What kind of doctor provides Refractive Lens Exchange?
An ophthalmologist, an eye doctor trained to perform eye surgery, performs refractive lens exchange, also called RLE. RLE replaces the natural lens of the eye with an artificial lens to improve vision. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What it is
RLE is one of several surgeries that improve vision. They range from reshaping the cornea with lasers to placing artificial lenses in the eye. RLE is also called clear lens extraction. With RLE, an artificial lens replaces your eye's natural lens to improve vision. The procedure is done much like cataract surgery. The new lens is called an IOL, short for intraocular lens.
RLE may use multifocal or accommodative lenses. They let you focus at all distances. RLE is not FDA-approved. Ophthalmologists may still choose to perform it. This is called an off-label use.
Why a doctor might recommend it
Some people who have early stage cataracts may choose RLE instead of waiting for their cataracts to progress. The lens implants generally give them better vision without glasses or contacts. This is most true if they already need vision correction.
RLE may also be an option for people with severe farsightedness, for whom LASIK is not recommended.
How to prepare
A full exam of the front and back of the eye is needed to see if you can have RLE.
What happens during it
RLE is performed much like cataract surgery. In RLE, an artificial lens replaces the eye's natural lens.
Recovery
A detached retina is a medical emergency. If you have symptoms of a detached retina, go to your eye doctor or the emergency room right away. Retinal detachment can cause permanent vision loss, but getting treatment right away can help protect your vision.
Symptoms of a detached retina include the following.
- A lot of new floaters, which are small dark spots or squiggly lines that float across your vision
- Flashes of light in one eye or both eyes
- A dark shadow or curtain on the sides or in the middle of your vision
Risks and side effects
The retina is a light-sensitive layer of tissue in the back of the eye. In a detached retina, the retina is pulled away from its normal position. People who have had eye surgery, like surgery to treat cataracts, are at higher risk of a detached retina. RLE is done much like cataract surgery. People with extreme nearsightedness are also at higher risk. Treatment for a detached retina includes laser treatment or surgery.
Who performs it
Ophthalmologists legally may choose to perform RLE.
Common questions
Is refractive lens exchange the same as cataract surgery?
RLE is done much like cataract surgery. Some people who have early stage cataracts choose RLE instead of waiting for their cataracts to progress.
How is RLE different from LASIK?
RLE replaces the eye's natural lens with an artificial lens, while LASIK uses a laser to reshape the cornea.
Who might choose RLE?
Some people with early stage cataracts may choose RLE instead of waiting. It may also be an option for people with severe farsightedness for whom LASIK is not recommended.
How is RLE different from a phakic IOL?
RLE replaces the eye's natural lens, while a phakic IOL leaves the natural lens in place. With a phakic IOL, people keep their ability to focus. A phakic IOL is placed inside the eye, in front of the natural lens.
How does a direct primary care or concierge doctor fit in?
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance.
