There are various possible measures to treat trichiasis, including the following:

1. Eyelash removal: This is a simple and cheap method. If trichiasis cannot be performed for some reason, it is an effective treatment.

2. Hair follicle electrolysis: This is a relatively simple method, but it needs proper equipment. A two-year follow-up report pointed out that the success rate of mild trichiasis was about 25%.

3. Cryopreservation of eyelashes: Just like electrolytic hair follicles, we need suitable equipment and learn to apply freezing technology to depigment eyelid skin, and its success rate is similar to electrolytic hair follicles.

4. trichiasis surgery: surgical correction of trichiasis is the "last chance" to prevent blindness caused by trachoma and the most urgent action to be taken. There are many surgical methods to correct trichiasis, but one operation is called double tarsal rotation, which is simple and has a high success rate.

According to the above information, the best treatment for trichiasis is surgery. Eyelash removal can only be effective in a short time, and the success rate of electrolytic hair follicle and frozen hair removal is relatively low.
