Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

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...
Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

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...
Focusing of Light in the Eye01:16

Focusing 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...
Glaucoma: Overview01:25

Glaucoma: 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...
Ophthalmic Drug Delivery Systems01:23

Ophthalmic 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...

Area of Science:

  • Ophthalmology
  • Optics
  • Biomedical Engineering

Background:

  • The increasing variety of intraocular lens (IOL) designs for presbyopia management presents a challenge for optimal patient selection.
  • Understanding the optical properties and clinical performance of different IOLs is crucial for successful outcomes.

Purpose of the Study:

  • To provide an updated review of current monofocal plus, extended depth of focus (EDoF), and trifocal IOLs.
  • To summarize their optical characteristics, laboratory findings, and clinical results, including visual acuity and side effects.

Main Methods:

  • A comprehensive literature search was performed using PubMed.
  • Studies focusing on monofocal plus, EDoF, and trifocal IOLs were identified, emphasizing optical properties, visual acuity, and photic phenomena.

Main Results:

  • Monofocal plus IOLs enhance depth of field and broaden the defocus curve compared to standard monofocal lenses.
  • Extended depth of focus (EDoF) IOLs improve intermediate vision; diffractive EDoF models offer greater depth but higher dysphotopsia risk.
  • Trifocal IOLs provide excellent visual acuity at near, intermediate, and distance foci. Customized patient needs can be met with various fixation and binocular strategies.

Conclusions:

  • Current clinical and optical data support selecting IOLs based on individual patient needs for presbyopia.
  • Further research, including large-scale prospective, randomized, controlled, and masked studies, is needed for understudied or new IOL models to enhance patient decision-making.
