How are intraocular lenses implanted?

Lens implantation is performed under local anesthesia and usually takes 10-20 minutes for each eye. The basic steps of the process are:

1. Anesthesia and preparation: Anesthetic drops are placed in the eyes to prevent pain during the procedure.
2. Small incision: A very small incision is made in the cornea to insert the lens.
3. Removal of the natural lens (if necessary): In cases of cataract, the cloudy lens is removed first.
4. Inserting the new lens: The foldable artificial lens is inserted and fixed inside the eye.
5. Spontaneous wound closure: Because the opening is small, it heals spontaneously without the need for stitches.
