Selecting the right wavefront sensor (aberrometer) is all about striking the right balance. Resolution, dynamic range, and sensitivity are key features that, when adjusted, can affect each other. An aberrometer optimized for a broad spectrum of eye conditions may differ from one that is specialized in addressing severe aberrations.
A high-resolution sensor can be a great option for mild to moderate eye aberrations, providing a lot of detail. However, for more serious corneal conditions, a broader dynamic range can be better, as it handles a wider scope of aberrations.
Choosing a wavefront sensor is like selecting a vehicle for transportation: you wouldn't pick a sports car for off-road adventures just because it excels on the highway. You choose what works best for your needs.
If your goal is to help your patient correct their HOAs to restore their vision through custom wavefront-guided contact lenses, check out the world's first Ovitz xwave aberrometry system purpose-built for correcting HOAs in people with irregular corneas.
