At some point in our lives, we may experience vision problems, such as cataracts or presbyopia, which can greatly affect our daily activities. One of the most common solutions to these problems is Clear Lens Exchange (CLE), which is also known as Refractive Lens Exchange or RLE. We will discuss everything you need to know about Clear Lens Exchange, including what it is, how it works, who is a good candidate for it, and what to expect before, during, and after the procedure.
What is Clear Lens Exchange?
Clear Lens Exchange is a surgical procedure that replaces the natural lens of the eye with an artificial intraocular lens (IOL). The procedure is very similar to cataract surgery, but instead of removing a cloudy lens, a clear lens is removed and replaced with an IOL to correct refractive errors, such as nearsightedness, farsightedness, astigmatism, and presbyopia. The goal of Clear Lens Exchange is to provide clear and sharp vision without the need for glasses or contact lenses.
How Does Clear Lens Exchange Work?
Clear Lens Exchange is typically performed as an outpatient procedure under local anesthesia, which means the patient will be awake but will not feel any pain. During the procedure, the surgeon will make a small incision in the cornea and use a phacoemulsification device to break up the natural lens into tiny pieces, which are then removed from the eye. Once the natural lens is removed, an artificial IOL is inserted into the eye through the same incision. The IOL is designed to correct the patient’s specific refractive error and provide clear vision.
Who is a Good Candidate for Clear Lens Exchange?
Clear Lens Exchange is a good option for people who are over 40 years old and have a moderate to severe refractive error, such as nearsightedness, farsightedness, astigmatism, or presbyopia. It is also a good option for people who have cataracts, but do not want to undergo cataract surgery twice. In addition, people who have thin corneas, dry eyes, or other eye conditions that make them unsuitable for LASIK or other types of laser vision correction may also be good candidates for Clear Lens Exchange.
What to Expect Before Clear Lens Exchange
Before Clear Lens Exchange, the patient will undergo a comprehensive eye exam to determine their eligibility for the procedure. This may include measurements of the cornea, pupil, and IOL power calculation to determine the appropriate IOL for the patient’s refractive error. The patient will also be asked to stop wearing contact lenses for a certain period of time before the procedure to ensure accurate measurements.
What to Expect During Clear Lens Exchange
During Clear Lens Exchange, the patient will be awake but will not feel any pain. The procedure typically takes less than 30 minutes per eye, and the patient can go home on the same day. The surgeon will use eye drops to dilate the pupil and numb the eye. The patient will be asked to look at a light during the procedure to keep the eye still. After the procedure, the patient may experience some mild discomfort and blurry vision, but this usually goes away within a few days.
What to Expect After Clear Lens Exchange
After Clear Lens Exchange, the patient will need to use eye drops to prevent infection and inflammation for several weeks. The patient should also avoid rubbing their eyes and engaging in activities that may put pressure on the eyes, such as heavy lifting or bending over. The patient should also avoid swimming and hot tubs for several weeks. The patient will need to attend follow-up appointments with the surgeon to monitor their healing and ensure that their vision is improving.
