中文摘要 | 以Scheimpflug photography眼前部分析儀測量四十名白內障病 人在接受超音波乳化術前後的前房隅角角度 (anterior chamber angle) 和前房深度 (anterior chamber depth) 的變化。 依植入人工水晶體的不同, 分成硬式 polymethyl methacrylate (PMMA) 組和軟式可折疊 Silicone 組,並分別在術後檢查不同人工晶體的穩 定性。 結果顯示:術前 PMMA 組的平均前房鼻側隅角為 28.31 ± 5.59 °,術後八週平均 角度為 39.23 ± 6.09 °,而平均前房顳側隅角為 27.83 ± 6.50 °,術後八週平均角度 為 37.29 ± 4.89 °; 術前平均前房深度為 2.66 ± 0.42mm,術後八週平均深度為 3.92 ± 0.34mm。 不論 PMMA 組或是 sILICONE 組在術後一週、術後八週的前房隅角都有明顯變 寬變大的現象,而前房深度也有意義的變深。但是不論術前或術後 PMMA 組和 Silicone 組 都沒有統計學上的差異。這方面對於青光眼病人接受白內障年術應有正面的意義。 PMMA 人 工水晶體組在術後八週時平均傾斜度為 2.57 ± 1.34 °, 平均中心移位 0.41 ± 0.18mm ; Silicone 組則平均傾斜度為 4.25 ± 2.37 °, 平均中心移位為 0.72 ± 1.04mm。 Silicone 組是否較易傾斜及中心移位,有待進一步更多病例的收集和探討。 |
英文摘要 | We measure the change of ant. chamber angle and depth in 40 patients with cataracts by Scheimpflug photography--"Ant. segment analysis of eye" before and after phacoemulsification. There are two groups depending on the types of IOL in our study--"hard PMMA" and "soft foldable silicon" ILO, and we examine the stability of them after cataract surgery. The result indicates the average nasal ant. Chamber angle of PMMA group is 28.31 ± 5.59 ° before surgery; 39.23 ± 6.09 ° in 8 weeks after surgery. The average temporal ant. chamber angle is 27.83 ± 6.50 ° before surgery; 37.29 ± 4.89 ° in 8 weeks after surgery. The average ant. chamber depth of PMMA group is 2.66 ± 0.42 mm before surgery; 3.92 ± 0.34 mm in 8 weeks after surgery. The ant. chamber angle and depth of two groups both increase significantly in one and eight weeks after surgery. But there are no significant statistical differences between PMMA group and silicone group. This result should be positive for patients with glaucoma ma to receive cataract surgery. The average tilt of IOL in PMMA group is 2.57 ± 1.34 ° in 8 weeks after surgery, and the average decentration of IOL is 0.41 ± 0.18 mm; the average tilt of IOL in silicon group is 4.25 ± 2.37 ° in 8 weeks after surgery, and the average decentration of IOL is 0.72 ± 1.04 mm. However, we need more cases collected and discussed to know whether tilt and decentration occur more commonly in silicon IOL or not. |
