Effect of Three Types of Specially-Designed Myopia Control Spectacle Lenses on Astigmatism: A Two-Year Result

Key Points

• The study investigates the effect of three types of myopia control spectacle lenses on astigmatism over a two-year period.
• Utilized three specially-designed myopia control spectacle lenses.
• Monitored changes in astigmatism measurements over two years.
• Compared effects across different lens types and their relation to myopia increase.
• Observed a slight increase in refractive astigmatism (<0.50 D) over two years.
• The astigmatism increase was not linked to the type of lens used.
• The increase in astigmatism correlated more with the progression of myopia.
