Active clinical trials for "Cataract"

The purpose of this study is to determine if an eye drop video monitoring device can accurately assess (as compared to a patient's own log or a proprietary software) the exact amount and time of eye drop delivery to a patient's eye. It is our belief that the experimental device will help patients to be more compliant by: 1) providing a viewable format so patients can see what is happening when they are applying their drops 2) providing greater accuracy to doctors regarding when and how much medication was used 3) providing greater accuracy to doctors and patients regarding how much medication was actually delivered to a patients eye.

Patients having cataract extraction in the second eye under topical anesthesia with monitored anesthesia care often report increased pain and awareness relative to the first surgery in the fellow eye, despite similar operative and anesthetic conditions. The purpose of this study is to investigate the pathogenesis of this phenomenon.

A prospective study reporting on Ex-PRESS shunt implantation alone or combined cataract and glaucoma surgery.

Eye drops must be proficiently instilled to prevent infections following cataract surgery. Proficiency is defined as placing a drop on the ocular surface without touching the applicator's tip. Researchers will investigate whether patients can proficiently administer eye drops on the first attempt on the first day after surgeries. If successful, researchers will determine how proficient they are 29 days later. If not, they will be provided with additional educational sessions and tested again 29 days later. Researchers will also determine if the proficiency of instillation correlates to whether patients experience irritation or pain after surgery. Summary Brief Summary Eye drops must be proficiently instilled to prevent infections following cataract surgery. Proficiency is defined as placing a drop on the ocular surface without touching the applicator's tip. Researchers will investigate whether patients can proficiently administer eye drops on the first attempt on the first day after surgeries. If successful, researchers will determine how proficient they are 29 days later. If not, they will be provided with additional educational sessions and tested again 29 days later. Researchers will also determine if the proficiency of instillation correlates to whether patients experience irritation or pain after surgery. Hypotheses: On postoperative day 30, there will be a higher rate of successful eye drop instillation in the group of subjects who receive the educational session compared to the baseline group subjects (subjects only tested on postoperative day 30 rather than both the first day after surgery and postoperative day 30) who will not receive it. In comparing the postoperative day 30 proficiency levels of baseline subjects and subjects who were able to proficiently instill a single eye drop on postoperative day 1, the subjects who were able to proficiently instill a single eye drop on postoperative day 1 will have a higher success rate than the baseline group. The number of subjects who are unable to correctly instill the medication on postoperative day 30 and experienced pain or irritation before or during postoperative day 30 will be higher than the number of subjects who are able to correctly instill the medication on postoperative day 30 and experienced pain or irritation before or during postoperative day 30.

The purpose of this study is to examine the efficacy of a capsular tension ring (CTR) in preventing anterior capsule shrinkage after cataract surgery in exfoliation syndrome (XFS) with no zonular weakness. The eyes with XFS undergo phacoemulsification and aspiration (PEA) with an intraocular lens (IOL) implantation. All operations are performed by a single surgeon. No eyes with either ectopia lentis or phacodonesis are included. There are three groups; CTR is not used in group A, CTR is simply implanted in group B, and CTR is implanted and closed by tying both eyelets in group C. The areas of continuous curvilinear capsulorhexis (CCC) are calculated, and both the time-course change and the comparison among the 3 groups are tested.

To analyze and compare visual results, keratometry, SIA and HOAs outcomes of biaxial microincision cataract surgery in elderly population, including diabetic and non-diabetic patients.

To evaluate the impact of a health education program on parental anxiety, the comprehension-memorization of the information and their satisfaction.

Laser-assisted cataract surgery is an innovative and growing procedure to improve the safety and results of modern cataract surgery. However, this technique faces to some obstacles: economics in the one hand due to the cost and time spent for the laser procedure before the conventional surgery, and technical in the other hand, especially due to some loss of pupil dilation during the surgery, which is highly important to ensure a perfect procedure. The present study aims at assessing a pharmacological protocol to maintain an accurate pupil dilation all along the surgery in order to improve the whole procedure.

To determine whether a decision aid increases informed decision about cataract surgery for patients with age-related cataract.

The purpose of this study is to assess the effects of diabetes mellitus (DM) on anterior chamber cytokine production and postoperative macular edema in patients undergoing femtosecond laser-assisted cataract surgery (FLACS). Patients with DM routinely undergo FLACS, yet the majority of studies evaluating intraocular inflammation following femtosecond laser treatment have excluded this patient population. Importantly, DM alters the inflammatory status of the eye, which may influence the production of inflammatory mediators following femtosecond laser treatment and the development of postoperative macular edema. The results from this study will provide insight into the risks and benefits of FLACS in patients with DM.
