Filter by:Rigorous and regular follow-up is essential to successful management of childhood cataract, but it is often ignored by parents and especially difficult to be delivered in China, such an average-medical-resource-limited country. Health programmes that use mobile communication technologies are emerging with the aim of strengthening health systems. The investigators aimed to assess whether mobile phone short message service (SMS) for parents of cataract children involved in the Childhood Cataract Program of Ministry of Health of China (CCPMOH) improved follow-up adherence and detection rate of the timing of surgery, postoperative complications and necessary replacement of glasses.
The Congenital Muscle Disease Patient and Proxy Reported Outcome Study (CMDPROS) is a longitudinal 10 year study to identify and trend care parameters, adverse events in the congenital muscle diseases using the Congenital Muscle Disease International Registry (CMDIR) to acquire necessary data for adverse event calculations (intake survey and medical records curation). To support this study and become a participant, we ask that you register in the CMDIR. You can do this by visiting www.cmdir.org. There is no travel required. The registry includes affected individuals with congenital muscular dystrophy, congenital myopathy, and congenital myasthenic syndrome and registers through the late onset spectrum for these disease groups. The CMDIR was created to identify the global congenital muscle disease population for the purpose of raising awareness, standards of care, clinical trials and in the future a treatment or cure. Simply put, we will not be successful in finding a treatment or cure unless we know who the affected individuals are, what the diagnosis is and how the disease is affecting the individual. Registering in the CMDIR means that you will enter demographic information and complete an intake survey. We would then ask that you provide records regarding the diagnosis and treatment of CMD, including genetic testing, muscle biopsy, pulmonary function testing, sleep studies, clinic visit notes, and hospital discharge summaries. Study hypothesis: 1. To use patient and proxy reported survey answers and medical reports to build a longitudinal care and outcomes database across the congenital muscle diseases. 2. To generate congenital muscle disease subtype specific adverse event rates and correlate with key care parameters.
During cataract operations a capsulorhexis is being performed. This is done in order to enable the removal of lens material while keeping the capsule intact in order to put inside the lens capsule an artificial intra ocular lens. The capsulorhexis must be round and with regular edge and no tears. While performing a cataract surgery we use phako emulsification machine that sends an ultrasonic wave that creaks the lens nucleus and at the same time irrigates the anterior chamber of the eye and sucks the fluid and the lens material of the creaked lens. The round shape and the regularity of the capsulorhexis are a must in these surgeries since the lens capsule must stay intact and stable in order to enable the phacoemulsification and the implant of the artificial lens. Today capsulorhexis are done with a bent needle or with special forceps; the act of capsulorhexis is delicate, sometime un predicted and difficult to teach. The learning curve is relatively long and difficult. The proposed device enables a capsulorhexis which is round and has regular edges, done almost automatically and is predicted. The learning curve is short and easy. The capsulorhexis is done through the original operating wound with no need to widen it.
The aim of the study is to evaluate the safety and effectiveness of a new cartridge for the implantation of foldable intraocular lenses.
Assess prophylactic efficacy of topical non-steroidal anti-inflammatory drops in preventing macular edema. Patient undergoing uncomplicated cataract surgery will be enrolled and randomized to nepafenac, ketorolac, or placebo. Follow-up will occur at 1 month with ocular coherence tomography (OCT).
The purpose of this study is to evaluate the aqueous humor concentration of bromfenac sodium in subjects administered multiple topical ocular doses of ISV-303 or Bromday™ QD prior to routine cataract surgery.
Cataract surgical techniques have significantly changed in recent years with the widespread adoption of smaller and smaller clear corneal incisions for phacoemulsification. Microincision surgery has many advantages, including reduced surgically induced astigmatism, faster visual recovery, and reduced intra and postoperative inflammation. Curently, microcoaxial phacoemulsification is being performed through 1.8 as well as 2.2 mm incisions. However, there is still a debate as to which is the best absolute incision size for microcoaxial cataract surgery. The aim of this study is to evaluate incision stability following microcoaxial phacoemulsification performed through 1.8 and 2.2 mm systems, as well as compare intraoperative performance and postoperative outcomes following microcoaxial phacoemulsification performed through these two incision sizes.
Patients are routinely given steroid eye drops following cataract surgery. This study will compare 2 approved drops:Loteprednol Etabonate versus Prednisolone Acetate Eye drops used following cataract surgery. Patients will be randomly assigned to one drop or the other, and evaluated for inflammation and intraocular pressure as part of the comparison. The study Doctor will be masked as to which drop the patient receives to avoid bias.
The purpose of this study is to prove the efficacy and safety of the Femtosecond laser to create a clear corneal incision during cataract surgery.
