Welcome to the Web-Site 
of the International Association for Binocular Fullcorrection!

What is the IVBV and what are its goals?  

The International Association for Binocular Fullcorrection (IVBV) is an association registered in Switzerland, in which members of different professional groups work together on an interdisciplinary basis towards the goal of achieving optimum vision. These include ophthalmologists, optometrists, ophthalmic opticians, orthoptists, speech therapists, school psychologists, teachers and others. 

Unimpaired binocular vision is an important prerequisite for optimum vision. As long ago as the mid-1950s, this awareness led Hans-Joachim Haase to think about new measuring techniques, making him a pioneer in the field of binocular fullcorrection. Today, the methodology developed in this context is known as MKH (Measuring and Correcting Methodology after H.-J. Haase). 

Over a period of more than 40 years, the success of MKH has shown that unimpaired binocular vision mostly can be achieved by prismatic fullcorrection of any existing associated phoria. It is therefore the declared goal of the IVBV to propagate the MKH and to incorporate new scientific knowledge in its ongoing enhancement. 

This goal is pursued not only by means of the annual congresses held by the IVBV, but also by various regional events which anyone interested is cordially invited to attend. 

The IVBV’s aim is to promote the uniform and correct application of the MKH. Therefore the 'Guidelines for the Correction of Associated Heterophoria' can be downloaded for free by clicking here as Adobe PDF-File. If you want to order this document as a print please click here.

To read or print this file, you need the 'Adobe Acrobat Reader'. If it is not yet installed on your system, you can do this by clicking the symbol on the left.

You can find a list of literature about the MKH and other topics related to binocular vision on this website.

So far only one paper can be downloaded as pdf-file.

For any questions or suggestions please feel free to contact the IVBV at their agency. The best way will be an e-mail to IVBVmail@t-online.de.
