Clinical outcomes with a trifocal intraocular lens: a multicenter study
Journal of Refractive Surgery (Thorofare, N.J. : 1995)
|November 7, 2014
Summary
This study shows that the new trifocal intraocular lens (IOL) effectively restores distance, intermediate, and near vision. The FineVision IOL provides excellent visual outcomes for patients seeking pseudoaccommodation.
Area of Science:
- Ophthalmology
- Biomedical Engineering
- Optics
Background:
- Presbyopia correction remains a significant challenge in refractive surgery.
- Multifocal intraocular lenses (IOLs) aim to restore vision at multiple distances.
- Trifocal IOL designs offer a promising approach to pseudoaccommodation.
Purpose of the Study:
- To evaluate the clinical results and safety of a novel trifocal intraocular lens (IOL).
- To assess the efficacy of the FineVision trifocal IOL in achieving pseudoaccommodation.
- To determine the visual outcomes at distance, intermediate, and near after trifocal IOL implantation.
Main Methods:
- A pilot observational study involving 99 patients (198 eyes).
- Implantation of the FineVision trifocal IOL by 12 experienced surgeons.
- Postoperative assessment of uncorrected and corrected visual acuity at distance, intermediate, and near.
Main Results:
- Excellent uncorrected visual acuity achieved: distance (0.01 ± 0.06 logMAR), intermediate (0.08 ± 0.10 logMAR), and near (0.00 ± 0.04 logMAR).
- Postoperative spherical equivalent was 0.11 ± 0.36 D, indicating good refractive outcomes.
- High safety profile observed with minimal residual refractive error.
Conclusions:
- The trifocal FineVision IOL successfully restores functional vision at near, intermediate, and distance.
- This trifocal IOL design is effective for achieving pseudoaccommodation.
- The study supports the use of the FineVision IOL for presbyopia correction.

Open Angle Glaucoma: Treatment
1.1K
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.

Angle Closure Glaucoma: Treatment
1.7K
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...

Glaucoma: Overview
1.7K
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...
