Focusing of Light in the Eye01:16

Focusing of Light in the Eye

4.7K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Confocal Fluorescence Microscopy01:16

Confocal Fluorescence Microscopy

19.6K
Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...

Area of Science:

  • Ophthalmology
  • Optometry
  • Biomedical Engineering

Background:

  • Presbyopia affects a significant portion of the adult population, increasing the demand for vision correction solutions.
  • Multifocal contact lenses offer a non-surgical option for presbyopia correction, addressing a growing market need.
  • Understanding the publication landscape is crucial for identifying research trends and future directions in multifocal contact lens development.

Purpose of the Study:

  • To conduct a bibliometric analysis of scientific publications concerning multifocal contact lenses.
  • To assess the growth trends, productivity, and key journals in the field of multifocal contact lens research.
  • To identify leading countries contributing to scientific advancements in multifocal contact lens technology.

Main Methods:

  • Utilized the SCOPUS database, searching for "multifocal contact lens," "bifocal contact lenses," "progressive contact lenses," and "presbyopia contact lenses."
  • Applied bibliometric indicators including doubling time, annual growth rate, Price's transience index, Lotka's law, and Bradford's zones.
  • Analyzed publication data from 1960 to 2019.

Main Results:

  • A total of 346 articles were published between 1960 and 2019.
  • Publication growth demonstrated an exponential trend (R² = 0.53) with a doubling time of 13.2 years.
  • The core journals identified were 'Optometry and Vision Science' and 'Eye and Contact Lens,' with an average of 2.06 authors per article.

Conclusions:

  • Research on multifocal contact lenses exhibits exponential growth, indicating continued scientific interest and development.
  • The field has not reached a saturation point, suggesting ongoing innovation and publication output.
  • The United States and Australia are the leading nations in scientific production within the multifocal contact lens domain.
