To evaluate clinical outcomes and visual quality 12 months after small incision lenticule extraction (SMILE) for correction of myopia with or without astigmatism in patients during the incipient phase of presbyopia.
Peking University Third Hospital, Beijing, China.
Retrospective observation study.
Patients who had SMILE for myopia and myopic astigmatism with binocular plano target refraction and aged between 39 and 45 years were included. Subjective refraction; distance, intermediate, and near visual acuities; defocus curve; anterior corneal surface aberrations and the Strehl ratio; accommodation function, and a subjective questionnaire assessing visual quality in real-life situations were evaluated 12 months postoperatively.
Clinical data of 29 cases were analyzed. The average patient age was 40.10 ± 0.94 years. The mean preoperative manifest refraction was - 4.73 ± 1.11 D (range: - 2.13 to - 6.13 D) of spherical equivalent in right eyes. At the 12-month follow-up, binocular uncorrected distance visual acuity and uncorrected intermediate visual acuity ≥ 20/20 were achieved in all patients, and 96.6% (28/29) of patients achieved uncorrected near visual acuity ≥ 20/25. SMILE induced a statistically significant increase in spherical aberration, coma, and total higher-order aberrations (P < 0.001). For accommodative function, only the negative relative accommodation improved significantly after surgery (P < 0.001). The questionnaire demonstrated high patient satisfaction with near vision, and no one reported having severe visual disturbance.
SMILE appeared to be safe and effective in improving distance vision in patients during the incipient phase of presbyopia, and a satisfactory amount of near vision was maintained in this group of subjects.
评估在老视初期患者中，采用小切口透镜切除术（SMILE）矫正近视合并或不合并散光后12个月的临床效果和视觉质量。

回顾性观察研究。
纳入年龄在39至45岁之间、因近视和近视散光接受SMILE且双眼平光目标屈光的患者。术后12个月评估主观验光、远、中、近视力、散焦曲线、角膜前表面像差和斯特列尔比、调节功能，以及一份评估现实生活中视觉质量的主观问卷。
分析了29例患者的临床数据。患者平均年龄为40.10±0.94岁。右眼术前平均等效球镜度为-4.73±1.11D（范围：-2.13至-6.13D）。在12个月的随访中，所有患者的双眼未矫正远视力和未矫正中视力均≥20/20，96.6%（28/29）的患者未矫正近视力≥20/25。SMILE导致球差、彗差和总高阶像差有统计学意义的增加（P<0.001）。对于调节功能，术后仅负相对调节显著改善（P<0.001）。问卷显示患者对近视力满意度高，无人报告有严重视觉干扰。
SMILE在改善老视初期患者的远视力方面似乎是安全有效的，并且该组患者保持了令人满意的近视力。
