Clinical Characteristics and Surgical Safety in Congenital Cataract Eyes with Three Pathological Types of Posterior Capsule Abnormalities

Figure 1

Main operative steps for 3 types of posterior capsule abnormalities (PCAs) in congenital cataract (CC) eyes. (a–c) are for persistent fetal vasculature (PFV). (a) A preoperative view; (b) after the anterior capsulotomy and major cortex removing with vitrector, the fetal vessels (yellow arrows) and the central dense plaque opacity were present clearly; (c) it was left aphakia after lensectomy combined with posterior capsulotomy and anterior vitrectomy. (d–f) are for posterior capsule defect (PCD). (d) A preoperative view; (e) a large and irregular preexisting PCD (yellow arrows) was shown after anterior capsulotomy and central cortex removed with vitrector; (f) the irregular PCD was trimmed to be a round one and followed by the anterior vitrectomy without primary intraocular lens (IOL) implantation. (g–i) are for posterior lenticonus (PLC). (g) A preoperative view; (h) the huge PLC (yellow arrows) turned up after the anterior capsulotomy and cortex removed with vitrector; (i) a single-piece IOL was implanted in the capsule bag which was followed by the capsulotomy of PLC and anterior vitrectomy.
