Product Description
OC-OI-STDM MaxField Standard 90D

Design

■ MaxField BIO Lenses are made of high transmittance glass for bright, clear images. ■ MaxField 14D, 18D, 20D, 22D and 28D lenses feature computer optimized aspheric designs for maximum resolution and field of view. ■ MaxField Slit Lamp Lenses are made of high refractive index glass and precision double aspheric designs that yield an extremely wide field and sharp image. ■ MaxField Slit Lamp Lenses range from 54D for detailed examination of the macula and optic disc to 120D for a quick clear view of a wide retinal area. ■ Lenses also available in colored mounts. Contact Ocular Instruments for further information.

Technique

■ Commonly known indirect ophthalmoscopy techniques using either the slit lamp or binocular indirect ophthalmoscope should be used. ■ The tapered end of the lens (silver end of the 14D, 18D, 20D, 22D, 28D, 30D, 35D, 40D and Standard 90) should be held toward the patient's eye during examination. It is important to recognize that this unidirectional design provides the best image quality possible. ■ Keep the lens centered on the patient's pupil. ■ Hold the lens far enough from the patient's eye so that the retinal image is the same diameter as the lens. ■ Keep the illumination source as dim as possible to minimize reflections and loss of image contrast. ■ Use the Ocular Lens Cleaning Cloth (OLCC) to keep lens clean and minimize glare from the lens surface.

Surgical Technique - Osher MaxField 78 Diopter

■ A non-contact Surgical Panfundus Lens designed to allow the surgeon to quickly view the retina through the surgical operation microscope with minimal refocusing. ■ Its wide field of view facilitates the diagnosis of an intraoperative choroidal hemorrhage of an effusion. ■ It is also helpful in identifying lens fragments, a dislocated intraocular lens, or the site of a perforated globe. ■ Offers an exceptionally wide field of view for a non-contact lens and has superb resolution for evaluation purposes. ■ Some retinal surgeons use the Osher MaxField lens to check the retina after band/buckle surgery, thus eliminating the need to use the more cumbersome indirect ophthalmoscope. ■ Under the surgical microscope, position the lens approximately 7mm above the patient's cornea. ■ Elevate the surgical microscope between one and two inches (2.5 to 5 centimeters) until the patient's retina becomes clearly focused.
