Results of IOL exchange and iris repair surgery

The patient from the last blog entry underwent a successful surgery yesterday. The old IOL was found to have a damaged leading (nasal) haptic, and the trailing (temporal) haptic was in the sulcus while the rest of the IOL was in the capsular bag. That accounted for the reason why this IOL was nasally decentered, which in the case of a lens with negative spherical aberration causes coma and degrades the visual quality.

Using viscoelastic on a needle, the capsular bag was opened and the old IOL was carefully dissected out of the capsular bag and into the anterior chamber. The new IOL was placed into the sulcus, and the old IOL was bisected and removed from the eye. The iris defect was then closed using two sutures. Because the iris defect was near the phaco incision, a McCannel suture technique could be used instead of the Siepser technique.
This photo was taken at the end of the surgery and it shows the result: a well-centered IOL of the correct power and a new pupil formed by the iris closure. You can see the temporary hydration of the temporal corneal incision as well as the two paracenteses incisions. After healing and resolution of inflammation, I anticipate that the patient will see very well.
