Refractory Issues

Guide to Refractory Issues and Treatment in Las Vegas, NV

If you have trouble with your vision, chances are high that it’s due to a refractory problem. The Centers for Disease Control and Prevention (CDC) reports that refractory issues are the most common cause of eye problems. So what are these refractory issues, and how can they be corrected? Our optometry team at Advanced Eyecare in Las Vegas, NV, answers those questions and more in this guide.

Refractory Issues

What Is a Refractory Problem?

The lens and cornea can properly focus light when an eye is shaped like a sphere. In other words, a clear image is sent to the retina. Yet, not everyone’s eyes are shaped like a sphere. When this is the case, your eyes cannot appropriately refract light. In short, the image sent to the retina is unclear, meaning you see fuzzy or blurry images.

What Are the Most Common Refractory Issues?

Refractory problems tend to come in four types, depending on the exact shape of the eye. These include the following:

  • Myopia – This is another word for nearsightedness. It occurs when the eyeball has grown too long, causing the light to focus incorrectly.
  • Hyperopia – This is commonly known as farsightedness, which occurs when the eyeball is too short, or the lens isn’t shaped well enough for proper refraction. It causes up-close objects to be blurry.
  • Presbyopia – Presbyopia is when your up-close vision worsens with age.
  • Astigmatism – Astigmatism is an issue in which your cornea or lens's curvature is imperfect. This refractory issue can make up-close objects and objects in the distance blurry.

How to Correct These Issues

Treatment for refractory issues typically falls into one of three categories, as listed below.


Eyeglasses are the most common way to correct vision issues. The eyeglass lens will address your refractory problem, ensuring the light reaches the retina. For children, eyeglasses, when used early enough and consistently, can often permanently address these issues.

Contact Lenses

Contacts work in much the same way as eyeglasses. However, they provide the benefit of not having to wear frames. In addition, either daily lenses or extended wear can assist with other eye issues.


Surgery, such as laser eye surgery, can be used to reshape your cornea and provide more permanent results. This treatment is often the best option for adults who want to avoid wearing contacts or eyeglasses.

After determining the type and severity of your refractory error through testing, our optometrist will discuss the best treatment options and refer you to a trusted ophthalmologist for surgery.
