Implantable Contact Lenses

What's an implantable contact lens?

An Implantable contact lens (ICL for short) is placed inside your eye in order to permanently correct your vision. An ICL can be placed either in front of, or behind, your iris (the colored part of your eye).

 

Other names for ICLs include implantable collamer lens and phakic intraocular lens.

 

ICLs provide an alternative to reading glasses or contact lenses for those patients who are not good candidates for LASIK due to severe myopia or astigmatism.

Are there Implantable contact lens options?

 

At AEI, we offer two brands of FDA approved implantable contact lenses: VisianTM and VerisyseTM. Each one has unique characteristics that can make it the best option for certain circumstances. Both offer built-in ultraviolet filters that protect your eyes from UV rays.

 

Both brands also offer special ICLs designed for people with astigmatism, which are called Toric ICLs. You'll get this type of lens if you have a cornea that's more football-shaped than round. A toric ICL lessens the blurry vision caused by astigmatism so you won't need glasses to correct it after your ICL is inserted.

  

Visian brand implantable collamer lenses

Visian lens have been placed in over a million eyes worldwide since their FDA approval in 2005. These lenses are made of a thin pliable material called collamer that's a combination of collagen and polymer. Because collagen is made by the human body, our body doesn't recognize collamer as foreign. This lowers the Visian lens' rejection risk to nearly zero.

 

The Visian lens is inserted behind your iris (the colored part of your eye) and in front of the natural lens.

 

Visian provides excellent quality of vision. In fact, over 94 percent of patients in clinical trials reported excellent or good vision quality after receiving their ICL. What's more, over 98 percent said that they'd undergo Visian ICL implantation again if given the choice.

 

Verisyse ICLs

Verisyse are different from Visian in two important ways:

  • Verisyse are made of a rigid plastic material called polymethylmethacrylate (PMMA).
  • The Verisyse lens is placed in front of your iris (the colored part of your eye). This allows them to be easily swapped out if your vision changes over time.

 

Which ICL lens is best for me?

The appropriate lens choice will be determined by you and your eye doctor following a detailed eye exam using specialized equipment to measure your vision deficits, the shape of your eye and also identify any irregularities on the surface of your eye.

 

This is done to ensure the most precise vision correction and lens fit possible.

 

Am I a good candidate for implantable contact lens?

You are a good candidate for an implantable lens if:

  • You are between 21 and 45 years old
  • You don't qualify for Lasik or PRK due to a high degree of nearsightedness (myopia) or having thin corneas or dry eye syndrome
  • Your refractive error measures between -3.0 to -20.0 diopters
  • You have not had any prior eye surgery
  • You do not have certain eye conditions such as iritis, uveitis, glaucoma or diseases associated with poor tissue healing such as diabetic retinopathy, connective tissue disease or autoimmune diseases
  • You are not nursing or pregnant
  • Your vision prescription has remained stable for at least one year
  • Your eye exam confirms that you meet certain physical requirements needed for ICL implantation

 

Implantable contact lens surgery risks

Although no surgery is without risk, ICLs have been available for two decades in Europe and placed in nearly one million eyes, so they've been widely studied. However small the likelihood of a complication may be, you should be aware of it when considering ICL surgery.

 

Complications from ICL surgery can include:

  • Eye infection (known as endophthalmitis)
  • Cataracts can occur in one to two percent of patients up to seven years after surgery (the risk is higher in older patients with high degrees of nearsightedness)1
  • Glaucoma: Lens insertion can cause release of pigment from the iris that clogs the eye's drainage system, increases eye pressure, and leads to glaucoma
  • Retinal detachment (the risk of the retina detaching from the back of your eye is increased with any intraocular surgery)
  • Acceleration of normal corneal aging that can cause it to become cloudy2

 

ICL surgery follow-up

ICL patients should have their vision checked annually or sooner if they notice a change in their sight. Sometimes, such as with aging, patients' vision can change and they may benefit from exchanging their ICL for a different prescription lens. This procedure is done easily and with no more risk or recovery time than the original surgery.

 

Because highly nearsighted patients are the typical candidate for an ICL lens implant, their elongated eyeball shape puts them at higher risk of developing spontaneous retinal tears and also of getting cataracts.

 

As such, it is important for high myopes, including patients who have had ICL lens inserted, to have annual eye exams to monitor for the development of cataracts or retinal tears. Annual exams are important for anyone's eye health, but especially for highly nearsighted patients.
