目的:探讨近视屈光矫正术后白内障手术时间、屈光状态的改变以及人工晶体度数选择的可靠性。方法:经RK、PRK、ALK、LASIK治疗后的白内障病人6例（9只眼）行白内障超声乳化摘除联合人工晶体植入术,选用经SRK三元回归公式自动计算的近正视化或近视（-5.00D）的人工晶体,随访3月～3年对白内障术前和术后的视力、屈光状态、眼前节和眼底情况进行检查。结果:屈光矫正术后行人工晶体植入的9只眼中,2只眼达到了术前预测的屈光度,接近正视;3只眼达到术前预测的-5.0的屈光度,随时间的推迟,近视度数逐渐回退;4只眼未达到术前预测的屈光度,产生+5.00～+7.00的屈光度,其中2只眼行人工晶体更换术。结论:对于近视眼屈光矫正术后的白内障病人,若白内障术前预测人工晶体度数较大时,SRK公式所计算的人工晶体度数可参考并使用;如预测人工晶体度数较小（<+10.00D）时,人工晶体值仅供参考。选择最佳的人工晶体计算公式和改进角膜屈光度的测量方法是消除屈光矫正术后人工晶体度数发生错误的关键,也是有待于进一步探讨的研究课题。
Objective: To investigate the reliability of cataract surgery after cataract surgery, refractive status changes and the choice of intraocular lens power. Methods: Six patients (9 eyes) with cataract treated with RK, PRK, ALK and LASIK underwent cataract extraction and phacoemulsification combined with intraocular lens implantation. The mean corneal surface area -5.00D) intraocular lens, follow-up 3 months to 3 years of cataract preoperative and postoperative visual acuity, refractive status, anterior segment and fundus conditions were examined. Results: Of the 9 eyes implanted with IOL, the preoperative refractive power reached the preoperative refractive power and was close to the anterior face. The 3 eyes achieved a preoperatively predicted refractive power of -5.0. With the delay of time, myopia The degree of gradual regression; 4 eyes did not reach the preoperative refractive power, resulting in +5.00 ~ +7.00 diopter, of which 2 eyes underwent artificial lens replacement. CONCLUSIONS: For patients with cataract who have undergone refractive correction of myopia, the intraocular lens (IOL) calculated by the SRK formula can be used as reference if the predicted intraocular lens (IOL) is large before cataract surgery. If the IOL is predicted to be small (<+10.00 D), IOL value is for reference only. Choosing the best intraocular lens formula and measuring corneal refractive power is the key to eliminate the error of intraocular lens (IOL) after refractive surgery, and is also a research topic to be further explored.
