Filter by:The objective of this study is to evaluate the product performance of a new silicone hydrogel daily disposable multifocal contact lens, the Bausch + Lomb (kalifilcon A) Daily Disposable Multifocal Contact Lens, when worn by current soft contact lens wearers on a daily disposable wear basis
This was a single-blind (participant masked), interventional, prospective, direct refit, bilateral wear short-term fitting study.
Uncorrected refractive error is a leading cause of visual impairment in children and can impact vision, quality of life, and academic performance. Despite Boston Children's Hospital serving patients from a wide range of socioeconomic backgrounds, there are health disparities in access to eyeglasses as a consequence of patients' health insurance. The investigators will examine whether the use of an in-clinic app for 3-D printed glasses reduces disparities in access to eyeglasses for our patients on Medicaid. The intervention will address social determinants of health and improve pediatric health outcomes namely, how and when children having publicly funded health insurance receive eyeglasses. The short-term objectives are (1) to compare the time to receive glasses between publicly funded MassHealth eyeglasses and an in-clinic order of 3D printed glasses (2) to evaluate compliance with glasses wear in these two groups, and (3) to evaluate visual function and quality-of-life outcomes in these two groups. This prospective randomized control study will evaluate barriers to accessing eyeglasses in school-aged children. The investigators will recruit children enrolled in MassHealth and randomize them into two cohorts: (1) the control group will receive MassHealth glasses as per standard of care, through an optical shop of their choosing, or (2) the intervention group will use an app for immediately ordering glasses (paid for by the study) in clinic following their appointment. The investigators will evaluate the time needed to receive eyeglasses, compliance with glasses wear, quality of life, and visual outcomes between the cohorts at one-, three-, and six-month intervals. Through this project, the investigators will not only evaluate, quantify, and bring awareness to disparities in our patient population, but will also look toward finding a solution through the use of a novel application that addresses many of the barriers faced by patients insured through Medicaid.
The purpose of this study is to determine whether uncorrected or corrected long-sightedness (hyperopia) has an impact on reading skills, in Grade 2 or Grade 4 school-aged children from Mashonaland Central province of Zimbabwe, compared to age-, gender- and school-matched children with no refractive error (emmetropia), measured by the Happy Readers V4 reading tool over six months.
The purpose of this study is to investigate the variability of RNFL and macular thickness between myopia , hyper metropia and emmetropia
Photorefractive Keratectomy (PRK) is a commonly performed corneal refractive surgery but has significant post-operative pain. Pain medications after PRK are typically opioid-acetaminophen combinations. Alternatives to opioid medication are worth consideration. Patients will receive PRK in each eye sequentially, using the cannabinoid or codeine/acetaminophen for one eye and the other treatment for the fellow eye two weeks later.
This will be a multicenter, prospective, open label, non-randomized, single arm 12 month study, evaluating the safety and effectiveness of the TECHNOLAS TENEO 317 Model 2 (Software version "1.28 US") excimer laser when used in LASIK surgery to treat hyperopia with or without hyperopic astigmatism. Both eyes of a subject may be enrolled so long as both eyes meet all inclusion/exclusion requirements. Analysis of the primary effectiveness endpoint will be completed at refractive stability.
Hyperopia is one of the commonest refractive errors encountered in ophthalmology practice. Laser in situ keratomileusis (LASIK) has been widely used to correct hyperopia especially with the advent of femtosecond laser technology allowing larger flap creation suitable for peripheral hyperopic ablations with resultant predictable, effective, and safe refractive outcomes. However, the encountered LASIK flap complications encouraged many surgeons to assess efficiency and safety of surface ablation techniques such as photorefractive keratectomy (PRK) to correct hyperopia.
This is a multicenter study to compare the accuracy of IOL calculations in post-laser vision corrected eyes that are about to undergo or have undergone cataract surgery.
The purpose of this open controlled multicenter trial is to assess the impact of use of an amniotic membrane on post PKR recovery.
