During my initial practice I treated a pilot who passed standard vision tests year after year, but he actually was affected by subtle night glare. His refraction appeared normal, but wavefront analysis showed higher order aberrations that a standard exam would not capture. He never realized his corneas were scattering light in a way that could impair his safety at night boarding. That experience changed my practice overall, because it demonstrated that standard testing can only show pieces of the complete picture, and advanced imaging can identify what is ultimately holding back visual function. After that particular case, I now integrate wavefront-guided diagnostics even for patients that present with seemingly perfect 20/20 visual acuity. Less than 5 percent of practices use this technology on a regular basis, yet it can identify micro-irregularities that would have gone undetected on a lesser slit lamp or refraction. Patients make a strong connection to their symptoms when they see a color map and visuals, and confidence is built when surgical planning is based on something more than routine charts.
