Permanent lenses advantages and disadvantages 

Permanent lenses for eyes are artificial lenses that are implanted in the eye to treat vision problems. One type of permanent lens is the implantable collamer lens(ICL). Another type of lens is the permanent contact lens. Both types of lenses require surgery, but they can be removed if needed. 

On the other hand, Implantable contact lenses (ICL) and implantable collamer lenses (ICL) are two terms for the same type of lens. They are both posterior chamber phakic intraocular lenses that are implanted inside the eye, between the iris and the natural lens, to correct refractive errors. They are made of a biocompatible material called Collamer, a blend of polymer and collagen.

Implantable contact lenses (ICL) could be a safe option for you if you have issues such as Myopia, hyperopia, or astigmatism. You might want to get an expert opinion from a manhattan implantable contact lens (icl).


Permanent lenses help the patient improve his vision along with many more benefits, such as ;

  • ICL is known to fix severe nearsightedness 
  • ICL does not cause dry eyes like other lenses and is ideal for people with chronic dry eyes.
  • ICL is permanent but can be removed if wanted.
  • ICL provides great night vision.
  • Recovery is usually quick because the tissue is not removed.
  • ICL can be performed on people who cannot get laser eye surgery.


Like any surgery, ICL also has certain complications.

  • It can increase pressure in your eye if it is not correctly positioned. This can lead to glaucoma.
  • If you have high eye pressure for a long period, you might experience vision loss.
  • ICL can increase the risk of cataracts as it can decrease fluid circulation in the eye, which could also be a risk caused by sizing issues during the procedure. ICL can cause chronic eye inflammation. 
  • ICL could cause Blurry vision, glare, or double vision if the lens is not the right size. These are also the symptoms of cataracts and glaucoma. 
  •  ICL could cause Cloudy cornea.  Any eye surgery performed at an older age reduces endothelial cells in the cornea. If the cells decrease fast, the patient may develop a cloudy cornea.
  • ICL can cause retinal detachment. Retinal detachment is a usual risk with eye surgeries. If occurred the patient will need immediate medical attention. 
  • ICL increases the risk of eye infection. Like any eye surgery, ICL also has the risk of eye infection, which can also cause permanent vision loss.
  • If there has been a risk or mishap after the surgery, there is a chance for additional surgery where the lens has to be removed and placed again.
