Refractive Lens Exchange

RLE (Refractive Lens Exchange)

RLE is also known as refractive lens surgery, lens replacement surgery or clear lens exchange (CLE).  Using an intraocular lens (IOL), to replace the natural lens within the eye is a revolutionary way to correct myopia (short sight), hyperopia (long sight), astigmatism (imperfection in the curvature of the eye) and presbyopia (age related loss of near vision).  This procedure type is suitable in patients in their mid 40’s and older.

RLE surgery is completed using the same technique as cataract surgery although no cataract is present.  The clear natural lens inside the eye is removed and replaced with an artificial intraocular lens (IOL).  It is popular with patients who are above the age of 45.  RLE is a great alternative to laser eye surgery for those over 45 as it can offer a more permanent near vision result as well as great distance vision.  By replacing the natural lens, you will never suffer with cataracts or the visual deterioration caused by cataracts.

At your consultation

Dr Furness will establish the degree of refractive error present (glasses prescription) and determines which lens option will work best based on the tests performed and your visual preferences.

There are various intraocular lenses available to suit all people and they provide different visual results.  For example:

Monovision both distance and near vision can be achieved (without glasses) using a standard single focus lens.   Your dominant eye is corrected to give you clear distance vision and the non-dominant eye is corrected for near/reading vision.  The brain creates a merge between the images from each eye giving you optimal intermediate vision also.  Approximately 20% of patients brains cannot adapt to the difference in vision between the two eyes and are therefore; not suitable for a monovision correction.

Trifocals (also known as multifocals)  Distance, intermediate and near vision can be achieved without glasses or contact lenses using this type of lens.  Trifocal’s are an alternative for those that do not tolerate monovision or just prefer the idea of this over monovision.  Using newest available lens technology, FineVision, created by Bausch & Lomb, many patients don’t need to wear glasses for everyday tasks such as driving, reading the car speedometer or even using their smart phone.

Distance vision only Single vision lenses are used to correct the distance vision to achieve clear unaided distance vision.  In most cases, the patient will require near vision glasses for reading and other near vision tasks.

What happens on the day of surgery?

RLE surgery takes only 30 minutes and your outpatient visit to Perth Eye Hospital will be approximately 3 hours.  You are required to begin an eye drop 3 days prior to your procedure and more medicated eye drops will be provided by the nursing staff on the day of your procedure.  You will be advised to take these eye drops for a short period after your procedure to optimize your healing time and reduce the likelihood of post operative complications.
