Abstract
The principal method of cataract treatment is microsurgical removal of the opaque natural lens from the eye and implantation of the artificial lens. Now offered types of the artificial lenses differ in its configuration, materials, methods of its fixation in the eye and other parameters. We performed the comparative study of the results of implantation of various types of artificial lenses in respect of visual rehabilitation of the patients. After the implantation of the artificial lens we studied the visual acuity of the patient, the post-operative refraction of the eye, and the patient complaints of visual discomfort caused by various optical effects and aberrations. Among these patient complaints we marked: reducing of the vision at the bright side light, the appearance of the light spots, halo, and chromatic coloring of the outlines of the objects, etc. The correlation between the spectral transmittance of the artificial lens and the distortion of the color perception was studied too. The surface properties of the lens material were accounted as the factor of the biocompatibility of the lens. The consideration of the artificial lens properties makes more precise the determination of the indications and contraindications for the implantation of various types of the artificial lenses.
