Scleral Lenses: The Contacts for Irregular Astigmatism

If you suffer from irregular astigmatism, you know how challenging it can be to find a solution that provides clear and comfortable vision. Scleral contact lenses are a specialized type of contact lens that can revolutionize your visual experience. These lenses offer a unique design and exceptional benefits for those with irregular astigmatism.
 

Understanding Irregular Astigmatism

Astigmatism is a common refractive error characterized by an irregular shape of the cornea or lens, resulting in blurred or distorted vision. Regular astigmatism occurs when the cornea or lens has a uniform curvature, while irregular astigmatism occurs when the cornea or lens has an uneven curvature. This irregularity causes light to focus on multiple points, leading to distorted vision at all distances. 
 

How Do Scleral Contact Lenses Work?

Scleral lenses are large-diameter gas-permeable contact lenses that vault over the entire cornea and rest on the white part of the eye called the sclera. Unlike traditional contact lenses that sit directly on the cornea, scleral lenses create a tear-filled reservoir between the lens and the cornea. This reservoir acts as a protective cushion, providing clear and comfortable vision. The liquid-filled space also compensates for the irregular shape of the cornea, effectively correcting the refractive error caused by irregular astigmatism.
 

Who Can Benefit From Scleral Contact Lenses?

Scleral contact lenses are a game-changer for individuals with irregular astigmatism. They are particularly beneficial for those who have tried traditional contact lenses but have not achieved satisfactory visual outcomes. Scleral lenses can correct vision in cases of irregular corneal astigmatism resulting from conditions such as keratoconus, post-corneal transplant, or corneal scarring. They can also be effective for patients with irregular astigmatism due to corneal trauma or surgical complications.
 

Scleral lenses can be an excellent solution for individuals with dry eye syndrome. The tear-filled reservoir created by the lens provides constant lubrication to the cornea, relieving dryness and discomfort. This makes scleral lenses a viable option for those who have previously struggled with contact lens intolerance due to dry eyes.
 

Advantages of Wearing Scleral Contact Lenses

Scleral contact lenses offer several advantages over traditional contact lenses, making them an attractive option for individuals with irregular astigmatism. Firstly, the larger size of scleral lenses enhances comfort by minimizing lens awareness. The lens rests on the sclera, avoiding contact with the sensitive cornea, which can lead to discomfort and irritation. This makes scleral lenses suitable for individuals with sensitive eyes.
 

Secondly, the tear reservoir created by scleral lenses provides superior vision quality. The liquid-filled space compensates for the irregular shape of the cornea, correcting the refractive error and offering clear and sharp vision. This is particularly beneficial for individuals with irregular astigmatism, as traditional lenses may not adequately correct their vision.
 

Additionally, the tear layer between the lens and the cornea acts as a barrier, protecting the cornea from outside irritants and allergens. This can be especially advantageous for individuals with allergies or sensitivity to environmental factors.
 

Are Scleral Lenses Right for You?

Scleral contact lenses are a revolutionary solution for individuals with irregular astigmatism. They offer superior vision correction by compensating for the irregular shape of the cornea, providing clear and comfortable vision. Scleral lenses are suitable for those who have not achieved satisfactory visual outcomes with traditional contact lenses and can also benefit individuals with dry eye syndrome. With their unique design and exceptional advantages, scleral lenses are truly the contacts for irregular astigmatism.
