We have both in our program, we use pigs eyes more than the EyeSi but even then we don't use it as often. At the VA our attendings require that the second year residents practice on either of them before we start our cataract surgeries. I like the EyeSi for anti tremor training and the capsulorhexis I guess it makes me feel less anxious. I like the pigs eyes to practice wounds, wound suturing and every once in a while capsulorhexis, we asked for a phaco but it is a two year process to get one of the old phacos from alcon so by then I'll be gone!
