Ophthalmic Foreign Body Needle Microkeratome Spatula Surgical Instruments

The foreign body needle is a specialized surgical instrument used in ophthalmic procedures for the removal of foreign objects from the eye. It is a long, thin, and sharp metal tool that can easily maneuver through delicate eye tissue to extract the foreign body. The needle has a pointed tip at one end, which allows it to pierce through the affected area of the eye while the other end has a handle for easy grip and control.

In ophthalmology, foreign bodies can be lodged in different parts of the eye such as the cornea, conjunctiva, eyelids, or even inside the eyeball. These foreign bodies can range from small dust particles to larger objects like glass fragments or metal shavings. If left untreated, these foreign objects can lead to severe complications such as infections or scarring of the eye’s delicate tissues.

The use of a foreign body needle is necessary in cases where other methods like irrigation or magnet cannot remove the object. The first step in using this instrument involves numbing drops being applied to prevent any discomfort during the procedure. Then, with precise movement and minimal pressure on the surrounding tissue, the surgeon inserts the pointed tip into the affected area and gently moves it around until it touches the foreign body. Once contact with the object is made, slight pressure is applied by pulling back on the handle until it dislodges from its position.
