About Refractive Lens Exchange
What is Refractive Lens Exchange (RLE)?
Refractive lens exchange, also known as lens replacement surgery or clear lens extraction, may be a better option than LASIK, PRK or IOL, to correct presbyopia or farsightedness. Refractive lens exchange removes the crystalline lens of the eye and is replaced with an artificial lens implant to correct refractive error achieving sharper focus and reducing the need for reading glasses or bifocals. Refractive lens exchange is almost identical to cataract surgery, however the lens being replaced is clear instead of a cloudy lens caused by a cataract.
Are You a Candidate for RLE?
- Experiencing presbyopia and want to decrease dependency on reading glasses
- Free of eye disease
- Thin corneas
- Poor candidate for LASIK
- Typically an older patient
- Require corrections for severe myopia, hyperopia, or astigmatism
About Intraocular Lenses (IOL)
An IOL, or intraocular lens, is a lens implanted in the eye used to treat cataracts or myopia. An IOL is used in surgeries that involve removing the natural lens of the eye and replacing it with an IOL inside the eye. Corrective glasses may be needed after surgery for reading and close work, although they are not as thick and heavy as traditional cataract glasses. IOLs are commonly chosen to provide better distance vision than near vision, and glasses are used for sharp near vision. Sometimes IOLs are chosen to provide better near vision for reading and use glasses for distance vision. However, there are a variety of premium IOL types available that are designed to provide both distance and near vision focus at all times. Most premium IOLs are designed to eliminate your need for, or reduce your dependence on glasses as compared to standard IOL. A premium IOL is an upgrade from a standard IOL. Your ophthalmologist will discuss your vision goals with you and perform a series of simple tests to determine which IOL option is best for you.
Shaped to provide good vision in just one particular range of distances, either near or distance vision. If you have this type of IOL implanted, you will probably need glasses to provide clear vision in the other range. The most common monofocal option to be chosen is to provide better distance vision than near vision. Then glasses are worn for sharp near vision.
MULTIFOCAL PREMIUM IOL
Designed to provide correction for both near and distance vision. Therefore, both near and far objects can be in focus at the same time. The brain must learn to select the visual information it needs to form an image of near or distant objects. It will take some time to adjust to a multifocal IOL, and the adjustments may be easier if placed in both eyes
ACCOMMODATING PREMIUM IOL
Works naturally with the eye muscles and is designed to allow the lens to move, or accommodate, and focus on objects near, far, and all distances in-between.
TORIC PREMIUM IOL
Offers patients with moderate astigmatism better vision without glasses. Astigmatism is a common eye condition caused by an irregularly shaped cornea or lens, and causes distorted or blurred vision. Glasses may be needed to correct the astigmatism if other IOL options are used.
ASPHERIC PREMIUM IOL
Slightly flatter in the periphery as opposed to the traditional IOLs that are spherical, meaning the front surface is uniformly curved. An Aspheric IOL is designed to provide better contrast sensitivity which may improve the ability to see in varying light conditions such as rain, snow, fog, twilight and nighttime darkness.
