NCT07325188
This study aims to assess the accuracy of toric intraocular lens (IOL) alignment axes as calculated and displayed by a novel digital guidance system. In addition, it evaluates the time required to initiate surgical guidance and postoperative refractive astigmatism following toric IOL implantation. This single-surgeon, single-site, prospective, non-invasive observational study evaluated the accuracy of toric IOL alignment axes calculated and displayed by the digital guidance system (Cassini Technologies, B.V.) in 100 eyes. The intraoperatively calculated alignment axes were compared to preoperative measurements to assess their accuracy (in degrees). Postoperative outcomes, including residual refractive astigmatism (diopters) and visual acuity (Snellen), were recorded at 1 month postoperatively.

Patients with cataracts disease need to choose what type of artificial lens will go into their eye prior to surgery date. Some lenses are standard and are usually covered by insurance. Other "premium" lenses have various benefits such as reducing the need for glasses but usually require out-of-pocket costs. The combined busy outpatient clinic and complexity of artificial lens choices in the ever-changing world of cataract surgery tends to lead patients confused about their available lens options. There is an abundance of educational material present in premium lenses, however these are limited by accessibility and are standardized at single educational levels. Therefore in the present study, we want to test whether giving patients a short LLM powered AI-guided explanation from Custom GPT from OpenAI of lens options prior to their consultation with their doctor can improve visit efficiency, physician explanation and patient understanding of lens options. We will compare two groups: standard of care versus standard of care plus AI education. The LLM in this study is intended to provide supplemental information about premium intraocular lens(IOLs) options to study participants, and is no means supposed to replace a health care professional in the diagnosis, cure, treatment, and/or mitigation of disease. Study is analogous to giving a verified health pamphlet to a patient for them to view and learn different IOL options, in other words, facilitating patient understanding of their options. The LLM will be trained by several health care professionals and MD specialists to provide sufficient instructions. Sources will include verified online resources and MD information. The investigators hope to learn if a large language model-based educational tool can improve visit efficiency, physician explanation and patient understanding of intraocular lens options. New knowledge of this study could guide how cataract counseling is delivered in the future and may help clinics spend more time on individualized questions instead of repeating generic information.
NCT07223866
The study will pertain to investigating the impact of high vs low IOP on the intraoperative experience and comfort for the patient and surgeon. Our hypothesis is that operating at a more physiological IOP using Unity VCS/CS and Centurion with Active Sentry at a higher, or more traditional IOP will result in significantly less discomfort/pain as assessed by the decreased need for rescue medication and lower VAS scores.

Study Goal The goal of this clinical trial is to compare how well four different types of artificial lenses (called intraocular lenses or IOLs) help people see after cataract surgery. The main questions it aims to answer are: Which lens gives the best vision at different distances (far, middle, and close)? How satisfied are patients with their vision after surgery? How often do patients still need glasses after surgery? Who Can Participate Adults aged 22 to 85 years who need cataract surgery in both eyes and meet specific health requirements. Study Design Researchers compared six different lens types: TECNIS Eyhance - designed to improve middle-distance vision AcrySof IQ Vivity - extends the range of clear vision LuxSmart - uses special optics for better depth of focus Rayner EMV - uses gradual light-bending technology for smooth vision transition Eycryl SERT - modifies light focus to extend clear vision range CT ASPHINA 409M - standard single-focus lens (comparison group) Participants chose their preferred lens type after learning about each option's benefits and limitations. What Participants Do? Participants will: Have cataract surgery on both eyes (1-2 weeks apart) Complete vision tests at multiple distances Take contrast sensitivity tests under different lighting conditions Fill out questionnaires about vision quality and daily activities Attend follow-up visits at 1 day, 1 week, 1 month, and 3 months This study helps patients and doctors make informed decisions about which type of artificial lens might work best for individual needs and lifestyle.
NCT06717607
The purpose of the study is to determine if visual function is improved with implantation of a low-cylinder toric intraocular lens, relative to a non-toric intraocular lens.
