Discover how to correct your visual defect with intraocular refractive surgery
What they are
In cases where laser corneal surgery cannot be implemented, it is possible to insert a phakic intraocular lens, i.e. with no extraction of the crystalline lens. The lenses are designed and realised in a personalised way, after performing specific pre-operational exams to obtain precise measurements of: the internal spaces of the eye, the gravity of the visual defect and the number of endothelial cells that protect the cornea inside the eye. The phakic lens can be placed: in the anterior chamber, in front of the pupil; in the posterior chamber, behind the pupil, between the iris and the crystalline lens. The implant procedure occurs under topical anaesthesia with a small incision that does not require surgical sutures. Usually an eye after the other is operated, even if the second operation is scheduled the following day or after a few days. This kind of operation is generally characterised by a high quality optical result, also in correcting serious defects.
