How to perform an IC-8® Small Aperture IOL Red/Green Balance Refraction? | Corina van de Pol, OD,PhD

Corina van de Pol, OD, PhD | Assistant Professor at the Southern California School of Optometry teaches eye care providers how to do a proper Red/Green Balance Refraction Procedure for a patient with a IC-8® Small Aperture IOL. The IC-8 IOL uses a small aperture to extend clear focus across a continuous range of around 3.00 D.  Due to this unique method of action, current automated refraction devices may return unreliable results as the IC-8 IOL has no specific focal point.  So, it is important to use a technique such as Red/Green, Mid-Point or Maximum Plus Refraction to accurately determine the eyes’ true refraction.   In this video, I will take you through a step-by-step approach for using a Red/Green balance refraction procedure to determine the endpoint refraction of an eye implanted with an IC-8 small aperture IOL.   A red/green balance technique may be used to find the Mid-Point balance refraction and is done after determination of a patient’s manifest spherical and cylinder refraction and confirming their best acuity. The purpose of this procedure is to determine the correcting spherical lens power in the IC-8 IOL eye. This procedure makes use of the chromatic aberration properties of the eye, which results in shorter green wavelengths being focused in front of the longer red wavelengths.
