11 Lens and Cataract
Chapter 12: Preparing for Cataract Surgery in Special Situations
Visualization During Surgery
Corneal laceration and edema can impair the view into the eye such that phacoemulsification cannot be performed safely. Instead, an extracapsular approach may be advisable. Hemorrhage during surgery can further reduce visualization of the anterior segment. The surgeon may use OVDs and inject air intracamerally to occlude vessels and marginalize bleeding. If visualization remains inadequate, the surgeon should close the wound and delay the operation.
