目的：探讨如何在角膜地形图的指导下，设计个性化白内障手术方案，实现利用手术性散光矫正术前角膜散光，提高术后视觉质量，降低治疗费用的目的。<br> 方法：将202例226眼白内障患者分成随机治疗组和个性化治疗组，在随机治疗组再按手术切口的类型和位置的不同分成8组，观察术前、术后角膜散光，通过矢量分析法计算出不同手术切口的手术性散光值。个性化治疗组的手术设计以随机治疗组的各手术性散光值为参考，并以术前角膜散光与手术性散光最接近的原则选择手术切口类型，切口位置在最陡子午线上，并观察个性化治疗组术后角膜散光。<br> 结果：个性化治疗组术后角膜散光低于随机治疗组中3.0mm透明角膜隧道切口组，差异有统计学意义，与3.0mm巩膜隧道组无统计学差异，利用个性化手术方案55.8%患者可采用费用较为低廉的白内障囊外摘除加硬性人工晶状体植入术，可以降低人均治疗费用。<br> 结论：应用角膜地形图设计个性化白内障手术方案可以矫正术前角膜散光，提高视觉质量，降低治疗费用。
目的：探討如何在角膜地形圖的指導下，設計箇性化白內障手術方案，實現利用手術性散光矯正術前角膜散光，提高術後視覺質量，降低治療費用的目的。<br> 方法：將202例226眼白內障患者分成隨機治療組和箇性化治療組，在隨機治療組再按手術切口的類型和位置的不同分成8組，觀察術前、術後角膜散光，通過矢量分析法計算齣不同手術切口的手術性散光值。箇性化治療組的手術設計以隨機治療組的各手術性散光值為參攷，併以術前角膜散光與手術性散光最接近的原則選擇手術切口類型，切口位置在最陡子午線上，併觀察箇性化治療組術後角膜散光。<br> 結果：箇性化治療組術後角膜散光低于隨機治療組中3.0mm透明角膜隧道切口組，差異有統計學意義，與3.0mm鞏膜隧道組無統計學差異，利用箇性化手術方案55.8%患者可採用費用較為低廉的白內障囊外摘除加硬性人工晶狀體植入術，可以降低人均治療費用。<br> 結論：應用角膜地形圖設計箇性化白內障手術方案可以矯正術前角膜散光，提高視覺質量，降低治療費用。

AIM:To investigate how to design personalized cataract surgery programs to achieve surgical correction of preoperative corneal astigmatism with surgical astigmatism under the guidance of corneal topography, improve postoperative visual quality and reduce the cost of treatment. <br> METHODS: Totally 202 cases ( 226 eyes ) cataract patients were divided into randomized treatment group and individualized treatment group. According to the method and location of the incision, randomized treatment group were divided into 8 groups. Surgical astigmatism after different incision were calculated with the use of preoperative and postoperative corneal astigmatism through vector analysis method. Individualized treatment groups were designed personably for surgical method with reference of every surgically induced astigmatism, the surgical method chooses the type of surgical incision based on close link between preoperative corneal astigmatism and surgically induced astigmatism, and the incision was located in the steep meridian. The postoperative corneal astigmatism of individualized treatment group was observed. <br> RESULTS: Postoperative corneal astigmatism of individualized treatment group were lower than that of 3.0mm clear corneal tunnel incision in the randomized treatment group, there were statistically significance difference, while with 3. 0mm sclera tunnel incision group there were no statistically significance difference. After 55. 8% of patients with the use of individualized surgical plan could undergo the operation of extracapsular cataract extraction with relatively low cost and rigid intraocular lens implantation, the per capita cost of treatment could be reduced. <br> CONCLUSION: Personalized cataract surgery programs are designed to achieve surgical correction of preoperative corneal astigmatism under the use of corneal topography, improve postoperative visual quality and reduce the cost of treatment.
