routine equipment for ophthalmic surgery - answer✔ophthalmic stretcher with attachable wrist rest for
the surgeon; a donut for positioning the head; electrosurgical unit (ESU)
Phacoemulsifier - answer✔used in surgical treatment of cataracts; uses ultrasonic energy to fragment
the hard lens material, which then can be aspirated from the eye
operating microscope - answer✔an integral part of ophthalmic surgery; magnifies surgical site through
use of lenses; may be draped, or reusable sterile handles placed on control knobs
Vitreoretinal system - answer✔used in all posterior chamber surgeries; allows control of intraocular
pressure by irrigation and aspiration; provides light, suction, diathermy, and intraoperative access to the
surgeon
Argon or Nd: YAG laser - answer✔used for photocoagulation or photodynamic therapy

seal tears and holes; nitrous oxide gas passed is under pressure through flexible tubes to the tip of a

practical considerations of ophthalmic surgery - answer✔talking and movement should be kept to a
minimum, as the patient is often awake; nonpowdered gloves should be used; extra care should be

portable microscope is used, it should be brought over the patient from the side opposite the operative

procedures on the eyelid of conjunctiva require the use of a head drape
