باسلام
جراح برای تعویض لنز (بدلیل عارضه آب مروارید) از این لنز استفاده کرده
میخواستم بدونم کیفیتش چجوریاست؟؟

MINIFLEX is result of Mediphacos’ 25 years of expertise in intraocular lens research,
development, design and manufacturing.This innovative intraocular lens was developed following extensive discussions with world-renowned cataract surgeons, incorporating new and unique concepts in its material, optics, design and clinical performance.SUPERIOR PROTECTION AGAINST PCO
“The ideal IOL must reduce PCO rates.”Double Square Edge 360º
MINIFLEX is the first one-piece foldable IOL to incorporate
two posterior square edges of 360º, creating a double
barrier against LEC proliferation, even on the haptic-optic junction areas.The haptic compression generates a posterior movement of the optic, increasing the contact between the IOL and the posterior capsule and improving the protection efficiency of the square edges.EASY AND PRACTICAL
“The ideal IOL must be easy to use and be compatible with the surgeon’s preferred technique.”Disposable Injection System Included
MINIFLEX is supplied with a safe and convenient disposable injection set. This advanced system avoids direct contact between the IOL and the injection plunger, eliminating problems such as haptic trapping and tearing.MATERIAL
“The ideal IOL material must provide retinal protection and combine positive features of hydrophobic and hydrophilic acrylics.”Flexacryl Hybrid Acrylic®
Flexacryl is a unique copolymer that combines hydrophobic and hydrophilic monomers with long and successful track record of intraocular biocompatibility:UV BLOCKER AND NEW NATURAL YELLOW® CHROMOPHORE
The use of blue-blocking chromophores in some IOL materials may lead to undesirable side-effects such as loss of contrast sensitivity and impact the cicardian physiology which regulates biorythms. Strong scientific evidence documents that the progressive yellowing of the aging human lens is related to the high incidence of sleep disorders and depression in the elderly.
Miniflex’s new Natural Yellow® chromophore is a hydroxykynurenine compound, the very same yellow chromophore that occurs naturally in the human lens. Using the same chromophore selected by nature through hundreds of thousands of years of evolution of the human species is the most physiologic solution to filter out potentially harmful wavelengths while still allowing healthy blue spectrum light in, thus protecting the retina, enhancing contrast sensitivity and not interfering with the patient’s biologic cycles.

OPTIC DESIGN
“Ideal optics should not introduce positive or negative spherical aberrations.”Aberration-Free Aspheric Optics
MINIFLEX features a unique aspheric optic design optimized by state-of-the-art ray tracing software. Unlike other aspheric intraocular lenses in which negative spherical aberration is induced, MINIFLEX optics is free from spherical aberrations, allowing for greater depth of focus and maintaining both visual acuity and contrast sensitivity intact in case of decentration.DESIGNED FOR MICS
“The incision size must be as small as possible.”1.8mm Injection System

surgery. The material’s high pseudoplasticity and the
visco-injection system allow for smaller incisions compared
to other IOLs, without compromising the implant’s
optical diameter or its stability. MINIFLEX can be implanted
through a 1.8mm incision using a docking injection
technique, or 2.2mm with the cartridge introduced in the
anterior chamber.
“The ideal design must ensure implant stability in the long run.”Self-Centering Double Haptics
MINIFLEX haptic design provides equalized compression force as the capsular bag contracts, with optimal fit to bags of all sizes.Step-Vaulted Haptic Angulation
• Keeps the haptics in parallel alignment with the optic at all times.Haptic Stress Absorbtion Cavity
• Prevents optical torsion and tilting.
• Concept validated in conformity to ISO-11979 optic torsion testing (<5º).
• Absorbs the mechanical stress generated by haptic compression.Large Capsular Contact Arc
• Isolates the optics from the haptic compression forces even
in the presence of capsular contraction, thus avoiding decentration.
• Concept validated through advanced finite element analysis
software.
MINIFLEX haptic design provides a wide area of contact between the haptics and the equatorial fornix of the capsular bag, improving IOL stability.
