We retrospectively examined the effect of air, as contrasted with balanced salt solution (BSS), sodium hyaluronate, or no substance at all, used to reform the anterior chamber at the end of trabeculectomy on subsequent cataract formation in 141 consecutive patients (173 phakic eyes). The minimum follow up was 120 days. The use of air increased the incidence of anterior subcapsular cataract formation significantly. Also, the eyes that had a large air bubble on postoperative day 1 had a higher incidence of anterior subcapsular cataract than the eyes with less air on that day. We suggest that the toxicity to the lens of the oxygen in the air increased the incidence of anterior subcapsular cataract in the eyes in which air was used. We recommend that BSS or sodium hyaluronate be used instead of air to reform the anterior chamber following trabeculectomy.
我们回顾性研究了在小梁切除术结束时，使用空气与平衡盐溶液（BSS）、透明质酸钠或不使用任何物质来重建前房，对141例连续患者（173只晶状体眼）随后发生白内障的影响。最短随访时间为120天。使用空气显著增加了前囊下白内障形成的发生率。此外，术后第1天有大气泡的眼睛比当天气泡较少的眼睛发生前囊下白内障的发生率更高。我们认为，空气中的氧气对晶状体的毒性增加了使用空气的眼睛中前囊下白内障的发生率。我们建议在小梁切除术后使用BSS或透明质酸钠代替空气来重建前房。
