We sought to determine whether maintaining nearly physiologic levels of intraocular pressure (IOP) before the final tying of sutures in cataract surgery can help minimize postoperative-induced astigmatism. We compared the postoperative astigmatic decay curves of two similar groups of 18 patients who had undergone cataract surgery, in one of which IOP had been maintained at 17 mm Hg prior to the final tying of sutures, and in the other of which the eyes were hypotonus (3 mm Hg) at this point. Initial with-the-rule cylinder change was significantly less and astigmatic decay occurred earlier in the former group.
我们试图确定在白内障手术最后打结缝线之前维持接近生理水平的眼压（IOP）是否有助于将术后诱导性散光降至最低。我们比较了两组各18例接受白内障手术的相似患者的术后散光衰减曲线，其中一组在最后打结缝线前眼压维持在17 mmHg，另一组此时眼压过低（3 mmHg）。前一组的初始顺规柱镜变化明显较小，且散光衰减出现得更早。
