More Than Expected

Prevalence of astigmatism is much more than expected among cataract patients. High prevalence of corneal astigmatism has been reported in many different articles. After toric implantation, residual postoperative corneal astigmatism of 0.75D or lower may improve uncorrected visual acuity and reduce symptomatic blur, ghosting of images and halos1.

40% of Cataract Patients Exhibit ≥1.0 D Astigmatism
The study published by Ferrer-Blasco T et al. in  2009, consisting of 4540 patients with cataract showed corneal astigmatism to be prevalent in 87% of patients.
Clear Vision for Astigmatic Patients

You can make more patients happy. Patients will begin enjoyable life after surgery with clear vision and spectacle independence. AcrivaUD Reviol Tri-ED Toric has the largest diopter range in the astigmatism correcting IOLs which is defining as Custom Made Perfection. Spherical power starts from 0.00D to 32.00D and cylinder power range is available up to 10.00D with half diopter increments.

Seamless Continuous Vision

Our new approach to diffractive trifocal technology brings seamless continous vision to the presbyopia treatment in cataract surgery. AcrivaUD Reviol  Tri-ED Toric is the Trifocal Optic combined with Enhanced Depth of Focus vision. Innovative zone establishment displays excellent MTF values even between the intermediate zones. AcrivaUD Reviol  Tri-ED Toric showed superior MTF results according to comparative analyses against to current trifocal IOLs1. The more resolution is the happier patient is. 

MTF, Modular Transfer Function, is the measurement of an optical system refers the amount of contrast which is passed through optic in determined spatial frequency. Defining the criteria of “Good” the optical system has been determined by The International Organization for Standardization (ISO) standard 11979-22. MTF test results of AcrivaUD Reviol  Tri-ED Toric will bring seamless continuous vision to the patient.    


Minimum SIA, Excellent Stability in MICS Design

Larger incision causes surgically induced astigmatism and directly affects post-operative outcomes. AcrivaUD Reviol Tri-ED Toric plate haptic is the best choice as it enables implantation through sub 2.0mm incision. It can then minimize Surgically Induced Astigmatism and stays in the capsular bag without any rotation.

Alignment of AcrivaUD Reviol Tri-ED Toric is possible both clockwise and anticlockwise during the operation. It additionally grants excellent rotational stability as the toric IOL holds on to the posterior capsular bag on four points.

Preoperative Diagnosis 

Amount and Axis of Astigmatism

Successful toric implantation starts with precise examination and evaluation of the amount and axis of corneal astigmatism. Selection of an ideal patient for toric application keratometry, biometry, pupillometry, aberrometry, videokeratoskopy or any other devices are recommended to use as a preoperative diagnostic evolution.

Measurements should be repeated under suitable conditions if big differences are found among different methods. Determine the axis of astigmatism is equally important with its amount which involves directly outcomes after implantation. Regular astigmatism should be assured by checking topographic map of the cornea. 

Inclusion Criteria

Optimum post-operative results are based on correct patient selection and recommend inclusion criteria should be followed in pre-operative toric surgery plan. Total astigmatism of the eye is the value measured in routine clinical practice which includes both cornea dependent external astigmatism and neutral lens dependent internal astigmatism. Only external astigmatism must be kept consideration in toric IOL calculation since lens is removed during surgery4.

Recent studies have shown the importance of considering the posterior corneal surface when determining total corneal astigmatism and planning astigmatism correction. The posterior cornea acts as a minus lens and it should be evaluated during pre-operative planning5,6.

Optimum Filtration Range - Balanced Photoprotection of UVA and Violet Spectrum

AcrivaUD Reviol Tri-ED Toric provides excellent photoprotection from potential damage of the UVA and violet spectrum without blocking blue light. AcrivaUD  Reviol Tri-ED Toric ensures 95% blue light transmission at 480nm, whichis known as critical in controlling the circadian rhythm.

The chromophore used in AcrivaUD Reviol Tri-ED Toric material has a similar chemical structure with the chromophore naturally present in the human lens, thus giving a transmission structure comparable to the one of a young healthy eye.

