If you have been diagnosed with keratoconus, you may have a lot of questions about the condition and how to manage it. Here are some of the most common questions people with keratoconus ask, along with answers to help you better understand this condition and how to manage it.
What is keratoconus?
Keratoconus is a progressive eye condition that causes the cornea, the clear front surface of the eye, to become thin and irregular in shape. This can cause vision to become distorted and blurry, and can even lead to vision loss if left untreated.
What causes keratoconus?
The exact cause of keratoconus is not known, but it is thought to be a combination of genetic and environmental factors. Some studies have suggested that keratoconus may be more likely to occur in people who have certain medical conditions, such as allergies or asthma, or who rub their eyes frequently.
How is keratoconus diagnosed?
Keratoconus is typically diagnosed by an optometrist during a routine eye exam. Your optometrist may use a special test called corneal topography to create a detailed map of the cornea and look for signs of keratoconus.
What are the treatment options for keratoconus?
One of the most effective treatment options for keratoconus is the use of scleral lenses. Scleral lenses are larger than traditional contact lenses and are designed to fit over the entire cornea, providing a stable and comfortable fit. Because scleral lenses do not put any pressure on the cornea, they can help to slow the progression of keratoconus and improve vision.
Can keratoconus be cured?
At this time, there is no cure for keratoconus. However, treatment can help to slow the progression of the condition and improve vision. In some cases, surgery may be recommended to help improve vision and reduce the symptoms of keratoconus.
Are scleral lenses safe?
Scleral lenses are generally considered to be safe for use by people with keratoconus. These lenses are custom-made to fit the individual’s eye and are carefully fitted by a trained optometrist. As with any type of contact lens, it is important to follow the recommended care and cleaning instructions to help prevent infections and other complications.
Can scleral lenses be worn overnight?
Scleral lenses are not designed to be worn overnight. These lenses should be removed before sleeping and properly cleaned and disinfected before being worn again. Wearing scleral lenses overnight can increase the risk of infection and other complications.
How often do scleral lenses need to be replaced?
The frequency of replacement for scleral lenses depends on the individual’s needs and the type of lenses being used. In general, scleral lenses should be replaced every one to two years, or as recommended by your optometrist. It is important to replace scleral lenses as directed to ensure optimal vision and prevent complications.
Can scleral lenses be used with other vision correction options?
Scleral lenses can often be used in conjunction with other vision correction options, such as eyeglasses or traditional contact lenses. In some cases, scleral lenses may be used as an alternative to corneal transplant surgery. It is important to discuss all of the available treatment options with your optometrist or eye doctor to determine the best course of action.
