What are the symptoms of trichiasis?

Trichiasis surgery mainly has the following methods: 1. Extraction method Trichiasis can be directly extracted with eyelash tweezers, simple and effective, but because the hair follicles of eyelashes are not destroyed, they are easy to relapse within a few weeks. The eyelashes that grow out again will be thicker and harder, stimulating the cornea, so extraction is only in the case of poor conditions and no other way, or in the case of other methods trying to be ineffective, as a last resort. 2. Electrolytic destruction of hair follicles and extraction, sometimes repeated multiple times to achieve the desired effect, the success rate is about 10~20%. 3. Cryotherapy can relieve numerous trichiasis. Potential complications include depigmentation of the skin, postoperative eyelid notch, damage to the meibomian glands, and effects on tear film stability. 4. Laser therapy Laser dissection is effective for a few scattered trichiasis. 5. Surgical removal of hair follicles in various methods, this method is better, but if too much trichiasis, failed to deal with once, resulting in entropion, can be operated again. The common surgical methods for correction of entropion include skin orbicularis oculi muscle resection, upper eyelid embedding method to correct entropion, lower eyelid suture pressure method to correct entropion, etc. If there are problems related to trichiasis, it is recommended to consult a professional ophthalmologist. The doctor will recommend the most suitable surgical method according to the severity and specific conditions of trichiasis.
