System enhancements may put surgery times closer to standard phaco fordense cataract

Salt Lake City-The Photon Laser and Phaco Workstation (Paradigm Medical Industries, Salt Lake City) lets surgeons use either laser or ultrasound to remove a cataract, with the ability of switching back and forth between the two modalities.

Athens, Greece-A novel technique can remove any type of cataract through two small paracenteses, using almost half the energy necessary in traditional phacoemulsification techniques.

Surgical maneuvers used to treat pseudotumor cerebri include some formof shunt procedure, such as a lumboperitoneal shunt, a ventriculoperitonealshunt, or optic nerve sheath decompression (ONSD). Shunting procedures areultimately designed to divert the cerebrospinal fluid (CSF) that is underpressure away from the neuro-ocular junction, where hydrodynamic forcescompress ganglion cells and their blood supply, leading to injury and/ordeath of these cells.

Although emergency room physicians and general plastic surgeons may sometimes feel comfortable repairing simple eyelid lacerations, any laceration in the medial portion of the eyelid almost always results in an ophthalmology consult to evaluate for a canalicular laceration.
