NCT07408817
This study is a randomized controlled trial designed to evaluate the effect of structured teleconference-based counseling provided before cataract surgery on patients' anxiety levels and predefined postoperative outcome measures. The study will be conducted between January 31, 2025, and May 31, 2025, at a public hospital located in the Western Black Sea Region. The study population will consist of patients scheduled for cataract surgery. Eligible participants will be assigned to the intervention or control group using a simple random sampling method. Patients in the intervention group will receive structured teleconference-based counseling prior to surgery, while patients in the control group will receive standard preoperative care. Data will be collected using the Patient Information Form, the State-Trait Anxiety Inventory, the Tele-Nursing Evaluation Form, and the Patient Outcome Form. Participants will be followed up by telephone on postoperative days 1, 3, and 7. Statistical analyses of the collected data will be performed using SPSS version 29.0.

Cataracts are the leading cause of blindness worldwide, and phacoemulsification combined with intraocular lens implantation has become the most mainstream surgical approach. With advancements in surgical techniques and equipment, this procedure has evolved from a simple vision-restoring surgery into the era of refractive surgery. Patients now have higher expectations for postoperative visual quality, particularly the recovery of early vision, which directly impacts their satisfaction. Intraoperative surgical details have a direct influence on postoperative visual acuity. Thanks to intraoperative optical coherence tomography (iOCT) technology, surgeons have gradually recognized that factors such as surgical incisions and intraoperative anterior chamber collapse can affect the survival of corneal endothelial cells after surgery, which is directly related to early postoperative vision and patient satisfaction. Swept-source intraoperative OCT (SS-iOCT) has further improved imaging range and clarity, helping us discover that the depth of intraoperative ultrasound energy use (such as cumulative dissipated energy) correlates with postoperative corneal endothelial cell loss. This suggests that compared to performing phacoemulsification at the capsular opening plane or in the anterior chamber, intracapsular phacoemulsification may reduce postoperative corneal endothelial cell loss, potentially leading to better early postoperative vision, which is crucial for patient satisfaction. However, evidence is still lacking. Therefore, this study aims to compare the effects of intracapsular versus extracapsular phacoemulsification on early postoperative vision, as well as long-term visual acuity, corneal endothelial cells, corneal changes, and the incidence of intraoperative and postoperative complications.
NCT06979752
Pseudoexfoliative glaucoma is a glaucoma secondary to pseudoexfoliative syndrome; cataract surgery is often more difficult, with more complications. Tran's cannula is a single-use irrigation system designed for cleaning, with the pseudoexfoliative material remaining in the trabecular meshwork. The main objective of this study is to evaluate the efficacy of the Tran cannula, in comparison with increased irrigation, in lowering intraocular pressure (IOP) in patients with pseudoexfoliative glaucoma and treated for glaucoma, and with an indication for isolated cataract surgery.
NCT06483750
This prospective study will investigate the effect of pre-operative Systane iLux system administration in treated cataract induced dry eye disease.
NCT07362043
The goal of this observationnal study is to supplement the data collected in the pre-market study and confirm the rate of capsular ruptures due to Rx (reducing its related confidence interval). During cataract surgery, an artificial lens is placed into the capsular bag. The main question this study aims to answer is : Is Rx use associated with a rate of caspular ruptures lower than 2% ? Medical records of participants having cataract surgery with Rx laser as part of their regular medical care will be assessed in order to answer the study objective.
NCT06122103

Subjects will be assessed pre-operatively, operatively and at up to 6 postoperative visits. Clinical evaluations will include administration of patient reported spectacle usage questionnaire (PRSIQ), as well as measurement of monocular and binocular visual acuities at distance, intermediate, and near, defocus curve, manifest refraction, measurement of higher order aberrations.
NCT07297719
Main evaluation of glistening at least 24 Months post-IOL implantation
NCT07333248
This operational research project aims to strengthen continuity of eye care delivery between community screening and hospital-based treatment in rural Assam by redesigning referral pathways from the Boko Eye Care Center (ECC) to Sri Sankaradeva Nethralaya (SSDN) base hospital. Despite active outreach in the Boko region from the Boko ECC through conducting regular outreach screenings, less than 30 percent of patients referred to the base hospital actually arrive for evaluation and less than 25 percent of those advised for surgery proceed to treatment. The proposed study addresses these gaps by examining behavioural, structural and logistical barriers to referral completion and surgical uptake, and by implementing a coordinated patient-centered referral and engagement strategy. The proposed intervention comprises of five sequential components: (1) root cause analysis to identify bottlenecks and facilitators in the current referral pathway, (2) community engagement activities to improve awareness and proactive health-seeking behaviour, (3) implementation of an integrated referral and engagement model supported by trained community team and structured referral tracking, (4) strengthening referral completion through patient navigation, scheduled transport and follow-up reminders, and (5) enhancement of surgical acceptance through standardized counseling, affordability support and social reinforcement. The outcomes will be measured prospectively, focusing on increase in hospital footfall from the Boko catchment area, proportion of referred patients who complete hospital visits, and proportion of patients who were advised for surgery and had undergone the procedure. The proposed project aims to achieve a minimum of 70 percent referral completion and 45 percent surgical conversion by the end of the 36-month study period.
NCT06060041
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.
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.
NCT07317661
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.
NCT07315711
The study was designed as a prospective, observational study. Pediatric patients under 18 years of age scheduled for peripheral vascular access placement during day-case surgery or non-operating room anesthesia (NORA) will be included. The primary outcomes include time to successful vascular access, number of attempts, and number of interventions (defined as each new skin entry of the needle). These outcomes will be compared between two groups: those who receive vascular access with the aid of a vascular imaging device and those in whom such a device is not used.
