Contact Lenses for Astigmatism
Are you suffering from astigmatism? Most people with astigmatism think it is risky to wear contact lenses. There are special contact lenses that are useful in correcting astigmatism. Today's Vision Cinco Ranch is a renowned eye care center in Katy, TX.
Common Contact Lenses for Astigmatism
Toric Contact Lenses
Toric lenses are special soft contact lenses that treat astigmatism. They are made of a permeable silicone hydrogel or conventional hydrogel. However, there are rigid gas permeable toric lenses.
Naturally, the meridians of spherical lenses have the same strength. On the contrary, toric lenses have different powers in their meridians. It is essential to move them vertically and to avoid rotating them. Some toric contact lenses have extra weights at the bottom to stabilize them.
People with astigmatism have different vision needs. It might be tricky to find the right toric contact lenses with the necessary visual acuity and comfort. Besides, fitting them needs special skills compared to fitting standard soft lenses.
Gas Permeable (GP) Lenses
GP lenses do not require a toric design to correct astigmatism. They are sturdy, and they retain a spherical shape when you wear them. The front surface of gas permeable lenses replaces the cornea by refracting light. It corrects astigmatism without rotating the lens. Generally, toric GP lenses are essential in extreme cases of astigmatism.
People who prefer correcting astigmatism with gas permeable lenses have a better vision compared to those wearing standard toric contact lenses. However, their thick profile and rigid nature may require adaptation before you get accustomed to them. Moreover, they require extra time to fit appropriately unlike soft contact lenses as each GP lens has unique parameters.
Hybrid Contact Lenses
Hybrid lenses are appropriate who are not comfortable wearing toric and gas permeable contact lenses. Their central constitutes a sturdy gas porous material with a silicone hydrogel or hydrogel fitting zone. When an optometrist fits them, they effectively correct mild and severe astigmatism. Also, they dramatically improve your visual acuity.
Most hybrid contact lenses have a large diameter and thin edges, which prevents them from dislodging from your eyes. Expertise and adequate time are necessary to fit hybrid lenses. Each client receives custom-made lenses. Their replacement cost is higher than that of soft lenses. However, do not need to replace them regularly.
