After the ultrasonic tip is introduced into the highly myopic eye and inflow is activated, the anterior chamber deepens, the lens-iris diaphragm is displaced posteriorly, the iris becomes concave, and the pupil dilates from the weight of the water column above the eye. We define a known but undescribed syndrome--the lens-iris diaphragm retropulsion syndrome (LIDRS)--which is thought to be caused by abnormally loose zonules. The surgeon's reflexive action, lowering the infusion bottle height, reduces the weight of the water column but also reduces the infusion limit. We managed this situation with an inflow-splitting technique in which the infusion bottle height was lowered significantly and a Lewicky chamber maintainer connected to a second infusion bottle at the same height as the first bottle was introduced into the anterior chamber. Pressure monitoring that enabled simultaneous, synchronized recording of phacoemulsification and intraocular pressure fluctuations was used.
将超声探头插入高度近视眼中并启动灌注后，前房加深，晶状体 - 虹膜隔向后移位，虹膜变得凹陷，且由于眼上方水柱的重量瞳孔散大。我们定义了一种已知但未描述过的综合征——晶状体 - 虹膜隔后推综合征（LIDRS），认为它是由异常松弛的悬韧带引起的。外科医生的本能反应，即降低输液瓶高度，虽减轻了水柱重量，但也降低了灌注极限。我们采用一种分流灌注技术来处理这种情况，即大幅降低输液瓶高度，并将与第二个输液瓶相连且高度与第一个输液瓶相同的Lewicky前房维持器引入前房。使用了能够同时、同步记录超声乳化和眼内压波动的压力监测设备。
