Retina · Retinal surgery
Secondary IOL implantation refers to the placement of an intraocular implant at a second stage, when the eye has none or when the previous implant must be replaced. It restores the eye's optical correction.
Normally, the implant that corrects vision is placed during cataract surgery, as a replacement for the natural lens. Secondary implantation refers to the placement of this implant at a later stage, after the original procedure: either because no implant could be placed at the time, or because the previous implant must be removed and replaced.
The aim is to restore the eye's optical correction. Since the implant cannot always rest on its natural support, it is sometimes sutured to the wall of the eye: this is specialised surgery.
Secondary implantation completes or corrects a previous situation: it is carefully planned from a thorough assessment of the eye.
Secondary implantation may be indicated in particular:
A thorough assessment determines the condition of the eye, the presence or absence of implant support, and the state of the retina. It allows the most appropriate implant type and fixation technique to be selected. This is where Dr Gattoussi's expertise in retinal surgery and ocular imaging is particularly valuable.
The procedure involves placing an implant, fixed using a technique chosen according to the anatomy of the eye. Depending on the situation, the implant may be fixed to the iris (the coloured part of the eye) or to the sclera (the white part). This is specialised surgery, planned on the basis of the pre-operative assessment.
Evaluation of the support, the retina, and implant power calculation.
Implant type and fixation method suited to the anatomy.
Placement and fixation of the implant during the procedure.
Check-ups to verify implant stability and recovery.
Recovery depends on the technique used and the condition of the eye. Eye drops are prescribed and close follow-up is arranged to monitor healing and the stability of the implant.
Because no implant could be placed during the initial procedure, or because an implant needs to be replaced (for example after dislocation).
The fixation technique is chosen to ensure its stability. Regular follow-up verifies this.
The aim is to restore the eye's optical correction. Recovery depends on the condition of the eye and is assessed on a case-by-case basis, with no guarantee of outcome.
