Which solution preservative may damage the surface of a diagnostic GP lens?

Isopropyl alcohol is known to be a harsh solvent that can cause damage to the surface of GP (gas permeable) lenses. When used in lens solutions, isopropyl alcohol can lead to surface degradation, which not only affects the clarity of the lens but can also compromise the lens's oxygen permeability and overall comfort for the wearer.

Diagnostic GP lenses are often made of special polymers that need to be preserved with care. Certain preservatives may alter the lens surface properties or increase surface wettability, but isopropyl alcohol, due to its potent drying and solvent characteristics, can negatively impact the integrity of the lens material.

Understanding the implications of using different preservatives is crucial for maintaining the quality and safety of contact lenses, as well as providing optimal care and recommendations to patients.
