Details:

A capsular tension ring may not hold the bag in place during phaco if the zonules are especially weak. Surgeons sometimes use iris retractors on the rim of the capsulorhexis in order to manage this problem, but iris retractors aren't designed for this purpose. Since the iris retractor comes in at an angle, the hook is not in the plane of the rim to be supported.

In contrast, CapsuleCare is designed such that the hook is angled to be in the plane of the anterior capsule. As a result, it's easy to get a firm and reliable grip on the rim. Further the tip of the hook is rounded to prevent any accidental damage to the peripheral capsule while placing the hooks in the bag. The round tip also provides with a larger support area per hook thereby reducing the number of hooks required in each surgery. Once the hooks are placed in position to support the capsule, an endocapsular ring can be inserted.

Advantages

• maintains the position of the capsule during phaco
• supports the fornix as well as the capsulorhexis rim, so that the peripheral capsule isn't attracted towards the phaco tip
• avoids the problem of the capsular tension ring trapping cortex
• prevents zonular stress during nuclear rotation
• makes it possible to perform posterior chamber phaco even with dislocated lenses having minimum zonular support.
