Phakic lenses are produced in silicone or Collamer that are useful to correct visual defects such as nearsightedness, farsightedness, and astigmatism, even of a high degree (20-25 diopters).
They are positioned both in the anterior chamber (with an angular or iris support) and in the posterior chamber, in contiguity with the natural lens of the eye, which is the crystalline lens and have the function of modifying the path of the light rays and focusing them on the retina.
The type of implanted lens is essential for determining the quality of vision. This is why the use of Visian ICL produced by STAAR Surgical (USA) guarantees the best possible results, allowing the patient to see clearly, with greater depth and field of view.
After the posterior chamber phakic lens implantation, the patient is under rehabilitation in a maximum of 24-36 hours. It is a pain-free surgery, the quality of vision is immediately good the next day and continues to grow in the following days.
