Loss of Power with Flexure of Hydrogel Plus Lenses

Key Points

• The study investigates the power change in hydrogel contact lenses when flexed, particularly focusing on low-plus power lenses.
• Theoretical analysis of lens behavior under flexure.
• Clinical testing of hydrogel lenses with varying power levels.
• Confirmed slight power loss in low-plus power hydrogel lenses with flexure.
• No significant change in power observed in low-minus power hydrogel lenses.
