Technical Field

The present disclosure relates generally to the field of ophthalmic lenses, and more particularly to electrically active ophthalmic lenses.

Background

The human eye provides vision by transmitting light through a clear outer portion called the cornea, and focusing the image through the crystalline lens onto the retina. The quality of the focused image depends on many factors, including the size and shape of the eye, and the transparency of the cornea and lens. When aging or disease causes the lens to become less transparent, vision deteriorates because of the diminished light that can be transmitted to the retina. This deficiency of the lens of the eye is medically known as a cataract. At present, cataracts are treated by surgically removing the affected lens and replacing it with an artificial intraocular lens ("IOL"). Cataract extraction is the most common operation performed worldwide.

In the natural lens, distance and near vision are provided by a mechanism known as accommodation. The natural lens is contained within the capsular bag and is soft early in life. The capsular bag is suspended from the ciliary muscle by the zonules. Relaxation of the ciliary muscle tensions these zonules and stretches the capsular bag. As a result, the natural lens tends to flatten. The tension of the ciliary muscle relaxes the tension on the zonules, allowing the capsular bag and the natural lens to assume a more rounded shape. In this way, the natural lens can alternately focus on near objects and distant objects.

As the lens ages, it becomes stiffer and less able to change its shape in response to the tightening of the ciliary muscle. In addition, the ciliary muscle loses flexibility and range of motion. This makes it more difficult for the lens to focus on near objects, a medical condition known as presbyopia. Presbyopia affects almost all adults between the ages of 45 and 50.

The improvement to monofocal IOLs is accommodative IOLs, which actually change focus by movement (physical deformation and/or translation within the orbit) when the muscular ciliary body reacts to accommodative stimuli from the brain, similar to the way the natural crystalline lens focuses.

However, the different components of an electrically active or electrically actuated IOL often result in an undesirably large implant that is difficult to implant into an eye through a small incision. Large incisions may lead to surgical complications, such as loss of vision secondary to scarring or trauma to ocular tissue. In addition, electrically active IOLs require a power source to function properly, thereby making the patient susceptible to poor visual quality when the IOL is powered or fails to function due to a system failure.

The apparatus, systems, and methods disclosed herein overcome or more of the deficiencies in the prior art.

Detailed Description

For the purposes of promoting an understanding of the principles of the disclosure, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same.

Embodiments of the present disclosure include accommodating IOL devices configured to correct far and/or near vision and provide good image quality and extended depth of focus ("EDOF") capability even in the event of a system failure, in embodiments, the accommodating IOL devices described herein provide good visual quality by maintaining monofocal visual quality and providing extended depth of focus even without power.

In embodiments, the accommodating IOL devices described herein include electrically active and passive optical components that are separable and distinct portions of the device in contrast to conventional monolithic electrically active accommodating implants, such embodiments may facilitate implantation through a small incision in cases, the accommodating IOL devices described herein may be implanted into the eye to replace a diseased lens (e.g., an opacified natural lens of a cataractous patient) in other cases, the accommodating IOL devices described herein may be implanted in the sulcus 32 (shown in fig. 1) anterior to the natural lens in embodiments, the accommodating IOL devices described herein include a plurality of optical components that may be configured to complement and cooperate with one another when implanted in different regions of the eye to enhance the vision of the patient.

FIG. 1 is a diagram of an eye 10 showing anatomical structures associated with surgical cataract removal and IOL implantation, the eye 10 including an opacified lens 12, an optically clear cornea 14, and an iris 16, a lens capsule or capsular bag 18 located posterior to the iris 16 of the eye 10 containing the opacified lens 12 which is seated between an anterior capsule segment or capsule 20 and a posterior capsule segment or capsule 22, the anterior capsule 20 and the posterior capsule 22 meeting at an equatorial region 23 of the lens capsule 18, the eye 10 further including an anterior chamber 24 located anterior to the iris 16 and a posterior chamber 26 located between the iris 16 and the lens capsule 18.

