## Abstract

A surgical guide comprising a contact lens comprising a body on which is disposed a reticule, the reticule may be used to guide a surgeon operating on an eye on which the contact lens is located is disclosed. Also disclosed is a surgical method, the method comprising using a reticule on a contact lens to guide a surgical procedure performed on an eye to thereby perform the surgical method. The reticule may comprise one or more concentric circle or concentric shape and/or a set of lines. The reticule may also comprise one or more meridian and/or one or more parallel. The reticule may further comprise one or more net or grid.

## Claims

### Claim 1

A surgical guide comprising:
a conventional contact lens comprised of material used in a conventional contact lens and comprising a body, an external surface and an internal surface, wherein in position on an eye, the inner surface contacts the eye and the external surface is exposed, a reticule disposed on the body, whereby the reticule is used to guide a surgeon operating within the eye on which the contact lens is located;
whereby there is a reduced or no parallax error; and
wherein the contact lens will move with the eye and orient position relative to the eye to compensate for any voluntary or involuntary motion of the patient.

### Claim 2 (depends on 1)

The surgical guide of claim 1, wherein the reticule is comprised on a surface of the contact lens.

### Claim 3 (depends on 1)

The surgical guide of claim 1, wherein the reticule comprises one or more meridians.

### Claim 4 (depends on 1)

The surgical guide of claim 1, wherein the reticule comprises one or more parallels.

### Claim 5 (depends on 1)

The surgical guide of claim 1, wherein the reticule comprises a plurality of circles, squares, rectangles or any other shapes.

### Claim 6 (depends on 1)

The surgical guide of claim 1, wherein the reticule comprises one or more duplex cross-hairs, wherein one or more bar of each of a respective duplex cross-hair is thick on the perimeter and thins out in the middle or in an area of interest.

### Claim 7 (depends on 1)

The surgical guide of claim 1, wherein the reticule comprises two or more concentric shapes.

### Claim 8 (depends on 1)

The surgical guide of claim 1, wherein the reticule comprises one or more region of different scale.

### Claim 9 (depends on 1)

The surgical guide of claim 1, wherein the reticule is customised to an individual eye and wherein the reticule allows ready location of one or more target areas in the individual eye.

### Claim 10

A surgical method, the method comprising:
using a reticule on a conventional contact lens comprised of material used in a conventional contact lens, the conventional lens comprising a body, an external surface and an inner surface, wherein in position on an eye, the inner surface contacts the eye and the external surface is exposed, the reticule disposed on the body, whereby the reticule is used to guide a surgeon operating on the eye on which the contact lens is located;
whereby there is a reduced or no parallax error;
wherein the contact lens will move with the eye and orient position relative to the eye to compensate for any voluntary or involuntary motion of the patient;
the conventional contact lens being used to guide a surgical procedure performed within the eye to thereby perform the surgical method.

### Claim 11 (depends on 10)

The method of claim 10, further comprising the step of placing the contact lens onto the eye.

### Claim 12 (depends on 10)

The method of claim 10, further comprising removing the contact lens.

### Claim 13 (depends on 10)

The method of claim 10, wherein the reticule is comprised on a surface of the contact lens.

### Claim 14 (depends on 10)

The method of claim 10, wherein the reticule comprises one or more meridians.

### Claim 15 (depends on 14)

The method of claim 14, wherein the reticule comprises one or more parallels.

### Claim 16 (depends on 10)

The method of claim 10, wherein the reticule comprises one or more duplex cross-hairs, wherein one or more bar of each of a respective duplex cross-hair is thick on the perimeter and thins out in the middle or in an area of interest.

### Claim 17 (depends on 10)

The method of claim 10, wherein the reticule comprises two or more concentric shapes.

### Claim 18 (depends on 10)

The method of claim 10, wherein the reticule comprises one or more region of different scale.

### Claim 19 (depends on 10)

The method of claim 10, wherein a surgeon is operating within the eye.

### Claim 20 (depends on 10)

The method of claim 10, wherein the conventional contact lens material comprises at least one of hydroxymethylmethacrylate, silicone hydrogel polymers, silicone-acrylates, fluoro-silicone-acrylates, and polymethylacrylate, or combinations thereof.

### Claim 21 (depends on 1)

The surgical guide of claim 1, wherein the conventional contact lens material comprises at least one of hydroxymethylmethacrylate, silicone hydrogel polymers, silicone-acrylates, fluoro-silicone-acrylates, and polymethylacrylate, or combinations thereof.

### Claim 22 (depends on 1)

The surgical guide of claim 1, wherein when the contact lens does move relative to the eye, the contact lens rapidly adopts the previous position without any difficulty, or can be repositioned by the surgeon.

### Claim 23 (depends on 10)

The method of claim 10, wherein when the contact lens does move relative to the eye, the contact lens rapidly adopts the previous position without any difficulty, or can be repositioned by the surgeon.
