How long does viral keratitis take to heal?

Viral keratitis is also a relatively common type of keratitis. There are many causes of keratitis, both internal and external. Inflammation is often caused by bacterial infection. Generally, as long as good medication is used for treatment, good therapeutic effects can be achieved within a few days, and it can be completely improved in about a week. Of course, this is also related to the patient's condition and immunity.

How long does it usually take for keratitis to heal?

1. If the patient is caused by some external reasons, the treatment time is generally not very long. Generally, the situation will gradually improve through cleaning with some salt water or hot compress, but you must pay more attention to the use of your eyes. However, if keratitis caused by external factors is not very serious, it can generally be cured in about a week. However, the length of time depends on your own condition and physical condition.

2. If keratitis is caused by internal factors, it depends on what disease it is. If it is some serious disease, it will take a longer time to cure the disease, usually about half a month to recover. If the disease causing this condition is not very serious, then the time to cure keratitis will be shorter. However, the specific time it takes to recover depends on your physical condition. If your resistance is better, the disease will recover faster. It is also related to your care during the treatment. If the care is good, the disease will definitely heal faster.

Why do colds cause keratitis?

Experts point out that this is because after catching a cold, patients will constantly wipe their noses and cover their mouths with their hands when sneezing, which makes it easy for the eyes to be infected by the virus.

When you have a cold, your hands are covered with a lot of germs, which can easily enter your eyes and contaminate your cornea when you take out or put on contact lenses. When you have a fever, the local resistance of the eyes decreases, tear secretion decreases, bacteria multiply in large numbers, and their metabolic products are deposited between the cornea and the lens, reducing the oxygen permeability of the contact lens and easily causing eye diseases.

Experts also said that the weather is dry in winter, with a large temperature difference between indoor and outdoor areas, and many people suffer from colds and coughs, as well as many patients with ocular surface diseases. A large proportion of these cases are transmitted through wearing contact lenses. In addition, improper use of medication by patients can also aggravate eye diseases.

Ocular surface experts at the Ophthalmology Hospital remind:

If you wear contact lenses and catch a cold or fever, it is best not to use them and wear frame glasses instead. In addition, even if you wear contact lenses, you should be careful when choosing medicine, because many anti-cold, cough and pain relief medicines contain ingredients that inhibit tears.

Reduced tear secretion can cause contact lenses to become too dry and less transparent, thus affecting vision. The cornea itself is prone to dryness. If the moisture content of the cornea is artificially reduced, it can easily lead to inflammations such as keratitis and conjunctivitis, causing redness, itching, and a foreign body sensation in the eyes.
