Pseudophakic eyes with multifocal IOLs had better distance and near acuity and range of accommodation than eyes with a monofocal IOL. Slightly lower contrast sensitivity and increased perception of halos by subjects with the multifocal IOL appear to be an acceptable compromise to enhanced near and distance vision.

Noninfectious uveitis is a predominantly T cell-mediated autoimmune, intraocular inflammatory disease. To characterize the gene expression profile from patients with noninfectious uveitis, PBMCs were isolated from 50 patients with clinically characterized noninfectious uveitis syndrome. A pathway-specific cDNA microarray was used for gene expression profiling and real-time PCR array for further confirmation. Sixty-seven inflammation- and autoimmune-associated genes were found differentially expressed in uveitis patients, with 28 of those genes being validated by real-time PCR. Several genes previously unknown for autoimmune uveitis, including IL-22, IL-19, IL-20, and IL-25/IL-17E, were found to be highly expressed among uveitis patients compared with the normal subjects with IL-22 expression highly variable among the patients. Furthermore, we show that IL-22 can affect primary human retinal pigment epithelial cells by decreasing total tissue resistance and inducing apoptosis possibly by decreasing phospho-Bad level. In addition, the microarray data identified a possible uveitis-associated gene expression pattern, showed distinct gene expression profiles in patients during periods of clinical activity and quiescence, and demonstrated similar expression patterns in related patients with similar clinical phenotypes. Our data provide the first evidence that a subset of IL-10 family genes are implicated in noninfectious uveitis and that IL-22 can affect human retinal pigment epithelial cells. The results may facilitate further understanding of the molecular mechanisms of autoimmune uveitis and other autoimmune originated inflammatory diseases.

Implantation of the ICL for correction of high myopia or high hyperopia appears to be a safe procedure with good visual and refractive results immediately. There was no decrease in the transparency or increase in the density of the crystalline lens with the latest generation of the ICL device in the normal group, indicating enhanced safety. Progressive lens opacification in the heterogeneous group shows there are risk factors for cataract formation; ie, type V3 ICL, preexisting lens opacities, and older patient age. Anterior subcapsular opacities are most likely the result of trauma.
