Abstract

OBJECTIVE:

Evaluate the advantages of the bag-in-the-lens intraocular lens in children undergoing cataract surgery.

PATIENTS AND METHODS:

This prospective study included 54 eyes of 37 children and babies (age, 2 months to 14 years), consecutively operated on between December 1999 and January 2008 for unilateral or bilateral cataract using the "bag-in-the-lens" intraocular lens. Slit-lamp examination, intraocular pressure, visual acuity, and refraction were followed to the best possible degree over time.

RESULTS:

The mean age of the 37 children at the last consultation visit was 8.3+/-4.9 years. The mean visual acuity improved from 0.2+/-0.1 to 0.8+/-0.3. On the other hand, visual acuity improvement in children presenting hyperplastic persistence of the vitreous was less favorable with a postoperative average visual acuity of 0.14+/-0.18. The mean postoperative refraction in 13 children (26 eyes) operated on for bilateral cataract was 0.5+/-1.5 D for eyes showing axial lengths with substantial variation. The refraction was stable over time in children over 2 years of age. Once the implant was positioned correctly, the remaining epithelial cells of the lens did not migrate toward the visual axis, which was the case in 93.8% of all eyes and in 100% of children over 1 year of age.

CONCLUSIONS:

The "bag-in-the-lens" implant is particularly indicated in children in whom posterior rhexis and optic capture have been recommended since 1994. The implantation minimizes the use of anterior vitrectomy in pediatric cataract surgery, limiting it to those eyes presenting a proliferative hyperplastic vitreous.
