Abstract：
BACKGROUND: Cataracts pose a significant clinical burden due to their complex pathogenesis. In recent years, an increase in cataracts coexisting with myopia has heightened the incidence of retinopathy and posterior vitreous detachment. Additionally, symptoms of ocular axis elongation, lens nucleus hardening, and vitreous liquefaction have become more prevalent. While conventional extracapsular cataract extraction is commonly employed, it often yields suboptimal visual outcomes. Subsequent advancements in cataract phacoemulsification and lens implantation surgeries have gained widespread acceptance for their ability to improve refraction and significantly improve uncorrected visual acuity.
OBJECTIVE: To investigate the effect of capsular treatment after phacoemulsification lens implantation in myopic patients with cataract.
METHODS: We selected 110 patients (with 134 eyes) with myopia and cataracts treated. These patients were categorized into two groups: an observation group (57 patients with 70 eyes) and a control group (53 patients with 64 eyes). The control group underwent cataract phacoemulsification and lens implantation, while the observation group received a refined capsular treatment based on the control group\'s procedure. We assessed the differences in visual acuity and quality between the two groups before and after surgery.
RESULTS: At six months post-operation, the observation group exhibited significantly improved far vision, intermediate vision, near vision, lower objective scattering index, higher Modulation transfer function cut-off frequency, and overall vision metrics at different contrast levels (100%, 20% and 9%) compared to the control group (P < 0.05). The total score of the National Eye Institute Visual Function Questionnaire in the observation group at 6 months after operation was significantly higher than that in the control group (P < 0.05). No significant difference in the incidence of adverse reactions was observed between the observation group and control group (P > 0.05).
CONCLUSIONS: Capsular treatment demonstrates efficacy in improving visual acuity and quality after phacoemulsification lens implantation in myopic patients with cataracts, warranting its clinical application.

摘要：
背景：白内障由于其复杂的发病机制而造成了巨大的临床负担。近年来,白内障与近视并存的增加增加了视网膜病变和玻璃体后脱离的发生率。此外,眼轴伸长的症状，晶状体核硬化,玻璃体液化变得更加普遍。虽然通常采用常规的囊外白内障摘除术，它通常会产生次优的视觉效果。白内障超声乳化术和晶状体植入手术的后续进展因其改善屈光和显着改善未矫正视力的能力而获得了广泛接受。
目的：探讨近视合并白内障患者行超声乳化晶状体植入术后囊内治疗的效果。
方法：我们选择了110例近视和白内障患者（134只眼）。将这些患者分为两组：观察组（57例，70只眼）和对照组（53例，64只眼）。对照组行白内障超声乳化和晶状体植入术,观察组在对照组的基础上进行精细包膜治疗。我们评估了两组手术前后视力和质量的差异。
结果：手术后六个月，观察组远视力明显改善,中间视力,近视力,较低的目标散射指数，更高的调制传递函数截止频率，和不同对比度水平下的整体视觉指标(100%，20%和9%)与对照组相比(P<0.05)。观察组术后6个月美国国家眼科研究所视功能问卷总分明显高于对照组(P<0.05)。观察组不良反应发生率与对照组比较差异无统计学意义(P>0.05)。
结论：胶囊治疗对近视白内障患者超声乳化晶状体植入术后视力和质量有改善作用。保证其临床应用。