Importance of Blue Light

Blue light plays a crucial role in controlling the circadian rhythm and endogenous melatonin secretion. Disorganization of the circadian rhythm is more common in older adults and people with insomnia, depression and dementia. Blue-blocking IOLs, which contain synthetic dye, filter up to 500 nm causes excessive filtering of blue light.

Natural Chromophore - Same Transmission Properties than Natural Lens

AcrivaUD Reviol Tri-ED Toric contains 3-hydroxykynurenine, which is similar to the chromophore present in the human natural lens.

The chromophore structure of AcrivaUD Reviol Tri-ED Toric possesses the same transmission as a human natural crystalline lens with a good protection of the macula against UV-A and blue light thanks to the absorption curve which mimics the human crystalline lens, preserving the natural color perception and contrast sensitivity.

Ideal Concentration - Improved Contrast Sensitivity

The chromophore concentration of AcrivaUD Reviol Tri-ED Toric is 0,02%. It has a clearer color in comparison to IOLs with higher concentrations of chromophores. Low concentration of AcrivaUD Reviol Tri-ED Toric does not influence color perception of the patient.Natural chromophore and its lower concentration provide a higher contrast sensitivity under low light conditions.

Maximum Light Transfer

The reliable performance of Reviol’s Active-Diffractive optic has been proven in over forty countries with thousands of implantations. AcrivaUD Reviol  Tri-ED Toric optic provides maximum light transmission to the retina with excellent light distribution.  Effective light transmittance reaches up to 89.1% on average. 

Diffractive multifocal IOLs separate light into near to distance by creating a phase difference. AcrivaUD Reviol  Tri-ED Toric was designed with unique height, width and interval of its rings at different number on the surface. The distribution rings of all surface makes the optic fully pupil independent. 

Optimum Light Distrubition

Light is distributed by 44% far, 28% intermediate and 28% near six mm aperture pupil size in AcrivaUD Reviol  Tri-ED Toric. Balanced light distribution provides increased contrast sensitivity even at mesopic light condition.

The success of optical performance in multifocal intraocular lenses relies on determining optimum diffraction efficiency as a percentage of light into diffraction orders. Unique diffractive zones of AcrivaUD Reviol  Tri-ED Toric split light through focal path without compromising of light loss directed to outside of far and near foci.

Appropriate Disparity

AcrivaUD Reviol Tri-ED Toric is combined with 3.0D near addition and 1.5D intermediate addition for creating a revolutionary three-phase difference. Adequate and appropriate disparity selected in AcrivaUD Reviol Tri-ED Toric between near and intermediate focus excludes overlapping problems and creates sharp vision at all distances.

Diffraction efficiency is directly correlated with imaging characteristics and overall image performance of a multifocal optic. Focal overlapping between light centralization in different  points plays a negative role in image quality and photopic phenomena. The detached focal zones of AcrivaUD Reviol  Tri-ED Toric optic design have been optimized according to test results of geometrical model. 

Enhanced Visual Acuity for All Distances

Clinical findings reported that AcrivaUD Reviol Tri-ED Toric presents significant improvements in UDVA, UIVA and UNVA. Superior intermediate visual acuities were observed in binocular defocus curve in comparison with bi-focal multifocal IOLs.

Post-operative refractive outcomes were within the range of -0.75 to +0.25 diopter. No severe glare/halo problems have been reported. All contrast sensitivity results were at the range of 3-12 spatial frequencies measurements and 92% of patients reported spectacle independence in the questio

Advanced Vision of Aspheric Design

Ultra Definition optic design corrects spherical aberrations coming from both cornea and IOL. However, AcrivaUD Reviol Tri-ED Toric IOLs have a slight negative asphericity, which maintains part of the positive aberration of the cornea, helping patient to keep better depth of focus.


Advantage of Ultra Definition Design

  • Improved contrast under low light condition
  • Preserved depth of focus
  • Less sensitive to decentration

Real PCO Barrier

The innovative edge design tends to greatly reduce PCO risks by making a geometric and mechanical barrier against cells proliferation. The edge design produces thinner lenses for equivalent power than other competitors.

Exceptional Design

All Square 360° enhanced edge and premium material form a dual barrier against the risk of Posterior Capsule Opacification after implantation. Recent studies have shown that square edge on posterior surface of the optic is the most important IOL-related factor against PCO formation.
