Filter by:AGN-190584 has gone through many clinical trials showing its safety and effectiveness in individuals from 40-55 years of age. There has been no published data on the use of this product in individuals corrected with contact lenses for distance vision. There are many other applications AGN-190584 could be used for and further studies will show the effectiveness for each.
Presbyopia is a condition in which the eye exhibits a diminished ability to focus on near objects with increasing age. This study will assess the safety and exploratory efficacy of AGN-190584 is in treating participants with pseudophakic presbyopia. AGN-190584 is approved (in the United States) for use in adults with presbyopia (including those who are pseudophakic) and this study is being conducted to better understand the safety and efficacy in the pseudophakic presbyopia population. This study is double-masked meaning that neither the participants nor the study doctors will know who will be given AGN-190584 and who will be given vehicle (does not contain treatment drug). Study doctors put the participants in 1 of the 2 groups, called treatment arms. Each group receives a different treatment. There is a 1 in 3 chance that participants will be assigned to vehicle. Approximately 150 participants aged 40-80 years with pseudophakic presbyopia will be enrolled in approximately 30 sites in the US. Participants will receive eye drops of AGN-190584 or vehicle once daily in the morning in each eye for 14 days. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study. The effect of the treatment will be evaluated by medical assessments, checking for side effects and completing questionnaires.
The primary objective of this clinical study is to assess the clinical performance of the AcrySof IQ Vivity Extended Vision IOL in a Chinese population.
Controlled, open label, prospective Post Market Clinical Follow-Up, single-center clinical study to investigate visual performance after implantation of a trifocal IOL (PhysIOL Pod L GF) in patients that underwent refractive surgery.
The objective of this clinical study is to evaluate the safety and effectiveness of subepithelial implantation of the Allotex TransForm corneal allograft (TCA) for improving near vision in presbyopic subjects.
The aim of this study is to analyze the results of PresbyLASIK performed using the wavefront-optimized LASIK for the treatment of presbyopia on low hyperopic and low myopic patients with astigmatism. Visual performance will be assessed using clinical outcome measures of the following: refraction, near, intermediate and distance visual acuity, stereoacuity and contrast sensitivity. Questionnaires will also be used to evaluate how the patient's vision is before and after surgery.
Chemotherapy drugs, used in cancer treatments, may change the timing of a vision condition known as presbyopia. Presbyopia is the inability to focus the eye on close objects, by a process called accommodation. It is caused by an increase in the stiffness of the lens of the eye that occurs naturally with aging. Currently, there are no known treatments that can be used to prevent or delay presbyopia. As a result, the risk, in later life, of having this condition is essentially 100%. The purpose of this research is to determine whether chemotherapy drugs are delaying the age at which people develop symptoms of presbyopia. We hope to establish that presbyopia can in fact be delayed with the use of drugs, which would ultimately lead to further research in this area.
