An Adjustable Magnetic Prism Carrier for Strabismus Evaluation

The analysis and quantitation of strabismus can be challenging to examiner and patient, especially when the deviation is large or complex. This can be due to the difficulty of holding multiple prisms in proper alignment and also the difficulty of conducting trials of prisms during real life use for prolonged periods. Most trial frame sets have limits on prism size. We have designed a continuously adjustable, head mounted magnetic prism carrier (MPC) which allows for placement of any strength prism in proper alignment to facilitate strabismus evaluation.
