Effect of Center Thickness Variations on the Performance of Rigid Gas Permeable Contact Lenses

Key Points

• The aim is to assess how different center thicknesses affect the performance of rigid gas permeable contact lenses.
• Fitted 20 male myopic individuals with two series of rigid gas permeable lenses.
• Lenses made of the same material but differed in center thickness (0.12 mm vs. 0.15 mm).
• Evaluated mechanical, physiological, and visual performance.
• Thicker lenses (0.15 mm) demonstrated better performance across evaluated categories.
• Performance improvements were noted in mechanical, physiological, and visual aspects.
