How to perform an IC-8® Small Aperture IOL Mid-Point 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 Mid-Point 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 Mid-Point, Red/Green or Maximum Plus refraction to accurately determine the eyes true refraction. Refractions can be more challenging in the IC-8 IOL eye. Because of the extended depth of focus provided by the small aperture, these patients will tolerate a larger range of introduced lenses without experiencing blur. AcuFocus™ has developed a technique termed a “Mid-Point” refraction which provides more consistent results with small aperture technologies. The technique is very similar to the technique we use for Negative Relative Accommodation/ Positive Relative Accommodation or as we typically call it, NRA/PRA in near testing, but it is being done with a distant target. Alternatively, a “red/green” balance test can be used to determine the refractive endpoint. In this video, I will take you through a step-by-step approach for using a Mid-Point refraction technique to determine the refraction of an eye implanted with an IC-8 small aperture IOL.