A common technique for cataract surgery is extracapsular cataract extraction ("ECCE") which involves creating an incision near the outer edge of the cornea 14 and an opening in the anterior capsule 20 (i.e., an anterior capsulotomy) through which the opacified lens 12 is removed. The lens 12 may be removed by various known methods, including phacoemulsification, in which ultrasonic energy is applied to the lens to fragment it into small pieces that are aspirated out of the lens capsule 18 in a timely manner. Thus, the lens capsule 18 remains substantially intact throughout the ECCE process except for the portion of the anterior capsule 20 removed to access the lens 12. The intact posterior capsule 22 provides support for the IOL and acts as a barrier to vitreous humor within the vitreous cavity. After removal of the opacified lens 12, an IOL may be implanted into the lens capsule 18 through an opening in the anterior capsule 20 to restore clarity and refractive function to a healthy lens. Zonule forces exerted by the ciliary body 28 and attached zonules 30 around the periphery of the lens capsule 18 may act on the IOL. The ciliary body 28 and zonules 30 anchor the lens capsule 18 in place and assist in accommodation, which is the process by which the eye 10 changes optical power as the distance of the images changes to maintain a clear focus on the images.

As shown in FIGS. 2 and 3, the accommodating IOL device 100 is shaped as a generally circular disk comprising an active area 105 and a passive area 110. in embodiments, the active area 105 and the passive area 110 comprise a single lens.

In the depicted embodiment, the active region 105 occupies a central region of the IOL device 100, while the inactive region 110 extends to a peripheral region of the IOL device 100. the active region 105 is shaped and configured as a substantially circular component in other embodiments, the active region 105 may have any of a variety of shapes, including, for example, rectangular, oval, elliptical, and square, in embodiments, the active region 105 includes an index of refraction that is different than the index of refraction of the inactive region 110.

Active region 105 may comprise any of a variety of materials that have optical properties that may be changed by electrical control, active region 105 comprises an electrically active element that may provide variable optical power through any adjustable optical technology, including (by way of non-limiting example) a moving lens, liquid crystals, and/or electrowetting, although these variable properties described herein typically include refractive index and optical power, embodiments of the invention may comprise materials having other variable properties such as prismatic power, coloration, and other variable properties.

In embodiments, the inactive region 110 is shaped and configured as a circular ring surrounding the active region 105. in other embodiments, as shown in fig. 3A, the inactive region 110 is shaped and configured as a separate disk adjacent to the active region 105. the inactive region 110 may include a different index of refraction than the index of refraction of the active region 105. the inactive 110 and active 105 regions are formed of any of a variety of biocompatible materials . in contrast to the active region 105, the inactive region 110 is formed of a relatively more flexible material. in embodiments, as shown in fig. 4, the active region 105 may be associated with several other features designed to power and control the active region.although in the depicted embodiment the outer diameter D1a of the active region 105 is shown to be significantly smaller than the outer diameter D2 of the inactive region 110, in other embodiments, the outer diameter D1a of the active region 105 may be sized to be larger relative to the outer diameter D2 of the inactive region 110. in the depicted embodiment, the outer diameter D1 of the active region 105 may be sized to be substantially smaller than the outer diameter D2 of the inactive region 105, however in the exemplary embodiments the active region may be as equal to the outer diameter of the active region 105, in the range of 3637 mm, from the range of the inactive region 11 mm, 366 mm, 3637 mm, and the active region 15 mm, 7 mm, 8mm, 7 mm, 8mm, 7 mm, 8mm, 7.

Accommodating IOL device 100 is designed and optimized such that both active area 105 and inactive area 110 have matching focal points (or matching focal points) to provide a focused image of distant objects on retina 11 for all pupil sizes. When an object is near the eye 10, the optical power of the active region 105 may be adjusted in response to an input signal (e.g., an electrical input signal) to focus the image on the retina 11. This provides accommodation to the patient in a manner similar to a healthy natural lens.

In embodiments, as shown in FIG. 4, the active region 105 may be associated with several other components designed to power and control the active region, by way of non-limiting example, if the active region 105 cannot be powered due to a system failure or a dead battery, the active region 105 is shaped and configured to combine with the passive region 110 to function like a passive or monofocal lens . in an exemplary embodiment, the unpowered active region 105 has the same optical power as the passive region 110. however, due to the thickness and refractive index differences between the two regions, the active region 105 may behave as a passive lens having a different optical power than the passive region 110.
