About me
Loudi Central Hospital, Ophthalmology Department, Chief Physician, has been engaged in clinical work in ophthalmology for many years, with rich clinical experience in the diagnosis and treatment of common eye diseases.
Proficient in diseases
Specialize in common diseases such as trachoma, cataracts, diabetic retinopathy, conjunctivitis, presbyopia, color blindness, iris heterochromia, retinitis pigmentosa, and central retinal artery occlusion.

Does cataract spread by contagion?
Firstly, cataracts are the clouding of the lens inside our eyes, known as cataracts. Cataracts are not contagious. Based on the cause, cataracts can be classified into age-related cataracts (previously referred to as senile cataracts), metabolic cataracts, secondary cataracts, traumatic cataracts, and radiation cataracts. The most common type in clinical settings is age-related cataracts, which are commonly seen in middle-aged and elderly individuals over fifty years old. Its clinical presentation is a painless, gradual decline in vision. Currently, the only effective treatment is surgical intervention.
Is cataract easy to treat?
If you are diagnosed with cataracts, we generally use surgical methods nowadays. Our surgical approach typically involves cataract phacoemulsification combined with the implantation of an artificial lens. If you have a simple case of cataracts without any other eye diseases—such as glaucoma, diabetic retinopathy, hypertensive retinopathy, or central retinal vein occlusion—the outcome after surgery is generally good. As for the eye drops for treating cataracts advertised on TV, like Sharp Eye Love, their effectiveness is not very certain in our medical practice. Currently, the main method of treating cataracts is still through surgery.
How to perform surgery for retinal detachment?
Firstly, there are three types of retinal detachment: rhegmatogenous, tractional, and exudative retinal detachment. For rhegmatogenous and tractional retinal detachment, surgical treatment is generally adopted. There are two common surgical methods: one is external surgery, known as scleral buckling, and the other is internal surgery, involving vitrectomy with complex retinal detachment repositioning. The choice of surgical method requires assessment by an ophthalmology specialist before a decision can be made. Exudative retinal detachment is generally treated by addressing the underlying disease and does not require surgery.
Symptoms of cataracts
The symptoms of cataracts are diverse. Firstly, the most primary manifestation is a decline in vision, which is a painless and gradual decrease. Unlike glaucoma, where the decrease in vision is accompanied by swelling pain in the eyes and even headaches, the vision decrease in cataracts occurs gradually and not suddenly. If the onset is sudden, then it is generally not considered to be caused by cataracts. Besides the painless, gradual decline in vision, some patients may experience a decrease in contrast sensitivity, and changes in refraction. For example, patients who have presbyopia might find that their presbyopia diminishes and their nearsightedness worsens if they develop cataracts, particularly nuclear cataracts. Some people may experience monocular diplopia or polyopia, as well as varying degrees of visual field defects.
