[Two new types of keratoscope and their clinical application]

The author reports the clinical application of his 2 new types of keratoscope for qualitative observation of the corneal curvature: the reflective type and the transparent type. The latter was particularly useful in controlling the corneal astigmatism during intraocular microsurgery. According to practical use on 30 patients, the positive rate of astigmatic detection and the recognition of astigmatic meridian by these keratoscopes were satisfactory.
