Abstract
An ophthalmic surgical lens to prevent retinopathy caused by microscopic illumination during cataract or intra-ocular lens surgery. The lens is soft and includes a transparent lens portion placed on a cornea, at least one haptic that extends from the base of the lens portion, and at least one aperture formed by the at least one haptic and the base of the lens portion. The at least one aperture exposes the ocular surface to allow for surgical incisions. The lens portion prevents incisions from being made on the cornea during surgery. The lens also absorbs a patient's corneal refraction so as to prevent the retinopathy.
Claims31
A surgical lens to prevent retinopathy caused by microscope illumination during ophthalmic surgery, which surgical lens is placed on a patient's eye, over the cornea, comprising;
- a transparent lens portion made of a soft material and having a concave surface simulating a human corneal surface, said concave surface to be placed over the cornea;
- at least one haptic that is made of a soft material, extends from the lens portion, and has a surface for facing a human sclera that simulates a human scleral radius;
- and
- at least one aperture formed by the haptic and the lens portion to expose an exterior portion of the ocular surface within an over-all area defined by the lens,
- wherein only said surface of the lens portion and said surface of the at least one haptic contact the eye.
A surgical lens to prevent retinopathy caused by microscope illumination during ophthalmic surgery, which surgical lens is placed on a patient's eye, over the cornea, comprising;
- a transparent lens portion having a concave surface simulating a human corneal surface, said concave surface to be placed over the cornea;
- at least one haptic made of a soft material that extends from the lens portion;
- and
- at least one aperture formed by the haptic and the lens portion to expose an exterior portion of the ocular surface within an over-all area defined by the lens;
- wherein the at least one haptic includes a surface which faces the sclera and simulates a human scleral radius.
A surgical lens for use in a cataract surgery or an intra-ocular lens implant surgery, comprising:
- a transparent lens having a surface to be placed on an exterior surface of an eye, over the cornea, said lens surface having a concave radius between 7 and 10 mm and, a diameter of at least 6 mm, and a lens optical configuration selected from the group of piano-concave, bi-concave, meniscus and prism-concave,
- wherein only said surface of the lens contacts the eye.
A surgical lens, comprising;
- a transparent lens portion made of a soft material and having a surface on a base that is concave to simulate a human corneal surface, said concave surface to be placed on an exterior surface of an eye, over the cornea;
- at least two haptics, each of which is made of a soft material, extends from the base of the lens portion, and has a surface that faces a human sclera and simulates a human scleral radius;
- and
- at least two apertures, each of which is formed between each haptic and the base, wherein each aperture exposes an exterior portion of the ocular surface,
- wherein only said surface of the lens portion and said surface of the at least two haptics contact the eye.
A surgical lens for allowing intra-ocular manipulation of instruments during cataract and intra-ocular lens implant surgeries, which surgical lens portion is placed over a patient's eye cornea, comprising:
- a transparent lens portion made of one of a hard and a soft material, wherein a surface of the lens portion to be placed over the patient's cornea has a concave radius between 7 and 10 mm, a diameter of at least 6 mm, and a lens optical configuration selected from the group of plano-concave, bi-concave, meniscus and prism-concave;
- wherein only said surface of the lens portion contacts the eye.
A surgical lens used to facilitate removal of a cataractous lens or an intra-ocular lens captured in a vitreous cavity in a patient during cataract or intra-ocular lens implant surgery, which surgical lens is placed over the patient's eye cornea, comprising;
- a transparent lens portion made of one of a hard and a soft material, wherein a surface of the lens portion to be placed over the patient's cornea has a concave radius between 7 and 10 mm, a diameter of at least 6 mm, and a lens optical configuration selected from the group of plano-concave, bi-concave, meniscus and prism-concave,
- wherein only said surface of the lens portion contacts the eye.
A surgical lens for use in anterior segment surgery, during an entire surgical procedure, which lens is placed over a patient's eye cornea, comprising:
- a transparent lens portion made of one of a hard and a soft material, wherein a surface of the lens portion to be placed over the patient's cornea has a concave radius between 7 and 10 mm, a diameter of at least 6 mm, and a lens optical configuration selected from the group of plano-concave, bi-concave, meniscus and prism-concave:
- at least one haptic that extends from the lens portion;
- and
- at least one aperture formed by the haptic and the lens portion to expose an exterior portion of the ocular surface providing for surgical incisions, within an over-all area defined by the surgical lens;
- wherein only said surface of the lens portion and the at least one haptic contact the eye.
A surgical lens to prevent retinopathy caused by microscope illumination during ophthalmic surgery, which surgical lens is placed on a patient's eye, over the cornea, comprising;
