PreLEX Treatment To Remove Bi-Focals

PreLEX treatment (Presbyopic Refractive Lens Exchange) is a lens replacement procedure wherein the natural lens is replaced with a multi-focal intra-ocular lens implant. This is done to improve vision for those generally above the age of 40, as it is after this age that one’s eye sight begins to naturally become weak—causing blurred near vision while reading or working at the computer, with/without blurred far vision when looking at something from a distance. Such blurring of the eye sight in those aged 40 and above is referred to as presbyopia.

Though LASIK surgery improves distance vision; after the age of 40, near vision becomes blurred because the natural lens becomes less flexible, and therefore, LASIK would not offer much benefit. PreLEX removes the natural lens and implants a multifocal lens, improving eye sight of the patient for distance and near, giving complete spectacle independence. . And it takes only 15 minutes!

What are the eye conditions treatable with PreLEX?

When you’re suffering from a particular eye condition, the first recommended step is to meet your ophthalmologist. He/she will check the severity of your eye condition and suggest the treatment most suited for you.

Besides presbyopia, PreLEX is helpful in treating various other eye conditions.

  • Cataracts
  • Myopia (near sightedness)
  • Hyperopia (far sightedness)

Though LASIK can also be performed to cure the above conditions, your ophthalmologist will be your best guide to decide which treatment will reverse your vision loss. PreLEX can be performed even if you’ve had other eye surgeries in the past.

How is the PreLEX procedure performed?

Before the surgical procedure is undertaken, a comprehensive eye examination is taken to learn more about your eye and confirm if PreLEX is the right procedure for you. After this, the following steps are carried out:

  • Topical/Local anaesthesia is given.
  • Ultrasound energy is used to make a small incision, and remove the natural lens of the eye through a small incision.
  • A multi focal intra ocular lens is implanted in its place
  • PreLEX is performed on both eyes on separate visits. Surgery in the second eye can usually be performed as soon as one to two weeks later.

In most cases, vision improvement is experienced immediately after the procedure and this improvement continues to become better in the next 3 to 6 months. Post-operative care includes avoiding activities that involve heavy weight-lifting and regular follow-up visits are essential as advised.

What are the risks of PreLEX surgery?

All surgical procedures have inherent risks of varying degrees. Risks associated with PreLEX surgery are similar to those after routine cataract surgery and include:

  • Infection
  • Bleeding
  • Scarring
  • Adverse reaction to anaesthesia

But, if the surgery is performed under the care of an experienced ophthalmic surgeon, the benefits far outweigh the risks involved.

What are the benefits of PreLEX surgery?

The foremost benefit is of having improved vision for distance and near that does not need to depend on glasses or contact lenses, for both near and far vision. According to the U.S. Food and Drug Administration, 80% of the patients who undergo PreLEX treatment, do not require glasses or contact lenses for better vision.
