Disposable square and hexagonal Bhattacharjee pupil-expansion rings are made of 5-0 nylon, have notches at the corners, and flanges at the sides in a single 0.1 mm thin plane. To insert the ring, a flange is held with a 23-gauge forceps and the ring is inserted through a 0.9 mm (20-gauge) or larger main- or side-port incision. Alternate flanges are tucked under the iris using a Kuglen hook. A 23-gauge forceps and an iris hook can also be used to tuck the flanges bimanually. The ring is removed by disengaging 2 notches and pulling it out of a 0.9 mm (20-gauge) incision. No snagging of the incision occurs at insertion or removal. No injector is required. The device is useful in standard coaxial phacoemulsification, femtosecond laser-assisted cataract surgery, biaxial microincision cataract surgery (MICS), coaxial sub-2.0 mm MICS, and small-pupil microincision vitreous surgery and in eyes with shallow anterior chambers.
Dr. Bhattacharjee has a pending international patent application (PCT-WIPO) for the pupil-expansion devices.
一次性方形和六边形巴塔查尔吉瞳孔扩张环由5-0尼龙制成，在角落有切口，在侧面有凸缘，位于单一的0.1毫米薄平面内。为插入环，用23号镊子夹住一个凸缘，将环通过0.9毫米（20号）或更大的主切口或侧切口插入。使用库格伦钩将交替的凸缘塞入虹膜下方。也可使用23号镊子和虹膜钩双手将凸缘塞入。通过松开两个切口并将其从0.9毫米（20号）切口中拉出取出环。插入或取出时切口不会被钩住。无需注射器。该装置可用于标准同轴超声乳化术、飞秒激光辅助白内障手术、双轴微切口白内障手术（MICS）、同轴2.0毫米以下MICS以及小瞳孔微切口玻璃体手术，也适用于前房浅的眼睛。
巴塔查尔吉博士拥有一项关于瞳孔扩张装置的国际专利申请（PCT-世界知识产权组织）待批。
