A proprietary surgery system brings to laser vision correction surgeons the benefits of expertise in both femtosecond and excimer laser technology.
Chicago-A proprietary surgery system (Technolas Perfect Vision GmbH [TPV]) brings to laser vision correction surgeons the benefits of expertise in both femtosecond and excimer laser technology, said Stephen G. Slade, MD, during refractive surgery subspecialty day at the annual meeting of the American Academy of Ophthalmology.
The TPV system comprises the femtosecond laser workstation (Technolas 520F), a diagnostic workstation (Zyoptix) including the Orbscan IIz topographer and Zywave wavefront aberrometer, the excimer laser workstation (Technolas 217P in Europe and Asia; Technolas 217 in the United States), and a proprietary mechanical microkeratome (Hansatome).
The femtosecond laser features a curved patient interface that does not applanate the cornea and so maintains high surface quality while causing less IOP increase during the procedure. Recent updates include new centration software, a new laser head, and an 80 Hz repetition rate. Combined, these features allow for faster flap creation with improved outcomes accuracy and smoother beds, Dr. Slade said.
