Can Toric Contact Lenses Correct Severe Astigmatism? What to Do If You Have High Cylinder Power

-

 Astigmatism is a common refractive error that causes blurred or distorted vision due to an irregularly shaped cornea or lens. For many people with mild to moderate astigmatism, toric contact lens provide an effective solution for clear, comfortable vision. But what happens when your astigmatism is severe? Can toric lenses still correct high cylinder power, or are there better alternatives?

If you’ve been diagnosed with high astigmatism, often defined as cylinder powers of -2.75 or higher, the answer isn’t always straightforward. Let’s explore the capabilities and limits of toric lenses—and what you can do if your astigmatism goes beyond their reach.

Understanding Toric Contact Lenses

Unlike standard spherical lenses, toric lenses are specially designed to correct astigmatism. They have multiple powers in different meridians of the lens and a particular orientation that must stay stable on your eye to maintain clear vision. Most soft toric lenses can correct up to -2.75 diopters of cylinder power. Beyond that, things become more complicated.

Limitations of Toric Lenses for Severe Astigmatism

Here are some of the challenges associated with toric lenses for high astigmatism:

  1. Limited Cylinder Power Range
     Not all brands manufacture toric lenses beyond -2.75 cylinder. While some specialty lenses can go higher, they are less commonly available and may require custom orders, which can be expensive and take longer to deliver.

  2. Stability Issues
     The higher the cylinder correction, the more crucial lens stability becomes. Even minor rotations can cause significant visual distortion for people with severe astigmatism.

  3. Comfort and Fit
     High prescription toric lenses often have a thicker profile, which can affect comfort and oxygen permeability—especially for extended wear.

  4. Visual Quality
     Because of the lens design complexity, even well-fitting high-cylinder toric lenses may not always offer the same sharp vision as glasses or alternative corrections.

What to Do If You Have High Cylinder Astigmatism

If toric contact lenses aren’t meeting your visual needs or are simply unavailable in your prescription, don’t worry—there are other options worth considering:

1. Custom Soft Toric Lenses

For people with high astigmatism, custom-made soft lenses offer a tailored solution. These lenses are manufactured to precise specifications to match your eye’s unique shape and prescription needs.

Pros:

  • Greater range of cylinder power

  • Better stability and vision

  • Improved comfort with custom fit

Cons:

  • Higher cost

  • Requires more time for ordering and fitting

2. Rigid Gas Permeable (RGP) Lenses

RGP lenses are smaller, firm lenses that hold their shape on the eye and can provide crisp vision by creating a smooth refractive surface.

Pros:

  • Excellent visual clarity

  • Can correct high levels of astigmatism

  • Durable and long-lasting

Cons:

  • Longer adaptation period

  • May feel less comfortable initially

  • Can be dislodged more easily during physical activity

3. Hybrid Contact Lenses

Hybrid lenses combine the best of both worlds: a rigid center for sharp vision and a soft outer skirt for comfort.

Pros:

  • Great for high astigmatism

  • More comfortable than RGPs

  • Offers stable, clear vision

Cons:

  • More expensive than standard soft lenses

  • Can be harder to find and fit

4. Scleral Contact Lenses

Scleral lenses are large-diameter lenses that rest on the white of the eye (sclera) and vault over the cornea.

Pros:

  • Excellent for irregular or severe astigmatism

  • Very stable with minimal rotation

  • High oxygen permeability and comfort

Cons:

  • Requires expert fitting

  • Higher cost

  • Longer learning curve for insertion and removal

5. Refractive Surgery

For those looking for a permanent correction, procedures like Toric ICL (Implantable Collamer Lens) or LASIK/PRK for astigmatism may be options, depending on eye structure and health.

Note: Not everyone is a candidate for refractive surgery, especially with high prescriptions. A detailed eye exam is essential before considering surgery.

Toric contact lens are a reliable solution for many, but they do have limitations when it comes to severe astigmatism. If you’ve struggled to find lenses that work for your high cylinder power, speak with your eye care professional about custom toric lenses, RGPs, hybrids, or scleral lenses—each offering better vision and comfort for specific needs.

  Color contact lenses are a fantastic way to enhance or change your eye color while enjoying clear vision. However, some users experience dryness and discomfort when wearing them. If your color contact lenses feel dry, it can be frustrating and even affect your overall eye health. In this article, we explore the common causes of dryness and offer practical solutions to keep your eyes comfortable and hydrated. Common Causes of Dryness When Wearing Color Contact Lenses 1.
