Lower eyelid trichiasis surgery

Normal eyelashes grow forward and upward, but there is a situation where it is the opposite, and the eyelashes grow backward, which is called inverted eyelashes. Inverted eyelashes are common in children and the elderly. As they grow toward the eyeball, they will definitely rub the corneal epithelium, causing symptoms such as photophobia and tearing. The use of lower eyelid inverted eyelashes surgery for treatment has very good results. Let's take a look at the relevant information about lower eyelid trichiasis surgery.

Surgical Methods Surgical correction of trichiasis is the "last chance" to prevent trachoma blindness and is the most urgent action to be taken. There are many different surgical procedures to correct trichiasis, but there is one procedure called double tarsal rotation that is simple to perform and has a high success rate. Surgical correction is a corrective surgery performed based on the customer's specific conditions, namely the length of the palpebral fissure, the shape of the eyelid, the distance between the upper eyelid margin and the eyebrow, etc. According to the degree of skin looseness and inversion, excess skin is removed appropriately, as well as the width of the skin removed, that is, the length of the palpebral fissure, the shape of the eyelid, the distance between the upper eyelid margin and the eyebrow, etc., use a slightly bent small wire to test the appropriate position of the double eyelid and use a ruler to determine the point. Gentian violet is used as a mark, with the central point 6 mm away from the eyelid margin, the point between the inner canthus and the central point about 4 mm away from the eyelid margin, and the outer point between the central and outer canthus, generally not lower than the midpoint or 0.5 to 1 mm below the midpoint. Connect the three points along the arc of the eyelid margin and then observe whether the double eyelid is appropriate. The height of the double eyelid line from the eyelid margin should be adjusted appropriately according to the length of the palpebral fissure. The skin is cut along the incision mark. If the upper eyelid skin is too loose, the incision is extended outward to the orbital margin. When it reaches the lateral canthus, it no longer continues downward along the arc but is aligned with the crow's feet at the lateral canthus.
