To analyze refractive changes after neodymium: yttrium-aluminum-garnet (Nd:YAG) posterior capsulotomy in pseudophakic eyes.
Patients who underwent Nd:YAG capsulotomy after cataract surgery from January 2013 to April 2022 were included in this retrospective study. Sphere, cylinder, spherical equivalent (SE), axis, and corrected distance visual acuity (CDVA) were compared pre- and postoperatively in 683 eyes of 548 patients at one month (n = 605 eyes) and one year (n = 211 eyes). Patients with both one-month and one-year follow-ups (n = 133) were also compared. Eyes were stratified into single-piece (n = 330), three-piece (n = 30), and light adjustable lenses (LALs) (n = 16). Pre- and postoperative measurements were analyzed within each group.
Cylinder was significantly decreased at one-month (difference: 0.042±0.448 D, p = 0.006) and one-year (difference: 0.101±0.455 D, p = 0.003) compared to preoperative measurements. No significant change in sphere or axis was observed at follow-up visits (p > 0.05). CDVA significantly improved at both time points (p < 0.05). No significant change in any parameters between the one-month and one-year groups was observed (p > 0.05). There was significant improvement in CDVA in the single and three-piece lens groups (p < 0.0001 and p = 0.026, respectively), with no change in the LAL group (p > 0.05).
There were no changes in sphere, axis, or spherical equivalent after Nd:YAG capsulotomy. However, cylindrical error and CDVA were significantly better after the procedure. Lens type did not impact refractive parameters postoperatively.
分析人工晶状体眼行钕：钇铝石榴石（Nd:YAG）后囊切开术后的屈光变化。
本回顾性研究纳入了2013年1月至2022年4月白内障手术后接受Nd:YAG囊切开术的患者。对548例患者的683只眼在术后1个月（n = 605只眼）和1年（n = 211只眼）时的球镜、柱镜、等效球镜（SE）、轴位和矫正远视力（CDVA）进行术前和术后比较。对有1个月和1年随访的患者（n = 133）也进行了比较。将眼睛分为单片式（n = 330）、三片式（n = 30）和可调节人工晶状体（LALs）（n = 16）。对每组内的术前和术后测量值进行分析。
与术前测量值相比，柱镜在术后1个月（差值：0.042±0.448 D，p = 0.006）和1年（差值：0.101±0.455 D，p = 0.003）时显著降低。随访时球镜或轴位未观察到显著变化（p > 0.05）。两个时间点的CDVA均显著改善（p < 0.05）。1个月组和1年组之间的任何参数均未观察到显著变化（p > 0.05）。单片式和三片式人工晶状体组的CDVA有显著改善（分别为p < 0.0001和p = 0.026），而LAL组无变化（p > 0.05）。
Nd:YAG后囊切开术后球镜、轴位或等效球镜无变化。然而，术后柱镜误差和CDVA明显改善。人工晶状体类型对术后屈光参数无影响。
