416 Clinical Trials for Various Conditions
Contact lens (CL) discomfort is a complex phenomenon that has been defined by the Tear Film and Ocular Surface Society (TFOS) in their seminal report on CL discomfort as a condition that results in "episodic or persistent adverse ocular sensation related to lens wear, either with or without visual disturbance resulting from reduced compatibility between the CL and the environment, which can lead to decreased wearing time and discontinuation of CL wear."
Determine the likelihood of successfully refitting a satisfied AOA CL wearers into P7A CLs
Many people suffer from migraine headaches, some more so than others and a common trigger/complaint is light sensitivity, or photophobia1. Some will go to great lengths to avoid light: a dark room with sunglasses on and blankets over the windows, often missing work/school/social activities, etc. Several ocular conditions are accompanied by photophobia, ranging from mild to debilitating.

This open-label study is of adults with astigmatism who have never worn contact lenses. Subjects will be fit into a one week planned-replacement contact lenses and will wear lenses for approximately 3 weeks. Subjects will return for vision and lens fit assessments and will complete surveys about their wear experience.
This is a prospective, multi-site, 4-visit, bilateral, dispensing, randomized, controlled, double-masked, 2x2 crossover study to evaluate subjective comfort, overall opinion and end of day comfort following wear of two different contact lenses.
The goal of this clinical trial is to learn if a new contact lens device can record patterns in eye pressure for 24 hours in adults with glaucoma and in healthy participants. The main questions it aims to answer are: * Is the contact lens device able to detect patterns in eye pressure that happens naturally between nighttime and daytime? * Are the contact lens recording patterns similar when repeated one week later? * What eye problems do participants have when wearing contact lens for up to 24 hours? Researchers will compare if the recordings detected by the contact lens over 24 hours are similar to the patterns measured by an eye pressure measuring instrument used in a doctor's office. Participants will * Wear contact lens in one eye for up to 24 hours * Take recordings in that eye with smartphone camera every 15 minutes when awake * For those participants who are able to stay overnight at a hotel for the trial, researchers will measure the eye pressure in the other eye every 1 to 2 hours when awake with an eye pressure measuring instrument.

This open-label study is of current Acuvue® Oasys® wearers (2 - week replacement, reusable lenses) who are satisfied with their current lenses. Subjects will be refit into one week reusable contact lenses and will wear lenses for approximately 2 weeks. Subjects will return for vision and lens fit assessments and will complete surveys about their wear experience.
This will be an open-label, 3-visit, single-arm, dispensing clinical trial to evaluate visual acuity.
Purpose: Numerous studies have proven that emmetropization in young animals including humans is regulated by visual input. It has long been hypothesized that peripheral myopic defocus may act as a stop signal to reduce myopia progression and axial elongation. As such, multifocal soft contact lenses (MFCLs) have been utilized for myopia control in school-aged children, with variable efficacies. One potential explanation is that the actual peripheral myopic defocus an eye experiences during MFCL wear may not be identical to the Add power and not sufficient to reduce myopia progression. Our study investigated and compared the peripheral power profiles of myopic eyes when they were uncorrected and wore single vision contact lenses (SVCLs) and MFCLs of different Add powers. Methods: Subjects with -1.00 D to -10.00 D of myopia (SE, determined with manifest refraction) were custom fit with both single vision (SV) and MFCLs (+2.00 and +4.00 D Add; provided by Specialeyes) in both eyes. These Specialeyes MFCLs had an aspheric design with a standard total optical zone of 8.0mm. Cycloplegic central autorefraction was conducted with both Grand Seiko WAM-5500 open-field auto-refractor (Grand Seiko Co Ltd) and OPD OPD-Scan III Wavefront Aberrometer (Marco) on the subjects in the following conditions: (1) no CLs, (2) SVCLs, (3) MFCLs (+2.00D Add), and (4) MFCLs (+4.00D Add). Relative peripheral power profiles were measured using the OPD under the same 4 conditions after cycloplegia. Data in the right eye was used for analysis.
This is a multi-site, bilateral, dispensing, non-randomized, uncontrolled, unmasked, single arm study to evaluate visual acuity in neophytes.
To evaluate the performance of Total 30® (lehfilcon A) contact lenses in patients using digital devices for greater than 8 hours per day 5 days per week based on subjective reported data.
To compare the efficacy of XDEMVY ophthalmic drop to its vehicle control for the treatment of Demodex blepharitis and its impact on the soft contact lens wearing experience.
Miebo (Perfluorohexyloctane) is a novel, non-aqueous, single entity, preservative free, ophthalmic drop. This drop was recently approved by the Food and Drug Administration (FDA) for the treatment of Meibomian Gland Disease (MGD). All published data on Miebo has been done in non-contact lens wearers. As contact lens dropout rates seem to be an ongoing problem for practitioners, we are performing this study utilizing this novel new drug with contact lens patients to determine if the drops assist comfort in typical soft contact lens wearing patients. If the study determines that Miebo assists in the overall comfort of contact lens patients this could be a possible way to help keep patients in their contact lenses longer.
A single site, open label protocol will be used to evaluate the safety and quality of vision of a novel soft contact lens. Habitual contact lens wearers will be asked to come to the study site for one visit. Ocular health assessments and visual acuity will be completed with both the study lens and without.

Approximately 30 soft toric contact lens adapted subjects will be enrolled in this feasibility, bilateral, randomized, double-masked (subject and investigator), repeated measures insertion study. All subjects will be seen for a Screening/Dispensing Visit at which informed consent will be obtained and eligibility will be assessed. If subjects satisfy all eligibility criteria, subjects will be dispensed study lenses according to unique randomization tables that will be provided to each Investigator. If study eligibility is met, subjects will have lenses inserted in random, successive order. Subjects will be receiving each of the study lens types once, in a randomized order. The subject will wear each of the study contact lenses for approximately 10 minutes.
