In clinical practice, he is bold yet meticulous, good at critical thinking and innovation. In recent years, he has introduced and performed cataract removal surgery with implantation of artificial lenses, restoring sight to many patients. He has accumulated rich clinical experience in the diagnosis and treatment of pediatric refractive errors, eye trauma, and coal mine eye injuries, showing unique skills in surgical treatment.
He has published over 20 papers in international, domestic, provincial, and municipal journals.

Does removing inverted eyelashes have any impact on the eyes?
After removing the misdirected eyelashes, it generally does not significantly affect the eyes. However, if they regrow after being plucked, they tend to be harder than before. Repeated plucking can cause inflammation of the eyelid and conjunctiva, long-term abrasion of the cornea, and may lead to the formation of new blood vessels in the cornea. Sometimes, it can also lead to corneal vascularization. Therefore, plucking is not advised. If there are only a few eyelashes, electrolysis can be performed; if there are many, surgical correction is possible, and generally, the results of the surgery are quite good. In such cases, it is advisable to use anti-inflammatory eye drops and eye drops that protect the corneal epithelium, such as levofloxacin and sodium hyaluronate eye drops. (Please consult a doctor before using any medication.)
The difference between nearsightedness and farsightedness.
Myopia is characterized by clear vision up close and blurred vision at a distance; hyperopia is characterized by clear vision at a distance and blurred vision up close. The main difference between myopia and hyperopia is the issue with the eye’s axial length. In an unaccommodated state, when parallel light rays enter the eye and focus in front of the retina, it is called myopia; when they focus behind the retina, it is called hyperopia. Myopic glasses are concave lenses, while hyperopic glasses are convex lenses. When myopia or hyperopia occurs, it is important to rest, reduce close-up activities, avoid eye fatigue, use eyes properly, eat a light diet, adjust your attitude, have regular check-ups, and pay attention to vision health.
Are the floaters in floater eye disease always black?
Floaters generally appear as black, fixed, variously shaped materials floating in front of the eyes, and are more visible in bright light than in dim light. This condition is called physiological vitreous opacity. If the color turns red or brown, it should be considered as vitreous hemorrhage or retinal pathology, and a further eye examination at an ophthalmology department is recommended. This usually indicates pathological vitreous opacity, which can severely affect vision. For physiological vitreous opacities, it is important to rest, reduce close-up activities, and appropriately use some Ametin iodide eye drops. Treatment can generally lead to improvement.
Trachoma is what type of infectious disease
Trachoma is classified as a Class C infectious disease by national regulations. Trachoma generally manifests as red eyes, swollen eyes, eye pain, increased secretions, and a foreign body sensation, sometimes affecting vision. The conjunctiva in trachoma shows significant proliferative follicles, or pavement stone-like changes. The transmission of trachoma is mainly through contact. Additionally, it is categorized as a Type C infectious disease, with infectious diseases classified into three major categories: Type A, Type B, and Type C. After contracting trachoma, it is crucial to actively treat it with eye drops and to pay attention to eye hygiene.
Is it effective to use glasses for floaters?
Floater syndrome generally does not require glasses, and wearing glasses has no effect. Although floater syndrome involves the refractive media, it does not cause changes in vision. Changes in vision are mainly due to the curvature of the cornea, the condition of the lens, the length of the eye axis, and retinal diseases. Floater syndrome can be physiological or pathological. Physiological floaters generally do not affect vision; simply taking rest, reducing close-up tasks, or using some peptide eye drops can completely improve the condition. If it is pathological floater syndrome, one should visit the ophthalmology department for further examination and active treatment.
Keratitis can be divided into several stages according to pathological changes.
Keratitis can be divided into four stages according to pathological changes: the infiltration stage, the ulceration stage, the ulcer recession stage, and the healing stage. The condition of the cornea differs at each stage, and treatment must be administered accordingly. Treatments include anti-inflammatory eye drops, antiviral eye drops, and eye ointment therapy. When necessary, treatment can involve the use of a corneal bandage contact lens. If it reaches the healing stage, such as when scars form in the anterior elastic layer and the stromal layer, resulting in corneal opacity, nebula, and leukoma, this can affect vision and regular follow-ups may be required.
Can people with trichiasis wear contact lenses?
Patients with trichiasis often experience inflammation of the conjunctiva and the cornea, therefore, they cannot wear contact lenses. Once trichiasis occurs, it should be actively treated, especially targeting the trichiasis itself. If it is just a few eyelashes that are inverted, electrolysis of the eyelashes can be performed. If there are many eyelashes inverted, then surgical treatment should be considered. Once the condition stabilizes, contact lenses can be worn. However, since trichiasis affects corneal lesions, a corneal bandage lens can be worn to protect the cornea. Active treatment with eye drops and eye ointments is recommended, and hot compresses should be avoided.
What will happen if the floater condition becomes severe?
Floater, also called vitreous opacity, can affect vision if it is severe. Vitreous opacity can be divided into physiological and pathological types. Physiological vitreous opacities, generally referred to as floaters, do not affect vision. They are more visible in bright light and less visible in dim light or at night. Treatment primarily involves rest, proper eye usage, and the appropriate use of Amiodine eye drops, with regular check-ups recommended. If vision is affected, further examination in an ophthalmology department is advised, including checks of intraocular pressure, an ocular B-scan ultrasound, and fundus photography, with treatment adjusted according to the condition and regular reviews. (Please use medication under the guidance of a physician.)
Where is massage effective for floaters?
Floaters, also known as vitreous opacities, can be divided into physiological and pathological types. Massaging generally has no therapeutic effect on vitreous opacities. In cases of physiological vitreous opacities, it is important to rest, reduce close-up activities to avoid eye strain, and use treatments like amino peptide eye drops and sodium hyaluronate eye drops. Usually, physiological opacities do not affect vision. However, if the vitreous opacities are pathological and severely impact vision, one should visit an ophthalmologist for an eye examination, including tests for visual acuity, intraocular pressure, ocular ultrasonography, and fundus photography, and pursue active treatment to restore normal vision.
What glasses should be worn for refractive errors?
Refractive errors include myopia, hyperopia, presbyopia, astigmatism, and amblyopia. If it is myopia, concave lenses should be used; convex lenses are used for hyperopia; astigmatism requires cylindrical lenses. If it is strabismus, the appropriate prism should be used. In the case of amblyopia, pupil dilation, optometry, and fitting glasses should be performed, along with active amblyopia treatment. When these conditions occur, proper eye care should be maintained, including adequate rest, reducing close-up activities, avoiding eye strain, regularly revisiting the doctor, and frequent checks and corrections for vision are necessary.
