Can corneal adhesive therapy treat myopia?

Escort for refractive surgery.

At present, laser surgery requires the thinning of corneal tissue through laser to achieve the purpose of changing corneal curvature and correcting refractive error. However, the thinning of the cornea will inevitably cause changes in the biomechanics of the cornea, resulting in a decrease in the stability of the cornea.

Although in most cases, this change does not cause corneal lesions, but in the case of some disease tendencies of the cornea itself or too much tissue is surgically cut, it can induce problems such as keratoconus. If corneal cross-linking technology is combined after corneal refractive surgery to increase corneal firmness, the biomechanical changes caused by corneal refractive surgery can be alleviated to a large extent, and the safety of the operation is more ensured.

Corneal cross-linking is also called corneal collagen cross-linking, which is a surgical method for the first type of keratoconus, the long-term effect of the operation is still relatively good, under normal circumstances, the hardness of the cornea has been enhanced, the morphology of keratoconus will not continue to develop or aggravate, and the vision of a small number of patients has improved, so if there is keratoconus, corneal cross-linking can be considered. However, this kind of surgery, you must go to the hospital for a detailed examination, make an accurate judgment on the thickness of the cornea, corneal curvature, and have indications for surgery, before you can use this surgical method**, there may be local postoperative reactions in the short term, such as corneal edema, after a period of recovery, vision will slowly recover.

There are many myopic people who want to have myopia surgery, but some people are worried that they will not be able to have myopia surgery because they have suffered from an eye disease (keratitis). So, if you have keratitis, can you still have myopia surgery?

KeratitisThe cornea is a transparent tissue with a certain thickness located on the surface of our black eyeballs, and the inflammation of the cornea is keratitis. Keratitis causes redness around the cornea, while mild epikeratitis may not show any congestion.

The cornea of keratitis is edematous due to inflammation, loses its original luster and transparency, and can also feel halo and affect vision when looking at things, severe keratitis will lead to corneal ulcers, and even corneal perforation, so that microorganisms invade the eye, causing endophthalmitis and blindness.

Symptoms of keratitis may include: eye pain, redness, feeling like something is in the eye, fear of seeing light, tearing, eyelid fluttering, decreased vision, increased droppings, ......

PS: There are many symptoms of keratitis, and every patient may be different.

Can people who have had keratitis have myopia surgery?

Myopia surgery is performed on the cornea, so if you are at the onset of keratitis, you should never undergo myopia eye surgery.

Before myopia surgery, your surgeon will ask about your medical history, and you will need to undergo a detailed and rigorous preoperative examination to ensure that the procedure is safe.

A corneal examination is also included in the preoperative examination. If your keratitis is found to be in the onset stage, you will not be able to undergo myopia eye surgery at this time, and the doctor will not perform surgery on you.

In fact, as long as you pass a full set of preoperative examinations, you can have myopia surgery without worry. The main thing is to choose a professional and regular hospital before the operation, and strictly check the contraindications of surgery.

Eyes that have had keratitis are generally fine with myopia eye surgery, because the surgery is not the cornea but the lens on the eyeball, which has nothing to do with the cornea. It depends on your situation.

Let's improve the situation of keratitis first, myopia can be worn with glasses.

It is advisable to ask the relevant department.
