Purpose:
To describe a combination light-pipe, soft-tipped suction needle, and infusion cannula instrument for use in macular translocation surgery.
Methods:
Macular translocation surgery was performed in human cadaver and live rabbit eyes with a combination light-pipe, soft-tipped suction needle, and infusion cannula instrument.
Results:
A combination light-pipe, soft-tipped suction needle, and infusion cannula can be used for macular translocation. This instrument is useful for relocating the retina after a 360 peripheral retinotomy is created. It can also be used for macular translocation with the scleral imbrication technique when superior movement of the fovea is required. When used in combination with another soft-tipped suction needle instrument, this surgical instrument allows precise bimanual placement of the retina with simultaneous infusion of liquid perfluorocarbon for fixating the macula to its new location.
Conclusion:
A combination light-pipe, soft-tipped suction needle, and infusion cannula instrument may be a useful tool for macular translocation surgery.
