Filter by:The purpose of this study is to verify the post-market safety of the IC-8 Apthera IOL after the treatment of posterior capsular opacification (PCO), an expected complication related to IC-8 Apthera IOL implantation.
The aim of this study is to compare the surgical outcomes of the two IOL implantation methods for eyes with cataract and PEX in a single-center and with highly experienced surgeons. The goal is to acquire relevant information regarding these two IOL implantation techniques, which will help surgeons to decide which approach to choose, ultimately resulting in a benefit for patients with PEX syndrome who require cataract surgery. The main questions are: Is there a difference in lens tilt and decentration between the both methods. Is there a difference in the frequency and amount of capsular phimosis between the both methods.
The purpose of this research is to investigate the effects of ripasudil administered as an ophthalmic solution in patients with FED after femtosecond laser assisted cataract surgery. The secondary aim is to identity the characteristics of patients who will benefit the most with the use of ripasudil based on the test results obtained from this study.
Cataract surgery is one of the most frequently performed surgical interventions worldwide. The microscope light-induced retinal toxicity after cataract surgery has been described in several reports even in short procedures; however, this potential toxicity has not been evaluated by objective criteria. Indeed, this retinal phototoxicity would be increased for patients with mild macular diseases such as early stages of AMD (Aged Macular Degeneration) (ie: drusen) which are frequently associated in elderly patients with cataract. The aim of the study will be to assess the potential functional macular effects by focal and multifocal ERG after cataract surgery with NGenuity by comparison to Standard Operating Microscope (SOM). This study would particularly address eyes at risk for macular toxicity like patients with early or intermediate AMD
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 goal of this clinical trial is to look at the difference in pressure lowering effects in patients having two different combinations of minimally invasive glaucoma surgery (MIGS) at the time of their cataract surgery. Eligible patients will have mild to moderate glaucoma and be candidates for cataract surgery. The trial will look at the eye pressure before and one year after cataract surgery in patients. One eye in each patient will have cataract surgery with canaloplasty using OMNI. The patients other eye will have cataract surgery with canaloplasty and a HYDRUS stent. The trial will look at the differences in eye pressure and if patients are able to need fewer eye pressure lowering drops after surgery. Study participants will undergo preop testing of pressure, vision, slit lamp exam, ocular coherence tomography (OCT) of the nerve fiber layer (NFL) analysis, and visual field prior to cataract surgery with MIGS. One day, one week, one month, 6 month, and 1 year exams will be performed to check pressure, vision, slit lamp exam, and number of necessary eye pressure medications in each eye.
In case of instability or rupture of capsular bag occurs during cataract surgery, Yamane technique is one of the options to fix intracocularlens' haptics. Yamane technique uses a double-needle technique that seamlessly fixes the haptics intrascleral by creating a scleral tunnel. Aberrations, IOL tilting or even dislocations might occur and influence the final outcome of IOL implantation. The aim of this study is the evaluation of the postoperative tilt of Kowa PU6AS using Yamane technique. Furthermore of the corrected and uncorrected visual acuity and the anterior chamber depth are being developed.
This trial hypothesized that novel laser refractive surgery techniques (PRK, LASIK, SMILE) or laser-assisted cataract surgery (FLACAS) could suppress postoperative inflammation and improve recovery in patients by reducing oxidative stress generated by the surgical procedure. It is also intended to verify whether the new laser technology is necessary for clinical use in groups with low antioxidant activity through the detection of antioxidant activity in the eyes of patients.
The objective is to assess refractive accuracy of the Alcon Vision Suite (with Argos biometer) following Clareon PanOptix and AcrySof Vivity IOL implantation.
This is a prospective randomised open-label study with the aim to compare the visual performance of the premium monofocal Isopure IOL versus the extended depth of focus Eyhance® IOL after phaco-emulsification cataract surgery.
