PDF-Tensile properties of soft contact lens materials Ioan

O Box 88 Manchester M601QD UK Abstract The strength of contact lens materials is an important consideration with respect to resistance to damage during lens handling and long term durability and may govern some aspects of ineye lens performance The t. ICL or Implantable Contact Lens as the name suggests is a kind of lens which is implanted into the eye and does not require frequent removal like a normal contact lens This phakic intraocular lens has numerous advantages including its correction of Cara Morris, OD, FAAO.
