The process evaluates an individual’s ocular health and visual requirements to determine the most suitable type of corrective device. This assessment incorporates a comprehensive eye examination, precise corneal measurements, and evaluation of tear film quality. A sample lens may be placed on the eye to assess fit, movement, and comfort.
Proper evaluation is essential for ensuring comfortable wear, optimal vision correction, and minimizing the risk of complications such as corneal abrasions, infections, or allergic reactions. Historically, these assessments were less precise, relying primarily on subjective feedback from the patient. Modern techniques utilize advanced instrumentation to objectively quantify corneal topography and tear film dynamics, leading to more personalized and successful outcomes.
