Under Direct Vision vs Under Non Direct Vision of Insertion of UAS in RIRS

Retrograde intrarenal surgery (RIRS) has been considered as the first-line choice for the management of <20mm kidney stones. Insertion of a ureteral access sheath (UAS) before RIRS surgery is currently accepted as an effective method to improve the effectiveness of surgery, but can be accompanied by serious complications. In long-term clinical practice, the investigators has found that many ureteral injuries occur during UAS insertion of the ureter from ureteral orifice. An...

Low Vision Depression Prevention Trial for Age Related Macular Degeneration

This randomized, controlled clinical trial, the Low Vision Depression Prevention TriAL (VITAL), will test the efficacy of collaborative low vision rehabilitation (LVR) to prevent depressive disorders in Age-Related Macular Degeneration (AMD). In this innovative intervention, a low vision occupational therapist collaborates with a low vision optometrist to develop and implement a care plan based on a subject's vision status, rehabilitation potential, and personal rehabilitation...

Timing of Low Vision Rehabilitation in Anti- Vascular Endothelial Growth Factor (VEGF) Therapy

The purpose of this research is to collect preliminary data in preparation for conducting a randomized clinical trial to determine the relative effectiveness of vision rehabilitation in improving overall visual ability (primary aim) and reducing depression (secondary aim) in patients receiving anti-VEGF therapy for neovascular age-related macular degeneratioin integrated over time.

Binocular Vision Anomalies After Cataract and Refractive Surgery

There are indications in the literature that binocular vision disorders may occur after cataract and corneal refractive surgery. It is not clear whether these problems are new or represent decompensation of previously existing conditions. However, the following significant study limitations exist in the current literature: 1) lack of attention to non-strabismic binocular vision disorders, 2) incomplete binocular vision assessment, 3) a validated symptom survey was not used, 4) ...

Comparison of Centurion® Vision System With Balanced Tip and the Infiniti® Vision System With the Mini Flared Kelman (MFK) Tip During Cataract Extraction Surgery of Hard Lenses

The purpose of this study is to demonstrate that the Centurion® Vision System used with the 45° Balanced Tip will result in less Cumulative Dissipated Energy (CDE) than the lnfiniti® Vision System used with the 45° Mini-Flared Kelman (MFK) tip during cataract extraction surgery via phacoemulsification of cataract grades NII- NIV [Lens opacities classification system II (LOCSII)].

Adult Providing Access to the Visual Environment (PAVE) - Glaucoma Pilot

We wish to evaluate a potential training program for patients with glaucoma, to become more efficient users of prescribed low vision devices for distance and near vision tasks. We hypothesize that the devices will improve efficiency. Prescribed devices will include a stand magnifier, a handheld magnifier, spectacle magnifiers for near vision, and a handheld monocular (telescope) and a bioptic telescope (spectacle-mounted telescope) for distance vision. The success of being able...

SPOT Vision Screening

The purpose of this protocol is to determine if the Welch-Allyn Spot Vision Screener (SPOT) is effective at detecting various risk factors for poor vision in developmentally delayed children. These children have a higher percentage of vision disorders than the average population. The SPOT screen itself takes about six seconds to complete. It produces a photograph of the eye and a print out with amount of hyperopia, myopia, astigmatism and pupil size. The subject will have three...

A Study to Evaluate the Raindrop Near Vision Inlay Under Flap or Within Pocket

The objective of this study is to evaluate the Raindrop® Near Vision Inlay for the improvement of near vision in presbyopes implanted under a corneal flap or within a small-incision pocket.

Prospective Internet-Registry, Postmarketing-Surveillance, Registration and Follow-up of patients after Multi-Link VISION™ - Stent Implantation

A Clinical Trial to Evaluate the Safety and Effectiveness of the Raindrop Near Vision Inlay for Pseudophakic Subjects

The objective of this study is to evaluate the safety and effectiveness of the Raindrop Near Vision Inlay implanted in bilateral pseudophakes with presbyopia for improvement of near and intermediate vision. The ReVision Optics corneal inlay is a 2.0-mm, 30-micron inlay made of a hydrogel material, implanted under a lasik flap. Subjects must require reading add from +1.50 D to +2.50 D. Subjects must have a preoperative manifest refraction spherical equivalent of -0.50 to +1.00 D...

Stress and Vision Fluctuations in Retinitis Pigmentosa

Retinitis pigmentosa (RP) patients experience a slowly progressive, unpredictable loss of vision which eventually leads to bare or no light perception, posing a continuous threat to patients' independence. Negative psychological states such as distress, sleepiness, anxiety and depression are common in RP patients due to the nature of this chronic, disabling disease. Psychophysical vision measures are more variable in legally blind RP subjects than in normally sighted individual...

Investigating Optical and Neural Causes of Vision Loss

With the aging of the population, the prevalence of age-related macular degeneration (AMD) eye disease has resulted in a large number of people suffering from central vision loss. In fact, the most prevalent cause of blindness among veterans is AMD. Since the number of elderly veterans is expected to double in the next 10 years, loss of vision due to AMD is also expected to proportionally and considerably escalate. People with impaired vision have difficulty with daily activ...
