The eye was then treated as after anordinary cataract extraction, and made a steady tension never rose above normal, and its vision quicklyimproved to counting, without a lens, fingers at 50 DiAGEAM TO Scale* (enlaeged 2 diameters). Each subdivision represents a square millimetre. The cornea isrepresented as 12 mm., and the linear knife as 2 mm. in width. Theinterrupted line shows the extent and position of the section nowadvocated. This diagram demonstrates that with the puncture andcounter-puncture placed exactly 1 mm. posterior to the cornealmargin, and using a knife just 2 mm. wide, the chord of the incisionis given precisely the dimensions recommended, if only a vestigeless than ^ mm. of iris be left visible above the edge of the knifeduring the transfixion. and with suitable lenses the eye now exhibited can read1 J. fluently, and has distant Vision = j^ Snellen.
