Continuous Curvilinear Capsulorhexis on Grapes

This idea came from Figueira EC et al: The grape: An appropriate model for continuous curvilinear capsulorhexis, J Cataract Refract Surg 2008, 34:1610-1. 
These authors compare the tensile strength of the red globe grape's skin and the tensile strength of the aging human capsule, which are similar; comparatively, the tensile strength of the porcine anterior capsule resembles more to the human infant's capsule.
In the video you will see the procedure performed by one of our residents. The grape's skin is even more fragile than the human's anterior capsule, so you should be very delicate to avoid tearing it off.
Movements with the Utrata forceps are similar to those in live patients: after central perforation and formation of a small triangular flap, follow an imaginary helix centrifugally from the center to the periphery (you may also watch 'Teaching capsulorhexis' at http://icopedia.ophthalmologyblogs.org).
