• To simplify intraoperative maneuvers in specific retinal surgical contexts.

Main Methods:

• Development of an illuminated suction needle.
• Integration of the needle with an indirect ophthalmoscope.
• Testing the instrument for air-fluid exchange and subretinal fluid drainage.

Main Results:

• The illuminated suction needle facilitates air-fluid exchange.
• Internal drainage of subretinal fluid is effectively achieved.
• The instrument simplifies intraoperative maneuvers in air-filled phakic eyes.

Conclusions:

• The illuminated suction needle is an effective tool for subretinal fluid management.
