If it is catgut embedding, it may be that catgut embedding penetrated the meibomian, which stimulated the cornea and caused tears.

If it is an incision method, it may be because a part of orbicularis oculi muscle needs to be removed during the operation, resulting in slight palpebral fissure deficiency. In short, as long as the eyeball is not directly damaged during the operation, it will take about 3-6 months to recover from the tears caused by the two methods, so don't worry too much. If it is convenient, you can also go to the ophthalmology department of the local hospital for further examination.

If the answer is satisfactory, don't forget to give me a reward.
