  • 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.

  • OG3MSA-IR, OG3MSFA-IR & OG3MSA-2-IR lenses incorporate an ergonomic rotating feature that greatly

  • improves rotational control while eliminating the need for two handed adjustments.
