Refractive Lens Surgery

Refractive Lens Exchange (RLE) is a procedure to reduce or eliminate dependence on glasses. It is an alternative to Laser vision correction and may be the procedure of choice for those over the age of 40 who desire freedom from glasses at all distances. It corrects nearsightedness, farsightedness, astigmatism and even presbyopia. Presbyopia is a progressive condition typically requiring individuals over the age of 40 to become dependent on reading glasses or bifocals segments in their glasses to see things at near, like reading, sewing and computer activities.

While laser vision correction like LASIK corrects vision by reshaping the cornea, RLE corrects vision by replacing the eye's natural lens with an intraocular lens (IOL) of the appropriate power customized to each individual eye. Each IOL is customized using the patient's unique ocular measurements and the IOL calculated for each eye is implanted into the eye during a 7-8 minute surgery. It can correct all refractive errors, allowing a lifetime of freedom from glasses! 

The Symfony Lens

The Symfony lens is an extended depth of focus lens implant which treats presbyopia (loss of near vision from age).  It is implanted into the eye during a normal cataract surgery after the removal of the cataract or during a refractive lens exchange surgery. It corrects distance vision, near vision and provides continuous high quality vision at all distances and in all lighting situations.  In most cases recovery time is minimal, with patients able to return to their usual routine just 24 hours after surgery. Unlike traditional multifocal lens implants, there is minimal glare or halos with the Symfony lens and no reduction in contrast sensitivity. This is achieved through  a special diffractive grating in the lens implant allowing it to manipulate chromatic aberration. This allows it to function similar to a traditional monofocal lens implant for distance but with the added benefit of intermediate and near vision.  

The Raindrop® Near Vision Inlay

The Raindrop® Near Vision Inlay is a transparent hydrogel cornea inlay that is designed to correct presbyopia (loss of near vision from age).  It is placed beneath a corneal flap that is created bladelessly with a femtosecond laser. The procedure takes about 5-10 minutes and is performed at Paducah Lasik Center located in our office.  It is made of a proprietary hydrogel material comprised of nearly 80% water. The optical characteristics are almost identical to the human cornea.  It is placed in one eye, the non-dominant eye, and restores the ability to read and perform near activities without reading glasses to those patients who have lost this as a result of aging.   The ideal patient for the Raindrop® Near Vision Inlay is between the age of 41 and 65 with good uncorrected distance vision, has a normal and healthy ocular surface and does not have cataracts, glaucoma, uncontrolled diabetes or a history of herpetic eye disease.
