Active clinical trials for "Cataract"

A cataract is a clouding of the lens that occurs naturally with age. Cataract surgery involves removal of the cloudy lens and replacement with an artificial one. A special laser (femtosecond laser) is now being used to help make cataract surgery safer and more accurate . The femtosecond laser can also be used to correct astigmatism, an irregular curvature of the cornea, at the time of cataract surgery through a procedure called astigmatic keratotomy (AK). This study is gathering information about the specific laser settings that are used to perform astigmatic keratotomies (AK) during cataract surgery. This information will be used to improve the outcomes of patients that receive cataract surgery with astigmatic keratotomies in the future.

The purpose of this research study is to evaluate the clinical outcomes of current phacoemulsification approaches to cataract extraction involving high-frequency thermogenic energy versus the use of the MICOR System device using low-energy segment removal with a micro-interventional irrigation/aspiration port to evacuate the lens in subjects undergoing routine cataract surgery.

To compare the performance of an interactive chatbot versus senior ophthalmologists for enhancing informed decisions made by cataract patients. The chatbot was built based on large language models, and could generate medical expert-level responses.

This is multicenter, prospective, comparative and randomized study focusing on the evolution of the quality of Life and Uncorrected Binocular Visual Acuity (UBVA) evaluation at 3 months after cataract surgery in patients who underwent 4 different types of intraocular lens Implant (IOL) combinations.

Most patients treated for cataract surgery benefit from a short outpatient course with topical local anesthesia. Having to undergo surgery, especially on the eye, without being asleep, can be stressful. Sometimes waiting in a waiting room with other patients can increase this stress. Patient anxiety may increase blood pressure potentially leading to the prescription of nicardipine to allow surgery to be performed. The patient's anxiety also increases the surgeon's stress, which can alter the conditions for performing the intervention and increase the risk of intraoperative complications. Besides the administration of anxiolytics, nurses have few options for patients with anxiety. However, the treatment response time is not always appropriate and the patient's cooperation during the procedure can sometimes be impaired. The effect of music on preoperative anxiety has been evaluated in several studies and has shown a significant decrease in anxiety before surgery. MusicCare® is a "digital treatment" based on the principles of hypnoanalgesia which has been tested in the management of patients with various pathologies (depression, Alzheimer's disease, chronic pain, etc.) and has shown relative effectiveness. the absence of intervention on the pain and anxiety of patients. In the context of cataract surgery with topical local anesthesia, we would like to assess the contribution of offering the MusicCare® listening device on patients' anxiety about absence

To evaluate the safety and ocular efficacy of Dextenza in combination with an intracameral antibiotic and NSAID in controlling post-operative ocular pain and inflammation compared to standard of care topical therapy in patients undergoing bilateral cataract surgery.

The purpose of this research study is to evaluate the efficacy, patient preference, and utility of a novel eye shield that utilizes a different adhesive mechanism in comparison to the current standard of care. The aims are to see if this product could be incorporated into postoperative care in the future to improve patient satisfaction and compliance. The study will involve 20 patients during the postoperative timeframe after cataract extraction and intraocular lens placement (CEIOL). These patients will be chosen from the clinic of Dr. Marc Toeteberg who will plan to have both eye surgeries done within 3 months of each other. These patients will be randomized to either control or intervention group. Intervention group will receive our novel eye shield prototype, while control group will receive an Alcon plastic eye shield. Both groups will receive the eye shields after surgery and will be sent home with these eye shields with normal postoperative care directions. Patient will be directed to wear eye shields for 24 hours then at night for first 2 weeks after surgery, while adhering to postoperative eye drops regimen. After successfully healing and passing the postoperative timeframe for the first eye we will proceed to the second arm of the study. Approximately 1-2 months after healing from the first surgery, patient will be scheduled for cataract surgery on the other eye, as is standard of care. After surgery on the second eye the patient will be given the other eye shield than what they received after the first surgery (control groups will receive the novel eye shield and experimental groups will receive the control eye shield). They will proceed to follow identical postoperative protocols after the second surgery. A short quantitative and qualitative questionnaire directly comparing the two eye shield experiences will be provided at the 1 month follow-up after the eye surgery.

The purpose of this clinical study is to evaluate the surgical, refractive, and visual outcomes with implantation of an investigational intraocular lens (IOL).

To compare the effectiveness of an interactive mobile chatbot and traditional decision aid booklets to enhance informed decisions made by cataract patients. The chatbot was built based on large language models, and could generate ChatGPT-level responses.

Prospective, multicenter, bilateral, masked (sponsor, subject and evaluator), randomized clinical trial to evaluate the safety and effectiveness of the TECNIS IOL, Model DEN00V in comparison to an aspheric monofocal IOL.
