A case of hyperopic drift after cataract surgery in a patient with previous laser in situ keratomileusis

该文报道了一例40岁女性患者,因“双眼渐进性视物模糊3个月”就诊。患者既往于2005年因高度近视行双眼准分子激光原位角膜磨镶术(LASIK)。最佳矫正视力OD:0.2(–11.00 DS/–1.25 DC×170°),OS:0.7(–4.00 DS/–0.75 DC×25°)。双眼角膜透明,前房中深,晶状体混浊,豹纹状眼底伴后巩膜葡萄肿。诊断为双眼并发性白内障,并行右眼白内障超声乳化联合人工晶状体(IOL)植入术,术中植入+14.0 D IOL一枚,目标屈光度为–0.5 D。术后1周裸眼视力0.3,验光结果示右眼屈光度+2.75 DS,最佳矫正视力0.7。术后2周行右眼IOL置换术,由+14.0 D置换为+17.0 D。右眼术后1周裸眼视力0.8,验光结果示右眼屈光度–0.75 DC×15°。

It is reported in this article that a 40-year-old female patient presented with"progressive blurred vision of both eyes for 3 months".The patient underwent bilateral laser in situ keratomileusis(LASIK)because of high myopia in 2005.It was recorded that her best corrected visual acuity was 0.2(–11.00 DS/–1.25 DC×170°)in the right eye and 0.7(–4.00 DS/–0.75 DC×25°)in the left,and clear cornea,normal anterior chamber,cloudy lens,tessellated fundus with posterior staphyloma in both eyes.The patient was diagnosed with bilateral complicated cataract.Phacoemulsification combined with intraocular lens(IOL,+14.0 diopter(D))implantation was performed on the right eye,with the target–0.5D refractive diopter.One week after surgery,it was recorded that the uncorrected visual acuity of the right eye was 0.3,and the best corrected visual acuity was 0.7(+2.75 DS).IOL replacement of the right eye was performed two weeks after surgery,the+14.0 D IOL was replaced by+17.0 D IOL.One week after surgery,the uncorrected visual acuity of the right eye was 0.8(–0.75 DC×15°).
