Astigmatism Correction and Contact Lens Selection Guide ๐โจ
โขPosted on September 26 2024
Approximately 45% of people who wear glasses or contact lenses have astigmatism of 0.75D or higher, and around 25% have astigmatism of 1.25D or higher. ๐ค Astigmatism can cause symptoms like decreased vision and eye fatigue, making correction necessary. Depending on the degree of astigmatism and nearsightedness, the need for correction can vary. Therefore, it's crucial to choose the right correction method tailored to the individual's astigmatism level. ๐ง
Correction Methods Based on Astigmatism Level ๐
1. When Astigmatism is 2.5 Diopters or Below
In this case, wearing spherical RGP lenses is the most common option. Aspheric RGP lenses can also be an option, and for those who find wearing RGP lenses difficult, toric soft contact lenses are an alternative. ๐คฉ If astigmatism is 1.0 diopters or below, standard soft contact lenses can provide sufficient correction!
2. When Astigmatism Exceeds 2.5 Diopters
a. Toric Soft Contact Lenses
Toric soft contact lenses can be uncomfortable and may not provide optimal correction. Additionally, they usually need to be custom-made, which increases the price and limits their usage. ๐ก
b. Spherical RGP Lenses
In cases of severe astigmatism, spherical RGP lenses may cause reduced correction due to the curvature of the lens. However, they are easier to prescribe and more affordable than toric RGP lenses. ๐ถ๏ธ If the astigmatism is not too severe, spherical RGP lenses, combined with astigmatism glasses if needed, can be effective.
c. Aspheric RGP Lenses
Aspheric RGP lenses fit the cornea better and provide improved centering compared to spherical RGP lenses. They are especially useful for irregular corneal astigmatism or corneal deformation, though they are more complex to manufacture and more expensive. ๐ฏ
d. Toric RGP Lenses
For severe corneal astigmatism, toric RGP lenses are highly effective. These lenses can be customized for the front and back surfaces, but their complex manufacturing process and high cost make them a more challenging option to prescribe. ๐
The Difference Between Refractive and Corneal Astigmatism ๐ค
1. When There is No Refractive Astigmatism but Significant Corneal Astigmatism
Wearing spherical RGP lenses may reveal residual astigmatism, leading to reduced vision. In this case, spherical soft contact lenses or back-toric RGP lenses can be a solution. ๐๏ธโ๐จ๏ธ
2. When There is Refractive Astigmatism but No Corneal Astigmatism
It is best to use front-toric contact lenses since spherical contact lenses can leave residual astigmatism.
3. When Both Refractive and Corneal Astigmatism are Present but Differ
First, measure residual astigmatism by wearing spherical contact lenses, and then prescribe toric contact lenses for correction. ๐ ๏ธ
