Advantages and disadvantages of laser treatment for myopia

The advantages of laser treatment of myopia are corrected vision, small damage, etc., as follows:

1. Patients with corrected vision

can cut the corneal stroma layer by laser treatment, thus changing the thickness and curvature radius of the cornea to achieve the purpose of correcting vision.

2, damage small

laser treatment of myopia is the laser action on the cornea, generally will not cause damage to other tissues, so the damage is small, and faster recovery.

In the case of standard acceptance of myopia laser treatment, generally will not produce harm, if the operation is improper or poor postoperative care, there may be excessive correction, infection, dry eye and other disadvantages, as follows:

1. Excessive correction If the

operator cuts too much corneal stroma during laser treatment of myopia, it may lead to correction exceeding the expected degree and cause hyperopia in the patient.

2. Infection

If the surgical instrument disinfection is not up to standard, or the eye touches water too early after surgery, it may lead to invasion of pathogenic bacteria and cause infection.

3, dry eye disease If the

lacrimal gland tissue is accidentally damaged during surgery, it may lead to reduced tear secretion, causing dry eye disease.
