Bag-in-the-lens technique shows no secondary opacification at 2 years in series of pediatric patients

COPENHAGEN, Denmark — Good, stable results and no secondary opacification were reported in a series of children implanted with the bag-in-the-lens method at a pediatric eye clinic in Ukraine.
The bag-in-the-lens technique entails the creation of a twin capsulorrhexis in the anterior and posterior capsules. A specially designed IOL that clasps the remaining capsular bag between circumferential haptic rims is then implanted.
Nineteen children between the ages of 2.5 years and 18 years were followed after surgery with bag-in-the-lens implantation for various types of congenital and traumatic cataract. At 2 years, the optical axis was transparent in all cases.
"A white rim of fibrosis was seen around the edge of the twin capsulorrhexis, embracing the IOL. No lens epithelial cell proliferation was visualized biomicroscopically in the visual axis," Nadiya F. Bobrova, MD, said at the meeting of the European Society of Ophthalmology.

This was remarkable, she noted, because after-cataract develops in up to 94% of pediatric cases in the first year after surgery due to the high regenerative capacity of the equatorial lens epithelial cells.
The fibrotic rim, on the other hand, enhanced IOL stability.
"No trembling, displacement or decentration was seen during eye movements," Bobrova said.
