OPD Scan III Refractive Power & Corneal Analyzer

Marco OPD Scan III Fall Creek, TXAt our Fall Creek, TX office, we use the OPD-Scan III from Marco. This remarkable wavefront device uses the most advanced technologies available to help us better evaluate your unique vision needs. It gives us the ability to measure and diagnose your vision much more thoroughly than has ever been possible before by filling your optical path with more diagnostic light rays that catch any imperfections that exist.

Better Eye Exams at TSO Fall Creek

Using the data gathered from the OPD-Scan III, we can make recommendations to help you see more clearly based on a truly complete exam. In fact, the wavefront system makes the entire exam procedure faster and more comfortable for you.

We feel it’s our obligation to offer the best available care to our patients. Our job is to make your vision as close to perfect as we can, and the OPD-Scan III helps us do the job.

Marco automated technologies communicate with each other through ‘Marco Connect’ SW and/or Smart card data transfer. Combined diagnostic exam data is then seamlessly integrated to all leading EMR systems.

Advanced Vision Care

OPD Scan Refractive Power & Corneal AnalyzerOur goal is to achieve superior understanding of your full visual pathway. Traditional refractions can miss small imperfections along your optical path through which light travels. The OPD-Scan III from Marco better simulates real life vision by filling your optical path with more diagnostic light rays that catch any imperfections that exist.

We are now equipped with far more information for the best diagnostic understanding. For the first time, we can see what YOU see – during the day and at night.

We can rapidly see if your vision can be corrected to 20/20, if so – what would be required, and if not – exactly why not. The result is the best possible prescription eyeglasses and contact lenses for your lifestyle.
