The removal of the central part of the anterior lens capsule during cataract surgery is known as anterior capsulotomy. It gives the surgeon access to the lens inside so that it can be removed. The remaining part of the capsule is left in place and provides a barrier between the anterior and posterior

Nitinol tip can be collapsed sufficiently to pass through an incision of about 2.2 mm, after which it springs back into circular shape inside the anterior chamber. The device is moved into contact with the anterior capsule, held in position

to do capsulotomy. The laser produces a precisely spaced row of adjacent perforations through the capsule, and can produce uniformly circular, accurately centred cuts compared with manual CCC, but the edges are relatively rough and this can reduce tear strength due to stress concentrations, though
280:
Envelope capsulotomy is done by making a linear incision in upper one-third of anterior capsule, after which the nucleus is extracted and cortical matter arpirated. After cataract removal cuts are started at the ends of the incision and the opening for implantation is formed by tearing as in CCC.

bleeding, and when used correctly there is no collateral tissue damage. There is no tearing stress applied to the capsule during the cut, and the tip cuts along the line of contact with the capsule, as guided by the surgeon. The cut edge may not be as strong as the edge produced by manual CCC.

Plasma blade capsulotomy uses plasma technology to make a circular incision through the anterior capsule. The energy destroys the molecular structure, and caused transient microscopic plasma and cavitation bubbles in the tissue. The power output and heating effects are small, it does not cause
