Complaints about a contact lens solution linked to a 2007 outbreak of eye infections that blinded several people went unreported by the manufacturer for more than a year. Advanced Medical Optics received complaints about the solution more than a year before it was recalled, and failed to promptly report nine complaints as required by law.
A phakic IOL. An intraocular lens (IOL) is a lens implanted in the eye usually as part of a treatment for cataracts or for correcting other vision problems such as short sightedness and long sightedness; a form of refractive surgery. If the natural lens is left in the eye, the IOL is known as phakic, otherwise it is a pseudophakic lens (or ...
People who have a multifocal intraocular lens after their cataract is removed may be less likely to need additional glasses compared with people who have standard monofocal lenses. [2] People receiving multifocal lenses may experience more visual problems, such as glare or haloes (rings around lights), than with monofocal lenses. [2] People ...
Cataract surgery, also called lens replacement surgery, is the removal of the natural lens of the eye that has developed a cataract, an opaque or cloudy area. [1] The eye's natural lens is usually replaced with an artificial intraocular lens (IOL) implant.
Clear lens extraction, also known as refractive lensectomy, custom lens replacement or refractive lens exchange is a surgical procedure in which clear lens of the human eye is removed. Unlike cataract surgery , where the cloudy lens is removed to treat a cataract , clear lens extraction is done to surgically correct refractive errors such as ...
In 2009, Praputsorn Kosakarn described a method for manual fragmentation of the lens, called "double-nylon loop", which consists in splitting the lens into three pieces for extraction, allowing a smaller, sutureless incision of 4.0 to 5.0 mm (0.16 to 0.20 in), and requires implantation of a foldable IOL. This technique uses less expensive ...
Multifocal intraocular lenses are designed to avoid the need for glasses by providing two or more points of focus. Multifocal glued IOL procedures have been done with the ReZoom (Abbott Medical Optics), and Tecnis (Advanced Medical Optics (AMO)) IOLs. This makes it possible to offer the accommodative IOL advantage even to patients with an ...
When the posterior capsule is damaged, the IOL may be inserted into the ciliary sulcus, [18] or a glued intraocular lens technique may be applied. [19] It is economical to use a rigid IOL if the incision size is already over 6 mm wide, but foldable IOLs can also be used if cost is not a limiting factor or incision size is <5 mm. [4]
