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.

What should be noted for trichiasis?

Patients with trichiasis should note the following: First, when trichiasis damages the corneal epithelium, causing noticeable symptoms of eye pain, foreign body sensation, photophobia, and tearing, medication that promotes the repair of the corneal epithelium is needed, such as recombinant human epidermal growth factor eye drops, recombinant bovine basic fibroblast growth factor eye drops, etc. Second, once trichiasis leads to conjunctivitis, keratitis, and other infectious eye diseases, it is necessary to promptly use antibiotic eye drops for treatment, such as tobramycin eye drops, ofloxacin eye drops, etc. Third, a small amount of trichiasis can be plucked or treated with electrolysis, but for numerous trichiasis caused by entropion, surgical correction of the entropion is required for cure. (Please follow medical advice when using medications.)

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.

Why did a trichiasis suddenly grow?

A sudden formation of an ingrown eyelash is usually due to chronic inflammation in the eyelid margin area, which causes abnormalities in the eyelash follicles. Consequently, the direction of the eyelash growth no longer points straight forward but instead grows toward the eyeball. As the eyeball moves and blinks, the eyelash rubs against the corneal epithelium, causing noticeable symptoms such as a foreign body sensation, stabbing pain, congestion, redness, photophobia, tearing, and a decline in vision. One can visit the ophthalmology department of a hospital for a face-to-face examination and confirmation of the condition. Removing the ingrown eyelash can alleviate the symptoms, but recurrence is possible. If it recurs repeatedly, electrolysis treatment for ingrown eyelashes can be considered. This involves inserting a specially designed probe deep into the follicle of the ingrown eyelash and then passing an electric current through it. The electric current will destroy the follicle of the ingrown eyelash, making it less likely to recur.

Can trichiasis cause corneal damage?

If trichiasis persists in rubbing against the cornea, it will cause damage to the cornea. Long-term abrasion can lead to corneal neovascularization, damage the corneal epithelium, and leave opacity, sometimes forming speckled opacity or even leukoplakia, severely affecting vision. Once trichiasis occurs, active treatment is necessary. If there are only a few lashes involved, electrolysis of the eyelashes can be done; if there are many, surgery is essential. The surgery for trichiasis is generally successful, fully capable of correcting the condition, protecting the cornea, preserving vision, and alleviating the symptoms of the patient.

Is it normal to have one or two inverted eyelashes?

Having one or two eyelashes growing inwards is abnormal. Normally, eyelashes should not rub against the conjunctiva and cornea. If this occurs, do not pluck the eyelashes. Electrolysis surgery can be performed on the eyelashes, and after the surgery, the inturned lashes will not grow back, thus they will no longer affect the conjunctiva and cornea. If inflammation of the conjunctiva and cornea occurs, anti-inflammatory eye drops, such as levofloxacin, and sodium hyaluronate eye drops, which protect the corneal epithelium, can be used for effective treatment. Generally, these issues are not serious and do not affect vision. However, if vision is impacted, further examination and treatment should be sought from an ophthalmologist.
