目的 了解年龄相关性白内障患者的角膜非球面因子Q值的分布情况,探讨超声乳化白内障吸除术前后角膜的非球面变化趋势.方法 前瞻性系列病例研究.选择在我院眼科住院的年龄相关性白内障患者30例(39只眼),＜1.00 D散光者取颞侧透明角膜切口,≥1.00 D散光者在最大曲率子午线作透明角膜切口行超声乳化白内障吸除术,术后3个月进行随访研究,检查项目包括手术前后的角膜Q值、平均角膜曲率、散光度数.对于手术前后角膜Q值、平均角膜曲率、散光度数进行配对t检验,对术前角膜Q值与平均角膜曲率、散光度数进行双变量相关分析.结果 手术前后的角膜Q值分别为-0.07±0.22和-0.11±0.16,均呈正态分布趋势,差异无统计学意义(t=1.14,P=0.26).手术前后的角膜曲率分别为(44.6±1.92)和(44.70±1.47)D,差异无统计学意义(t=-0.69,P=0.50);术前角膜曲率与角膜Q值成负相关(r=-0.46,P=0.003).手术前后的散光度数分别为(0.67±0.43)和(0.66±0.42)D,差异无统计学意义(t=-0.24,P=0.82);术前散光度数与角膜Q值无相关关系(r=-0.24,P=0.14).结论 老年人的角膜Q值大多为负值,呈正态分布,与角膜曲率成负相关.超声乳化白内障吸除术后的角膜Q值比术前略小,差异无统计学意义,手术前后的角膜曲率、散光度数比较差异无统计学意义.
目的 瞭解年齡相關性白內障患者的角膜非毬麵因子Q值的分佈情況,探討超聲乳化白內障吸除術前後角膜的非毬麵變化趨勢.方法 前瞻性繫列病例研究.選擇在我院眼科住院的年齡相關性白內障患者30例(39隻眼),＜1.00 D散光者取顳側透明角膜切口,≥1.00 D散光者在最大麯率子午線作透明角膜切口行超聲乳化白內障吸除術,術後3箇月進行隨訪研究,檢查項目包括手術前後的角膜Q值、平均角膜麯率、散光度數.對于手術前後角膜Q值、平均角膜麯率、散光度數進行配對t檢驗,對術前角膜Q值與平均角膜麯率、散光度數進行雙變量相關分析.結果 手術前後的角膜Q值分彆為-0.07±0.22和-0.11±0.16,均呈正態分佈趨勢,差異無統計學意義(t=1.14,P=0.26).手術前後的角膜麯率分彆為(44.6±1.92)和(44.70±1.47)D,差異無統計學意義(t=-0.69,P=0.50);術前角膜麯率與角膜Q值成負相關(r=-0.46,P=0.003).手術前後的散光度數分彆為(0.67±0.43)和(0.66±0.42)D,差異無統計學意義(t=-0.24,P=0.82);術前散光度數與角膜Q值無相關關繫(r=-0.24,P=0.14).結論 老年人的角膜Q值大多為負值,呈正態分佈,與角膜麯率成負相關.超聲乳化白內障吸除術後的角膜Q值比術前略小,差異無統計學意義,手術前後的角膜麯率、散光度數比較差異無統計學意義.

Objective To investigate the distribution of corneal Q-value in the age-related cataract patients and aspherical features of cornea before and after the phacoemulsification (PHACO).Methods Thirty-nine eyes of 30 age-related cataract patients in our department were included.Transparent cornea incision at the temporal cornea was applied for patients with cornea astigmatism ＜ 1.00 D and transparent cornea incision at the maximum curvature meridian for patients with cornea astigmatism ≥1.00 D in PHACO.All patients were followed up to 3 months,corneal Q-value,comeal curvature,astigmatism were examined before and after PHACO,distribution of corneal Q-value and their correlation factors were analyzed.Results The mean comeal Q-value before and after the PHACO was -0.07 ±0.22 and -0.11 ±0.16,respectively.There was no statistical difference between the corneal Q-values before and after surgery (t = 1.14,P = 0.26).The mean of comeal curvature before and after the PHACO was (44.6 ±1.92)D and (44.70 ± 1.47) D,respectively.There was no statistical difference between comeal curvature before and after the operation (t = -0.69,P =0.50).The corneal Q-value was negatively co-related with comeal curvature before the surgery (r = - 0.46,P = 0.003).The mean astigmatism power before and after the HACO was (0.67±0.43)D and (0.66 ±0.42)D,respectively.There was no statistical difference between astigmatism power before and after the surgery (t = -0.24,P =0.82).There was no relationship between the comeal Q-value and astigmatism power before surgery (r = - 0.24,P = 0.14).Conclusions The comeal Q-value of aged patients is in normal distribution,is negative in the majority,and showed a negative relationship with comeal curvature.There is no statistical difference between the comeal Q-value,comeal curvature,and astigmatism power before and after PHACO surgery.
