Filter by:A multi-disciplinary intervention will reduce inappropriate preoperative testing for cataract surgery. Despite multiple rigorous randomized controlled trials and meta-analyses showing that pre-operative testing for cataract surgery does not improve outcomes, pre-operative testing has not declined. A quality improvement initiative, which includes gaining senior leadership support, changing the culture of care, and elimination of pre-operative consultation visits for cataract surgery, to reduce inappropriate pre-operative testing. Quasi-experimental difference-in-difference analysis comparing the intervention arm (LAC+USC Medical Center) with the control arm (Harbor-UCLA Medical Center), 6 months prior and 6 months after the intervention. Generalized estimating equation models will adjust for age, gender, race/ethnicity, comorbidities and cluster by site.
To evaluate rotational stability of the investigational device implanted after cataract surgery.
Intracameral injection of 0.1% moxifloxacin solution after cataract surgery to prevent endophthalmitis
To compare the clinical sedative effect and safety using 10% chloral hydrate during ophthalmic examinations for oral vs enema group.The patients were randomly divided into two groups (oral group and enema group) using a computer random number generator with a 1:1 allocation (simple randomization, odd number for oral group and even number for enema group).
Evaluate efficacy and safety of the toric IOL implanted into aphakic eye with corneal astigmatism after cataract surgery.
In this study, the investigators provide participants≤14 years old the artificial intelligent clinic or normal clinic in the purpose of seeking out a better way to make a definite diagnosis with high efficiency and accuracy, and report a prospective, randomized controlled study aiming at comparison of artificial intelligent clinic and normal clinic for diagnosing congenital cataract.
This prospective, non-randomized controlled study aiming at comparing the prognosis of minimal invasive lens surgery and traditional cataract surgery for treating congenital cataracts after the patient receives secondary intraocular artificial lens (IOL) implantation.
Previously, we 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.
Purpose: To compare the effect of spherical aberration on optical quality in eyes with two different aspherical intraocular lenses Methods: In this prospective, randomized clinical trial 120 eyes of 60 patients underwent phacoemulsification. In patient's eyes an aberration-free aspherical IOL (Aspira-aA; Human Optics) or an aberration-correcting aspherical IOL (Tecnis ZCB00; Abott Medical Optics) were randomly implanted. Three months after surgery visual acuity, contrast sensitivity, wavefront measurements with iTrace as well as tilt and decentration measurements with Visante anterior segment OCT were performed.
Nowadays, doctors put mental health at a prior place and pay more attention to the psychological problems of ill kids' parents. In our research, we try to find a new modern and efficient psychological counseling mode to improve the mentality of parents and relieve their anxiety and depression. We divide guardians of parents into two groups .One group is given the traditional follow-up by regular phone call every month. The other is in a wechat group. A doctor send the useful information about kids care and answer questions of parents at regular time every month. The self-rating anxiety scale (SAS) and self-rating depression scale (SDS) scores of parents are marked before and after the long follow up.
