Subjective Comparison of Pre-Lens Tear Film Stability With Daily Disposable Contact Lenses

MyopiaHyperopia1 more

The purpose of this study was to compare three CE-marked daily disposable contact lenses for tear film stability as measured by pre-lens non-invasive keratograph break up time (PL NIK-BUT). Secondarily, contact lens surface wettability was assessed.

Anesthetic Impregnated Bandage Soft Contact Lens (BSCL) in Pain Management After Photorefractive...

MyopiaHypermetropia2 more

Compared to laser-assisted in situ keratomileusis (LASIK), Photorefractive Keratectomy (PRK) is associated with more discomfort and requires more downtime. However, it is oftentimes considered the preferred method of refractive surgery for patients with dry eye syndrome, high refractive errors, thin corneas, or those with more active lifestyles who may be more prone to dislodging their LASIK flaps. We hypothesize that the use of bandage contact lenses soaked in proparacaine will decrease pain levels compared to solely the use of bandage contact lenses after PRK.

Performance of a Photoscreener for Vision Screening in a Haitian Pediatric Population

AmblyopiaMyopia8 more

Screening of haitian children between the ages of 3 and 6 years old for amblyogenic risk factors with the use of the Spot photoscreener. The photoscreener results will be compared to the complete ophthalmologic evaluation. Primarily, this will allow evaluation of the performance of the spot photoscreener in the haitian children population. Secondarily, this study will gather epidemiological information on vision problems in the haitian children population.

Complete Easy Rub Comparative Efficacy Study

MyopiaHyperopia1 more

The aim of this trial is to assess Complete Easy Rub compared to a competitor multi-purpose solution in terms of lens cleanliness, subjective response and ocular response, when lenses are worn bilaterally on a daily wear basis for two months. The hypotheses for this trial are: Lens cleanliness measures between solutions will be no different. Subjective ratings between solutions will be no different. Ocular response between solutions will be no different.

Refractive Accuracy of "2WIN" and Portable Autorefractors

Refractive Error - Myopia AxialAstigmatism3 more

Youth and some adults have photoscreening refractions and hand-held auto refraction before cycloplegia refraction during new and follow up eye examinations. Vector math is applied to each refraction to determine how closely the hand-held "dry" devices match actual refraction.

Comparing Low-cost Handheld Autorefractors - a Practical Approach to Measuring Refraction in Low...

MyopiaHyperopia

Study compares four portable vision measurement and eye-imaging technologies in terms of accuracy and time and ease of use with older adult (ages 40-100) participants in a developing-country setting (India). Specifically, the five portable devices will be measured against the baseline of the traditional eye-examination techniques, including the use of eye charts and phoropters.
