【摘要】 目的:比较Wang-Koch眼轴矫正公式SRK/T_WK、HolladayⅠ_WK与SRK/T、Haigis、HolladayⅠ、Hoffer Q公式计算高度近视并发白内障患者术后屈光度的准确性。方法:选取2019-09/2022-03于我院行白内障超声乳化摘除联合人工晶状体植入术的高度近视合并白内障患者42例57眼，根据眼轴长度（AL）分为A组（27mm≤AL<30mm, 31眼）和B组（AL≥30mm, 26眼）。术后3mo随访，记录实际屈光度，计算平均屈光误差（MNE）和平均绝对屈光误差（MAE）。结果:纳入患者术后各公式MAE有明显差异（P<0.01）,其中HolladayⅠ_WK和SRK/T_WK公式术后MAE[0.31（0.08,0.57）、0.34（0.17,0.63）D]均较其余各公式低，但与SRK/T、Haigis公式[0.61（0.27,1.02）、0.63（0.22,1.01）D]均无明显差异（P>0.05）。A组患者（27mm≤AL<30mm）术后各公式MAE有明显差异（P<0.01）,其中HolladayⅠ_WK和SRK/T_WK公式术后MAE[0.18（0.05,0.51）、0.28（0.16,0.52）D]均较其余各公式低，但与SRK/T、Haigis公式[0.45（0.18,0.65）、0.50（0.14,0.75）D]均无明显差异（P>0.05）;B组患者（AL≥30mm）术后各公式MAE有明显差异（P<0.01）,其中HolladayⅠ_WK、SRK/T_WK公式术后MAE最低，SRK/T和Haigis公式术后MAE较大，HolladayⅠ和Hoffer Q公式术后MAE最大，且SRK/T_WK、HolladayⅠ_WK公式术后MAE[0.44（0.23,0.67）、0.41（0.22,0.66）D]与SRK/T、Haigis公式[0.78（0.55,1.07）、0.75（0.45,1.25）D]有明显差异（均P<0.05）。结论:两种Wang-Koch眼轴矫正公式计算AL≥30mm的高度近视合并白内障患者人工晶状体屈光度相对准确，具有一定的临床应用价值。更多还原

【Abstract】 ?AIM: To compare the accuracy between Wang-Koch axial length adjustment formulas(SRK/T_WK, Holladay Ⅰ_WK) and SRK/T, Haigis, Holladay Ⅰ, Hoffer Q in calculating intraocular lens power of cataract patients with high myopia.?METHODS: A total of 42 cataract patients with high myopia（57 eyes） were collected. All eyes underwent phacoemulsification combined with intraocular lens implantation surgery in our Hospital from September 2019 to March 2022. They were divided into two groups according to the axial length（AL）: group A（27mm≤AL<30mm, 31 eyes） and group B（AL≥30mm, 26 eyes）. Patients were followed up at 3mo. The actual postoperative diopter was recorded, and then the refractive mean numerical error（MNE） and mean absolute error（MAE） were calculated.?RESULTS: MAE of each formulas was statistically different after surgery（P<0.01）, among which the MAE of Holladay Ⅰ_WK and SRK/T_WK [0.31（0.08, 0.57）, 0.34（0.17, 0.63） D] was lower than other formulas. However, there were no statistical difference between SRK/T_WK, Holladay Ⅰ_WK and SRK/T, Haigis formulas [0.61（0.27, 1.02）, 0.63（0.22, 1.01） D]（P>0.05）. MAE were statistically different among the formulas in group A（27mm≤AL<30mm; P<0.01）. The MAE of Holladay Ⅰ_WK and SRK/T_WK was lower than other formulas [0.18（0.05, 0.51）, 0.28（0.16, 0.52） D], but there were no statistical difference with SRK/T and Haigis formulas [0.45（0.18, 0.65）, 0.50（0.14, 0.75） D]（P>0.05）. In group B（AL≥30mm）, the MAE of each formulas was statistically different after surgery（P<0.01）, among which MAE of Holladay I_WK and SRK/T_WK was the lowest, followed by SRK/T and Haigis, whereas, Holladay I and Hoffer Q ranked the highest. Furthermore, there were statistical differences between MAE of SRK/T_WK, Holladay Ⅰ_WK [0.44（0.23, 0.67）, 0.41（0.22, 0.66） D] and SRK/T, Haigis formulas [0.78（0.55, 1.07）, 0.75（0.45, 1.25） D]（all P<0.05）.?CONCLUSION: For cataract patients with AL ≥30mm, the Wang-Koch axial length adjustment formulas were relatively accurate in calculating diopter of intraocular lens, and had clinical application value to some extent.更多还原
