Comparison of the regular guillotine-shaped and the constant flow blade (CFB). The regular guillotine-shaped blade (upper portion) completely closes on position C, whereas the CFB maintains the same amount of port opening during the total cutting cycle, while chopping the vitreous at the proximal and distal edge of the blade (position C—lower portion).
