If a lens shows edge lift or decentration during wear, what is the most likely clinical action?

• A. Stop using lenses permanently
• B. Reassess and adjust the lens fit parameters.
• C. Switch to a different brand without assessment
• D. Keep the same parameters if discomfort occurs

Answer: (B)

When a lens shows edge lift or decentration, the fit isn’t matching the eye’s shape. That signals the lens parameters aren’t right for centering and comfortable wear. The best clinical action is to reassess and adjust the fit parameters—typically the base curve (try a steeper or flatter curve) and/or the overall diameter, and sometimes the edge design or material. The aim is a centered lens with even edge alignment, proper tear exchange, and stable vision without lid-induced irritation. Start by reviewing keratometry/topography and the current lens parameters, then trial lenses with a different base curve or diameter to find a better fit. If discomfort or instability continues, don’t keep the same settings or switch brands without re-fitting and assessment.
