An instrument for initiating an intralamellar channel at a desired depth between the lamellae of the cornea within an incision in the cornea of an eye during a procedure for altering the radius of curvature of the cornea of an eye, said instrument comprising: a handle portion; a central portion, coupled to said handle portion at a position generally coaxial with said handle portion; and an end portion, coupled to said central portion at an acute angle to the central axis of said central portion; whereby when said end portion is inserted into the incision in the cornea until it reaches the bottom of the incision, and said handle portion is rotated, said end portion separates the lamellae of the cornea to form a channel.
L'invention concerne un instrument permettant d'amorcer un canal intralamellaire à une profondeur désirée entre les lamelles de la cornée au sein d'une incision pratiquée dans cette dernière lors d'une intervention destinée à modifier le rayon de courbure de la cornée d'un oeil. Cet instrument comporte une partie manche; une partie central couplée à ladite partie manche au niveau d'une position généralement coaxiale avec cette dernière; et une partie terminale couplée à ladite partie centrale en formant un angle aigu avec l'axe central de cette dernière; ainsi, lorsque ladite partie terminale est insérée dans l'incision de la cornée jusqu'à ce qu'elle touche le fond de cette incision, et que ladite partie manche est mise en rotation, ladite partie terminale sépare les lamelles de la cornée pour former un canal.
