To analyze clinical outcomes of cataract surgery with implantation of a toric intraocular lens (IOL) and to evaluate the effect of capsular tension ring (CTR) presence or absence on the rotational stability of implanted IOLs and postoperative refraction.
This cohort study included 64 eyes of 41 patients who underwent uneventful cataract surgery with implantation of a toric IOL (enVista toric MX60T; Bausch & Lomb, Rochester, NY) to correct preoperative corneal astigmatism. In 30 eyes, a CTR (11 SR model; Videris s.r.o., Prague, Czech Republic) was co-implanted. Analyzed parameters were refraction, visual acuity, and misalignment of toric lenses.
The mean patient age was 67 years (range: 42 to 89 years) and the mean follow-up period was 5 months. Mean manifest astigmatism improved from -1.53 ± 1.15 diopters (D) preoperatively to -0.40 ± 0.61 D postoperatively (P < .001). Postoperative uncorrected distance visual acuity was 0.10 ± 0.13 logMAR (20/25 Snellen). Mean absolute IOL misalignment was 3.70° with CTR and 3.85° without CTR (P = .683). In eyes with an axial length of 24 mm or greater, IOL axis matched the planned axis in 90.5% of eyes with CTR and 81.8% of eyes without CTR (P = .964). Four eyes (6.25%) needed additional surgical IOL rotation.
In eyes after cataract surgery with implantation of a toric IOL, there were no significant differences in the rotational stability of the lens with respect to the presence or absence of CTR. In eyes with an axial length of 24 mm or greater, better IOL alignment was observed in the group with CTR. [J Refract Surg. 2020;36(3):186-192.].
分析白内障超声乳化术后植入散光矫正型人工晶状体（IOL）的临床效果，评估囊袋张力环（CTR）的存在与否对植入 IOL 旋转稳定性和术后屈光的影响。
本队列研究纳入了 41 例（64 只眼）白内障患者，这些患者均接受了白内障超声乳化术联合散光矫正型 IOL（EnVista toric MX60T；Bausch & Lomb，罗彻斯特，纽约）植入术，以矫正术前角膜散光。其中 30 只眼同时植入了 CTR（11SR 型号；Videris s.r.o.，布拉格，捷克共和国）。分析参数包括屈光度、视力和散光镜片的偏位。
患者平均年龄 67 岁（42~89 岁），平均随访时间为 5 个月。平均角膜散光从术前的-1.53±1.15 屈光度（D）改善至术后的-0.40±0.61 D（P<0.001）。术后未矫正远视力为 0.10±0.13 logMAR（20/25 Snellen）。有 CTR 时 IOL 平均绝对偏位为 3.70°，无 CTR 时为 3.85°（P=0.683）。轴向长度为 24 mm 或更长的眼，有 CTR 的眼 90.5%的 IOL 轴与计划轴相匹配，无 CTR 的眼 81.8%的 IOL 轴与计划轴相匹配（P=0.964）。4 只眼（6.25%）需要再次手术调整 IOL 旋转。
白内障超声乳化术后植入散光矫正型 IOL 时，CTR 的存在与否对镜片的旋转稳定性没有显著影响。轴向长度为 24 mm 或更长的眼，有 CTR 的眼 IOL 位置更好。[J Refract Surg. 2020;36(3):186-192.]。
