Femtosecond laser cataract (C33186)

For the laser procedure, the patient lies on the bed, which is rotated into position and the patient’s eye is docked to the laser via the curved patient interface using a ‘soft docking’ approach. Optimal docking is achieved using the intelligent pressure sensors and high resolution OCT imagery. Procedural planning is then performed using the OCT displayed on the graphic user interface, marking the important anatomical landmarks and safety parameters.

Upon accepting the treatment plan, the laser ablation commences, first with the capsulotomy, followed by lens fragmentation. The laser treatment can be viewed as fine gas bubbles on the video display and on the OCT. Notice the cut in the capsule on OCT.  Following the laser treatment, the phaco is performed using some slight alterations to the standard cataract technique. The capsule is gently removed with forceps using a centripetal action. Balanced salt solution is then injected directly into a central fragmentation channel which creates a fluid wave. This both hydrodissects and frees the lens. The technique further assists with lens dismantling following the laser fragmentation. Lens segment by segment removal can then be performed with ease. Following irrigation/aspiration, the IOL is implanted in the routine manner. The accuracy of the laser results in excellent centration and IOL overlap of the capsulotomy.
