Comparison of final visual acuity: cataract surgery with intraoperative complications versus non intraoperative complications

Abstract

A principal complicação foi ruptura de cápsula posterior. Conclusão: Após toda a análise, verificamos que os fatores que implicaram com significância estatística em menor AV final foram as complicações intraoperatórias e a idade dos pacientes. Descritores: Cristalino; Catarata; Extração de catarata; Procedimentos cirúrgicos oftalmológicos; Facoemulsificação; Acuidade visual Objective: Compare visual acuity (VA) of patients after cataract surgery with and without intraoperative complications regarding possible factors that contributed to the outcome on postoperative follow-up. Methods: Longitudinal, retrospective study that evaluated 179 medical records of patients who underwent cataract surgery under the technique Phacoemulsification (PHACO) in the Suel Abujamra Institute from february to july 2013. Patients were divided into two groups concerning presence or absence of intraoperative complications. Data were analyzed using t-test methods for two samples or (ANOVA) Analysis of Variance. Exclusion criteria were: patients with previous ocular surgery, retinopathy related to diabetes, either proliferative or severe non proliferative, other retinopathies, optic disc cup equal to or greater than 0,7x0,7, use of more than two ocular hypotensive medications, only one eye, cataract due to uveitis, trauma or congenital. Results: 37 (20.7%) patients had intraoperative complications and 142 (79.3%) had not. Average age of patients was 70.33 years. There were 49.7% surgeries of the right eye and 50.3% of the left eye. There were 29.05% diabetic patients, of which 29.73% had intraoperative complications and 28.87% had not. From the 179 patients, 77.65% reached a final VA of 20/40 or better, considering that patients with intraoperative complications reached a VA of about 59.46% and patients without intraoperative complications of about 82.40%. The main complication was posterior capsular tear. Conclusion: After entire evaluation, we realized that factors that influenced lower final VA, with statistical significance, were intraoperative complications and patient age.

Causes of Suboptimal Corrected Visual Acuity following Phacoemulsification in a Teaching University Hospital

“…The rate of capsular rupture and the visual outcome are comparable to the Kange and coworkers (8) study that was conducted to compare VA of patients after cataract surgery with and without intraoperative complications to assess the outcome on postoperative follow-up. They found that 142 (79.3%) were uneventful, while 37 (20.7%) patients had intraoperative posterior capsular rupture, compared to 23.3% in our study.…”

Factors Influencing Visual Improvement after Phacoemulsification Surgery among Malaysian Cataract Patients

“…A previous study by Konstantopoulos et al [ 26 ] reported that vitreous loss was significantly associated with poor postoperative VA [ 26 ]. In general, pre- and post-surgery VA is significantly different between patients with and without intraoperative complications [ 27 ]. Our study had the same findings as the previous studies: intraoperative complications related to the visual outcome after surgery.…”
