We have studied insulin binding to erythrocyte receptors in a group of 25 nonobese, nondiabetic uremic patients undergoing maintenance hemodialysis for 2-54 months and 14 healthy controls. Erythrocytes of predialyzed uremics bind significantly less insulin than control erythrocytes (p less than 0.01). Dialysis resulted in a rapid increase of insulin binding(More)
Purpose. To evaluate visual, refractive, and contrast sensitivity outcomes, as well as the incidence of pseudophakic photic phenomena and patient satisfaction after bilateral diffractive trifocal intraocular lens (IOL) implantation. Methods. This prospective nonrandomized study included consecutive patients undergoing cataract surgery with bilateral(More)
PURPOSE To evaluate the visual, refractive, and contrast sensitivity outcomes, as well as the level of photic phenomena, after cataract surgery with implantation of a trifocal diffractive toric intraocular lens (IOL). METHODS This prospective study included 56 eyes with corneal astigmatism of 1.00 diopters (D) or greater of 28 patients (age: 23 to 78(More)
To investigate factors responsible for altered insulin sensitivity in uremia, we studied 125I-insulin binding to erythrocytes in 20 uremic patients before and after dialysis. In uremic patients, predialysis binding was 50% lower in comparison with healthy controls (4.35 +/- 1.79 vs. 9.37 +/- 1.30%; p less than 0.01). Five-hour dialysis treatment resulted in(More)
Insulin binding to erythrocytes obtained from uraemic patients was determined using a radioreceptor assay. The binding was reduced by 50 per cent in 20 non-diabetic uraemic patients in comparison with 20 controls (4.7 +/- 1.79 vs 9.37 +/- 1.30 (mean +/- SD) p less than 0.01). During the course of haemodialysis insulin binding steadily increased in a time(More)
Insulin binding to specific erythrocyte receptors was investigated in group of 25 subjects with Klinefelter's syndrome (47 XXY genotype) and 14 healthy male volunteers. Insulin binding was significantly decreased in Klinefelter subjects (P less than 0.01 at insulin concentrations of 0.051 and 0.136 mmol/liter); however, their fasting glucose concentration(More)
Previously, we have shown that insulin binding (IB) to erythrocytes was decreased in uremic patients and that hemodialysis corrected the receptor defect. In the present study cross-incubation experiments were performed using uremic and control erythrocytes and plasma. Incubation of control erythrocytes with uremic plasma resulted in a 60% decrease in(More)
Evaluation of an electronic reading desk to measure acuity in pseudophakic patients. Influence of additional astigmatism on distance-corrected near visual acuity and reading performance. Dexl AK. Bilateral reading performance of 4 multifocal intraocular lens models and a monofocal intraocular lens under bright lighting conditions.
