Topography-Guided Customized PRK Versus Q-value Adjusted PRK in Correction of Myopia With or Without Astigmatism

2017-09-26 04:38:21 | BioPortfolio

Summary

This study will include patients who will undergo PRK in both eyes, for each patient each eye will be randomly allocated to one of 2 procedures:

topography-guided ablation in one eye (group I) and Q-factor customized ablation in the other eye (group II).

Alcon/Wavelight Light Laser Technolo¬gie (GmbH, Erlangen, Germany) will be used for photoablation.

The wavelight Topolyzer (Wavelight AG, Erlan¬gen, Germany) will be used before and 1, 3 and 6 months after PRK. Refrac¬tive visual outcomes and corneal aberration changes will be compared between the two treatment modalities.

The Use of Atropine 0.01% in the Prevention and Control of Myopia (ATOM3)

Study of low dose atropine in preventing the onset and progression of myopia in high risk children with pre-myopia or low-myopia.

Cambridge Anti-Myopia Trial: Accommodation Training and Aberration Control in Myopia Development

We have identified focussing problems related to myopia getting worse. Our trial uses optical and orthoptic interventions that correct the focussing problems to see if this retards myopia ...

Eye Drops Study for Myopia Control in Schoolchildren

The myopia prevalence in schoolchildren is high in Taiwan. The myopia progression is fast in children and often associated high myopia in later life. This prospective and randomized study ...

Does Undercorrection of Myopia Retard Myopia Progression Among Kindergarten Children?

The purpose of this study is to find out if undercorrection of myopia slow down the progression of myopia in kindergarten children.

Topical Application of Low-concentration (0.01%) Atropine on the Human Eye With Fast and Slow Myopia Progression Rate

Our project is a 24-month longitudinal randomized controlled trial that aims to investigate the myopia development after topical application of 0.01% atropine in children with either fast ...

IMI - Myopia Control Reports Overview and Introduction.

With the growing prevalence of myopia, already at epidemic levels in some countries, there is an urgent need for new management approaches. However, with the increasing number of research publications...

Controlling Progression of Myopia: Optical and Pharmaceutical Strategies.

The burden associated with the rising prevalence of myopia and high myopia, and the associated vision impairment and sight-threatening complications, has triggered the need to evaluate strategies to c...

Myopia is associated with education: Results from NHANES 1999-2008.

Myopia is increasing worldwide and possibly linked to education. In this study, we analyse the association of myopia and education in the U.S. and investigate its age-dependency.

Myopia: is the nature-nurture debate finally over?

In the nineteenth century, the prevalence of myopia began to rise, and Cohn stressed the role of education. Later, based on twin studies, Sorsby argued that refraction was almost totally genetically d...

Medical and Biotech [MESH] Definitions

Excessive axial myopia associated with complications (especially posterior staphyloma and CHOROIDAL NEOVASCULARIZATION) that can lead to BLINDNESS.

Plastic surgery of the SCLERA. This procedure is used frequently to prevent blindness and poor vision in patients, especially children, with MYOPIA.

A type of refractive surgery of the CORNEA to correct MYOPIA and ASTIGMATISM. An EXCIMER LASER is used directly on the surface of the EYE to remove some of the CORNEAL EPITHELIUM thus reshaping the anterior curvature of the cornea.

Detachment of the corpus vitreum (VITREOUS BODY) from its normal attachments, especially the retina, due to shrinkage from degenerative or inflammatory conditions, trauma, myopia, or senility.

A refractive error in which rays of light entering the EYE parallel to the optic axis are brought to a focus in front of the RETINA when accommodation (ACCOMMODATION, OCULAR) is relaxed. This results from an overly curved CORNEA or from the eyeball being too long from front to back. It is also called nearsightedness.
