Comparison of Outcomes With Multifocal Intraocular Lenses

This study is a prospective randomized controlled trial to compare and evaluate the clinical outcomes of 6 kinds of Multifocal Intraocular Lenses, the outcome measurements include postoperative visual acuity, visual quality and complications. Patients enrolled in the study will be randomized to receive one of the Multifocal Intraocular Lenses mentioned ...


Optimal Method for Mydriasis in Cataract Surgery

Recent research has compared the use of intracameral and topical agents with the preoperative pupil size and cataract surgery success. Studies have compared topical mydriatics with intracameral lidocaine and found no significant difference in dilation. , Other studies have compared topical mydriatics with intracameral dilation that includes solutions with and ...

Phase N/A

Influence of Posterior Vitreous Detachment on Retinal Detachment After Lens Surgery in Myopic Eyes

Phacoemulsification with implantation of posterior chamber lenses represents the gold standard of care for patients needing lens surgery, but there is an increased risk of developing pseudophakic retinal detachment after surgery. Especially myopic patients have an even higher risk of pseudophakic retinal detachment compared to the general population. The aim ...

Phase N/A

Outcome of Different IOLs in Patients With and Without Uveitis

Cataract, is a clouding of the lens in the eye gradually leading to reduction of the visual acuity. In most cases it can be managed with surgery, removing the own lens and replacing it with an artificial lens, intraocular lens (IOL). These lenses are made in different materials with different ...

Phase N/A

Validation of Mesopic and Photopic Contrast Vision Tests With Respect to Nighttime Driving Ability

Subjects and Methods Adult patients with a distant binocular visual acuity of 0.8 ( 16/20; habitual correction) and healthy control subjects will be included in this explorative study after informed consent. The study will be subdivided in the following (three) parts: Part 1: Validation of the Aalen driving simulator set-up ...

Individual vs Cohort Long Distance Advising for Mental Care for Congenital Cataract Guardians

Congenital cataract (CC) is the leading cause of reversible blindness during childhood, which appears at birth or during the first decade of life. Nowadays, doctors put mental health at a prior place and pay more attention to the psychological problems of ill kids' parents. In our research, we try to ...

Phase N/A

Satisfaction & Spectacle Independence With ReSTOR 2.5 & ReSTOR 3.0 IOLs

Patients desire spectacle independence for a range of distances, including distance, intermediate, and near. The ReSTOR 2.5 multifocal lens has been designed to allow better uncorrected intermediate vision and reduce glare and haloes compared to previous, higher-add models. However, their impact on overall patient satisfaction, glare & haloes (incidence and ...

Phase N/A

Comparison of Two Fragmentation Modalities in Femtosecond Laser-assisted Cataract Surgery

Femtosecond laser-assisted cataract surgery consists in nuclear lens fragmentation, followed by ultrasound phacoemulsification of nuclear lens, which is then removed. It can be assumed that fragmenting the nuclear lens in more pieces could facilitate the post-laser ultrasound phacoemulsification to extract the lens, with a lesser amount of ultrasonic energy. The ...

Phase N/A

Choroidal Reflectance Camera for the Detection of Congenital Cataracts

All babies born in the United Kingdom undergo eye screening at birth and 6-8 weeks to enable the early diagnosis and management of congenital cataract, a treatable but potentially blinding condition affecting 1 in 2000 newborns. The current technique involves the assessment of the "red reflex" - the orange/red glow ...

Phase N/A

Music Listening for Cataract Surgery

Cataract surgery is the most frequent surgical procedure performed in Europe, usually done under topical anaesthesia. Restlessness and hypertension are the most frequent medical complications during surgery, potentially leading to surgical complications. Since the surgery is ambulatory and requires the patient's cooperation, heavy intravenous sedation should be avoided. However, this ...
