Trichiasis can cause the eyes to tear. Patients with trichiasis exhibit significant tearing symptoms because the cornea is rich in nerve endings and is very sensitive to foreign stimuli. In trichiasis, the eyelashes poke and irritate the cornea, thus stimulating the nerve endings and causing reflex tearing. Therefore, patients with trichiasis should be treated promptly to avoid irreversible damage to the cornea, such as scars or corneal ulcers. For minor trichiasis, local electrolysis can be used to destroy the hair follicles so they no longer grow; for more severe cases, it is recommended to visit a hospital for surgical correction of the trichiasis.

How to deal with inverted eyelashes

For trichiasis, it first depends on the nature of the ingrown eyelashes. If there are only a few, such as one or two, it is recommended to pluck them out. For some people, once these are plucked, the new eyelashes may grow back in the correct position, so no further treatment is necessary. If the ingrown eyelashes recur repeatedly as individual lashes, electrolysis of the hair follicle can be performed to destroy the follicle, preventing the eyelashes from growing back. However, because this is a destructive procedure, many hospitals have discontinued it, though some still offer this treatment. If there are many ingrown eyelashes, appearing in rows, the treatment depends on the position of the eyelid. Eyelash correction surgery may be necessary. Depending on the specific situation, excision of the tarsal plate to correct the trichiasis can be considered as well.

Entropion usually falls under the ophthalmology department.

Trichiasis should be treated by an ophthalmologist. Trichiasis is an eye condition caused by the tension factors of the eyelid's soft tissue, leading to the eyelashes attaching to or poking the surface of the eyeball, causing discomfort in the eyes. Depending on the severity of the condition, the following treatments can generally be chosen: First, if it is just a few lashes, electrolysis can be performed on these eyelashes. Electrolysis can destroy the few lashes stimulating the eyeball, preventing their regrowth and thereby relieving trichiasis. Second, if there are a larger number of lashes involved, trichiasis correction surgery should be chosen, which is a surgical treatment. After the surgery, the eyelashes can be made to turn outward, no longer irritating the eyeball.

Can people with trichiasis undergo myopia surgery?

Generally, people with trichiasis should not undergo myopia surgery, as trichiasis primarily affects the eyeball. It causes abrasion to the cornea, affects the corneal epithelium, and can lead to neovascularization of the cornea and corneal pathology. Following the occurrence of trichiasis, surgical treatment should be considered. If there are only a few ingrown lashes, electrolysis of the eyelashes might be performed. After active treatment and once the condition has stabilized, the possibility of undergoing myopia surgery can be considered. Current options for myopia surgery include corneal laser reshaping surgery and ICL (Implantable Collamer Lens) surgery.

Can opening the eye corner cure trichiasis?

Trichiasis, if caused by epicanthus, can be corrected by canthoplasty. If it is not caused by epicanthus but by entropion of the eyelid, canthoplasty will not be effective. For trichiasis with few lashes involved, electrolysis can be used for treatment. If there are many lashes involved in trichiasis, entropion surgery can be performed. The surgery is minor and complete recovery is possible; usually, dressings are changed after surgery and recovery can be expected within about a week. If trichiasis severely wears down the cornea, active treatment should be sought to protect vision and the cornea.

Does trichiasis need to be corrected?

Trichiasis must be treated because it can cause damage to the conjunctiva and cornea. Damage to the cornea can lead to unnecessary corneal inflammation, thinning of the cornea, spotty opacity, scarring, and neovascularization, seriously affecting vision. Therefore, proactive treatment is essential. If there are only a few lashes involved in trichiasis, electrolysis can be used for treatment. If there are many lashes involved, surgical treatment is necessary. During this period, anti-inflammatory eye drops should be used, such as levofloxacin eye drops and erythromycin eye ointment, along with eye drops that protect the corneal epithelium, such as sodium hyaluronate and calf blood deproteinized extract drops. With these treatments, complete recovery is possible. (Please use medication under the guidance of a doctor)
