Phakic IOL - The Implantable Contact Lens

An expert in the treatment of high myopia, Allon Barsam has extensive research and practical expertise with this technology.


Also known as the implantable contact lens or implantable collamer lens (ICL), this procedure is useful for patients under the age of 45 in whom laser vision correction is not indicated, due to conditions such as untreatable dry eyes, thin corneas or where the patient’s glasses prescription falls outside of the range of what can/should be safely and effectively treated (-10.0 to +4.0). The advantage of the phakic IOL procedure over refractive lens exchange surgery is that the patients retain the natural focusing ability of the eye. The advantage of this procedure over laser eye surgery is that no corneal tissue is removed and it is completely reversible.

Allon Barsam has been instrumental in carrying out research into phakic IOLs to show which patients benefit the most from this treatment and what the safety considerations are. He has been invited to speak all over the world on this technology and his research on this has been featured in many international press articles which can be accessed here.

The Phakic IOL procedure is carried out as a day case under local anaesthetic drops and is not painful. The lens is implanted through a keyhole microscopic sutureless corneal incision and typically takes 10-15 minutes to perform.

Once the implant is in place, it cannot be felt by the patient or seen by others and it does not cause rejection as it is made of an inert material.
