Are you struggling with vision problems such as keratoconus and astigmatism? Fret not because there are contact lenses specifically designed for people with these issues. Contact lenses can help you achieve better visual clarity and improve your quality of life. So, what do you need to know about contact lens prescription for keratoconus and astigmatism?
Understanding Keratoconus and Astigmatism
Keratoconus is a condition that causes the cornea, the clear, dome-shaped surface of the eye, to thin and bulge outward into a cone shape. This results in blurred and distorted vision, halos around bright lights, and sensitivity to light. Astigmatism, on the other hand, is a common eye condition that causes blurred vision due to an irregularly shaped cornea or lens.
Contact Lenses for Keratoconus
For people with keratoconus, traditional contact lenses may not provide the necessary correction to achieve clear vision. However, specialty contact lenses such as scleral contact lenses and hybrid contact lenses can help. Scleral contact lenses are large, gas-permeable lenses that rest on the sclera (the white part of the eye) and vault over the cornea, creating a smooth optical surface. Hybrid contact lenses have a rigid center that corrects the cornea’s irregularities and a soft outer rim that provides comfort.
Contact Lenses for Astigmatism
If you have astigmatism, toric contact lenses are the go-to option. These lenses have a unique design that allows them to rotate to the correct orientation on the cornea, so the correct axis of the lens aligns with the astigmatism. This ensures accurate vision correction.
The Importance of a Contact Lens Prescription
It’s essential to get a contact lens prescription from a qualified optometrist or ophthalmologist. A proper prescription takes into account the unique shape and needs of your eyes and ensures that you get the correct type and fit of contact lenses. Without a valid prescription, you risk getting ill-fitting lenses that can cause discomfort, eye infections, or even vision loss.
Care and Maintenance of Contact Lenses
Proper care and maintenance of your contact lenses are crucial to ensure their longevity and safety. Always wash your hands thoroughly before handling your contacts, and follow the recommended cleaning regimen for your lenses. This involves using contact lens solution to clean and disinfect the lenses and replacing your lenses as directed by your eye doctor.
Conclusion
Contact lenses can be a game-changer for people with keratoconus and astigmatism. However, it’s crucial to get a proper prescription and follow the recommended care and maintenance guidelines to avoid eye problems. Speak to your eye doctor to see if contact lenses are a good option for you.
