There is an exciting option for individuals over 45 who are considering vision correction and have been told that they’re not a candidate for LASIK. It’s called Clear Lens Exchange – or CLE for short.
CLE also known as Clear Lens Extraction, Refractive Lensectomy, Presbyopic Lens Exchange (PreLex), or Refractive Lens Exchange, is essentially the same procedure as cataract surgery. However, CLE is preformed prior to the development of cataracts for the refractive benefits.
CLE is well suited for people over 45 because that is the age that most people begin to lose their ability to focus up close. This occurs when the natural lens becomes less flexible, and no longer accommodates as well to changing its focus from distant to near objects. It is then that reading glasses or bifocals are prescribed.
Unlike LASIK or PRK that correct vision by reshaping the cornea, CLE corrects your vision by changing the focusing power of the eye’s lens. To do this, Dr. Bryan will replace your natural lens with an artificial intraocular lens implant (IOL) to achieve clearer eyesight. Some doctors use a lens that has a fixed focal length that does not accommodate for near vision. In our experience, most patients want a full range of vision. That is why Dr. Bryan prefers the FDA-approved AcrySof® ReSTOR® IQ implant which allows you to enjoy clear distance and near vision without the need for reading glasses or bifocals.
If you would like to enjoy the benefits of clear lens exchange but have astigmatism, Dr. Bryan may recommend a different advanced lens called the AcrySof® Toric lens. It’s the first IOL that treats farsightedness or nearsightedness along with any preexisting astigmatism.
Both implants are permanent. Since your lens has been replaced with an artificial one that never clouds, patients who have CLE preformed will never develop cataracts nor will they ever require cataract surgery in the future.
Dr. Bryan performs this virtually painless surgery with no injections at all, only anesthetic eye drops. He will make a tiny incision in your eye, remove its natural lens, and replace it with a new lens. The actual surgery can take minutes and the results are permanent and life changing. You will return home to rest after surgery. Steroid, antibiotic and anti-inflammatory eye drops are given to you for comfort and to promote healing. Most of our patients are back to their normal activities the following day.
One eye is scheduled at a time, usually one week apart. It may take you some time to get accustomed to your new vision. Many patients see better within a week or two and may continue improving for several weeks.
