The femtosecond laser technology that brought new levels of safety, accuracy and predictability to LASIK surgery is also advancing cataract surgery. In our office, we call the procedure Refractive Laser-Assisted Cataract Surgery (ReLACS), but it also is known generally as laser cataract surgery.n traditional cataract surgery, the surgeon creates an opening in the capsule with a small needle and then uses that same needle or a forceps to tear the capsule in a circular fashion. In laser cataract surgery, the anterior capsulotomy is performed with a femtosecond laser.
PZT is the most widely used ferroelectric material in industry as of 2011. It is a hybrid material between ferroelectric lead titanate and anti-ferroelectric lead zirconate, which allows formulas for the material to be engineered closer to one or the other ends of the ferroelectric or anti-ferroelectric spectrum.he ferroelectric effect draws its name from ferromagnetism, which describes permanent magnetic materials based on iron that are found in nature. This is a bit of a misnomer, however, as most ferroelectric materials are not based upon the element iron.
