5 Clinical Trials for Various Conditions
At the New England College of Optometry in Boston, MA, subjects ages 18-65 who have received or are receiving treatment for refractive error who choose to enroll in the study will be evaluated using subjective refraction and automated refraction, by way of the QuickSee Plus refractor. Subjects will then be randomized into one of two treatment plans: receive glasses from automated refraction first then subjective refraction second, and vice versa. After one week of wearing the first pair of glasses, patient preferences are assessed, and glasses are switched. After a week of wearing the second pair of glasses from the alternate measurement method, patient preferences are again assessed. Patients may then decide which pair patient like best. This is a triple blind, case-crossover clinical trial.
A high-performance smart eyeglasses system with integrated sensing, actuation, control and data collection is being developed at the University of Utah. These smart eyeglasses use tunable lenses and integrated sensor technologies to correct blurred vision caused due to a major age-related condition called presbyopia.The objective of this study is to test this smart system on patients suffering from presbyopia aged 45 and above. The researchers intend to study the effect of these smart eyeglasses by qualitatively investigating the patient's visual acuity with this smart system. The results of this study and subsequent research have the potential to lead to major lifestyle improvements and better treatment for millions of presbyopic patients that are constrained by the limitation of current corrective eyeglass technologies. There are two main sources of fairly well understood problems that lead to presbyopia and loss of the eye focusing function. The adaptive eyeglasses used in these tests do not fix any of the internal eye problems. They just compensate externally for the loss of the eye focusing function caused by presbyopia. As such, the investigators intend to evaluate our system's effectiveness in terms of the sharpness of the perceived images.
The purpose of this study is to compare developmental outcome for young children (12 to 35 months of age) with astigmatism meeting American Academy of Ophthalmology spectacle prescribing guidelines and who are prescribed and provided spectacles for either Full-Time wear (encouraged and reinforced) or Ad Lib wear (wear dependent on child acceptance).
This is a research study designed to test the utility of D-shaped bifocal lenses and PRIO Computer Lenses for persons using a computer. We hypothesize that lenses specially designed for computer use may allow more comfortable and productive work on a computer.
The purpose of this study is to assess the level of visual functioning in patients with various eye conditions while wearing different types of eyeglasses.
