A photo of strabismus surgery, surgery on the extraocular muscles to correct misalignment of the eyes, being performed. In this image, the face appears upside down, and the surgeon is disinserting the medial rectus muscle. A Castroviejo locking forceps is grasping the superior pole of the muscle, while a Manson-Aebli scissors does the cutting. The eyelids are being held by a Cook speculum.
