Abstract Details

Purpose:

To compare the feasibility and interest of the bag-in-the-lens (BIL) versus standard (bag or sulcus or posterior optic capture) intraocular lens (IOL) implantation in congenital cataract with a long-term follow-up.

Setting:

Caen University Hospital, Department of Ophthalmology, Caen, France

Methods:

This cohort included all the children having a congenital cataract and planned for surgery between December 2008 and December 2013 at Caen University Hospital, France.

Results:

Thirty eyes of 21 children achieved a complete follow-up of 5 years or more. Nine children had bilateral cataract and 12 had unilateral cataract. Among bilateral cataract, 100% (13/13) eyes implanted with a BIL IOL achieved a visual acuity of 0.0 logMAR at 5 years versus 40% (2/5) eyes implanted with a standard IOL (p=0.012). Among unilateral cataract, mean visual acuity was 0.33 +/- 0.21 logMAR in the BIL IOL group versus 0.73 +/- 0.79 logMAR in the standard IOL group (p=0.51). A clear visual axis was maintained in 90.4% of cases implanted with a BIL IOL versus 55% of cases implanted with a lens-in-the-bag or sulcus IOL. An anterior vitrectomy was carried out in 28.5% (6/21) of the eyes implanted with a BIL IOL versus 66.6% (6/9) of the eyes implanted with a standard IOL. No eye developed glaucoma in either group during the follow-up period.

Conclusions:

When compared to standard IOL implantation, the BIL implantation technique in children helps avoids visual axis reopacification, leads to better visual outcomes and could help avoid glaucoma.
