Abbott Park, IL-A new one-piece IOL (Tecnis Toric 1-Piece IOL, Abbott Medical Optics) has been introduced for use in Europe in patients with cataracts. Unlike conventional IOLs, the new implant can correct pre-existing corneal astigmatism.

Features of the new lens, according to the company:
• Wavefront-designed aspheric and toric optic technologies are combined on a hydrophobic acrylic platform that allows for the transmission of blue light for optimal scotopic vision.
• Spherical aberration essentially is reduced to zero to allow for sharper vision.
• Chromatic aberration is reduced to permit better image quality.
• The haptic (Tri-Fix 3-Point Fixation) is designed to allow for excellent stability and centration.
• The frosted optic edge is designed to reduce potential edge glare effects.
• Practitioners can use an online calculator to determine which model to use in a particular patient to achieve optical surgical outcome (www.TecnisToricCalc.com).
