A series of 55 small incision (3 mm) silicone-implanted cataract cases closed with horizontal sutures and a concurrent series of 48 6 mm to 7 mm incision poly(methyl methacrylate)-implanted cases closed with radial incisions were compared retrospectively for surgically induced astigmatism. At two to three weeks after surgery, the mean surgically induced astigmatism in the poly(methyl methacrylate) group was more than twice as high as in the silicone group (2.27 D vs 1.07 D, P less than .01). In addition, a series of 41 small incision cases and a concurrent series of 61 cases with 6 mm to 7 mm incisions were compared for inflammation as measured by an FC-1000 laser flare/cell meter. The larger incision cases had significantly higher average cell counts at one day and one week postoperatively (P = .005 and P = .03, respectively) and had significantly higher average flare measurement at one day (P = .01) than the smaller incision cases.
回顾性比较了一系列55例采用水平缝合关闭切口的3毫米小切口硅胶植入白内障病例，以及同时期48例采用放射状切口关闭切口的6至7毫米切口聚甲基丙烯酸甲酯植入病例的手术源性散光情况。术后两到三周，聚甲基丙烯酸甲酯组的平均手术源性散光比硅胶组高出两倍多（2.27 D对1.07 D，P小于0.01）。此外，比较了一系列41例小切口病例和同时期61例6至7毫米切口病例，通过FC - 1000激光光斑/细胞计数仪测量炎症情况。大切口病例术后一天和一周的平均细胞计数显著更高（分别为P = 0.005和P = 0.03），且术后一天的平均光斑测量值也显著高于小切口病例（P = 0.01）。
