## Abstract

A luminescent ophthalmic device for administering therapeutic materials, the device having at least one luminescent marker disposed in proximity to a therapeutic agent applicator so as facilitate placement in a treatment position when viewed using transcorneal or transpupillary viewing methods.

## Claims

### Claim 1

A luminescent ophthalmic device for placing a therapeutic agent into a treatment position, the device comprising:
a light transmissive wand;
a non-retractable wand tip connected to the wand, the wand tip including a receptacle disposed within the wand tip, the receptacle configured to hold a therapeutic agent; and
at least two luminescent, reference point markers disposed around the receptacle in the wand tip, the reference point markers discriminating a boundary of the receptacle within the wand tip when viewed through transpupillary viewing methods; the reference point markers activated by visible light or ultra-violet light (UV) having propagated through the light transmissive wand.

### Claim 2 (depends on 1)

The device of claim 1, wherein the at least two luminescent markers include a phosphorescent marker.

### Claim 3 (depends on 2)

The device of claim 2, wherein the phosphorescent marker includes fluorescein or diphenyl oxalate.

### Claim 4 (depends on 1)

The device of claim 1, wherein the light transmissive wand is implemented as a longitudinal, light-transmissive element configured to direct light propagation to the at least two luminescent markers.

### Claim 5 (depends on 4)

The device of claim 4, wherein the longitudinal, light-transmissive element is implemented as the body of the wand itself.

### Claim 6 (depends on 5)

The device of claim 5, wherein the at least two luminescent marker are implemented define a line circumscribing the therapeutic agent when disposed in the cavity.

### Claim 7 (depends on 6)

The device of claim 6, wherein the markers are implemented as a set of pegs integrally attached to an attachable tip forming a cavity floor when attached to the tip.

### Claim 8 (depends on 4)

The device of claim 4, wherein the longitudinal, light-transmissive element is implemented as light pipe embedded in the body of the wand.

### Claim 9 (depends on 8)

The device of claim 8, wherein the markers are implemented as a set of pegs integrally attached to an attachable tip forming a cavity floor when attached to the tip.

### Claim 10 (depends on 1)

The device of claim 1, wherein the wand tip includes at least one embedded light emitting diode configured to direct light onto the at least two luminescent markers.

### Claim 11 (depends on 10)

The device of claim 10, wherein the at least two luminescent markers define a line circumscribing the therapeutic agent when disposed in the cavity.

### Claim 12 (depends on 10)

The device of claim 10, wherein the markers are implemented as a set of pegs integrally attached to an attachable tip forming a cavity floor when attached to the tip.

### Claim 13 (depends on 10)

The device of claim 10, wherein the at least two luminescent markers include phosphorescent markers.
