Intra-ocular light scatter in pseudophakia.
In 22 patients (23 eyes), who had undergone an uncomplicated cataract extraction with implantation of a posterior chamber lens in otherwise normal eyes 11 to 44 weeks previously, the intra-ocular light scatter was measured with an IOI stray light meter. All the eyes examined had little or no after-cataract. A regression curve for stray light values in normal eyes as function of age was used as reference. The measurements show that the intra-ocular light scatter in pseudophakic eyes with little or no after-cataract increases by a factor 2. This increase must be caused by the combination implant lens-posterior capsule.
