Average Thickness of a Hydrogel Lens for Gas Transmissibility Calculations

Key Points

• The aim is to calculate the average thickness of hydrogel lenses to improve oxygen transmissibility assessments.
• Discussion of existing equations and their deficiencies
• Presentation of a new equation for average thickness calculation
• Analysis of thickness variation based on parameters like power, chord radius, and water content.
• Findings indicate significant underestimation of thickness variation effects in higher powered lenses
• Average thickness calculations change with varying parameters such as power and water content.
• Results highlight that chord radius also plays a crucial role in thickness variation.
