Ocular calculi, also called conjunctival calculi, are small, white plaques that grow on the lid conjunctiva. It consists of a mixture of shed conjunctival epithelial cells and concentrated products of mucus that accumulate together to form agglomerates of the conjunctiva and are deposited in the depressions of the lid conjunctiva, forming small white plaques. Over time, it slowly hardens and protrudes from the conjunctiva so that it can repeatedly irritate the cornea and cause foreign body sensation in the eye. Its main treatment is to remove the stone by picking it with a needle. Routinely it can be solved by using a sterile needle under a slit lamp, although care needs to be taken to make sure that it is well cleaned and disinfected so as not to cause local infection. In cases of local inflammation or infectious disease, it is important not to rush to pick out the stones, but to do so after the infection is under control. Because stone removal is a relatively simple operation, many patients will leave it alone after treatment, which is not right. Daily post-operative care is especially important, so be sure to pay attention to clean wound care and make it a habit not to rub your eyes with unclean hands. Patients who wear contact lenses must do a good job of disinfection and maintenance of contact lenses, regular eye examinations, and their diet should also be careful to avoid too spicy, eat more fresh vegetables and actively supplement vitamins. In summary, eye stones, unlike stones in other organs, do not have a true pathological process and generally do not produce complications that can affect vision, so there is no need to be nervous. Moreover, after removal, the stone may still grow again, but as long as there is no discomfort, no treatment is needed. After the removal treatment, care needs to be taken to prevent infection.
