据随机抽样原则，对巩膜池成形小梁切除术与Ｃａｉｒｎｓ小梁切除术各３２眼的远期疗效进行了对比。结果显示：Ｃａｉｒｎｓ小梁切除术后平均随访５４．３月，平均眼压２．６４ｋＰａ（２０．３ｍｍＨｇ），平均房水流畅系数０．２１２Ｃｕｍｍ／ｍｉｎ／ｍｍＨｇ；巩膜池成形小梁切除组术后平均随访５３．８月，平均眼压２．０２ｋＰａ（１５．５ｍｍＨｇ），平均房水流畅系数０．２８０Ｃｕｍｍ／ｍｉｎ／ｍｍＨｇ。两组数据经统计学处理，Ｐ＜０．０１，证实巩膜池成形小梁切除术的降压效果及房水滤过作用均优于Ｃａｉｒｎｓ小梁切除术，是一种较理想的抗青光眼手术方式。
According to the principle of random sampling, the long-term efficacy of scleral pool-forming trabecular surgery and Cairns trabeculectomy in each of the 32 eyes was compared. The results showed that: average follow-up after Cairns trabeculectomy 54.3 months, the average IOP 2.64kPa (20.3mmHg), the average coefficient of aqueous fluid smoothing 0.212Cumm / min / mmHg; scleral pool forming trabecular surgery group The average follow-up 53.8 months, the average IOP 2.02kPa (15.5mmHg), the average coefficient of aqueous fluid smoothing 0.280Cumm / min / mmHg. The two groups of data by statistical analysis, P <0.01, confirmed that the scleral buckling tracheostomy hypotensive effect and aqueous filtration were better than Cairns trabeculectomy, is a more ideal anti-glaucoma surgery the way.
