to demonstrate a capsulorhexis technique using predominantly shearing forces with a cystotome on a virtual reality simulator and on a human eye .
our technique involves creating the initial anterior capsular tear with a cystotome to raise a flap .
the cystotome tip is tilted horizontally and is engaged on the flap near the leading edge of the tear .
the loose flap is constantly swept towards the centre so that it does not obscure the view on the tearing edge .
re - engage the needle to the tearing edge frequently to create a suitably sized continuous curvilinear capsulorhexis .
our technique has the advantage of reducing corneal wound distortion and subsequent anterior chamber collapse .
the capsulorhexis flap is moved away from the tear leading edge allowing better visualisation of the direction of tear .
this technique offers superior control of the capsulorhexis by allowing the surgeon to change the direction of the tear to achieve the desired capsulorhexis size .

 purpose : to demonstrate a capsulorhexis technique using predominantly shearing forces with a cystotome on a virtual reality simulator and on a human eye.method:our technique involves creating the initial anterior capsular tear with a cystotome to raise a flap . 
 the flap left unfolded on the lens surface . 
 the cystotome tip is tilted horizontally and is engaged on the flap near the leading edge of the tear . 
 the cystotome is moved in a circular fashion to direct the vector forces . 
 the loose flap is constantly swept towards the centre so that it does not obscure the view on the tearing edge.results:our technique has the advantage of reducing corneal wound distortion and subsequent anterior chamber collapse . 
 the capsulorhexis flap is moved away from the tear leading edge allowing better visualisation of the direction of tear . 
 this technique offers superior control of the capsulorhexis by allowing the surgeon to change the direction of the tear to achieve the desired capsulorhexis size.conclusions:the eyesi surgical simulator is a realistic training platform for surgeons to practice complex capsulorhexis techniques . 
 the shearing forces technique is a suitable alternative and in some cases a far better technique in achieving the desired capsulorhexis .
