If you suffer from a condition that interferes with your vision, such as myopia or astigmatism, you have a wide range of treatments available. One interesting option is called orthokeratology and involves wearing special contact lenses, known as ortho-k contact lenses. The following article examines this treatment in more detail.
How They Work
Ortho-k lenses are specially crafted to temporarily correct flaws in your cornea, which is the transparent layer at the front of your eye. The lenses are worn during the night while you are asleep, allowing your to see properly during the day. The correction will last for a limited amount of time, which can vary depending on the patient. In some cases, you might need to wear the lenses every single night to achieve the desired result, while in other instances, you might need to wear them only every other night or once or twice a week.
These lenses have some advantages over your other options for impaired vision, such as wearing glasses or using contact lenses during the day. Many people dislike wearing glasses for aesthetic reasons and also because they can fog up or become distorted after being splattered with rain.
Wearing standard contact lenses during the day can also cause problems in some instances. For example, if you are athletic, contacts can often come out at inconvenient times, such as while you are engaged in a sporting activity. With ortho-k lenses, you don't have to worry about hunting for a contact lens while playing baseball or tennis.
Another benefit of ortho-k lenses is that they are non-invasive. Many people with vision problems prefer to avoid invasive procedures, such as LASIK surgery, as the results from surgery are never guaranteed and complications are always possible.
The cost of ortho-k lenses is somewhat more than traditional contact lenses. This is because special equipment is required to fit the lenses properly and a longer follow-up period is usually involved.
Ortho-k lenses work best for people who have mild cases of myopia, also called nearsightedness, and mild astigmatism. People with advanced cases of these conditions, or who have other types of vision issues, may need to focus on alternative treatments.
If you think that orthokeratology might be right for you, make an appointment with your eye specialist and ask for their recommendation. They can tell you whether this type of treatment is likely to have a good result for you. To learn more, contact a company like Bass River Optometrics.
