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...
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...
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...

Area of Science:

  • Ophthalmology
  • Surgical Technology
  • Cataract Surgery

Background:

  • Phacoemulsification is a standard cataract surgery technique.
  • Continuous innovation in surgical systems aims to improve patient outcomes.
  • The EVA NEXUS represents a novel advancement in phacoemulsification technology.

Purpose of the Study:

  • To compare the novel EVA NEXUS phacoemulsification system against the established EVA system.
  • To evaluate differences in surgical efficiency, intraoperative safety, and postoperative inflammatory activity.
  • To assess visual and refractive outcomes following cataract surgery with both systems.

Main Methods:

  • A comparative study involving 20 patients (40 eyes) undergoing bilateral cataract surgery.
  • One eye received the EVA system (control), the other the EVA NEXUS system (intervention).
  • Prostaglandin E2 levels, anterior chamber flare, endothelial cell count, and visual/refractive outcomes were measured.

Main Results:

  • No significant differences were found in intraoperative safety parameters (effective phacoemulsification time, fluidics, total surgery time).
  • Postoperative prostaglandin E2 levels, anterior chamber flare, and endothelial cell loss were numerically lower in the EVA NEXUS group, but not statistically significant.
  • Both systems yielded similar best-corrected visual acuity and refractive outcomes.

Conclusions:

  • Both EVA and EVA NEXUS systems offer high safety and efficiency in cataract surgery.
  • Clinical outcomes, safety parameters, and inflammatory markers were comparable between the two systems.
  • The EVA NEXUS system shows a trend towards reduced postoperative inflammation, warranting further investigation.
