| titleOfInvention | Laser assisted cataract surgery |
| abstract | Laser assisted cataract surgery methods and devices utilize one or more treatment laser beams to create a shaped opening in the anterior lens capsule of the eye when performing a capsulorrhexis procedure. A light absorbing agent may be applied to the anterior lens capsule to facilitate laser thermal separation of tissue along a treatment beam path on the lens capsule. Relative or absolute reflectance from the eye, and optionally from a surgical contact lens, may be measured to confirm and optionally quantify the presence of the light absorbing agent, before the treatment beam is applied. Such measurements may be used to determine that sufficient light absorbing agent is present in the lens capsule so that transmission of the treatment beam through the capsule will be below a predetermined threshold deemed safe for the retina and other interior portions of the eye, and may also be used to determine that sufficient light absorbing agent is present to result in complete laser thermal separation of the anterior capsule along the treatment beam path. Visualization patterns produced with one or more target laser beams may be projected onto the lens capsule tissue to aid in the capsulorrhexis procedure. In addition or alternatively, virtual visualization patterns may presented on a display integrated with a laser assisted cataract surgery device to aid in the procedure. The visual axis of the eye may be determined, during surgery for example, with a laser beam on which the patient is fixated. The orientation of a toric IOL may be assessed during or after placement by observing the reflection from the back of the eye of a laser beam on which the patient is fixated. The devices disclosed herein may be attached to or integrated with microscopes. |
