Abstract

A vitreous cutter sleeve is disclosed herein. The vitreous cutter sleeve includes an elongate tubular body with a peripheral sidewall and a central passageway disposed through the elongate tubular body, the central passageway of the elongate tubular body configured to receive a vitreous cutter therein, at least a portion of the elongate tubular body being formed from a material that is transparent to visible light, the material being further configured to conduct at least one of infrared radiation, radiofrequency radiation, and an electrical current; and an illumination device operatively coupled to the elongate tubular body such that the illumination device is capable of providing illumination to an inside portion of an eye through at least a portion of the peripheral sidewall of the elongate tubular body. A vitreous cutter system that includes a vitreous cutter and a vitreous cutter sleeve is also disclosed herein.

7. The vitreous cutter sleeve according to claim 6, wherein each of said plurality of opaque band portions are spaced apart from one another by a substantially constant distance such that said plurality of opaque bands portions and said plurality of transparent band portions are capable of being used to determine a depth of insertion of said vitreous cutter sleeve into tissue of said eye.

8. The vitreous cutter sleeve according to claim 6, wherein said plurality of opaque band portions of said elongate tubular body are formed by coating said peripheral sidewall of said elongate tubular body with a black material.

9. The vitreous cutter sleeve according to claim 1, wherein said elongate tubular body comprises an opaque coating from said first end to an exposed tip at said second end so as to enable said exposed tip to function as a localized light source.

10. The vitreous cutter sleeve according to claim 1, wherein said material is transparent to visible light from 400-800 nm, and wherein said material comprises one of:

(i) metal glass, (ii) amorphous glass, (iii) palladium alloy, (iv) zirconium alloy, and (v) aluminum nitryloxyde.

11. The vitreous cutter sleeve according to claim 1, wherein said elongate tubular body comprises insulation from said first end to an exposed tip at said second end so as to enable said exposed tip to function as a localized cauterizer.

12. A vitreous cutter sleeve, comprising:

an elongate tubular body having a first end and a second end disposed opposite to said first end, said elongate tubular body including a peripheral sidewall and a central passageway disposed through said elongate tubular body, said central passageway of said elongate tubular body configured to receive a vitreous cutter therein, at least a portion of said elongate tubular body being formed from a material that is transparent to visible light, said material being further configured to conduct at least one of infrared radiation, radiofrequency radiation, and an electrical current, said first end of said elongate tubular body comprising a flared end portion configured to prevent said vitreous cutter sleeve from entering too deep into said eye, and said second end of said elongate tubular body comprising a pointed tip configured to cut through tissue of said eye; and
