Focusing of Light in the Eye01:16

Focusing of Light in the Eye

7.1K
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...

Glaucoma: Overview

1.6K
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...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

1.1K
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

1.6K
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Ophthalmic Drug Delivery Systems01:23

Ophthalmic Drug Delivery Systems

191
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...

Area of Science:

  • Ophthalmology
  • Refractive Surgery
  • Biomedical Engineering

Background:

  • Refractive surgery aims to correct vision errors through additive (lens implantation) or subtractive (corneal ablation) methods.
  • Phakic intraocular lenses (IOLs) are a key component of additive refractive procedures.
  • Understanding the types and outcomes of phakic IOLs is crucial for managing refractive errors.

Purpose of the Study:

  • To review the current status of phakic intraocular lens (IOL) implantation for refractive error correction.
  • To evaluate the safety, efficacy, predictability, and stability of phakic IOL procedures.
  • To identify potential complications associated with different types of phakic IOLs.

Main Methods:

  • Review of existing literature on phakic intraocular lens implantation.
  • Categorization of phakic IOLs based on fixation location (anterior chamber: angle-supported, iris-fixated; posterior chamber: sulcus-fixated).
  • Analysis of reported outcomes and complication rates.

Main Results:

  • Phakic IOL implantation is an effective, safe, predictable, and stable procedure for correcting higher refractive errors.
  • Complications are infrequent and vary based on lens location.
  • Anterior chamber lenses carry a risk of endothelial cell loss; posterior chamber lenses may lead to early cataract formation.

Conclusions:

  • Phakic IOL implantation represents a viable surgical option for refractive error correction.
  • Careful patient selection and understanding of location-specific risks are essential for successful outcomes.
  • Ongoing research and technological advancements continue to refine phakic IOL safety and efficacy.
