What is tecnis Eyhance IOL?
The TECNIS Eyhance, originally launched in Europe in February 2019, is a next-generation intraocular lens that goes beyond the expectations of the monofocal category to allow patients to experience high-quality vision at both intermediate and far distances.
What is Tecnis intraocular lens?
The TECNIS® multifocal IOL was designed using wavefront technology. This technology is used to correct optical aberrations (visual distortion) that can cause glare, halos, and a lesser visual quality. The TECNIS® is a diffractive lens with concentric rings of different power that provide vision at near and distance.
What is tecnis ZCB00?
Tecnis ZCB00 is a one-piece 6.0 mm biconvex hydrophobic acrylic lens with anterior aspheric surface that resulted in a negative SA of −0.27 μm and frosted continuous 360° posterior square edge.
What is SRK formula?
The SRK formula uses the following equation to calculate IOL power: P = A – BL – CK, where P is the implant power for emmetropia; L is the axial length (mm); K is the average keratometry (D); and A, B, and C are constants.
What is tecnis synergy?
The TECNIS Synergy™ Intraocular Lenses (IOLs) are artificial lenses implanted in the eyes of adults to correct vision after the natural lenses have been removed due to cataracts. Cataracts, or cloudiness of the natural lens, are often the result of aging, but can have other causes.
What is an Eyhance lens?
The Eyhance lens is a specially designed monofocal lens. Instead of having a uniform lens, it’s set to one refractive power on the lens’s edges and then transitions to a different refractive power in the middle of the lens. The result is improved distance vision, both far away and at a middle distance.
How does tecnis Symfony work?
How Does It Work? The Symfony IOL elongates the eye’s focus, rather than producing two distinct focal points. This elongated focus provides a more continuous spectrum of sharp vision from distance through intermediate and to near points.
Which lens is best for cataract surgery?
A monofocal lens is the most common type of lens used in cataract surgery, according to AAO. This type of lens is designed to give you crisp, clear vision at one particular distance. If you attempt to look at items that are closer or farther away than this set distance, those items may appear blurred.
What makes the Tecnis monofocal 1 piece IOL so good?
Give them the excellent outcomes they deserve with the sharpest vision, enhanced functionality and long-term sustainability from theTECNIS ® Monofocal 1-Piece IOL. The TECNIS ® Monofocal 1-Piece IOL is engineered for a higher standard of optical excellence so you can leave each patient with the sharp, high-quality vision they deserve.
When to use Johnson and Johnson IOL constants?
Johnson & Johnson Vision recommends that surgeons personalize their A-constant based on their surgical techniques and equipment, experience with the lens model and postoperative results. § IOL constants have been theoretically derived for contact ultrasound.
How does Tecnis Sym F ony TM IOL work?
By combining a unique diffractive pattern with achromatic technology, the TECNIS Sym f ony TM IOL delivers outstanding visual acuity over a continuous range of distances while maintaining high contrast performance. Deliver the visual quality that allows your patients with and without astigmatism to see clearly in any lighting condition.
Is the Tecnis toric IOL calculator based on a clinical study?
18. The TECNIS ® Toric IOL Calculator includes a feature that accounts for posterior corneal astigmatism (PCA). The PCA is based on an algorithm that combines published literature (Koch, et al., 2012) and a retrospective analysis of data from a TECNIS ® Toric multi-center clinical study.
