In the presence of proliferations anteriorly, adequate excision of the vitreous base is essential. To enable a good vitreous base excision, removal of lens often becomes necessary as it may be damaged while attempting to remove peripheral vitreous. To avoid damage or the need to remove the crystalline lens we have used a new modified curved vitreous cutter along with a wide angle observation system binocular indirect ophthalmomicroscope (BIOM). Use of BIOM during vitreous surgery enables easy viewing of the retinal periphery without the need for scleral depression. Sclerotomies are made as for any regular three-port vitrectomy procedure and the vitrectomy is carried out using the curved vitreous cutter, including the vitreous base, avoiding damage to the crystalline lens. The modified curved vitreous cutter is helpful in removing the peripheral vitreous without damaging the crystalline lens, giving the patient the advantage of intraocular lens implantation at a later date.
当眼前部存在增殖时，充分切除玻璃体基底部至关重要。为了能够良好地切除玻璃体基底部，通常需要摘除晶状体，因为在试图切除周边玻璃体时晶状体可能会受到损伤。为避免损伤或摘除晶状体，我们使用了一种新型改良弯曲玻璃体切割器以及广角观察系统双目间接检眼镜（BIOM）。在玻璃体手术中使用BIOM能够轻松观察视网膜周边部，而无需进行巩膜压迫。按照常规三通道玻璃体切除术的方法制作巩膜切口，并使用弯曲玻璃体切割器进行玻璃体切除，包括玻璃体基底部，避免损伤晶状体。改良弯曲玻璃体切割器有助于在不损伤晶状体的情况下切除周边玻璃体，为患者日后植入人工晶状体提供了便利。
