Cionni Rings
$649.00 $487.00
These ultra-low profile fixation rings, due to the reversed-bevel, provide better clearance in the periphery, and are easier to instrument the eye. The larger 12.75-mm internal diameter enhances visualization of the surgical limbus whereas the conventional 16-mm outside diameter is preserved.
The enumerated outside Mendez pattern allows orientation to the primary or steep corneal meridian. The inside pattern functions as a symbolic AK guide with arrows at 45 degrees, diamonds at 90 degrees and dots at all other 10 degree increments. This breaks the field into easily distinguished quadrants; the diamonds form cardinal references while the arrows break the quadrants into halves, making it easy to determine arc length and orientation.
All modern globe fixation rings have their origins based upon designs by Spencer P. Thornton, MD.

Description
All enumerated Mastel fixation rings are manufactured with aerospace titanium alloys. We feature welded construction and unique metallurgical surface treatments. These include ceramic plasma vapor deposition and laser etching of the textured finishes providing minimal glare, exceptional contrast sensitivity and a lifetime finish.
