Ocular Clarity After Cataract Surgery With Two Different Phacoemulsification Systems

After cataract surgery, the lens is surgically extracted, after which a clear artificial intraocular lens is implanted. For patients, it is critical that they regain functional vision as soon as possible after surgery, as a poor vision can increase the risk of falling and increases dependence on others. The key differences between phacoemulsification methods are the used pump model, the way the needle oscillates, and the system's fluid dynamics.

Visual Function and Patient Satisfaction in Glaucoma or Ocular Hypertensive Patients Undergoing Simultaneous Cataract Surgery and i-Stent Implantation

With simultaneous implantation of an expanded depth of focus IOL, the Vivity IOL, the purpose of this research is to report in detail: the aim of this research is to document in detail how visual function and patient satisfaction in patients with glaucoma and ocular hypertension undergoing cataract surgery with increased depth of focus. The investigation also looks to see if there are any differences in the speed of visual improvement between patients undergoing isolated cataract surgery and those undergoing simultaneous i-Stent implantation. With a group of patients with no ocular pathology undergoing cataract surgery with Vivity implantation, the results can also be compared to a group of patients with no ocular pathology undergoing cataract surgery. Patients will be invited to enroll in the trial after the type of surgery and the type of lens to be implanted has been decided between the ophthalmologist and patient.

Safety and Effectiveness of Single-dose Subconjunctival Triamcinolone Compared to Topical Prednisolone Eye Drops in Manual Small Incision Cataract Surgery

Eye drops administered following cataract surgery for the prevention of post-operative inflammation can have several drawbacks, including cost and poor medication use. Following manual small incision cataract surgery in Guatemala, manual small incision cataract surgery is a randomized controlled trial comparing the results of single-dose subjunctival triamcinolone administration at the time of surgery to the usual 4-week taper of topical prednisolone drops. Patients will be screened at post-operative weeks 6 and 12, using the key outcome measures of intraocular pressure and best corrected visual acuity. Data on the occurrence and amount of corneal edema, anterior chamber inflammation, and the formation of macular edema will also be obtained.

Impact of Music Added to the Usual Treatment on the Anxiety of Patients Undergoing Outpatient Cataract Surgery With Topical Anesthesia: Randomized Controlled Trial

A short outpatient course with topical anesthesia is the most effective for cataract surgery for patients treated for cataract surgery. Often waiting in a waiting room with other patients can escalate this anxiety. Patient anxiety can rise blood pressure, possibly leading to the prescription of nicardipine to encourage surgery. Patients with anxiety are unlikely to have many choices beyond the drug use. In several studies, the effects of music on preoperative anxiety has been studied, and it has resulted in a significant decrease in anxiety prior to surgery. MusicCareU00ae is a "digital therapy" based on the principles of hypnoanalgesia, which has been tried in the treatment of patients with a variety of pathologies and has demonstrated relative success. Patients' anxiety about absence in the aftermath of cataract surgery with topical anesthesia, we would like to investigate the impact of providing the MusicCareu00ae listening device on patients' anxiety about absence.

Evaluation of the Efficacy of LipiFlow Thermal Pulsation Treatment Performed Before Cataract Surgery in Patients Affected by Meibomian Gland Dysfunction in Reducing Postoperative Dry Eye Disease

Dry Eye Disease is a disorder of the ocular surface that can be related to a variety of conditions, including cataract surgery. In addition, it is a risk factor for DED exacerbation after cataract surgery, which can be present in approximately 40% of cases. Hence, the ocular surface before cataract surgery should be stable to ensure improved post-operative comfort and a more stable refractive result. The introduction of LipiFlow thermal pulsation treatment provides a controlled means of squeezing the obstructed Meibomian glands by applying heat to the upper and lower eyelids and simultaneously applying pulsatile pressure to the eyelid skin surfaces. In lowering postoperative DED, the aim of our research will be to determine the effects of preoperative LipiFlow therapy in patients with age-related cataracts and mild to moderate MGD.

Comparison of Corneal Endothelial Cell Loss and Cumulative Dissipated Energy Between Femtosecond Laser Assisted Cataract Surgery and Standard Phacoemulsification With the Active Sentry or OZil Handpiece

The femtosecond laser is a new technology that is being used for cataract surgery. The LenSx laser is one of the most commonly used LFS for cataract surgery and is part of the CENTURION Vision system. Optical Coherence Tomography's high-resolution, real-time visualization of ocular structures and their dimensions is provided by the Frequency Domain - Optical Coherence Tomography optical imaging system. The traditional handpiece is named OZil and is part of the Infiniti Vision System, which was launched in 2006 and has since revolutionized the phaco technique with its new rotational technology. However, a new generation of handpieces, Active Sentry, which is part of the new Active Fluidics, has the capability of measuring the pressure inside the eye in real time and adjusting it to prevent significant variations. The number of endothelial cell death as well as the amount of energy needed to fragment the lens are both measures of collateral damage caused by cataract surgery. FLACS can reduce the eye's corneal damage caused by phacotic phaco. When compared to standard phaco, few studies have shown an increase in ECL as well as CDE in patients undergoing FLACS, as well as CDE, but long-term results were not conclusive. In addition, the investigators predict that patients receiving standard phacoemulsification with the Active Sentry handpiece will have less corneal endothelial cell damage and require less CDE than those who receive standard phacoemulsification with OZil.

Quality of Life and Uncorrected Binocular Visual Acuity (UBVA) Evaluation in Patients Undergoing Cataract Surgery Using 4 Different Types of Lens Implant Combinations: a Multicenter, Prospective, Comparative and Randomized Study

The most common surgical procedure in France is cataract surgery by ultrasonic phacoemulsification. This is a presbyopia compensation scheme that aims to produce a small myopization of one eye for nearsightedness, with the other eye being intended for distance vision. Patients' expectations regarding vision and freedom from glasses are likely to remain high, though patients themselves are increasingly aware of the presence of multifocal implants. In addition, there is also a lack of scientific consensus regarding implants, during a surgical treatment of cataract lenses by phakoexeresis, for otherwise healthy eyes, and in a field that seeks to no longer wear glasses postoperatively. Different studies have appeared comparing the bilateral implantation of various types of multifocal implants with each other, but no research has been conducted into mixed batches of'mix - match' implants.
