Description
-
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.
