![]() If a larger rhexis is created, it leaves less shelf for sulcus IOL placement if one becomes necessary later in the case. The vector force applied while ripping will indirectly pull on the zonules in the opposite direction.Īdditionally, the size and shape of the rhexis are not always consistent, especially when the capsular bag is loose. Traditional surgery requires manual pulling on the anterior capsule to perform the capsulorhexis. There are many aspects of nucleus removal in traditional cataract surgery that can put stress on the capsular bag and contribute to progressive weakening of the zonules. The laser lessens some of these worries by allowing us to reduce stress on the capsular-zonular complex. In cases such as these, zonular dehiscence can complicate surgery and require a vitrectomy, sewn IOL, or capsular tension ring. Laser cataract surgery technology may ease the surgeon’s anxiety in cases in which there is heightened concern about the integrity of the capsular bag, such as in patients with a history of trauma or previous surgery, pseudoexfoliation, or specific medical conditions.
