According to the NHS, cataract surgeons perform cataract surgery over 300,000 per year in only Uk. This is a common question asked by many patients who choose cataract surgery.

Should I use a Multifocal Intraocular lens for my Cataract Surgery?

The option of implantation of multifocal IOL for cataract surgery is not yet available on the NHS. In routine cataract surgery, we implant usually a mono-focal intraocular lens. It means that this type of lens implant is fixed to focus on one distance. Generally, most of the patients prefer to be fixed for the distance. It helps to focus on the environment around them. This is what we concentrate on mostly.
Patients with mono-focal IOL implants for fixed distance are required to use additional reading glasses to focus on near objects such as books, newspapers, and smartphones. The high success rate of cataract surgery is based on this type of intraocular lens. At present, it is the most commonly used best and validated lens for cataract surgery.
Multifocal IOL was designed to get better vision results than the mono-focal intraocular lens. The multifocal intraocular lens allows patients to see at multiple distances that means the multifocal lens users can see at near and distance. This enables the patients to see the world in focus around them and also enables them to see writing in a newspaper and on the smartphone. There is a question that arises:

What are the Side Effects of Multifocal Intraocular lens Implants?

  • The first reason is that the cost of multifocal intraocular lenses is more than mono-focal intraocular lenses.
  • A multifocal lens is designed to focus on multiple distances or points. Because of the multiple focuses points, each point is not quite as clear.
  • A person with multifocal IOL may have slightly reduced sharpness to their distance vision.
  • It slightly reduced the sharpness in reading close the vision.
  • A small number of patients may accept having seeing problems with glare or haloes in dim light such as at night.
  • Patients while driving at night can explain glare or haloes around headlamps. This cause creates the feeling of not being safe to drive at night. Therefore multifocal IOL is not suitable for those who are in activities to drive at night time. 
  • Multifocal IOL is not best for those patients who have other eye diseases such as age-related macular degeneration or diabetic maculopathy.
  • Multifocal IOL is not recommended for those patients who have already macular conditions affecting their vision.
  • There are some patients who still need reading glasses.
  • Multifocal IOLs usually works best if it is implanted in both eyes.
  • Patients should aware of this responsibility there is no chance to undergo further surgery to remove the lens or replace it with another better one.

Why are my Multifocal Contacts blurry?
