Abstract Details

Purpose:

To report the rate and reasons of secondary surgery in 76 eyes implanted with the "Bag-In-the-Lens" (BIL) fixation.

Setting:

Caen University Hospital, Department of Ophthalmology, Caen, France

Methods:

This retrospective study included children younger than 16 years old with primary BIL implantation from 2009 to 2019, with a minimal 3-month follow-up. There were no exclusion criteria. The patients of three different surgeons have been included. The BIL implantation consist of the creation of a posterior continuous curvilinear capsulorhexis equal in size to the anterior capsulorhexis. Both anterior and posterior capsulorhexis are inserted in the interhaptic groove of the BIL, ruling out lens epithelial cells growth.

Results:

76 eyes of 61 children were enrolled: 46 unilateral, 30 bilateral cataracts. Mean age at surgery was 5.98 years (+/- 5,02 SD). Mean follow-up was 3.27 years (0,25-9,40 years). BIL implantation was feasible in 90.5%. Nine reoperation occurred: four anterior vitrectomies for visual axis opacification (VAO) (5.2%), one anterior vitrectomy for anterior luxation, one posterior vitrectomy and one scleral buckling for retinal detachments and two iris capture relief. Mean time interval of reoperation was 1.27 years (0,01-4,00 years). A clear visual axis was maintained in 94.8% of the children. No children required intraocular pressure lowering treatment or glaucoma surgery.

Conclusions:

BIL implantation in pediatric eyes showed a low rate of reoperation thanks to fewer post-operative complications. The prevalence of posterior capsule opacification tends to be close to 0% if both capsulorhexis are well calibrated and if the BIL implant is well positioned in both capsules. This surgical step is crucial because it also explains the decrease in postoperative inflammation and secondary glaucoma. In Caen, the BIL implantation technique is become through the past ten years the preferred technique used in paediatric cataract surgery.
