We present the case of a 36-year old Curschmann-Steinert myotonic dystrophy patient with posterior subcapsular cataract that we treated with unilateral implantation of an extended depth of focus intraocular lens to address his wish for spectacle independence at far and intermediate distance.
The patient underwent phacoemulsification with subsequent implantation of the AcrySof IQ Vivity IOL (Alcon, Fort Worth, TX, USA) in his left eye. Uncorrected distance visual acuity (UDVA) on the left eye increased from +0.40 logMAR preoperatively to -0.12 logMAR at 3 months postoperatively. At the three months follow-up distance corrected intermediate visual acuity (DCIVA) at 80 cm distance was -0.08 logMAR and DCIVA at 66 cm distance was 0.14 logMAR for the left eye. The defocus curve showed a functional defocus of 2.0 diopters at 0.2 logMAR or better, corresponding to the extended depth of focus. Dysphotopsia evaluation with a Halo & Glare simulator (Eyeland-Design Network GmbH, Vreden, Germany) revealed a very low level of photic phenomena.
Unilateral implantation of a new generation, non-diffractive extended depth of focus IOL was well tolerated and provided good functional results for far and intermediate distances. The patient reported a very low level of photic phenomena.
我们报告一例36岁的Curschmann-Steinert型强直性肌营养不良患者，其患有后囊下白内障，我们为其单眼植入了一款扩展焦深人工晶状体，以满足他在远距和中距摆脱眼镜的愿望。
患者接受了超声乳化手术，随后在其左眼植入了爱尔康公司（美国德克萨斯州沃思堡）的AcrySof IQ Vivity人工晶状体。左眼未矫正远视力（UDVA）从术前的+0.40 logMAR提高到术后3个月时的-0.12 logMAR。在3个月的随访中，左眼在80 cm距离处的距离矫正中视力（DCIVA）为-0.08 logMAR，在66 cm距离处的DCIVA为0.14 logMAR。散焦曲线显示在0.2 logMAR或更好时功能散焦为2.0屈光度，这与扩展焦深相对应。使用光晕与眩光模拟器（德国弗雷登Eyeland-Design Network GmbH公司）进行的眩光评估显示，光现象水平非常低。
新一代非衍射扩展焦深人工晶状体的单眼植入耐受性良好，在远距和中距均提供了良好的功能结果。患者报告光现象水平非常低。
