During retinal detachment repair, an ophthalmologist performs a procedure to manipulate the retina back to into position after it has become torn or detached. Laser surgery, cryotherapy, vitrectomy, retinopexy, and sleral buckle surgery are all common methods of detachment repair. Instruments commonly used in retinal procedures include cannulas, corneal markers and forceps, hooks and retractors, scissors, and speculums.
