Why are toric contact lenses more expensive
Toric contact lenses
Due to their special shape, toric contact lenses can compensate for astigmatism. To do this, however, they have to match the individual corneal surface of each eye exactly. Therefore, an adjustment by an experienced contact lens specialist is essential.
What are toric contact lenses?
If the corneal curvature, also known as astigmatism, the surface is unevenly curved. As a result, the cornea breaks the light more strongly in some areas than in other areas. This distorts individual pixels and the person concerned sees out of focus. Toric contact lenses are shaped to resemble the irregular curves of a crooked cornea. This allows toric lenses to compensate for a curvature of the cornea and image points on the retina sharply.
What is the difference between toric and spherical lenses?
The difference between toric and spherical lenses is their shape. Spherical lenses are the most common contact lenses that have a simple round curvature. The shape of toric lenses is more complex because a crooked cornea is not shaped like the cap of a uniformly round sphere.
Therefore, the orientation of toric lenses during insertion also plays an important role. Certain markings on the lens show the wearer how to insert the toric lenses. In addition, certain mechanisms are incorporated so that the lens maintains its orientation. Because slipping of the toric lens has an enormous impact on visual acuity.
When are toric lenses useful?
In the case of slight astigmatism, spherical contact lenses can be sufficient for correction if they are made of dimensionally stable material. Because dimensionally stable lenses float on a tear film that adapts to the curvature of the cornea and thus assumes a toric shape. If the curvature of the cornea is less than 0.5 diopters, the contact lens wearer does not notice any difference between toric and spherical lenses. Stronger Astigmatism on the other hand, only toric contact lenses can compensate satisfactorily. However, there are sometimes serious cases where contact lenses can no longer correct the visual defect.
The choice of toric lenses
Toric contact lenses are made of soft or dimensionally stable material. There is also a choice between daily, monthly and annual lenses. In addition to the astigmatism, a toric lens can also correct nearsightedness or farsightedness. Contact lenses can even be toric and multifocal at the same time. Multifocal contact lenses have integrated zones with different strengths and enable like one Varifocals sharp vision near and far. However, experience is required when wearing multifocal toric contact lenses. Because the contact lens wearer first has to get used to the continuously sharp vision through the multifocal lenses.
The care of toric contact lenses
The care of toric contact lenses is identical to that of ordinary contact lenses and depends on the contact lens material and personal factors. Choosing your care program and learning how to handle your contact lenses are part of any initial fitting with a contact lens expert.
Toric contact lenses - advantages and disadvantages
The advantages of toric contact lenses are their great diversity and the ability to correct severe astigmatism in addition to farsightedness or nearsightedness. This allows people with astigmatism to choose between soft and dimensionally stable contact lenses as well as between different replacement lenses and long-term lenses.
However, the higher price is a disadvantage of toric contact lenses. Further disadvantages can also occur depending on the type of mechanism incorporated that ensures the correct orientation of the toric lens in the eye. For example, some toric lenses take a few minutes to reach their proper position after insertion. It can also happen that the lenses shift minimally from time to time. Other toric lenses, on the other hand, reliably retain their position, but are somewhat thicker and therefore more felt in the eye.
Advantages of toric lenses
- The ability to correct astigmatism at the same time as nearsightedness or farsightedness
- Available as soft contact lenses as well as dimensionally stable contact lenses
Disadvantages of toric lenses
- Higher price
- Thinner toric lenses are more difficult to position and can move minimally in the eye
- Thicker toric lenses can be felt more in the eye
Toric lenses in children
Adjustment by a contact lens specialist is mandatory in any case. They are also available to advise and may be able to assess whether contact lenses are suitable for the child.
Toric lenses for cataract surgery
Toric lenses are also available as so-called Intraocular lensthat replaces its own lens in the eye. At a cataract or grey star the lens of the eye becomes increasingly cloudy until an artificial lens has to replace the lens anyway. Therefore, there is the possibility of using toric lenses Cataract surgery to use. These correct the different refractive power of the cornea afterwards in the eye. Contact lenses to compensate for astigmatism or nearsightedness are usually no longer necessary afterwards, as patients with toric lenses after cataracts describe their experiences. However, reading glasses may still be required.
What is the cost of toric contact lenses?
Due to their special nature, toric contact lenses are somewhat more expensive than conventional lenses. The price also depends on the material and on whether it is daily, monthly or annual lenses. Multifocal toric contact lenses are even more complex and thus justify their higher price. After all, these can compensate for several ametropia and provide a new quality of life, as many wearers of multifocal toric contact lenses describe their experiences with it.
Do health insurances cover the costs for toric lenses?
Health insurance companies usually do not pay for toric contact lenses. Statutory health insurance companies only cover part of the costs if the eyesight is severely impaired or if contact lenses are medically necessary for children. Private health insurances and additional insurances reimburse the costs of the lenses depending on the insurance and tariff. Experience has shown that the costs for interocular toric lenses for cataracts are also not fully reimbursable.
Buy toric contact lenses online?
Toric contact lenses are available online, but as with all contact lenses, customization by a contact lens specialist is essential. With toric lenses, the accuracy of fit is particularly crucial. On the one hand, the three values sphere, cylinder and axis play an important role. If these values are not correct, a satisfactory correction of the visual impairment is not possible. On the other hand, the size and the radius of curvature of the lens as well as the material must also meet personal needs.
Professional advice and adjustments can therefore only be provided by an on-site expert. Only through appropriate follow-up checks is it clear which contact lenses really suit you.
