The RayOne Trifocal is one of the most advanced intraocular lenses (IOLs) available today, it uses special technology to help you see clearly at different distances, reducing your need for glasses for most daily activities.

What are the benefits of RayOne Trifocal?

  • Rayner’s RayOne Trifocal is one of the most advanced intraocular lenses (IOLs) available today, giving you the opportunity to increase your independence from wearing glasses for all activity.
  • RayOne Trifocal uses diffractive step technology made up of 16 rings that split the incoming light to provide near, intermediate and distance vision.

 

What are the disadvantages of a Trifocal IOL?

  • You may experience reduced contrast compared to a monofocal IOL as well as some visual disturbances around lights at nighttime, however these typically reduce over time.
  • Not everyone is suitable for a trifocal lens and your surgeon will assess your suitability based on your eye health, personality and lifestyle. If you or your surgeon have any concerns about trifocality then you could consider the Sulcoflex Trifocal DUET procedure. 

As with all surgical procedures, the outcomes for a trifocal intraocular lens cannot be guaranteed. It is important to be aware of possible effects on vision after surgery. Please discuss possible risks and side effects with your eye surgeon. Not all patients are suitable for this type of intraocular lens. Your surgeon at the time of consultation will indicate whether this type of lens is suitable for you.

 

If you have some astigmatism in your eye, then your surgeon may be able to correct this at the same time with RayOne Trifocal Toric.

Side effects and complications to cataract surgery are rare. Some of the visual compromises that have been associated with the implantation of trifocal intraocular lenses are:

 

  • Lower contrast than that provided by a monofocal IOL
  • Halos and glare when driving at night
  • Visual disturbances including halos and glares, which decrease with time (neuroadaptation).

Improve your vision after cataract surgery with the Sulcoflex DUET procedure

The Sulcoflex DUET procedure involves implanting a special lens in your eye to improve vision after cataract surgery. This advanced technique enhances both distance and near vision, reducing the need for glasses.

  • Trifocal intraocular lenses (IOL) require a neuroadaptation period for the brain to adjust to the new way of processing light.

  • Neuroadaptation, which takes a few weeks, can be challenging for some individuals, so your surgeons may recommend the Sulcoflex Trifocal via the DUET procedure as a solution, which can be reversed if needed.

  • The DUET procedure involves an additional step during cataract surgery - after replacing the cataract with a standard IOL, a second IOL (Sulcoflex Trifocal) is added in front of the first. The two lenses collaborate to enhance vision and reduce the dependence on glasses.

  • The DUET procedure is safe and can be performed simultaneously with the initial cataract surgery, eliminating the need for a second operation.


  • What are the disadvantages of the Sulcoflex DUET procedure?


  • While the DUET procedure is designed to be reversible, additional surgery is required to remove the Sulcoflex Trifocal IOL if needed. This introduces the potential for additional risks and complications.

  • Trifocal IOLs, in general, can sometimes cause visual disturbances such as halos and glare, especially in low-light conditions. This can affect night vision and may take some time for adaptation.
