<b><i>Background:</i></b> To investigate the effects of 0.05% povidone-iodine (PI) irrigation on the ocular surface structure and bacterial survival rate in patients with cataract. <b><i>Methods:</i></b> Ninety eyes of 90 patients with cataract were included. Before surgery, the operative field was irrigated with 0.05% PI and divided into 30-s, 1-, and 2-min groups. Anterior chamber fluid was cultured bacteriologically. Tear film breakup time (BUT), corneal fluorescein staining (CFS), lacrimal river height (LRH), and Schirmer test I (STI) were conducted to assess ocular surface. <b><i>Results:</i></b> In all groups, the patients had significantly shorter postoperative BUT at 1 day, 3 days, and 1 week postoperatively than preoperatively. In addition, there was still lower BUT at 1 month postoperatively in the 1- and 2-min groups. STI and LRH were all decreased postoperatively at different time points (1 day, 3 days, 1 week), while CFS was increased. With the extension of time preoperatively (1 and 3 months), the ocular surface indicators returned to the preoperative level. The bacterial cultures after eye irrigating were negative in all groups. <b><i>Conclusion:</i></b> 0.05% PI irrigating the conjunctival sac for 30 s can achieve a low bacterial contamination rate. Importantly, it reduced the damage of ocular surface, which is beneficial to the recovery of ocular surface function.
BackgroundThis study sought to report the outcomes of a combined cataract extraction, intraocular lens (IOL) insertion and micro-incision vitrectomy (MIVS) procedure for the treatment of Behcet uveitis.MethodsThis investigation involved the retrospective evaluation of a case series of patients with Behcet uveitis who underwent cataract extraction, IOL insertion and MIVS in a single surgical session at the same institution between January 2013 and November 2016. Outcome measures included visual acuity, inflammatory reaction, systemic anti-inflammatory medications, intraocular pressure (IOP) and complications.ResultsSeven eyes of seven patients with a mean age of 39.00 ± 5.54 years (range, 32 to 48 years) and a mean follow-up duration of 13.57 ± 5.83 months (range, 6 to 24 months) were studied; five patients with a history of well-controlled uveitis were included. All patients underwent cataract extraction and IOL implantation combined with MIVS. All patients received postoperative steroids, which were slowly tapered during the weeks after surgery. There were no significant complications related to the surgery. Overall, best-corrected visual acuity (BCVA) was improved from log MAR (logarithm of the minimum angle of resolution) 1.67 ± 0.67 preoperatively to log MAR 0.74 ± 0.35 postoperatively; this improvement was statistically significant (p < 0.05). All eyes were deemed quiet at follow-up, and no patients required the escalation of therapy for long-term uveitis control.ConclusionsThis retrospective series indicates that a procedure that combines phacoemulsification, IOL implantation and MIVS is a feasible technique for the removal of cataracts and pathologic vitreous in eyes with Behcet uveitis. This approach can restore vision without obvious complications.
Strabismus is a common ophthalmic disease in the process of child body development, in which the two eyes cannot gaze at the target at the same time, and the incidence of this disease of children is higher. In children with esotropia, exotropia, and up and down strabismus and other typical symptoms, the cause is genetic, innerve, and refractive and regulated, and not receiving timely treatment may lead to stereo vision and diplopia and other phenomena, affecting their learning and life. Surgical treatment is the main treatment for strabismus at present. Traditional orthodontic surgery is performed by doctors under the naked eye, often due to improper operation or suture error and other factors, resulting in more postoperative complications, such as more tissue damage, conjunctival congestion, and muscle suture reaction, which seriously affect the clinical effect of surgical treatment. In recent years, with the continuous development of microsurgical technology, the correction of strabismus under a microscope has been widely carried out in clinic. The operation under the microscope makes the operation more delicate and accurate, overcomes the defects of traditional surgery, and highlights the advantages of minimally invasive surgery. The purpose of this study was to investigate the effect of microsurgical techniques in the treatment of strabismus in children and to analyze the factors influencing the outcome. The results showed that microsurgical strabismus correction in the treatment of strabismus children has short operation time, less intraoperative blood loss, short hospital stay, high efficiency, and less complications, which is worthy of popularization. Age, preoperative strabismus angle, refractive error, distance stereopsis injury, near stereoscopic injury, and duration of disease were all independent influencing factors of postoperative efficacy.
