Abstract

Objectives: To assess the influence of technical parameters (such as phaco time and ultrasound energy) and patient`s characteristics (associated diseases, endothelial cell density (CD), intra-ocular pressure (IOP)) on visual acuity outcomes in individuals undergoing phacoemulsification surgery with intraocular lens implantation.

Methodology: This cross-sectional, retrospective study involved 122 eyes divided into 4 groups using the LOCS III system classification: Grade 1 (25 eyes), Grade 2 (21 eyes), Grade 3 (30 eyes) and Grade 4 (46 eyes). Specular microscopy was performed pre- and postoperatively, while the ultrasound energy consumption and the effective phaco time were observed intraoperatively. Results: A progressive decrease of cell density (CD) was observed in all groups at end of the 1st week postoperatively, with a mean endothelial cell loss of about 700 cell/mm2. The postoperative intraocular pressure (IOP) dropped significantly in Grade 4 cataract group from a mean value of 21.3 +- 10.06 to 17.43 +- 3.81 mmHg, accompanied by higher ultrasound energy consumption. A progressive improvement of visual acuity was observed, from the 1st day postsurgical visit to the 1st week follow-up evaluation in all the groups. Visual acuity improvement was maintained significant after 1st week only when comparing groups 1 and 4. The multiple regression analysis identified cataracts Grade 3 and 4 along with the preoperative visual acuity as strong predictors for the final visual acuity outcomes, while gender, age, IOL type, comorbidities, phaco time (EPT), ultrasound energy (U/S), preoperative intraocular pressure and cell density were not independently associated with visual acuity outcomes.

Conclusion: Our results indicated that 95.9% of the patients evaluated 1 day postoperative had visual acuity better than 6/18, while 4.1% had borderline visual acuity in the range of 6/18-6/60, being in line with the World Health Organization (WHO) standards for cataract surgery outcomes.

技术参数和患者特征对白内障超声乳化手术主要结果的影响：来自三级医疗中心的结果。

目的：探讨超声时间、超声能量等技术参数和患者特征（相关疾病、内皮细胞密度、眼内压）对超声乳化术合并人工晶状体植入术患者视力结果的影响。方法：本研究采用横断面、回顾性研究，纳入122只眼，采用LOCS III系统分为4组：1级（25只眼）、2级（21只眼）、3级（30只眼）和4级（46只眼）。术前、术后行镜下观察，术中观察超声能量消耗和有效超声时间。结果：在术后第1周结束时，所有组的细胞密度（CD）逐渐下降，平均内皮细胞损失约为700细胞/mm2。4级白内障组术后眼内压（IOP）由平均值21.3 +- 10.06明显下降至17.43 +- 3.81 mmHg，超声能量消耗增高。术后第1天至随访第1周，两组患者的视力均有逐渐改善。仅第1组和第4组比较，第1周后视力改善保持显著性。多元回归分析发现，3级和4级白内障以及术前视力是最终视力结果的重要预测因素，而性别、年龄、人工晶状体类型、合并症、超声时间（EPT）、超声能量（U/S）、术前眼压和细胞密度与视力结果没有独立的相关性。结论：95.9%的患者术后1天视力优于6/18,4.1%的患者视力介于6/18-6/60之间，符合世界卫生组织（WHO）对白内障手术结果的标准。

期刊介绍： Chirurgia is a bimonthly journal. In Chirurgia, original papers in the area of general surgery which neither appeared, nor were sent for publication in other periodicals, can be published. You can send original articles, new surgical techniques, or comprehensive general reports on surgical topics, clinical case presentations and, depending on publication space, - reviews of some articles of general interest to surgeons from other publications. Chirurgia is also a place for sharing information about the activity of various branches of the Romanian Society of Surgery, information on Congresses and Symposiums organized by the Romanian Society of Surgery and participation notes in other scientific meetings. Letters to the editor: Letters commenting on papers published in Chirurgia are welcomed. They should contain substantive ideas and commentaries supported by appropriate data, and should not exceed 2 pages. Please submit these letters to the editor through our online system.
