[Effect of cataract extraction on the results of in vivo spectrophotometry of the eye].

The authors compared the results of in vivo spectrophotometry of the eye in persons with a normal lens, in patients with aphakia and after an operation of intraocular lens implantation. The results received show that in the range of 400-500 microns half of the light registered by the spectrophotometer is connected with the lens in the eye. This speaks for the assumption that in vivo spectrophotometry in this range of the wave length may be one more method enabling an objective evaluation of the transparency of the lens. In the case of patients after operation of implantation of an intraocular lens the quantity of of the light reaching the retina is only slightly larger than in persons with a normal lens.
