چکیده

The aim of our work has been to determinate changes of optical-anatomical elements of 1 myopic eyes during accommodation using precise ultrasonic biometry. The first group 6-10 years old children (n=23) and the second group 11-15 years old children (n=75) eyes were investigated. There was no changes in anterior chamber depth, lens thickness and vitreous length during accommodation. After medicamental threatment (spasmolitic solution) accommodation of the eyes was restored and lens changes reached to 0.31mm (p<0.001) in the first group and to 0.32mm (p<0.001) in the second group. Ultrasonic biometry is one of objective methods to investigate possibilities of eyes accommodation and to evaluate the effectiveness of the chosen method of treatment to restore accommodation function.

Ultrasonic biometry of myopic eyes in premature children

Background. The aim of our work was to determine changes in opticalanatomical elements of myopic eyes of full-term and premature children during accommodation by means of precise ultrasonic biometry. Materials and methods. The study was made on healthy full-term children’s eyes with emmetropic refraction (group, n = 20); full-term 1st degree myopic children’s eyes with refraction from -1.0 D to...

Corrigendum: Corneal Power, Anterior Segment Length and Lens Power in 14-year-old Chinese Children: the Anyang Childhood Eye Study

To analyze the components of young Chinese eyes with special attention to differences in corneal power, anterior segment length and lens power. Cycloplegic refractions and ocular biometry with LENSTAR were used to calculate lens power with Bennett's method. Mean refraction and mean values for the ocular components of five different refractive groups were studied with ANOVA and post-hoc Scheffé ...

Longitudinal changes of optical aberrations in normal and form-deprived myopic chick eyes

We performed measurements of refraction (with retinoscopy), axial length (with ultrasound biometry) and ocular aberrations (with a custom-built Hartmann-Shack aberrometer) on seven awake White-Leghorn chicks occluded monolaterally with diffusers for two weeks. Treatment started on the first day after hatching (day 0) and measurements were conducted on several days between day 0 and 13. Non-occl...

Partial Coherence Laser Interferometry in Highly Myopic versus Emmetropic Eyes

PURPOSE To investigate the reliability of partial coherence laser interferometry for optical biometry in highly myopic eyes. METHODS Axial length measurements by the IOLMaster (Carl Zeiss Meditec, Germany) with signal-to-noise ratio (SNR) ≥2 were performed in 52 consecutive myopic subjects with axial length ≥26.5 mm and 45 emmetropic patients before cataract surgery. Axial length measurements...

The Analysis of Refraction and Accommodation of Extreme Myopia with Cataract after Phacoemulsification and IOL Implantation

Background: To assess the refractive status of cataract patients with extreme myopia and to measure their accommodative capability after monofocal IOL implantation. Design: Prospective non-randomized study conducted at Tianjin Medical University Eye Centre. Participants: 18 patients with 34 extreme myopic eyes (≥-10 Diopter, ≥27mm axial length), and 14 patients with 27 non-myopic eyes that had ...
