Summary: This is a study to evaluate the safety, effectiveness and patient satisfaction of the Trifocal Intraocular Lens after implanted to replace the natural lens following cataract removal.

Summary: This is a prospective, multicenter, single-arm, open-label clinical study of the commercially available TECNIS Multifocal Toric 1-Piece IOL. The study will enroll up to 120 subjects from up to 5 sites in China. The subjects will be followed for 12-months postoperatively.

Summary: Currently, surgical training is often conducted using the traditional apprentice model, where a trainee observes a qualified surgeon and learns from him/her, and then the surgeon supervises the trainee performing surgery on a patient. The investigators believe that this conventional model has substantial limitations and drawbacks, making surgical training less efficient and less safe.The investiga...

Summary: The objective is to evaluate refractive stability (spherical equivalent change ≤ 0.50D from 1-month to 3-months).

Summary: There is strong consensus - based on robust randomized trial data - that routine pre-operative (pre-op) testing for cataract surgery is inappropriate. Despite these widely endorsed evidence-based recommendations, most seniors undergoing cataract surgery still receive unnecessary blood testing, EKGs, and chest X-rays (CXRs); another substantial percentage even undergo nonindicated cardiac stress te...

Summary: This study is a 6-month, prospective, multicenter, randomized (1:1:1), subject-masked and evaluator-masked, bilateral clinical investigation of the TECNIS IOL Models C1V000 and C2V000 versus the TECNIS Eyhance™ Model ICB00 IOL.The study will be conducted at up to 15 sites in EU, AU, NZ and/or AP and will enroll up to 225 subjects to achieve approximately 67 bilaterally implanted subjects in each l...

Summary: Evaluation of the clinical safety and effectiveness of an hydrophilic acrylic intraocular lens

Summary: 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 ...

Summary: To evaluate the influence of the visual acuity after congenital surgery on the retinal and visual cortex structure.

Summary: 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.

Summary: Mainstream oximetry devices use two-wavelength systems to photograph the retina and estimate the oxygen saturation levels in the retinal vessels by comparing light absorption in the blood of the vessels at the selected wavelengths. This method limits the measurements to large retinal vessels, depends heavily on calibration and is non-reproducible across machines. The few numbers of wavelengths use...

Summary: Multiple intraocular lens are nowadays available for implantation after cataract surgery. They use different technology to try to improve patient spectacle independence. It is necessary to better characterise the performence of each type of lens, as well as to define how they are affected by residual refractive errors. The purpose of this study is to evaluate visual function in patients implanted ...
