View clinical trials related to Congenital Cataract.
Filter by:Approximately 30 eyes with congenital cataract who underwent primary or secondary intraocular lens implantation surgery at Zhejiang Eye Hospital from March 2018 to December 2020 were enrolled. According to the implantation method of IOL, patients were devided into the optic capture group and the endocapsular group. And through the clinical parameters of postoperative best corrected visual acuity (BCVA), intraocular pressure (IOP), IOL position and whether appear visual axis opacity to compare the outcome of the 2 IOL implantation methods.
Selecting the appropriate surgical approach for congenital cataracts presents challenging for ophthalmologists. This prospective, randomized controlled study aims to compare the prognosis of posterior continuous curvilinear capsulorhexis (PCCC) with or without anterior vitrectomy (A-Vit) in treating congenital cataracts.
To evaluate the influence of the visual acuity after congenital surgery on the retinal and visual cortex structure.
The ocular biometric parameters of the children with congenital cataract including preoperative pupil diameter, corneal diameter, axial length, anterior and posterior capsule size, iris adhesion. And then analysis whether the preoperative parameters were correlated with the implantation site of secondary implantation.
Early cataract surgery in microcornea/microphthalmia eyes is essential to prevent amblyopia and improve visual outcomes, including stereopsis. However, despite recent advances in pediatric cataract microsurgical techniques, this surgery remains challenging owing to several intraoperative difficulties attributable to the crowded anterior segment in these small, soft, and poorly developed eyes with shallow anterior chambers, and poor pupillary dilation. In this study the investigator aim to report on the changes in the anterior segment biometric characteristics after cataract extraction in eyes with microcornea/microphthalmia with congenital cataract.
Previously, the investigators have developed a surgical technique to reduce inflammatory response after congenital cataract surgery. This prospective, randomized controlled study aims to compare the prognosis of traditional cataract surgery with traditional surgery combined triamcinolone staining of the anterior vitreous in treating congenital cataracts.
Pediatric patients who have undergone surgery for congenital or infantile cataracts have a risk of developing suspected glaucoma and glaucoma, but the current evidence does not address our understanding of the incidence and associated risk factors of suspected glaucoma/glaucoma for application in clinical standard care. Therefore, this study investigated the incidence of and risk factors for suspected glaucoma/glaucoma in patients who have undergone surgery for congenital/infantile cataracts.
Previously, the investigators have developed a minimal invasive lens surgery in the purpose of reduce post-operative complications of congenital cataract. This prospective, randomized controlled study aims at comparing the prognosis of the minimal invasive lens surgery and the traditional cataract surgery for treating congenital cataracts.
To evaluate the impact of a health education program on parental anxiety, the comprehension-memorization of the information and their satisfaction.
Few descriptive studies have focused on the anatomical parameters in patients with preexisting PCDs. The characteristics of cataract morphology and anatomical parameters in these patients remained unclear, when compared with CC patients with intact posterior capsule. We conduct the current study to compare the cataract morphology and preoperative parameters, including central corneal thickness, axial length, anterior chamber depth, lens thickness, corneal diameter, keratometry，dialated pupil diameter and intraocular pressure, between CC patients with preexisting PCDs and those with intact posterior capsule, and to explore potential risk factors for preexisting PCDs.
