But, contact lenses can help manage this condition well. Knowing how to pick the right lenses can make seeing better and feeling more comfortable.
We will look into how to fit contact lenses for keratoconus. We’ll talk about the different types of lenses and how to choose the best ones. Specialized contact lenses are key to better vision and easing keratoconus symptoms.
Understanding Keratoconus
Keratoconus and Contact Lenses: Optimal Fits Explained Keratoconus is a condition where the cornea gets thinner and bulges. This makes vision blurry. We’ll look into how it affects vision and how doctors Diagnose it.
What is Keratoconus?
Keratoconus makes the cornea thin and cone-shaped. This leads to bad vision. It happens when the fibers that keep the cornea straight get weak. We don’t know exactly why it happens, but genes and environment might be involved.
Symptoms and Diagnosis
Keratoconus can cause: Keratoconus and Contact Lenses: Optimal Fits Explained
- Blurred or distorted vision
- Increased sensitivity to light
- Frequent changes in glasses or contact lenses
- Difficulty seeing at night
To diagnose keratoconus, doctors use several tests. Corneal topography maps the cornea’s shape. Pachymetry measures how thick the cornea is. Slit-lamp exams also help in making a correct diagnosis.
Why Keratoconus Affects Vision
Keratoconus changes how light goes into the eye. This makes vision blurry and double. As it gets worse, glasses and contacts don’t work well anymore. Finding and treating it early is very important.
Keratoconus Treatment Options
Keratoconus and Contact Lenses: Optimal Fits Explained Patients with keratoconus have many ways to treat it, from non-Surgical options to surgical methods. Each way has its own benefits, based on how bad the condition is and what the patient needs. We’ll look at different treatments and how they work and their success.
Non-Surgical Treatments
Collagen cross-linking and custom soft lenses are good choices for those who don’t want surgery. Collagen cross-linking makes the cornea stronger by making collagen bonds stronger. Custom soft lenses fit the cornea’s shape, giving better vision and comfort.
Surgical Treatments
For serious cases, surgical methods like corneal transplants and INTACS ring segments are used. Corneal transplants replace the damaged cornea with a healthy one, greatly improving sight. INTACS ring segments reshape the cornea for better stability and clear vision. These surgical methods are for patients who don’t get better with non-surgical treatments.
Role of Contact Lenses in Treatment
Contact lenses are key in treating keratoconus. They correct vision and support the cornea. RGP and scleral lenses are great because they make the eye surface smooth. These lenses are good for those who prefer non-surgical options or use them with other treatments.
