One of the procedures done to correct the refractive error in the eyes is refractive lens exchange. It is also known as Lens Replacement Surgery.

The procedure corrects vision by replacing the clear natural lens of the eye with an artificial intraocular lens (IOL).

Cataract And Refractive Lens Exchange

Refractive lens exchange is similar to cataract surgery. However, RLE is not for cataract patients. During a cataract surgery, the focus is to remove the cloudy lens that causes blurred vision. On the other hand, refractive lens exchange aims at getting a patient off lenses and glasses. It makes focus sharp and clear.

Target Patients For The Procedure

Refractive Lens Exchange is recommended to people with extreme hyperopia and presbyopia, which cannot be corrected through Lasik or PhotorefractiveKeratectomy (PRK).

It is ideal for people above 40 years because as people age, the natural lens becomes more firm and hard, causing the eye not to focus on nearby objects quickly.

It would help if you visited a competent and experienced eye specialist who can ascertain your refractive lens exchange needs.

During the consultation, the specialist will do a thorough checkup to confirm the extent of the refraction. Your eye-doctor will also go through your medical history to find out whether there are no other conditions that would hinder the procedure.

The patient must be over 21 years

Types Of Intraocular Lenses Implants (IOL)

There are several refractive lens options:

1)      Mono-focal fixed-focus intraocular lens – clarifies focus for near, intermediate, and far distances. However, they don’t provide focus for multiple distances.

2)      Multifocal intraocular lens – They provide focus for multiple distances or ranges. This includes near, middle and far distances.

3)      Accommodating intraocular lens – This type of Mono-focal (IOL)enables a person to focus on multiple distances by the lens moving its position in the eye.

4)      Toric intraocular lens- This implant is ideal for people with astigmatism. A toric lens is designed for the uneven curve in the cornea or lens. 

Advantages of RLE

In addition to restoring a clear image, RLE has the following advantages:

  • Reduces the need to wear glasses. Often if one forgets to wear glasses they suffer from severe headaches and eye strain.
  • It is an appropriate option for Lasik- patients who are not the right candidates for Lasik surgery, can consider refractive lens exchange.
  • Refractive lenses are safe – refractive lenses are safe and reduce the risk of cataracts in the future.
  • Highly effective- Refractive lens exchange has a high success rate, with most patients walking free of glasses after the procedure.

Disadvantages of RLE

 The potential drawbacks for corrective eye surgery include:

  • Patients with corneal disease and other medical conditions cannot undergo RLE surgery.
  • Patients experience glare when around light.
  • Temporary redness of the eye. Some patients can also experience irritability in their eyes.
  • Some people may develop complications such as retina detachment and have infections. However, you can eliminate complications by visiting an experienced eye specialist.

Parting Shot

Refractive lens exchange is an effective intervention for anyone who wants to restore their sight and get off glasses. Although RLE has some limitations, an assessment visit to an ophthalmologist can help find a safe solution for your unique needs
