferred exemplary invention embodiment are generally depicted in FIG. 4 (0400) - FIG. 16 (1600).

While the present invention may incorporate a variety of mechanisms for retaining optics within the overall OTA testing framework, many preferred invention embodiments employ an optical retention framework (ORF) as generally depicted in detail in FIG. 17 (1700) - FIG. 32 (3200).

As generally depicted in FIG. 25 (2500) and FIG. 29 (2900), the ORF incorporates a cassette support tower (CST) (2521) perpendicularly attached to a retention framework base (RFB) (2522) having a top framework surface (TFS) (2523) and a bottom framework surface (BFS) (2924). The (CST) (2521) incorporates one or more vertical slots (2525) in which one or more lens cassette fixtures (LCF) may be inserted and retained.

Corneal Lens Fixture (CLR (3300M4800i

While the present invention may incorporate a variety of mechanisms for retaining an optical lens within the OTA testing framework, many preferred invention embodiments employ a corneal lens fixture (CLF) as generally depicted in detail in FIG. 33 (3300) - FIG. 48 (4800). This exemplary CLF is illustrated incorporating a lens retention plate (LRP) (3510) fitted with an exemplary fixed lens (3520) and may incorporate a number of screw retention holes (3730, 3740) that are used to mate the CLF to the optical retention framework (ORF) via a longitudinal axis positioning platform (LAP). The corneal lens can be customized, and different materials can be used, acrylic, silicone, or other materials, to test different materials or customizations.

Test Lens Fixture (TLR (4900)-(6400

While the present invention may incorporate a variety of mechanisms for retaining a test optical lens within the OTA testing framework, many preferred invention embodiments employ a test lens fixture (TLF) as generally depicted in detail in FIG. 49 (4900) - FIG. 64 (6400).

This exemplary ALF is illustrated incorporating means for allowing the lens cassette fixture (LCF) that incorporates an IOL/LUT lens fixture (ILF) or lens under test fixture (LUF) to be placed along the LOA and adjusted via use of the various LAP longitudinal adjustments provided in the system.

Lens Cassette Fixture (LCR / Pupil Lens Fixture (PLR(6500)-

(8000)

While the present invention may incorporate a variety of mechanisms for testing and substituting an optical lens within the OTA testing framework, many preferred invention embodiments employ a lens cassette fixture (LCF) and/or pupil lens fixture (PLF) as generally depicted in detail in FIG. 65 (6500) - FIG. 80 (8000). One skilled in the art will recognize that there are a wide variety of ways in which to implement retention of the pinhole or light block device (POL) within the context of the present invention.

Axial positioning platform (APP) (8100 -(10400

While the present invention may be mounted on a variety of base platforms, many preferred invention embodiments employ an axial positioning platform (APP) as generally depicted in detail in FIG. 81 (8100) - FIG. 104 (10400).

However the axial positioning platform can be mounted vertically, horizontally, or can be used to evaluate tip/tilt positioning issues.

The APP depicted herein is a general purpose vertical axis positioner that employs an axial base platform (ABP) (8110, 9210) supporting an axial support platform (ASP)

(8120, 9220) through a series of mechanical connections that include a manual rotational actuator (MRA) (8130, 9230) that rotates the axial support platform (ASP) (8120, 9220) about the axial base platform (ABP) (8110, 9210) through a commonly connected vertical axis (8560, 9260). Tip (8140,

9240) and tilt (8150, 9250) adjustment controls allow the axial support platform (ASP) (8120) to be tipped/tilted as required about the vertical rotation axis (8560, 9260) connecting the axial base platform (ABP) (8110) and axial support platform (ASP) (8120). FIG. 97 (9700) - FIG. 104
