LARS is helpful for remembering axis adjustment for a soft toric lens from which perspective?

• A. Doctor's perspective
• B. Patient's perspective
• C. Optometrist's perspective
• D. Manufacturer's perspective

Answer: (A)

Soft toric lenses must sit on the eye with their axis precisely aligned to the prescribed meridian. When a toric lens rotates after fitting, we rotate it in a specific direction to bring the axis back to the intended orientation. LARS is a simple mnemonic that helps clinicians remember how to rotate the lens to move its axis toward the prescribed axis. This adjustment is a clinical maneuver done during the fitting and evaluation by the eye care professional, not something the patient performs or something dictated by manufacturing. So the perspective this mnemonic supports is the doctor’s (or optometrist’s) perspective.
