What is intracapsular lens extraction?
Intracapsular cataract extraction (ICCE) involves the removal of the lens and the surrounding lens capsule in one piece. The procedure has a relatively high rate of complications due to the large incision required and pressure placed on the vitreous body.
What is unifocal lens?
For patients with cataracts in both eyes, a Monofocal Intraocular Lenses may provide the most benefit. A monofocal IOL is an intraocular lens with a fixed focus for one distance.
How long does it take to get used to multifocal lens implants?
It may take them three days, three months or six months to adjust and learn how to adapt to their new vision. Some patients may not ever adapt and, for them, we should be ready to exchange a multifocal or EDOF lens for a monofocal IOL.
What is subluxation of lens?
In lens subluxation, zonular fibers are broken, and the lens is no longer held securely in place but remains in the pupillary aperture. Lens dislocation occurs following complete disruption of the zonular fibers and displacement of the lens from the pupil. Trauma is the leading cause of lens dislocation.
WHAT IS lens opacification?
Intraocularlens(IOL )Opacification is an uncommon but serious complication of cataract surgery. It can cause significant deterioration of visual performance and may necessitate IOL explantation1.
Is PanOptix a multifocal lens?
PanOptix, which is manufactured by Alcon Surgical, is the newest multifocal IOL implant to be introduced in the United States. This was approved by the FDA on August 27, 2019 and is currently available for usage.
Who should not get multifocal IOL?
If someone has an ocular comorbidity in either eye (eg, severe dry eye disease, irregular astigmatism, epiretinal membranes, macular degeneration), he or she is not eligible for a multifocal IOL. In my practice, this means that 50% of patients are ineligible. No. 2: Monofocal lens in the fellow eye.
What is the meaning of 6 6 vision?

IOLs come in different focusing powers, just like prescription eyeglasses or contact lenses. Your ophthalmologist will measure the length of your eye and the curve of your cornea. These measurements are used to set your IOLs focusing power.
What are multifocal IOLs?
Some IOLs have different focusing powers within the same lens. These are called multifocal and accommodative lenses. These IOLs reduce your dependence on glasses by giving you clear vision for more than one set distance. These IOLs provide both distance and near focus at the same time.
