Intraocular Lens Power Calculation After Laser Refractive Surgery Based on Optical Coherence Tomography

This study is about a new imaging method to study the front part of the eye. This imaging method is called Optical Coherence Tomography (OCT) which provides detailed cross-sectional (layered) views of structures in the eye. The OCT system scans a beam of light across the eye to take a ...

Phase N/A

Non-genetic Risk Factors of Congenital Cataracts

Prevention and treatment of the reversible childhood blindness, including congenital cataracts (CC), has been listed as a significant component of the international programme "VISION 2020 - the Right to Sight" launched by WHO in 1999. However, there is still a lot of unsolved problems regarding to CC, especially in developing ...

Phase N/A

Evaluation of Cataract Surgery Outcome

The purpose of this study is to evaluate the visual outcome of the cataract surgery, including best uncorrected and corrected visual acuity, spherical equivalent, wavefront aberration and other measurements.

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 ...

Phase N/A

Comparison of Femtosecond Laser Assisted Cataract Surgery to Conventional Phacoemulsification Cataract Surgery

This study will only include patients who are eligible to undergo cataract surgery. All patients will receive treatment that is FDA approved for cataract surgery. Because all study participants will have been scheduled for elective cataract extraction regardless of their participation in this study, there will be little or no ...

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

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

Shanghai High Myopia Study

High myopic cataract (HMC) has become a major high-risky type of cataract in China, which accounts for nearly 30% of cataract in recent years. Compared to age-related cataract, HMC is characterized with earlier onset, severer lens opacities, higher incidence of vitreoretinopathy and postoperative complications compared to age-related cataract(ARC). The main ...

Phase N/A

Measurement of Ocular Tensional Fluctuation by Triggerfish Lens Before and After Cataract Surgery in Patients With Exfoliative Glaucoma

Glaucoma is a very frequent disease in Brittany. In glaucoma the retinal ganglion cells and their axons slowly die with visible changes at the optic nerve head (cupping). Without early diagnosis and effective treatment or with delayed treatment decrease of visual acuity or blindness become. In secondary pseudoexfoliation glaucoma grayish-white ...

Phase N/A

Corneal Sensation and Incidence of Dry Eye Post Refractive Cataract Extraction With FemtoSecond Laser

The study objective is to assess changes in corneal sensation and dry eye signs and symptoms following cataract extraction/femtosecond arcuate relaxing incisions. Our clinical hypothesis is to determine if a combination of cataract surgery and femtosecond arcuate relaxing incisions lead to a reduction in corneal sensation and the onset or ...
