Clinical studies have not been conducted with the Akreos™ Advanced Optics Aspheric
Lens to
assess the effect of the added aspheric surface to the parent lens Model Akreos
on spherical aberration, visual acuity and contrast sensitivity.
INDICATIONS: Akreos posterior chamber lenses are indicated for primary implantation for
the visual correction of aphakia in adult patients where a cataractous lens has
been removed by phacoemulsification. The lens is intended for placement in the capsular
bag. CONTRAINDICATIONS: Implantation is not advisable when the IOL may aggravate
an existing condition, interfere with the diagnosis or the treatment of a pathology,
or present a risk to the sight of the patient. These conditions are uncontrolled
glaucoma, rubeotic cataract, retinal detachment, atrophy of the iris, microphthalmia,
developing chronic eye infections, endothelial corneal dystrophy, perioperative
complications (such as vitreous loss, hemorrhage...), foreseeable postoperative
complications. WARNINGS: Physicians considering lens implantation under any of the
following circumstances should weigh the potential risk/benefit ratio: a. Recurrent
severe anterior or posterior segment inflammation or uveitis. b. Patients in whom
the intraocular lens may affect the ability to observe, diagnose, or treat posterior
segment diseases. c. Surgical difficulties at the time of cataract extraction that
might increase the potential for complications (e.g., persistent bleeding, significant
iris damage, uncontrolled positive pressure, or significant vitreous prolapse or
loss). d. A distorted eye due to previous trauma or developmental defect in which
appropriate support of the IOL is not possible. e. Circumstances that would result
in damage to the endothelium during implantation. f. Suspected microbial infection.
g. Children under the age of 2 years are not suitable candidates for intraocular
lenses. h. Patients in whom neither the posterior capsule nor zonules are intact
enough to provide support. •Since the clinical study for the Akreos intraocular
lens was conducted with the lens being implanted in the capsular bag only, there
are insufficient clinical data to demonstrate its safety and efficacy for placement
in the ciliary sulcus. •Improper handling or folding techniques may cause damage
to the haptic or optic portions of Akreos foldable lenses. If lenses are not folded
according to directions, optic tears may result (see “Directions for Use”). Physicians
should not attempt to implant lenses that have radial optic tears or separations.
•Use of folding instruments other than those validated and recommended in the labeling
might result in IOL damage (optic tears, haptic damage) that might require IOL explantation.
•To avoid the creation of permanent forcep marks in the central optic zone, exercise
care during handling and insertion of the lens. Read and follow the folding and
insertion instructions carefully. PRECAUTIONS: 1. Do not attempt to resterilize
these lenses.
2. Do not store the IOL package in direct sunlight or at temperatures
below freezing (<0°C).
Store at room temperature. Avoid high temperatures
(>45°C). 3. Do not implant the IOL if the outer pouch or vial is
opened or damaged. 4. Do not reuse the IOL. 5. Do not soak or rinse lenses in solutions
other than balanced salt solution or equivalent. 6. A high level of surgical skill
is required for intraocular lens implantation. A surgeon should have observed and/or
assisted in numerous surgical implantations and should have completed one or more
courses on intraocular lens implantation before attempting to implant intraocular
lenses. 7. The IOL should be used in the shortest possible time after opening the
vial. 8. Do not implant the IOL if the lens is not completely immersed in solution
under any vial orientation. 9. Akreos IOLs can absorb substances that\they contact
(disinfectant, drug…). Do not place the lens in contact with surfaces where such
contamination can occur. 10. If a YAG laser posterior capsulotomy is performed,
assure that the laser beam is focused slightly behind the posterior capsule. 11.
As with any surgical procedure, there is risk involved. Potential adverse events
and complications accompanying cataract or implant surgery may include, but are
not limited to the following: corneal endothelial damage, infection (endophthalmitis),
retinal detachment, vitritis, cystoid macular edema, corneal edema, pupillary block,
cyclitic membrane, iris prolapse, hypopyon, transient or persistent glaucoma and
secondary surgical intervention. Secondary surgical interventions include, but are
not limited to, lens repositioning, lens replacement, vitreous aspirations or iridectomy
for pupillary block, wound leak repair, and retinal detachment repair. Amongst those
directly related to the IOL are decentering and subluxation, precipitates on the
surface of the IOL. Silicone oil, particularly when used in the surgical treatment
of detached retina, may stick to the IOL if the posterior capsule of the crystalline
lens is not intact. *Clinical studies have not been conducted with the Akreos Advanced
