What is dry eye?
Dry eye refers to a type of disease in which the tear film is unstable and the eye surface is damaged due to the abnormal quantity or quality of tears, resulting in eye discomfort. Common symptoms include dry eyes, foreign body sensation, burning sensation, eye redness, itching, stinging, photophobia, wind intolerance, sensitivity to external stimuli, and fatigue.
So, why do you have dry eyes?
There is a protective substrate on the surface of the eyeball, the tear film, which plays a role in keeping the ocular surface moist. The tear film is divided into three layers from the outside to the inside, the outer layer is the lipid layer (secreted by the meibomian glands), the middle is the aqueous layer (secreted by the lacrimal glands), and close to the cornea is the mucin layer (secreted by the goblet cells of the conjunctiva). Absence of any of the three components, oil, water, and mucin, can cause unstable tear film and lead to dry eyes.
Director Zhou Jihong said that many patients suspect that they have dry eye syndrome when they feel dry eyes, but the diagnosis of dry eye syndrome needs to go to a professional eye hospital to determine whether they have dry eye syndrome through slit-lamp examination, tear secretion test, tear film break-up time measurement, corneal topography and other dry eye related examinations, and according to the severity of dry eye to judge whether they are suitable for laser myopia surgery and recommend medication and **.
Can I have myopia surgery for dry eye?
Before myopia surgery, the doctor will arrange a comprehensive and detailed preoperative examination for the patient, including visual acuity examination, dilated refraction, comprehensive refraction, intraocular pressure, corneal topography, corneal thickness, corneal curvature, etc. The doctor will control the degree of dry eye according to the specific condition of the patient's eyes, and myopia surgery can be performed for patients who meet the indications for surgery.
There is no significant damage to the ocular surface of mild dry eyes, which can be relieved by rest and ** without affecting the surgery;
For moderately dry eye, it is recommended to postpone surgery and perform dry eye first** before surgery is performed after symptoms are relieved
Surgery is not recommended for patients with severe dry eye or corneal lesions. Can myopia surgery cause dry eyes?
Some patients experience dry eyes after laser myopia correction surgery, which is a normal reaction and not everyone will experience it.
Dry eye can be recovered after surgery!
Dry eye due to refractive surgery is self-limiting and temporary, so don't worry too much.
In general, with the repair of wounds, the regeneration of nerve fibers, and the use of artificial tears**, most patients will recover 3 to 6 months after surgery, and the symptoms of dry eye will disappear. During this period, it is important to follow the doctor's instructions, use the medicine rationally according to the doctor's requirements, and have regular follow-up visits.
After myopia surgery, patients need to develop good eye habits, avoid looking at mobile phones, computers and other electronic products for a long time after surgery, and follow the doctor's instructions to use their eyes correctly. You can use the "20-20-20" eye principle, that is, use your eyes for 20 minutes, rest for 20 seconds, and look 20 meters away to make your eyes recover better.
