Abstract
In his paper on quantitative assessment of corneal sensitivity, Boberg-Ans1 mentions the decrease of sensitivity after scarring in the adjacent cornea. A similar reduction of sensitivity after cataract sections has been recorded.2 The extent, the duration, and the distribution of the lowered sensitivity seems of interest, especially in relation to the tolerance of contact lenses. Corneal dystrophy after cataract surgery, comparison of corneal and limbal sections, are aspects worthy of consideration in regard to their corneal sensitivity. Method For the examination of corneal sensitivity, a modified version of the method as described by Boberg-Ans3 was used. Instead of 1 nylon thread of a 00000 dermalon suture, a double thread of approximately 50 mm. was used, fusing the ends by heating over a Bunsen burner. By feeding the double thread into a thin polyethylene tube, it was possible to change the length of the nylon thread and thus
