This report describes a 1-handed technique and a 2-handed technique anterior capsulotomy in pseudophakic eyes. Each technique was used in a case of proliferative vitreoretinopathy accompanying anterior capsule contraction that occurred following cataract and intraocular lens (IOL) implantation. A capsulorhexis forceps and a stab knife were inserted into the anterior chamber, and the capsule contraction alleviated without extracting the IOL in both cases. Secondary anterior capsulotomy contributed to both the surgeon's visibility during intraocular surgery, including the subsequent vitreous surgery, and the patient's postoperative visual acuity. The transparency of the pupil region was restored. While the 1-handed technique involves the risk of adversely affecting Zinn's zonule, the 2-handed technique does not place a burden on Zinn's zonule and is thought to considerably improve the surgeon's visibility in subsequent vitreoretinal surgery.
本报告介绍了在人工晶状体眼发生白内障和人工晶状体（IOL）植入术后前囊收缩伴增生性玻璃体视网膜病变的情况下，采用单手技术和双手技术进行前囊切开术。在这两种情况下，均使用撕囊镊和穿刺刀插入前房，在不取出 IOL 的情况下缓解了前囊收缩。二次前囊切开术有助于提高眼内手术（包括随后的玻璃体手术）期间的术者可视度，并提高患者术后视力。瞳孔区的透明度得到恢复。单手技术可能对 Zinn 悬韧带产生不利影响，而双手技术则不会对 Zinn 悬韧带造成负担，并且可以大大提高术者在随后的玻璃体视网膜手术中的可视度。
