Some visual effects may be expected due to the superposition of focused and unfocused multiple images. These may include some perceptions of halos, radial lines around point sources of light starbursts under nighttime conditions, or glare, as well as other visual symptoms. As with other multifocal IOLs, there is a possibility that visual symptoms may be significant enough that the patient will request explant of the multifocal IOL.
A reduction in contrast sensitivity as compared to that expected with a monofocal IOL may be experienced by some patients and may be more prevalent in low lighting conditions. Therefore, patients implanted with multifocal IOLs should exercise caution when driving at night or in poor visibility conditions. Patients should be advised that unexpected outcomes could lead to continued spectacle dependence or the need for secondary surgical intervention e.
As with other multifocal IOLs, patients may need glasses when reading small print or looking at small objects. Prior to surgery, physicians should provide prospective patients with a copy of the Patient Information Brochure available from Alcon informing them of possible risks and benefits associated with the IOLs.
Alcon Data on File, Proprietary blue light filtering chromophore filters light in a manner that approximates the crystalline lens in the nm blue light wavelength range. The biconvex optic with supporting haptics consists of a high refractive index soft acrylic material capable of being folded prior to insertion. The aberration-free lens has uniform center-to-edge power, producing a more natural range of vision with excellent contrast sensitivity and minimized issues with halos and glare.
The enVista intraocular lens is a hydrophobic, single-piece ultra-violet absorbing posterior chamber intraocular lens designed to be free of spherical aberration. Glistenings, caused by fluid-filled microvacuoles that can form within an IOL, are abated by hydrating the lens to equilibrium water content and packaging the lens in 0. Step-vaulted haptics vault the optic posteriorly for direct contact with the capsular bag. The Trulign Toric IOL is a toric modification of the company's Crystalens AO, with the addition of a toric optic on the posterior surface and two axial orientation markings on the anterior surface.
The Akreos MICS model ML lens combines the benefits of an aberration-free aspheric acrylic lens with the material and design characteristics that allow it to be inserted into a true 1. The Akreos AO model AO60 lens combines the benefits of an aberration-free aspheric acrylic lens with the material and design characteristics that allow it to be inserted into a true 1.
The four point haptic design of the Akreos AO features looped ends. The 3-piece SofPort AO is neutral to the induction of positive or negative spherical aberrations. It has prolate anterior and posterior surfaces and uniform thickness and refractive power from the lens' center to its edge. The Aspheric Balanced Curve ABC was designed to provide a sharp visual image while the square edge of the lens helps to minimize posterior capsule opacification.
The Optimized Aspheric IOL blue light absorbing IOL was designed to provide negative spherical aberration along with a unique central power distribution that maintains image quality with misalignment.
The unique one-piece, two material design of this intraocular lens provides proper centration and better stability in the eye for greater image sharpness.
The yellow blue light filtering optic features an aspheric design. The clear ultraviolet absorbing optic features an aspheric design. The Sensar IOL is a 1-piece lens made from a hydrophobic material not associated with glistenings.
The lens reduces the transmission of UV light while still allowing healthy blue light. The edge is designed with a ProTEC frosting to reduce potential edge glare effects and ?
According to data on file with the company, the lens has reduced chromatic aberration and spherical aberration is corrected to essentially zero. The lens is designed to provide improved uncorrected distance vision, reduction in residual refractive cylinder, and increased spectacle independence for distance vision.
The lens was designed with a proprietary achromatic diffractive surface to correct chromatic aberration and a unique echelette feature to extend the range of vision, including far, intermediate, and near, while maintaining the corneal spherical aberration compensation. The lenses incorporate a diffractive multifocal optic pattern designed to provide near, intermediate and distance vision and thereby reduce spectacle dependency.
Gemini Refractive Capsule. The capsule contains a true refractive lens and uniquely maintains an open space in the capsular bag for theorhetical incorporation of drug delivery, biometric sensors, or additional refractive lens platforms.
The design borrows from current lens designs only with regard to the advanced optics and biocompatible materials from traditional IOLs. Finevision Trifocal Optic Pod F. It is designed so as to reduce the loss of light energy resulting from any diffractive system.
Finevision Trifocal Optic Micro F. Ankoris Monofocal Toric Optic. The double C-loop haptics provide optimal rotational stability and have ridged indentations called WaveTech to reduce the risk of stickiness between the haptics and optic during injection. FluidVision Accommodating Intraocular Lens. The FluidVision AIOL provides accommodation by moving a tiny amount of fluid inside the lens in response to the natural muscle forces in the eye.
The Company has shown in clinical trials that it can deliver clear vision at all distances. The FluidVision lens is an investigational device that is not available for sale. The design offers rotational and centrational stability, excellent fixation in the capsular bag, and has an aspheric anterior surface. RayOne Aspheric lenses offer the largest selection fully preloaded power ranges.
The design offers rotational and centrational stability and excellent fixation in the capsular bag. C-flex Aspheric Monofocal. Superflex Aspheric Monofocal. The C-flex Aspheric model C is a hydrophilic acrylic monofocal IOL with a degree enhanced square edge and aberration-neutral optic technology. M-flex T Multifocal Toric. M-flex T Multifocal Toric IOL models F and F offers all the benefits of the M-flex and effectively corrects corneal astigmatism with a range of cylinder power options from 1 to 6 diopers.
Sulcoflex Multifocal Toric. Sulcoflex Multifocal Toric lens model Z is a hydrophilic acrylic supplementary IOL with a unique posterior concave surface designed to minimize the possibility of interaction with the primary IOL. Sulcoflex Multifocal lens model F is a hydrophilic acrylic supplementary IOL with a unique posterior concave surface designed to minimize the possibility of interaction with the primary IOL.
Closed looped haptic configuration was designed to offer excellent centration with rotational, torsional and directional stability. The T-flex Aspheric Toric lens models T and T features a closed looped haptic configuration progressively absorbs forces generated within the contracting capsular bag to offer excellent centration with rotational, torsional and directional stability.
Sulcoflex Aspheric model L is a hydrophilic acrylic supplementary IOL with a unique posterior concave surface designed to minimize the possibility of interaction with the primary IOL. This lens is indicated for the correction of any residual pseudophakic corneal astigmatism. Biocompatible materials called macromers incorporated into the makeup of the IOL undergo a chemical change known as photopolymerization in response to ultraviolet light of a certain wavelength.
Using a proprietary light treatment surgeons can precisely reshape the lens based on the exact amount of visual correction and optimization needed to achieve desired vision after implantation. The Rayner C Aspheric lens is an aberration neutral lens made from a homogeneous material not associated with glistenings. It also promotes rapid wound healing and accelerated postoperative regeneration.
