A 3-step technique for staining the anterior lens capsule was developed to optimize the use of a capsule dye (trypan blue or indocyanine green) during capsulorhexis. After the injection of a viscoadaptive ophthalmic viscosurgical device (OVD) (sodium hyaluronate 2.3% [Healon 5]), which fills the anterior chamber, balanced salt solution (BSS) is gently injected onto the anterior capsule, creating a wafer-thin, fluid-filled space beneath the OVD. The dye is slowly injected through a 27-gauge cannula (Duckworth & Kent), selectively mixing with the BSS and allowing relatively accurate painting of the anterior capsule, approximating the size and shape of the intended capsulorhexis. This 3-step technique avoids the use of air as well as the uncontrolled dispersion and excessive accumulation of dye within the OVD.
我们开发了一种三步技术用于前囊染色，以在撕囊过程中优化囊染料（台盼蓝或吲哚菁绿）的使用。在注入填充前房的粘弹性眼科手术装置（OVD）（2.3%透明质酸钠[Healon 5]）后，将平衡盐溶液（BSS）轻轻注入前囊上，在OVD下方形成一个薄如晶片、充满液体的空间。染料通过27号套管（Duckworth & Kent）缓慢注入，与BSS选择性混合，从而能相对准确地涂抹前囊，使其接近预期撕囊的大小和形状。这种三步技术避免了使用空气以及染料在OVD内不受控制的扩散和过度积聚。
