Background: The availability of premium intraocular lenses (IOL), including toric, multifocal, and EDOF, has become very sophisticated now demands accurate biometric measurement accuracy. Pentacam AXL IOL Master 700 are often used for optical biometry they available in the market today. They can also be to measure parameters needed calculation using latest generation formulas, such as Barett Un...

Introduction: This study aimed to evaluate the distribution of contrast sensitivity (CS) using Pelli Robson test in normal individuals over seven years old living Zahedan and examine its relationship with age, gender, refractive errors. Methods: In this cross-sectional study, simple sampling was performed on patients aged their attendants who had referred Al-Zahra eye hospital Zahedan. Complete...

Purpose: To clinically evaluate a new extended depth of focus intraocular lens (ISOPURE, PhysIOL) with optic design modification based on unique polynomial concept to improve intermediate vision while keeping the quality distance equal monofocal lens. Methods: 18 patients (11 female, 7 male, mean age 69.4 years) bilateral cataract and regular corneal astigmatism ? 1.0 D underwent surgery ISOPUR...

Purpose To assess the effect of decentration and tilt combined with prior myopic ablations on optical performance a trifocal intraocular lens (IOL) novel IOL an extended depth focus (EDOF) design. Methods The XACT Mono-EDOF ME4 (Santen Pharmaceutical Co Ltd) FineVision (PhysIOL) IOLs were analyzed without simulated previous ablations. quality was evaluated PMTF bench (LAMBDA-X). through-focus m...

The improvement in nursing routine of premature babies with low and extremely body weight has increased their survival rate. Along the growing number such children, retinopathy prematurity (ROP) occurs relatively less often its outcome becomes more favorable. Modern approaches to surgical treatment have led a significant reduction incidence blindness visual disability caused by ROP. Yet, ROP re...

Background: The major limitation in human vision is refractive error. Auxiliary equipment and methods for these people are not always available. In addition, limited range of accommodation in adult people when switching from a far point to a near point is not simply possible. In this paper, we are looking for solutions to use the facilities of digital image processing and displaying to improve ...

The purpose of the study was to evaluate occurrence and range refractive errors in dogs different ages. A total 99 clinically healthy, mixed-breed mesocephalic were included divided into three age groups according current human/pet analogy chart: 40 adults (23 males, 17 females, 1–8 years old, 3–70 kg), 21 seniors (14 7 6–11 7–42 38 geriatrics (22 males, 16 8–13 5–45 kg). A...

BACKGROUND A significant increase in myopia among children and teenagers can be observed all over the world. Yet at the same time, there is still an insignificant number of studies concerning this health problem. The aim of this study was to assess the level of trait anxiety among myopic group of teenagers in comparison to teenagers with emmetropia, and to confirm whether the level of trait anx...

Clinical relevance: Investigation of refractive errors amongst Swedish schoolchildren will help identify risk factors associated with myopia development.Background: Genetic and hereditary aspects have been linked the development myopia. Nevertheless, in case ‘school myopia’ some authors suggest that environmental may affect gene expression, causing school to soar. Additional understanding about...
