|October 1, 1980
Summary
This study introduces mathematical formulas to estimate tear volume changes under flexible contact lenses. The method uses power variations but requires careful consideration of its approximate nature due to assumptions.
Area of Science:
- Ophthalmology
- Biomedical Engineering
- Optometry
Background:
- Understanding tear dynamics is crucial for contact lens comfort and ocular health.
- Flexible contact lenses are widely used, but their impact on tear exchange is not fully quantified.
Purpose of the Study:
- To develop and present a mathematical method for inferring volumetric tear exchange.
- To utilize in situ power changes of flexible contact lenses for this estimation.
Main Methods:
- Mathematical formulas derived from radial power changes.
- In situ measurements of flexible contact lens power variations.
Main Results:
- A method to infer volumetric tear exchange from contact lens power changes.
- The calculations are based on changes observed along the lens radius.
Conclusions:
- The developed mathematical approach offers an inference of tear exchange under flexible contact lenses.
- The approximate nature of these calculations necessitates awareness of underlying assumptions.

01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
01:17Accessory Structures of the Eye
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...
01:16Focusing of Light in the Eye
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...
01:23Ophthalmic Drug Delivery Systems
Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...
