OC-OMRA-PRP-165 Mainster PRP 165
■ The Mainster PRP 165 Laser Lens has an unequaled 165° static field of view, which is the widest available.
■ Its ultrasharp aspheric optics provide exquisite fundus detail and distortion free laser beam transmission.
■ Its LASERLIGHTŪ HD anti-reflective coatings are optimized for argon, dye, krypton and diode photocoagulators.
■ Has a SECUREFITŪ flange for easy lens manipulation to treat the far periphery.
■ Access the retinal periphery with unparalleled ease to treat proliferative diabetic retinopathy, neovascular retinal vein occlusions or retinal breaks.
■ It is an excellent lens to view and treat through small pupils and opaque media.
■ No methylcellulose is required during routine eye examinations on the OMRA-PRP-165-2 style.
Mainster-series lenses are optimized for the most common retinal applications. As with any new device, there is a brief learning period before lens use becomes instinctive. The following approach works well in most situations:
■ Keep the slit lamp arm in the central position so that illumination, observation and the laser beam (when used) are lined up parallel to each other.
■ Start with low slit lamp magnification.
■ Apply gonioscopic solution to the contact lens element and place it on the patient's cornea.
■ Move the slit lamp forward until a red reflex, and then a retinal image, comes into view.
■ Optimize the image by tilting the lens on the patient's cornea (up, down, left, right).
■ Avoid the natural tendency to let the front surface of the lens drop down.
■ Once the retinal image is seen clearly, increase slit lamp magnification to obtain the desired magnification for your retinal application.
■ Keep illumination as dim as possible and the slit lamp beam as narrow and short as possible to decrease back-scattered slit lamp light that can decrease image contrast and the quality of your retinal view.
To avoid excessive energy to the crystalline lens, laser spot settings of greater than 275 microns are not recommended.
