For individuals with astigmatism, the ability to wear contact lenses was once limited. However, advancements in technology have expanded the options available for astigmatic patients. While there may still be a relatively limited number of choices for those with a high amount of astigmatism (considered greater than 3 diopters), advancements in contact lens design have paved the way for custom-order soft lenses, gas permeable lenses, and scleral lenses. These options not only provide the necessary vision correction but also ensure a comfortable fit for the wearer.
Custom Order Soft Contact Lenses: Tailored for Astigmatic Eyes
Custom-order soft contact lenses are a popular choice for individuals with high amounts of astigmatism. These lenses are specially designed to correct astigmatism and provide the wearer with clear vision. Compared to standard soft lenses, custom-order lenses come in a wider range of parameters, allowing for precise correction of higher amounts of astigmatism. Additionally, advancements in lens materials and manufacturing techniques contribute to improved comfort and extended wearability.
When considering custom order soft lenses, it is crucial to consult with an eye care professional who can assess your unique needs and recommend the most suitable lens type and brand for your astigmatism correction.
Gas Permeable Contact Lenses: Sharp Vision and Durability
Gas permeable (GP) contact lenses, also known as rigid gas permeable (RGP) lenses, are another option for individuals with high amounts of astigmatism. These lenses offer distinct advantages over soft lenses, particularly in cases of significant astigmatism. Their rigid nature enables them to correct astigmatism more effectively than soft lenses, providing sharper vision and minimizing blurriness caused by astigmatism.
GP lenses are made of a highly oxygen-permeable material, allowing oxygen to reach the cornea more efficiently. This enhances overall eye health and comfort, even during extended wear. Although they may require an adjustment period for adaptation and initial comfort, many wearers find GP lenses to be a reliable option for astigmatism correction.
Scleral Contact Lenses: Ideal for Severe Astigmatism
Scleral contact lenses are another advanced option for individuals with high amounts of astigmatism. These lenses have gained popularity due to their ability to provide exceptional visual acuity and comfort. Scleral lenses are large, gas-permeable lenses that vault over the cornea and rest on the sclera (the white part of the eye) without touching the corneal surface directly.
Due to their unique design and larger size, scleral lenses provide a stable fit. They effectively correct irregular corneas and astigmatism, making them particularly suitable for individuals with severe astigmatism or other corneal irregularities. Scleral lenses also offer benefits such as improved comfort, increased oxygen permeability, and enhanced tear film stability.
Finding the Right Fit: Consult with an Eye Care Professional
When searching for contact lens options for high amounts of astigmatism, it is crucial to work closely with an experienced eye care professional. They will assess your specific astigmatism prescription, evaluate the curvature of your cornea, and determine which type of lens will provide the best fit and visual correction.
Factors such as corneal shape, level of astigmatism, and overall eye health will guide the choice between custom-order soft lenses, gas-permeable lenses, or scleral lenses.
