Summary
DisCoVisc, a new dual-property viscoelastic, offers better surgical visualization and anterior chamber maintenance during cataract surgery compared to Healon. Healon, however, was easier to aspirate post-procedure.
Area of Science:
- Ophthalmology
- Surgical Innovation
Background:
- Cataract surgery requires effective viscoelastic devices to maintain anterior chamber integrity.
- Current practices may involve using multiple viscoelastics for different surgical stages.
Purpose of the Study:
- To compare the intraoperative performance of DisCoVisc and Healon as viscoelastics in cataract surgery.
- To evaluate the cohesive and dispersive properties of DisCoVisc versus the cohesive properties of Healon.
Main Methods:
- Prospective randomized study of 35 patients undergoing phacoemulsification and intraocular lens implantation.
- Patients were assigned to receive either Healon (Group A, n=17) or DisCoVisc (Group B, n=18).
- Surgeons completed questionnaires detailing viscoelastic behavior during surgical phases.
Main Results:
- DisCoVisc demonstrated both cohesive and dispersive properties throughout capsulorrhexis, phacoemulsification, and aspiration.
- Healon exhibited cohesive properties during all surgical stages.
- DisCoVisc provided superior visualization, transparency, and capsular bag stability compared to Healon.
- Healon facilitated easier viscoelastic aspiration.
Conclusions:
- DisCoVisc offers a novel solution with combined cohesive and dispersive properties, potentially simplifying cataract surgery.
- DisCoVisc enhances intraoperative visualization and anterior chamber maintenance more effectively than Healon.
- Healon's cohesive nature simplifies its removal, presenting a trade-off in performance characteristics.

01:27Open 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.

01:28Angle 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...
