    Author: Jupiter DG.
    Journal: J Am Optom Assoc; 1995 Jan; 66(1):42-6. PubMed ID: 7884141.
    Abstract:
    BACKGROUND: Examination of the inner eye is an important part of any comprehensive eye examination. There are a number of instruments used for examination of the ocular fundus; each has its advantages and disadvantages. Many of these instruments rely on hand-held lenses of which there are a number of options. METHODS: A doublet design lens consisting of two aspheric, plano-convex lenses, which have their convex sides facing toward each other and are separated by an air space, was evaluated and compared with other commercially available condensing lenses. RESULTS: A + 13.5 and +16 diopter doublet lens can be a valuable lens for binocular indirect ophthalmoscopy when compared with currently available, commercially available lenses. CONCLUSIONS: Innovative designs in lenses used with binocular indirect ophthalmoscopy may add considerably to the enhancement of the examination of the ocular fundus.
