Phakic Intraocular Lens (PIOL) Implantation 

Phakic intraocular lenses (PIOLs) are lenses implanted in the eyes to correct vision problems without removing the natural eye lens. PIOLs are made with clear advance synthetic material look like plastic. The surgeon can insert the lens in front or behind the pupil. The placement is similar to inserting a contact lens in the eye.  

Implanting PIOL effectively treats high prescriptions and is usually suitable for treating younger patients who cannot undergo laser eye surgery or even as first choices to treat prescription . 

The most popular PIOL is the Staar ICL or  ” Intraocular Collamer Lens”. This lens is soft and designed to be fitted behind the pupil (colour part of your eyes), in front of the natural eye lens. You can’t feel or see the lens after its implantation, and it doesn’t need cleaning. 

The second type of PIOL is the Verysise/Artisan PIOL. This lens fits on the iris, in front of the pupil. In some cases, it is visible as a glint in the eye. Like the ICL, you can’t feel the Varysise/Artisan PIOL after its implantation, and it doesn’t require cleaning. 

If you are a good candidate for PIOL, the surgeon will discuss with you to determine the right option for you. 

What are the benefits of PIOLs?

PIOLs are an effective treatment for people with astigmatism and moderate to high prescription whether shortsighted or longsighted. Many patients who undergo PIOL surgery have a vision similar to when wearing contact lenses, but they do not experience the limitations and discomfort from removable contact lenses or glasses. 

This treatment is mainly reversible, as PIOL can be removed or replaced, this is a big advantage compare to other refractive treatments for correction of prescriptions including laser eye surgery.

These surgeries performed very routinely and carry low risks, your surgeon will discuss the details and risks and benefit for you.

Who can undergo PIOL?

Any candidate who pass the screening can be suitable for PIOL however majority of people who cannot undergo laser vision correction may be suitable for PIOL implantation as well because PIOLs can correct higher prescriptions than laser vision treatments. PIOL surgery may also be a safer treatment option if you have eye surface issues or pre-existing cornea problems.  

PIOL can effectively treat the following prescription.

  • Up to +10.00 of long sight or hyperopia
  • Up to -20.00D of short sight or myopia
  • Up to ± 6:00D of astigmatism 

Supplementary vision correction can even extend the range for right candidates with extremely high prescriptions as a combination treatments.
