Contact Lens Material Receives Expanded Indication

Contact Lens Material Receives Expanded Indication

The American Food and Drug Administration has granted Menicon Z (also referred to as tisilfocon A), a gas permeable contact lenses material manufactured by Menicon Co., ltd. an expanded indication for the management of conditions associated with irregular corneas (in non-diseased eyes). The conditions for which Menicon Z is now indicated include pellucid marginal degeneration, post penetrating keratoplasty, keratoconus, post radial keratotomy and post LASIK surgery.

The new indication means that Menicon Z is a hyper-oxygen delivery (Dk 163) material suitable for the treatment of patients with irregular corneas.

At the moment, the material is available to authorised manufacturers in standard sized blanks, but Menicon is planning to release a large-diameter blank (16.5 mm) for sale to authorised laboratories within the next few weeks.

The information constitutes great news for all patients who have eye problems connected with the irregular shape of their corneas, as it means new contact lenses designed to treat their conditions should be available on the market  soon.
