## Abstract

Systems, apparatuses, and methods of and for an ophthalmic illuminated infusion line are provided. An example ophthalmic illuminated infusion line may include an infusion arrangement having a first flexible elongate member and a flow tube. The first flexible elongate member may have a lumen configured to deliver a fluid to an eye of a patient during a surgical procedure. The flow tube may be sized to penetrate the eye of the patient and deliver the fluid to an interior of an eye to maintain intraocular pressure during a surgical procedure. The ophthalmic illuminated infusion line may also include an optical fiber coupled to the infusion arrangement and configured to penetrate the eye of the patient with the flow tube and transmit light to illuminate the interior of the eye during the surgical procedure at the same time that the flow tube delivers the fluid to the interior of the eye.

## Claims

### Claim 1

An ophthalmic surgical system, comprising:
a light source;
a fluid source;
an illuminated infusion line comprising:
an infusion arrangement comprising:
a first flexible elongate tube defining a first lumen;
a second flexible elongate tube defining a second lumen; and
a flow tube coupled to a distal end of the first flexible elongate tube, the flow tube defining a third lumen and comprising a groove on an exterior surface thereof, the first lumen and the third lumen in fluid communication with the fluid source and configured to deliver a fluid from the fluid source to an interior of an eye of a patient during a surgical procedure, and the flow tube being sized to penetrate the eye of the patient and deliver the fluid to the interior of the eye; and
an optical fiber comprising:
a proximal portion disposed in the second lumen of the second elongate tube; and
a distal portion received within the groove of the flow tube,
the optical fiber being in optical communication with the light source and coupled to the infusion arrangement, the optical fiber being configured to transmit light from the light source to illuminate the interior of the eye during the surgical procedure.

### Claim 2 (depends on 1)

The system of claim 1, wherein at least one of the light source and the fluid source is integrated into a surgical console.

### Claim 3 (depends on 1)

The system of claim 1, wherein the light source is configured to transmit at least one of laser light, white light, red light, blue light, green light, visible light, near infrared light, or infrared light.
