RLE (Lens exchange) also called Clear Lens Extraction (CLE), is a non-laser eye surgery where the natural lens of the eye is removed and replaced with a silicone or plastic intraocular lens (IOL). It is suitable for patients over the age of 40 years with disorders beyond the scope of laser eye surgery.
The main advantage of RLE (Lens Exchange) is that it is possible to remove any number of diopters through this method. It is also a preventive treatment; patients after refractive lens exchange are no more at risk of cataract and the risk of paroxysmal glaucoma is reduced.
Therefore, it is an excellent choice for patients in which a high number of diopters is combined with familial predisposition to cataract and glaucoma.
To patients who would also like to get rid of reading glasses, the PRELEX method is recommended, which is refractive lens exchange completed with so-called multifocal intraocular lens implantation.
RLE (Lens exchange) is performed on an outpatient basis and usually only takes about 15 minutes. Once the eye has been anesthetized and cleaned, the doctor will create a small incision on the eye under an operating microscope.
The natural lens is gently fragmented and removed by the use of ultrasound. Then an plastic intraocular lens (IOL) is implanted to replace the natural lens. There are three types of IOL’s, and the doctor will decide which is the best IOL. The incision is then closed and a protective shield is placed on your eye.
