Summary
The duet procedure, combining monofocal and trifocal intraocular lenses, offers a safe and effective way to achieve reversible multifocality. This approach significantly improves uncorrected distance and near visual acuity in patients with mild co-existing eye conditions.
Area of Science:
- Ophthalmology
- Refractive Surgery
- Intraocular Lens Technology
Background:
- Cataract and refractive lens surgery aims to restore vision.
- Co-existing ocular pathologies can complicate surgical outcomes.
- The duet procedure involves simultaneous implantation of two intraocular lenses (IOLs).
Purpose of the Study:
- To evaluate the safety and efficacy of the duet procedure.
- To assess outcomes in eyes with co-existing pathologies undergoing cataract or refractive surgery.
- To determine the feasibility of reversible multifocality using this technique.
Main Methods:
- Retrospective case series of 80 eyes from 40 patients.
- Inclusion of patients with minor co-pathologies undergoing refractive lens exchange or cataract surgery.
- Preoperative and 3-month postoperative visual acuity and refractive error assessments.
Main Results:
- Significant improvement in monocular uncorrected distance visual acuity (UDVA) from 0.52 to 0.05 logMAR.
- Significant improvement in binocular uncorrected near visual acuity (UNVA) from 0.32 to -0.03 logMAR.
- The procedure demonstrated high safety and satisfactory visual and refractive outcomes.
Conclusions:
- The duet procedure provides reversible multifocality.
- It is a feasible option for eyes with mild co-existing pathologies.
- Satisfactory visual and refractive outcomes with high safety were achieved.

Angle Closure Glaucoma: Treatment
681
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
568
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.
