Premium lenses for cataract surgery

Cataract surgery is one of the most common and effective procedures for restoring vision, especially in older adults. Traditionally, the standard lens implant, or intraocular lens (IOL), used in cataract surgery restores vision at a single distance, usually for distance vision. However, premium lenses offer advanced solutions, enabling clearer vision at multiple distances and reducing dependence on glasses.

What are premium lenses?

Premium lenses, or premium intraocular lenses (IOLs), are designed to address vision issues beyond what standard monofocal lenses can offer. These lenses may correct for near, intermediate, and far vision, as well as for astigmatism.

Types of premium lenses for cataract surgery

1. Toric monofocal lenses:
   • These lenses are designed to offer clear vision for a single focus (either distance, or near - but not both) by reducing the residual astigmatism a patient has following cataract surgery. 
   • It is important to note that not all NHS units provide toric monofocal lenses. NHS units that do provide toric monofocal lenses may require a patients' level of astigmatism to be over a certain threshold before being able to offer a toric monofocal lens to them. 

2. Extended depth-of-focus (EDOF) lenses (+/- toric):
   • EDOF lenses improve vision across a continuous range, mainly enhancing intermediate and distance vision with less glare and fewer visual disturbances than some other multifocal lenses.
   • Ideal for those who engage in activities like driving or playing sports, these lenses may still require glasses for very close-up tasks like reading fine print.
   • These lenses can be ordered in a toric and non-toric version depending on the level of astigmatism a patient has at their pre-operative assessment.
   • These lenses can be accessed in the private sector.

3. Trifocal lenses (+/- toric):
   • Trifocal lenses are designed to improve vision equally across distance, intermediate and near.
   • There may be a higher risk of glare and other visual disturbances post-operatively compared to EDOF lenses
   • These lenses can be ordered in a toric and non-toric version depending on the level of astigmatism a patient has at their pre-operative assessment.
   • These lenses can be accessed in the private sector.

What are the benefits of premium lenses?

• Reduced dependence on glasses: Many people find they need glasses less frequently, particularly for reading or computer work.
• Correction of pre-existing visual issues: For those with conditions like astigmatism, premium lenses can help correct these issues during cataract surgery.

What are the potential drawbacks?

• Higher cost: Premium lenses are typically more expensive and often not covered by the NHS.
• Possible side effects: Some people may experience glare, halos, or a slight decrease in contrast sensitivity, especially with multifocal lenses.
• Adaptation period: The brain may need time to adjust to the new visual input, particularly with multifocal lenses.

Who is a candidate for premium lenses?

Premium lenses are suitable for individuals who are highly motivated to reduce their dependence on glasses. People who have specific vision needs, such as frequent close-up work or sports that require good depth perception, may find these lenses particularly beneficial. However, not everyone is a candidate, and suitability depends on factors like eye health, lifestyle and budget.

Questions to ask your eye surgeon

1. Which type of premium lens is most suited to my lifestyle?
2. What are the long-term benefits and risks associated with the lens?
3. What side effects might I expect, and how are they managed?
4. Is there a need for further correction or enhancement after surgery?

Premium lenses in cataract surgery represent a significant advancement, allowing patients to enjoy clearer vision at multiple distances and a more flexible lifestyle. Consulting a specialist is essential to weigh the options and determine the best choice for your unique vision needs.
