Posterior Capsular Opacification Eradication With Bag in the Lens IOL Implantation: 4-Year Follow-up Results of French Experience
Purpose
To study the rate of posterior capsular opacification (PCO) with the Bag in the Lens (BIL) implantation technique, comparing to the usual known data of in-the-Bag IOLs. To evaluate the feasibility of this technique, that needs anterior and posterior capsulorhexis, in routine cataract surgery.
Methods
In a retrospective study, the authors recalled all patients operated with BIL implantation more than four years ago. All patients receiving a BIL lens were included. 115 patients were able to be examined. The status of the visual axis (absence or presence of PCO, ndYAG treatment) has been checked. Adverse events were also studied, as complications like cystoïd macular edema, retinal detachment, endophthalmitis, IOL displacement or dislocation.
Results
No case of PCO was observed in our patients. not only the visual axis remained clear, but the whole posterior surface of the 5mm diameter optic. Closure of the equator of the capsular bag leads to a lack of fibrosis formation, and a very few amount of equatorial epithelial cells proliferation at four years. No late dislocation occurred, no endophthalmitis. One retinal detachment occurred. The rate of CME was not different as usual.
Conclusion
The aim of eradication of PCO is obtain with the BIL technique in cataract surgery. Adverse side effects are low. This technique of implantation can be recommended in adults, but also very interesting in pediatric surgery.
