Congenital Cataract Clinical Trial
Official title:
A Novel Prophylactic Peripheral Iridectomy Prevents Aphakic Angle-closure Glaucoma After Congenital Cataract Surgery
This is a retrospective, nonrandomized comparative trial with historical control to investigate the safety and efficacy of a novel progressive grasping peripheral iridectomy (PGPI) surgical method in preventing aphakic angle-closure glaucoma (AACG) following congenital cataract surgery.
Aphakic angle-closure glaucoma (AACG) following congenital cataract surgery is a common and
serious complication which can be prevented by prophylactic peripheral iridectomy (PPI).
However, it is difficult to perform routine PPI via scleral tunnel incision especially when
the pupil is dilated. Here, the investigators designed a novel progressive grasping
peripheral iridectomy (PGPI) surgical method which can ensure the accurate iridectomy
position and minimize the complication. The aim of this study is to assess the safety and
efficacy of the PGPI in preventing AACG following congenital cataract surgery.
This is a retrospective, nonrandomized comparative trial with historical control. The
congenital cataract patients performed with cataract extraction combined with PPI (PPI group)
and the patients performed with cataract extraction alone and leaving the iris intact
(historical control group) were enrolled and a retrospective medical chart review was
conducted. The IOP, anterior chamber depth, corneal clarity, patency of peripheral iridectomy
opening, and the rate of AACG, iris posterior synechia (IPS) and visual axis opacity (VAO)
were compared between two groups.
