To evaluate the effect of phacoemulsification surgery performed with the nondominant left hand on the corneal endothelium.
The study included 160 patients who were followed up for at least six months after uneventful cataract surgery. Seventy-seven patients who underwent nondominant left-handed phacoemulsification were evaluated as Group 1 and 83 patients who underwent dominant right-handed phacoemulsification were evaluated as Group 2. In all the patients, preoperative axial length (AL), aqueous depth (AD), anterior chamber depth (ACD), and lens thickness (LT) were evaluated. All phacoemulsification procedures were undertaken with the same device by two surgeons using the same technique, and the intraoperative cumulative dissipated energy (CDE) value, effective phacoemulsification time, and total operative time were recorded. Corneal endothelial cell density (ECD), coefficient of variation (CV) percentage, hexagonal cell percentage (HCP), and central corneal thickness (CCT) measurements were evaluated by specular microscopy preoperatively and at the postoperative first and sixth months.
The two groups had a similar age and gender distribution and did not significantly differ in terms of the preoperative AL, AD, ACD, LT, intraoperative CDE, effective phacoemulsification time, and total operative time with similar age and gender distribution (p > 0.05 for all). The preoperative and postoperative first- and sixth-month specular microscopy measurements of ECD, CV, HCP, and CCT were also similar in the groups (p > 0.05 for all).
In this study, it was observed that nondominant left-handed phacoemulsification resulted in similar changes in endothelial cell count and morphology to those obtained from dominant-handed phacoemulsification.
评估使用非优势左手进行超声乳化手术对角膜内皮的影响。
该研究纳入了160例患者，这些患者在白内障手术顺利完成后至少随访了6个月。77例行非优势左手超声乳化手术的患者被评估为第1组，83例行优势右手超声乳化手术的患者被评估为第2组。对所有患者术前评估眼轴长度（AL）、房水深度（AD）、前房深度（ACD）和晶状体厚度（LT）。所有超声乳化手术均由两名外科医生使用同一设备、同一技术进行，记录术中累积耗散能量（CDE）值、有效超声乳化时间和总手术时间。术前以及术后第1个月和第6个月通过角膜内皮镜检查评估角膜内皮细胞密度（ECD）、变异系数（CV）百分比、六角形细胞百分比（HCP）和中央角膜厚度（CCT）。
两组年龄和性别分布相似，在术前AL、AD、ACD、LT、术中CDE、有效超声乳化时间和总手术时间方面无显著差异，年龄和性别分布相似（所有p>0.05）。两组术前以及术后第1个月和第6个月ECD、CV、HCP和CCT的角膜内皮镜检查测量结果也相似（所有p>0.05）。
在本研究中，观察到非优势左手超声乳化导致的内皮细胞数量和形态变化与优势右手超声乳化相似。
