To evaluate a new technique of 'Layer by Layer' phacoemulsification in eyes with posterior polar cataract with pre-existing posterior capsular rent (PCR).
Layer by layer phacoemulsification was performed in eight eyes of eight patients of posterior polar cataract with pre-existing posterior capsular rent. All the patients had evidence of a posterior capsular defect showing presence of iridescent refractile lens particles in vitreous with onion skinning of central dense plaque.
The mean age of the patients was 43.75+/-2.5 years and six patients were men. All the eyes had vertical posterior capsular defect irrespective of the site of entry of phaco probe. Vitrectomy was not required in any of the eyes. Single piece foldable acrylic intraocular lens was implanted in the bag in all the eyes. The mean preoperative best corrected visual acuity was 0.14+/-0.05, which improved to 0.77+/-0.27.
Our technique of 'Layer by layer' phacoemulsification is an effective and safe technique for the management of posterior polar cataract with pre-existing PCR.
评估一种用于已有后囊膜破裂(PCR)的后极性白内障患者的“逐层”超声乳化新技术。
对8例已有后囊膜破裂的后极性白内障患者的8只眼进行逐层超声乳化。所有患者均有后囊膜缺损的证据,表现为玻璃体中存在彩虹色可折射晶状体颗粒以及中央致密斑块的洋葱皮样改变。
患者的平均年龄为43.75±2.5岁,6例为男性。所有眼均有垂直后囊膜缺损,与超声乳化探头的进入部位无关。所有眼中均无需进行玻璃体切除术。所有眼均在囊袋内植入了单片可折叠丙烯酸人工晶状体。术前平均最佳矫正视力为0.14±0.05,术后提高至0.77±0.27。
我们的“逐层”超声乳化技术是治疗已有PCR的后极性白内障的一种有效且安全的技术。
