There are times when it is helpful to perform a posterior capsulorhexis. This is a tricky maneuver because it opens the communication between the posterior chamber and the vitreous cavity. There are techniques that can be used to minimize the risks and increase the surgical control. In this case the posterior capsule is heavily scarred with fibrotic tissue. The posterior capsule is punctured centrally and then a dispersive viscoelastic is gently injected through this opening. The goal is to separate the back surface of the posterior capsule from the anterior hyaloid face of the vitreous. In this case the fibrotic tissue poses a challenge but our guest surgeon does a beautiful job of overcoming that.
