438 eyes of 365 patients undergoing Extra-Capsular Catarct Extraction were included in this study. Preoperatively the age of the patients, colour of the nucleus and grading on the Wilmer System were recorded. Postoperatively the diameter, width and hardness of the nucleus were recorded. Statistical analysis revealed a strong correlation between the age, depth of colour and grading on the Wilmer system and the size and hardness of the nucleus. The size and hardness of the nucleus can be predicted preoperatively by proper assessment of the age, colour, and grading on the Wilmer System. This would help the Surgeon in evolving a proper surgical plan for each patient and thus bringing down the complication rate and difficulties faced during the surgery especially during Phacoemulsification surgeries.
本研究纳入了365例行白内障囊外摘除术患者的438只眼。术前记录患者年龄、晶状体核颜色及威尔默系统分级。术后记录晶状体核的直径、宽度和硬度。统计分析显示，年龄、晶状体核颜色深度、威尔默系统分级与晶状体核大小和硬度之间存在强相关性。通过对年龄、颜色及威尔默系统分级进行适当评估，可在术前预测晶状体核的大小和硬度。这将有助于外科医生为每位患者制定合适的手术方案，从而降低并发症发生率以及手术过程中尤其是超声乳化手术时面临的困难。
