AI Technical Summary

Problems solved by technology

For example, some foreign bodies are very small, and it is not easy to catch them with tweezers

Although the tweezers are small, the eyeball tissue still needs to have an incision for the tweezers to enter into the eyeball tissue. The incision needs to be much larger than the wound caused by the foreign body to the eyeball tissue. Tweezers will still cause some degree of secondary damage to the eyeball tissue
