To compare residual refractive error and complication rates between eyes undergoing a manual capsulotomy and those receiving a precision pulse capsulotomy using an automated device.
This study was a non-interventional two-arm retrospective chart review of clinical results after bilateral cataract surgery or refractive lens exchange (RLE) surgery with a monofocal toric intraocular lens (IOL) or a trifocal IOL where a manual capsulorhexis (Manual) or automated precision pulse capsulotomy (PPC) was performed.
Exams from 243 eyes (122 PPC, 121 Manual) from 124 patients were reviewed; about 75% of which had a trifocal IOL implanted. There was no statistically significant difference in the MRSE with either IOL type, or overall. The overall percentage of eyes with residual refractive cylinder ≤ 0.50 D was significantly higher in the PPC group (89% vs. 79% in the manual group, p = 0.03), primarily driven by results with the toric IOL. Best corrected distance visual acuity was not statistically significantly different by group. Capsulotomy-related complications were lower in the PPC group relative to the manual group (4.1% vs. 6.6%), but this result was not statistically significant (p = 0.38).
Significantly more eyes had refractive cylinder ≤0.50 D in the PPC group. For all other measures, the automated PPC device produced clinical results equivalent to those achieved with a manual capsulorhexis.
比较接受手动撕囊术的眼睛与使用自动化设备进行精准脉冲撕囊术的眼睛之间的残余屈光不正和并发症发生率。
本研究是一项非干预性双臂回顾性图表审查,涉及双侧白内障手术或屈光性晶状体置换(RLE)手术,植入单焦点散光人工晶状体(IOL)或三焦点IOL,并进行了手动撕囊术(手动组)或自动化精准脉冲撕囊术(PPC组)后的临床结果。
回顾了124例患者的243只眼睛(122只PPC组,121只手动组)的检查结果;其中约75%植入了三焦点IOL。两种IOL类型或总体上,平均残余球镜等效屈光度(MRSE)均无统计学显著差异。PPC组残余屈光柱镜≤0.50 D的眼睛总体百分比显著更高(89%对手动组的79%,p = 0.03),主要由散光IOL的结果驱动。两组的最佳矫正远视力无统计学显著差异。PPC组与撕囊术相关的并发症低于手动组(4.1%对6.6%),但该结果无统计学显著性(p = 0.38)。
PPC组中屈光柱镜≤0.50 D的眼睛明显更多。对于所有其他指标,自动化PPC设备产生的临床结果与手动撕囊术相当。
