OC-OG3M 3 Mirror Universal, 18mm OD
■ Three Mirror Universal Lenses provide mirrors for the examination of the fundus and the anterior chamber angle.
■ Three mirrors of 59°, 67° and 73° are arranged at 120° intervals.
■ The small 59° mirror is inclined for gonioscopic procedures. It may also be used for the observation of the vitreous and the fundus near the ora serrata.
■ The middle size mirror is inclined at 67° to observe the peripheral fundus from the ora serrata to the region of the equator.
■ The largest mirror is inclined at 73° to observe the fundus from the equator to an area adjacent to the posterior pole.
■ The posterior pole can be observed through the central axis of the lens. Argon/Diode broad band anti-reflective coatings are bonded to the lenses to minimize reflections and maximize light transmission during laser treatment.
■ Ocular Instruments offers seventeen styles of the Three Mirror Universal Lens, seven of which require no methylcellulose (NMR) during routine eye examinations.
■ An unusually flat cornea (K=38.00) may require use of a drop of methylcellulose or Celluvisc between the cornea and the lens on the NMR styles.
