  • Title: [Visual acuity, refraction and color vision after implantation of foldable silicon lenses].
    Author: Sadowski B, Steuhl KP.
    Journal: Ophthalmologe; 1995 Jun; 92(3):318-24. PubMed ID: 7655206.
    Abstract:
    Implantation of intraocular lenses through a small opening is possible with phacoemulsification and foldable silicon lenses. There is little traumatic effect, which is positive for the healing process and the postoperative results of visual acuity and refraction. Because of alteration of the optic media, deteriorated sensation is possible. We investigated 28 patients with foldable silicon lenses after phacoemulsification. Pre- and postoperatively (1 day, 1 week, 3, 6, 12, 18 and 24 months) visual acuity and astigmatism were measured. As the testing of color vision is a sensitive method for the detection of disturbance in sensation because of altered optic media this was performed 24 months postoperatively using the pseudoisochromatic plates of Ishihara and Ichikawa and the color arrangement tests, Farnsworth Panel D-15 desaturated and the Farnsworth Munsell 100 hue test. The results of this study confirm quicker rehabilitation of visual function and a lower rate of operatively induced astigmatism. A slight blue color vision deficiency results as consequence to altered optic media, but there is no effect on daily life.
