Miniflex

 

MINIFLEX is the result of 25 years of experience accumulated in research, development, production of intraocular lenses and extensive discussions with renowned cataract surgery experts.

This intraocular lens incorporates revolutionary new concepts of material, optics, design, performance and clinical safety.

 

SUPERIOR PROTECTION AGAINST PCO

The ideal IOL should reduce the incidence of posterior capsule opacification.

Double Edge Square 360º

MINIFLEX is the first single piece collapsible IOL that has two square edges on its back, creating a double 360 ° lock against cell proliferation, even in the joint areas of the loops.

The compression of the lugs causes a posterior displacement of the optic, providing full contact between the IOL and the posterior capsule, eliminating voids and favoring the blocking action of the square edges.

EASE AND PRACTICE

The ideal IOL should be easy to use and not require major changes or adaptations in surgical technique.

Disposable Visco-Injector

MINIFLEX is supplied with an injection kit consisting of a cartridge and a single-use visco-injector. The unique visco-injection system prevents IOL contact with the injector piston, avoiding damage to the implant and eliminating problems common to traditional injectors, such as incarceration or amputation of the handles. The system is easy to assemble and because it is disposable it is much more practical and safe.

Accessories for MICS Coaxial

  • Nano-tips 21GA. Special phaco and infusion gloves for MICS Coaxial and compatible with phacoemulsifiers of all makes and models.
  • Disposable scalpel for incision clear cornea 1.8mm and 2.2mm.

 

MATERIAL

The ideal material should protect the retina and combine the positive characteristics of hydrophobic and hydrophilic acrylics.

Flexacryl® Hybrid Acrylic

Flexacryl is a unique acrylic copolymer that combines hydrophobic and hydrophilic monomers with a long history of use, safety and efficacy for intraocular application.

UV Filter and New Natural Yellow® Chromophore

The use of yellow chromophores in some materials in which blue light is blocked under the argument of protecting the retina causes adverse effects such as loss of contrast sensitivity and dysfunctions of the cicardial physiology that regulates the biological clock. Scientific studies have shown that the natural progressive yellowing of the human lens and the consequent reduction in the absorption of blue light is related to the high incidence of sleep disorders and depression in the elderly.

The new and unique Natural Yellow chromophore used in MINIFLEX is a compound of hydroxyquinurin, the natural yellow chromophore present in the human lens. This chromophore was synthesized and incorporated into the material to give MINIFLEX a light absorption similar to that of a 20-year-old young human lens, UVA blocker up to 400 nm, powerful violet filter and discreet dark blue filter.

The use of the natural crystalline chromophore, selected by nature over hundreds of thousands of years of evolution of the human species, is the most physiological solution for filtering potentially harmful light rays and allowing the passage of the healthy blue spectrum, protecting the retina, sensitivity to contrast and not interfering with the patient’s biological rhythm.

 

 

OPTICAL DESIGN

The ideal optics should not induce positive or negative spherical aberration.

Spherical Aberration-Free Aspheric Optics

MINIFLEX has an aspherical parabolic optical design designed and optimized by modern ray tracing software. Unlike other aspherical IOLs that induce spherical negative aberration, MINIFLEX is free of spherical aberration, providing greater depth of focus and not compromising visual acuity and contrast sensitivity in case the implant undergoes some decentration.

DESIGNED FOR MICS

The size of the incision should be as small as possible.

Injection System 1.8mm

MINIFLEX usher in a new era for cataract surgery by microincision. The high pseudoplasticity of the material and the unique viscoinjection system allow the implant to be incised smaller than the other IOLs without sacrificing the optical diameter. MINIFLEX can be implanted by means of a 1.8mm incision with a mouth-to-mouth injection technique, or 2.2mm with introduction of the cartridge into the anterior chamber.

 

LONG TERM STABILITY

The ideal design should ensure the long-term stability of the implant.

Self Doubling Handles

MINIFLEX’s new double-loop design provides equalized compression force as the capsular bag undergoes contraction.

Haptic Angulation Step

  • Keeps the lugs parallel to the plane of the optic part even when flexed.
  • Prevents torseness and tilt of the optics.
  • Model validated according to ISO-11979 requirements for optical torsion (<5º).

 

Unique Mechanical Cushion Cavity

  • It acts as a damping element of the mechanical stress generated by the compression of the lugs, which is not transmitted to the optical part.
  • It isolates the optics of the mechanical forces of the haptic compression even with the contraction of the capsular bag, avoiding the decentration of the implant.
  • Concept validated by advanced finite element analysis software.

Wide Capular Contact Arc

The MINIFLEX haptic design guarantees a large contact area between the IOL and the capsular bag (> 80º), providing excellent balance and stability.

Mediflex

MEDIFLEX is a state-of-the-art hydrophobic acrylic folding intraocular lens and innovative features to ensure excellent performance and safety.

ADVANCED DISCHARGEABLE INJECTION SYSTEM

Each MEDIFLEX comes with an advanced injection system consisting of a disposable cartridge and injector. The injector silicone plunger provides atraumatic, quick and safe injection without damaging the implant. The system is easy to assemble, and being of single use is more practical and safe than reusable injectors.

 

Quality Mediphacos

MEDIFLEX is manufactured in production certified by the international standards ISO-9001, ISO-13485, Medical Directive of the European Community and Good Manufacturing Practices and Control (Anvisa). All Mediphacos products are complemented by excellent after-sales service and after-sales service.

 

HYDROPHOBIC ACRYLIC MATERIAL

Mediflex is manufactured from a unique hydrophobic acrylic polymer of excellent biocompatibility:

Refractive Index = 1.48

IR lower than other hydrophobic acrylics
eliminating visual symptoms related to high refractive indexes (> 1.5), eliminating internal reflections, mirror effect and pseudophakic dyspho- pps that can produce glare and glare. (1)

Shore A hardness index = 91

Higher than other hydrophobic acrylics, making the material more rigid in the intraocular environment and contributing to greater stability of the implant.

Minor Incidence of “Glistenings”

Because of its unique, more uniform polymerization process, lower hydration index and polymer stability at different temperatures, the formation and severity of glistenings (aqueous micro-vacuoles) in the MEDIFLEX material is 92% lower than in competing materials, avoiding side effects such as glare and loss of contrast sensitivity, which may require the IOL explant.

6MM ASYMMETRIC BICONVEX OPTICS

The optical design of Mediflex has been designed through advanced ray tracing programs to produce superior optical resolution and reduce spherical aberration, generating excellent image quality.

Mediflex provides greater depth of focus compared to other monofocal acrylic lenses, reducing the dependence of glasses for intermediate vision. The optical properties meet or exceed the requirements of international standard ISO-119792.

Square edges 360º

Unlike other square posterior edge folding IOLs, Mediflex has a 360º square posterior border, including the area of ​​the junction of the lugs, providing an effective mechanical barrier against cell proliferation and reducing the incidence of posterior capsule opacification. (REF OCP)

StableMax Haptic Drawing

The unique StableMax design used in Mediflex was developed from advanced finite element analyzes and exhaustive mechanical and structural tests to ensure excellent implant stability in various diameter capsule bags.

The wide arc of contact between the Mediflex loops and the equatorial fornix of the capsular bag favors the stability of the lens, avoiding the decentration, tilting and rotation of the IOL even after the capsular contraction.

The 13.0mm diameter of the handles allows secure attachment of the implant to the capsular bag or the ciliary groove. The discreet haptic angulation of 5º does not allow the anterior displacement of the lens, avoiding iriana complications and increasing the contact between the IOL and the posterior capsule, favoring the action of the square edges.
