"Sometimes rotation of a misaligned ICL can be delicate. Initial placement of ICL usually is done with a rounded spatula “tire-tooling” under an iris. Removal of and ICL usually requires to get a push-pull or some hook under ICL and lift it without touching capsule. 


20 years ago ...I designed a suction cannula that can literally fixate a suction hold on any part of an entire ICL and place it, manipulate it or remove it with no pressure on capsule or iris. Neat little thing. Never seen another one so maybe it’s one of a kind... this one lasted me 20 years...." -Charles Williamson, MD
