Refractive Lens Exchange

As the year’s pass, the natural crystalline lens of our eye loses its ability to focus light from different distances.  This results in many individuals having to wear bifocals in order to see clearly.  The Refractive Lens Exchange is a surgical procedure that replaces the source of the problem, the aging lens, with an artificial advanced-technology intraocular lens.  In some ways, the procedure is similar to cataract surgery which has evolved greatly over the last twenty years to a 15 minute, suture-less, laser and ultrasonic procedure.  In cataract surgery, the natural crystalline lens is removed and replaced because it has become cloudy with age.  In Refractive Lens Exchange, the natural crystalline lens of the eye is not cloudy but is removed and replaced with an artificial advanced technology intraocular lens in order to reduce dependence on spectacles.  Unlike laser vision correction and LASIK which addresses the power of the cornea, this form of surgical vision correction addresses the source of the blurry vision, the aging crystalline lens.
