Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

557
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

669
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...

Focusing of Light in the Eye

3.2K
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

745
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...

Area of Science:

  • Ophthalmology
  • Biomedical Engineering
  • Optics

Background:

  • The Tecnis Eyhance intraocular lens (IOL) is an enhanced monofocal IOL designed for improved intermediate vision.
  • Limited long-term data exists for the Tecnis Eyhance IOL, necessitating further investigation beyond initial evaluations.

Purpose of the Study:

  • To assess the 5-year stability of visual, optical, and patient-reported outcomes after Tecnis Eyhance IOL implantation.
  • To evaluate the long-term effectiveness and safety of the Tecnis Eyhance IOL in a clinical setting.

Main Methods:

  • A 5-year follow-up of 18 patients (36 eyes) who received bilateral Tecnis Eyhance IOLs was conducted.
  • Visual acuity, optical quality, contrast sensitivity, effective lens position (ELP), and patient-reported outcomes were reassessed.
  • Halo size and incidence of posterior capsule opacification (PCO) were also evaluated.

Main Results:

  • Stable visual acuity across distance, intermediate, and near visual tasks was observed.
  • No significant changes in optical quality, contrast sensitivity, or effective lens position (ELP) were noted over 5 years.
  • High spectacle independence was maintained, with mild halo perception and a 5% rate of posterior capsule opacification (PCO).

Conclusions:

  • The Tecnis Eyhance IOL demonstrates long-term stability and effectiveness in visual and optical outcomes.
  • These findings support the continued use of the Tecnis Eyhance IOL as a reliable option for enhanced intermediate vision.
  • The IOL provides sustained functional benefits and patient satisfaction over a 5-year period.
