To evaluate the safety of phacoemulsification of white hypermature cataract, which is common in developing countries.
Dr. Rajendra Prasad Centre for Ophthalmic Sciences, All India Institute of Medical Sciences, New Delhi, India.
In a teaching hospital setting, a prospective evaluation of phacoemulsification in 25 eyes of 25 consecutive patients with hypermature cataract was done. Patients with good pupil dilation, optimal endothelial cell count, and disease-free ocular and systemic status were included. High magnification, sodium hyaluronate, and a Utrata capsulorhexis forceps were used to perform continuous curvilinear capsulorhexis (CCC). The stop and chop technique was used for nuclear emulsification. A 5.5 mm optic allpoly(methyl methacrylate) intraocular lens (IOL) was implanted, and wound closure was sutureless.
Successful CCC was performed in 23 of 25 cases. In 2 cases, the CCC edge extended toward the periphery and a Vannas scissors was used to achieve an even cut. No complications were seen during nuclear emulsification and IOL implantation. Eighty percent of the patients had a visual acuity of 20/40 or better on the first postoperative day. Five patients had significant corneal edema that resolved within 1 week in all cases.
Phacoemulsification was successfully and safely performed in appropriately selected patients with white hypermature cataract.
评估在发展中国家常见的白色过熟期白内障超声乳化手术的安全性。
印度新德里全印度医学科学研究所拉金德拉·普拉萨德眼科科学中心。
在一家教学医院环境中，对连续25例过熟期白内障患者的25只眼进行了超声乳化手术的前瞻性评估。纳入瞳孔散大良好、内皮细胞计数最佳且眼部和全身无疾病的患者。使用高倍放大、透明质酸钠和Utrata撕囊镊进行连续环形撕囊（CCC）。采用拦截劈核技术进行核乳化。植入一枚5.5毫米光学全聚甲基丙烯酸甲酯人工晶状体（IOL），伤口无需缝合。
25例中有23例成功完成CCC。2例中，CCC边缘向周边延伸，使用Vannas剪刀进行了均匀切割。在核乳化和IOL植入过程中未观察到并发症。80%的患者术后第一天视力达到20/40或更好。5例患者出现明显角膜水肿，但所有病例均在1周内消退。
在适当选择的白色过熟期白内障患者中，超声乳化手术得以成功且安全地实施。
