The evaluation of large series of cataract extractions is most feasible using a computer. We have computerized the details of 7503 cataract extractions (performed in the years 1961-1975). The analysis is based on a new computerreadable form. Its application is shown in two examples for comparing surgical results: 1. cataract extractions by forceps, suction cup or cryoprobe, the surgeon wearing magnifying-goggles; 2. cataract extractions by cryoprobe using the surgical microscope. The evaluation of results had been done separately for residents and experienced surgeons.
In experienced surgeons the percentage of uncomplicated extractions increased considerably with the cryoprobe (86.5%) as compared to 77% using the suction cup. The surgical microscope in that series have no significant increase of the success rate (cryoprobe 88.4%). Residents had more advantages from both technical aids: no microscope, suction cup: 73.5%, cryo: 82.5%, with microscope, cryo: 90.3%. Their results compare well with those of the experienced surgeons, since they are given straight-forward cases only and they operate under the strictest supervision of an experienced surgeon.
使用计算机对大量白内障摘除手术进行评估最为可行。我们已将7503例白内障摘除手术（于1961年至1975年间实施）的详细信息进行了计算机化处理。该分析基于一种新的计算机可读表格。其应用在两个比较手术结果的例子中得以展示：1. 使用镊子、吸盘或冷冻探头进行白内障摘除手术，外科医生佩戴放大护目镜；2. 使用手术显微镜通过冷冻探头进行白内障摘除手术。已分别针对住院医生和经验丰富的外科医生对结果进行了评估。
在经验丰富的外科医生中，与使用吸盘时的77%相比，使用冷冻探头进行的无并发症摘除手术的百分比显著增加（86.5%）。在该系列中，手术显微镜并未显著提高成功率（冷冻探头为88.4%）。住院医生从这两种技术辅助手段中获益更多：不使用显微镜，使用吸盘时为73.5%，使用冷冻探头时为82.5%；使用显微镜，使用冷冻探头时为90.3%。他们的结果与经验丰富的外科医生的结果相当，因为他们仅被给予简单病例，且在经验丰富的外科医生的严格监督下进行手术。
