Angle Closure Glaucoma: Treatment

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: Treatment

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 Eye

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...

Summary

The Clareon Vivity intraocular lens (IOL) showed better intermediate vision and fewer visual disturbances than the TECNIS PureSee IOL. Both extended depth-of-focus (EDoF) IOLs offer high patient satisfaction.

Background:

Extended depth-of-focus (EDoF) intraocular lenses (IOLs) aim to provide a continuous range of vision.
Comparing the visual performance of different EDoF IOL models is crucial for clinical decision-making.

Purpose of the Study:

To compare the postoperative visual performance of two non-diffractive EDoF IOLs: TECNIS PureSee and Clareon Vivity.
To evaluate visual acuity, contrast sensitivity, and patient-reported outcomes between the two IOLs.

Main Methods:

A retrospective comparative study involving 102 eyes (51 per group) implanted with either PureSee or Vivity IOL.
Assessment of visual acuity at multiple distances, defocus curves, and contrast sensitivity (photopic and mesopic) at 2 months postoperatively.
Evaluation of patient satisfaction and visual disturbances.

Main Results:

Both IOLs provided comparable distance and near visual acuity.
The Vivity IOL demonstrated significantly better intermediate visual acuity (P = 0.045).
The PureSee IOL showed significantly higher contrast sensitivity at high spatial frequencies (P = 0.038).
High and comparable patient satisfaction and spectacle independence were reported for both groups.
The Vivity group trended towards fewer reports of glare and halo.

Conclusions:

The Clareon Vivity IOL offers superior intermediate vision and reduced photic phenomena compared to the TECNIS PureSee IOL.
These findings aid in selecting the appropriate EDoF IOL based on individual patient visual needs and lifestyle.
