The ICL (Implantable Contact Lens) is a highly-advanced eye treatment that can be used to treat a number of refractive errors. As the name suggests, ICL Lens Implantation involves a surgical implantation of an artificial lens which does not require regular changing like normal contact lenses. Phakic intraocular lenses (IOLs) used in Cathedral Eye Clinic offer several advantages, including the correction of severe cases of short-sightedness, long-sightedness and astigmatism.

Advanced Phakic intraocular lenses are significantly smaller than natural lenses. They are practically invisible and can be removed by your surgeon if necessary. This procedure is an attractive alternative to patients who have a high prescription or are deemed unsuitable for other procedures such as SMILE and LASIK.

Anterior chamber phakic ICLs come in two forms: iris-fixated or angle-fixated. The iris-fixated lens it attached to the iris, whilst the angle-fixated lens is rooted in position within the anterior chamber angle. Meanwhile, posterior chamber phakic ICLs are located close to the eye’s natural lens.


Implantable contact lens surgery involves the insertion of a lens into the eye, rather than removing and replacing the eye’s natural lens as seen in lens replacement surgery. Phakic IOLs are inserted over the natural lens and behind the iris, allowing for significantly improved vision results. ICL procedures are often recommended to patients under the age of 40 who do not require reading glasses.

During your procedure, your surgeon will make a small 3.5mm incision at the edge of the cornea to carefully position the ICL behind the iris and in front of the natural lens. This takes approximately 15 minutes per eye, followed by a few hours in rest to monitor the pressure of your eyes.


  • A suitable alternative: ICL Lens Implantation may be an appropriate treatment for those who may be unsuitable candidates for surgical procedures such as SMILE and LASIK (this maybe due to the patient having thin corneas or pre-existing medical conditions).
  • Quick surgery and brief recovery: Many ICL Lens Implantation patients undergo a speedy procedure and a fast recovery period, due to the small, self-healing incision that is made.
  • Less sun damage: Implantable Contact Lenses contain UV protection, reducing the likelihood of experiencing future complications as a result of sun damage.
  • Reduced dry eye symptoms: The procedure’s minimal effect upon the cornea means less complications and less postoperative dry eye symptoms.
  • Future-proof: Implantable Contact Lenses can be removed if future eye surgery is required.
