Excerpt

The wide-angle viewing system (WAVS) is widely used by vitreoretinal surgeons as it provides a much wider view of the fundus extending from the posterior pole to near the ora serrata.1 In addition, the WAVS provides a better view of the fundus in eyes with opaque corneas or small pupils. To obtain a wider view of the fundus with the noncontact WAVS, the front lens should be placed close to the cornea. Under these conditions, the view of the fundus is occasionally disturbed by condensation of moisture on the surface of the front lens from moisture derived from the ocular surface of the patient.1,2 To solve this problem, the front lens can be moved farther away from the patient's eye, but this leads to a narrower view of the fundus. To solve this problem without reducing the wide view of the fundus, we have developed a device to remove the moisture condensation when it occurs.
