Surgical management challenges and clinical results of bimanual micro-incision phacoemulsification cataract surgery in children with congenital cataract

Abstract

Small incisions in cataract surgery have shown to reduce tissue damage, postoperative inflammation and pain. To describe in detail the surgical management challenges and clinical results of bimanual micro-incision phacoemulsification cataract surgery in children with congenital cataract. In 22 eyes of 14 children aged from 11 months to 17 years with congenital cataract, micro-incision cataract surgery with lensectomy, bimanual aspiration or phacoemulsification and implantation of an intraocular lens (SN60WF, Alcon®) was performed under general anesthesia. The visual equivalent obtained with age-related methods, the slit-lamp examination, and refractive outcome were documented in the medical records and were analyzed retrospectively. The patients fulfilled at least 3 months of follow up. In all operated eyes, micro-incision cataract surgery could be performed without serious intra-operative complications. Lensectomy was safely combined with a primary posterior capsulorhexis and anterior vitrectomy in 17 of 22 eyes. Corneal incision length ranged between 2.2 mm and 2.6 mm (mean: 2.3 ± 0.2 mm). No cases of postoperative hypotony and increased inflammation were observed. One eye required surgical removal of the after-cataract 7 months after surgery. Laser capsulotomy for posterior capsular opacification had to be performed in 2 (9 %) eyes. In all other eyes (19/22), visual axis remained clear during follow-up. Micro-incision cataract surgery is a promising alternative to conventional pediatric cataract surgery, since the technique showed to be comparably safe and effective. Longer follow-up examinations will now be performed.
