What is intraocular lens exchange?
Refractive lens exchange (RLE) replaces your eye’s clear natural lens with an artificial intraocular lens (IOL) to correct your refractive error and achieve sharper focus, reducing your need for reading glasses or bifocals.
What is intraocular lens used for?
Medical uses. Intraocular lenses have been used since 1999 for correcting larger errors in near-sighted, far-sighted, and astigmatic eyes. This type of IOL is also called phakic intraocular lens (PIOL), as it is implanted without removing the patient’s natural crystalline lens.
What is a standard intraocular lens?
A standard IOL is a monofocal lens that, after cataract extraction, replaces your natural lens, correcting your vision at one focal distance. If you are seeking to reduce your dependence from glasses or contact lenses, monofocal IOL implants may not be the best option for you.
What is intraocular lens material?
Current materials used for IOL optics are of two types—acrylic and silicone. Acrylic materials can be rigid (PMMA) and foldable made of hydrophobic acrylic materials (AcrySof – Alcon Laboratories, Sensar – Advanced Medical Optics –AMO) and hydrophilic acrylics (Centerflex, Akreos).
Which IOL is best?
There is no single IOL that is “best” for every person. It all comes down to finding the best set of lenses to address your specific needs. They might even recommend mixing two different multifocal lenses or two different types of intraocular lenses.
What is the cost of IOL in India?
The state FDA has surveyed 15 brands of intraocular lenses used in India, and found that cost for the retailer or the hospital starts from Rs 350 and goes up till Rs 15,200 for a lens. The cost to the patient, however, ranges between Rs 5,800 to Rs 26,550.

What does intraocular lens mean?
Intraocular lens ( IOL ) is a lens implanted in the eye as part of a treatment for cataracts or myopia. The most common type of IOL is the pseudophakic IOL. These are implanted during cataract surgery, after the cloudy eye’s natural lens (colloquially called a cataract) has been removed.
What are intra ocular lenses, or lens implants?
An intraocular lens implant is an artificial replacement for the lens of your eye. It’s part of the surgery to fix cataracts. Each eye has a lens — a window made of clear protein and water that sits behind the pupil. The lens focuses light onto the retina, which sends it to your brain.
Why are trifocal intraocular lenses?
IOLs are often used to replace natural eye lenses in people who have cataracts. Trifocal IOLs are a recent development in vision correction . They’re made of a synthetic material, such as silicone or plastic, and have different zones on the lens to correct different types of vision. They also protect your eyes against ultraviolet rays.
What are ICL phakic intraocular lenses?
Phakic intraocular lenses (IOLs), also known as implantable contact lenses (ICLs), are implantable contact lenses that are surgically inserted into the eye where they provide excellent quality of vision with predictable and stable results.
