title: Inverted U' strategy for short pulsed laser posterior capsulotomy.
abstract: Pit marks and cracks in the axial region of the optic of intraocular implants (IOL) in the pseudophakic eye are a frequent clinical observation and follow Nd:YAG laser posterior capsulotomy procedures. A new technique is presented for carrying out YAG capsulotomy without risking damage to the axial part of the optic. This technique has been used successfully on 200 eyes. It makes use of the fact that an opacified posterior capsule reacts to disruption by retracting. This treatment strategy simply directs this process of retraction to create a 3 mm gap in the axial region without having to treat this area.
