A system and method is disclosed for making incisions in the sclera (102) of an eye (100) to form a scleral pocket (120) to receive a scleral prosthesis (200). The system and method comprises a surgical tool (1100) comprising a surgical blade (1140) for making incisions in the sclera (102) of an eye (100). When a surgeon places the surgical blade (1140) on the sclera (102) of the eye (100) a pressure sensor (2560) in the surgical tool (1100) determines whether there is sufficient pressure between the surgical tool (1100) and the sclera (102) of the eye (300) for the surgical tool (1100) to operate properly. The surgeon activates the surgical tool (1100) to cause the surgical blade (1140) to advance through the sclera (102) to form an incision having dimensions to receive a scleral prosthesis (200). When the incision is complete the surgical blade (1140) is rotated back out of the incision. The incision has the exact dimensions to receive a scleral prosthesis (200).

L'invention concerne un système et un procédé permettant de faire des incision dans la sclérotique (102) d'un oeil (100) afin de former une poche (120) sclérale pouvant recevoir une prothèse (200) sclérale. Ce système et ce procédé font appel à un instrument (1100) chirurgical comprenant une lame (1140) chirurgicale qui permet de pratiquer des incisions dans la sclérotique (102) d'un oeil (100). Lorsque le chirurgien place la lame (1140) sur la sclérotique (102) de l'oeil (100), un capteur (2560) de pression installé dans l'instrument (1100) chirurgical détermine si la pression entre l'instrument (1100) chirurgical et la sclérotique (102) de l'oeil (300) est suffisante pour assurer une bonne opération de l'instrument (1100). Le chirurgien active l'instrument (1100) de manière à faire avancer la lame (1140) à travers la sclérotique (102) et à former une incision présentant des dimensions permettant l'insertion d'une prothèse (200) sclérale. Lorsque l'incision est terminée, la lame (1140) chirurgicale est extraite de l'incision par un mouvement pivotant vers l'arrière. L'incision présente les dimensions exactes permettant l'insertion d'une prothèse (200) sclérale.
