A 10-yr-old partially sighted, one-eyed patient with 10/200 distance acuity and no experience in using an optical aid was able to read successfully by using a 10 × Selsi telescope with a +3.50 D reading cap, an easel to hold the material upright and free his hands to hold the telescope and write, and a high-intensity desk lamp to provide adequate retinal illumination through a congenital cataract.
