[Surgical correction of presbyopia with multifocal diffractive intraocular lenses].

The authors analyzed the results of binocular refractive lens exchange with a pseudoaccomodative AcrySof ReSTOR multifocal diffractive intraocular lens (IOL) in 24 patients (48 eyes) aged 40 to 61 years. Preoperative hyperopic refraction ranged from 1.0 to 6.0 diopters. One week postoperatively, a high percentage of the operated eyes had fine results of uncorrected distance and near visual acuity; the mean contrast sensitivity was found to be slightly reduced at high frequencies. 87.5% of the patients were completely satisfied with the results of binocular AcrySof ReSTOR implantation. Refractive lens exchange with an AcrySof ReSTOR multifocal IOL is a reasonable option for presbyopia in hyperopic patients and provides high functional results. A contrast sensitivity reduction on high frequencies on high frequencies can limit satisfactory results after AcrySof ReSTOR IOL implantation in case of some professions.

[Calculation of the diameter distribution function of long hollow cylinders from coherent light scattering data]. / Raschet funktsii raspredeleniia po diametram dlinnykh polykh tsilindrov po dannym rasseianiia kogerentnogo izlucheniia

A method is developed to find the particle-diameter-distribution of noninteracting long hole cylinders by means of integral transform of light- or X-ray-scattering curve. No assumptions need to be made about the form of distribution function.
