Abstract

An eye surgery method includes incising a cornea of an eye using a blade portion of a surgical cannulated blade instrument to create an opening in the cornea, injecting injectable into an anterior chamber of the eye through the opening by a lumen of the surgical cannulated blade, and stabilizing the eye by engaging an increasing diameter portion of the surgical cannulated blade with the opening.

Claims

exact text as granted — not AI-modified
1 . An eye surgery method comprising:
 incising a cornea of an eye using a blade portion of a surgical cannulated blade instrument to create an opening in the cornea;   injecting injectable into an anterior chamber of the eye through the opening by a lumen of the surgical cannulated blade; and   stabilizing the eye by engaging an increasing diameter portion of the surgical cannulated blade with the opening.   
     
     
         2 . The eye surgery method of  claim 1 , wherein the injectable comprises viscoelastic. 
     
     
         3 . The eye surgery method of  claim 1 , wherein the injectable comprises lidocaine. 
     
     
         4 . The eye surgery method of  claim 1 , further comprising venting aqueous fluid from the anterior chamber through an indent in the increasing diameter portion. 
     
     
         5 . The eye surgery method of  claim 1 , further comprising, after stabilizing the eye, creating a main incision in the cornea by a main blade. 
     
     
         6 . An eye surgery method comprising:
 incising a cornea of an eye to create an opening in the cornea;   injecting injectable into an anterior chamber of the eye through the opening by a lumen of a surgical cannulated instrument; and   stabilizing the eye by engaging an increasing diameter portion of the surgical cannulated instrument with the opening.   
     
     
         7 . The eye surgery method of  claim 6 , wherein the injectable comprises viscoelastic. 
     
     
         8 . The eye surgery method of  claim 6 , wherein the injectable comprises lidocaine. 
     
     
         9 . The eye surgery method of  claim 6 , further comprising venting aqueous fluid from the anterior chamber through an indent in the increasing diameter portion. 
     
     
         10 . The eye surgery method of  claim 6 , further comprising, after stabilizing the eye, creating a main incision in the cornea.
