[Treatment of congenital cataract with McIntyre co-axial I.A. cannula]

Thirty seven eyes with congenital cataract in with there a lot of transparent cortex were treated with McIntyre co-axial cannula. Primary posterior capsuloctomy after removing the cortex was performed on patients aged less 3 years; for patients over 3 years, their posterior capsule remained intact. After the operation, all cases got transparent pupillary space more than 5 mm in diameter. The visual acuities improved in 32 eyes and remained unchanged in 5 eyes. This procedure not only received satisfactory results, but also avoided side effects caused by capsuloctomy and reduced the possibility of general anesthesia accident and operation fee.
