Do a few inverted eyelashes need surgery?
If there are only a few inverted eyelashes, electrolysis of the eyelashes can be conducted. If there are many, surgical correction can be considered. The technology for surgical correction is currently quite mature, so there are generally not many problems. Inverted eyelashes must be treated. If left untreated, they can cause damage to the cornea. Damage to the cornea can lead to the growth of new blood vessels, resulting in a thin haze over the cornea, spots, and white patches, severely affecting vision. Although inverted eyelashes might seem like a minor issue, if not treated promptly, they can lead to serious complications. However, complete recovery is possible with treatment. It’s important to rest regularly, reduce close-up tasks, and use some corneal protective eye drops, such as sodium hyaluronate eye drops, and anti-inflammatory eye drops, such as levofloxacin eye drops. (Please use medication under the guidance of a doctor.)
Can inverted eyelashes be fixed with an eyelash curler?
In general, it is not advisable to pluck inverted eyelashes with tweezers, as the more you pluck, the thicker the inverted eyelashes become, making them more likely to injure the cornea and conjunctiva. This means the eyelashes become harder, creating a vicious cycle. If you have inverted eyelashes, it’s important to actively treat the condition: if there are few eyelashes, electrolysis can be done; if there are many, corrective surgery for inverted eyelashes is recommended and generally effective. During the period of dealing with inverted eyelashes, you should use anti-inflammatory eye drops and eye drops that protect the corneal epithelium, such as Levofloxacin eye drops and Sodium Hyaluronate eye drops. It's important to rest, avoid rubbing your eyes with dirty hands, maintain a light diet, avoid spicy and irritating foods, and monitor your vision.
Does nearsightedness surgery require an incision?
There are two types of myopia surgery. One is performed using lasers, and the other involves making a small incision on the edge of the cornea to implant an artificial lens into the eye. Corneal laser surgery uses a laser to create a concave mirror on the cornea to resolve the symptoms of blurry vision when looking at distant objects. The ICL surgery, which involves the implantation of an artificial lens, significantly improves the patient's vision after the procedure. Both types of myopia surgeries are currently quite advanced in terms of technology. Therefore, patients who wish to stop wearing glasses and have clear indications from pre-operative examinations can consider undergoing myopia surgery treatment.
What will happen if trichiasis is not treated?
If trichiasis is not treated and allowed to progress, it can cause damage to the conjunctiva and the cornea. Particularly, corneal damage can lead to keratitis and corneal neovascularization, severely affecting vision and the transparency of the cornea. During treatment, if scarring occurs, such as thin corneal opacities, plaques, or leukomas, it can severely affect vision, and even lead to blindness. Therefore, while trichiasis itself is not severe, not treating it can lead to serious consequences. Currently, the main treatments for trichiasis include electrolysis of the eyelashes and surgical treatment, along with the use of eye drops, which generally results in a quick recovery.
Can vision affected by trichiasis be restored?
If trichiasis affects vision, it indicates that the abrasion of the cornea by the eyelashes has reached a certain degree, and active treatment is necessary. The main goal of the treatment is to prevent the future formation of corneal haze, spotted haze, or leukoma, which can severely impact vision. With active treatment, these conditions generally do not develop, so although trichiasis is a minor condition, if not treated actively, it can lead to serious complications. The primary treatments for trichiasis involve the use of eye drops, such as levofloxacin eye drops and sodium hyaluronate eye drops. If the number of misdirected lashes is small, electrolysis of the eyelashes can be performed. If there are many, surgical treatment may be necessary to correct the inward turning of the eyelid. With active treatment, complete recovery is generally possible. (Please use medication under the guidance of a doctor.)
Does nearsightedness imaging fall in front of or behind the retina?
The image in a nearsighted eye forms in front of the retina, whereas in farsighted eyes, the image forms behind the retina. Nearsightedness means seeing clearly up close but blurry at a distance. When nearsighted, appropriate measures such as pupil dilation, optometric examination, and corrective lenses should be taken, or orthokeratology may be used. Once the degree stabilizes and no further progression occurs, surgical treatment can be considered after the age of 18. When the eye is unaccommodative, and parallel light rays enter, they focus in front of the retina. After these occurrences, with proactive treatment and proper rest, efforts should be made to prevent further increase in the degree. Especially in children, attention should also be paid to the development of strabismus and amblyopia.
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.
The difference between conjunctivitis and keratitis.
Eye membrane inflammation generally refers to the whites of the eyes, which is conjunctivitis, while corneal inflammation refers to the black part of the eyes. Both conjunctivitis and corneal inflammation should be actively treated. The symptoms of conjunctivitis include red eyes, swelling, pain, tearing, photophobia, increased secretion, foreign body sensation, and burning sensation, generally not affecting vision. In addition to the above symptoms, corneal inflammation has more pronounced symptoms of corneal irritation, such as increased sensitivity to light and more severe tearing. If corneal inflammation is not actively treated, it may later lead to thinning of the cornea, spots, and opacities, severely affecting vision. If not treated properly, corneal ulcers can perforate, leading to complete loss of vision, or blindness.
Can trichiasis be noticeable?
Trichiasis can be clearly seen with the naked eye; it causes friction on the conjunctiva, either on the sclera or the cornea, leading to damage to the corneal epithelium. This can result in keratitis, corneal neovascularization, and if not treated promptly, it can lead to further pathological changes in the cornea such as thinning, leukoma, and speckled opacities, severely impacting vision. Simple cases of minimal trichiasis can be treated with electrolysis, but more severe cases should be surgically treated. Complete recovery is possible after surgical treatment for trichiasis.
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.)
