Randomized, bilateral, cross-over dispensing study of a standard and VR800 refraction and associated spectacle lenses.
This study is a randomized, single-masked, crossover clinical trial. There are two study lenses. Each lens will be dispensed for 3 ± 1 days and then an optimization visit will occur. The final lens pair will be dispensed for 12 ± 2 days and the follow-up on the final lens pair will occur. The second study lenses will then be fit and the above sequence repeated.
To establish, using a randomized, controlled design, the impact of near vision correction on the productivity of presbyopic textile workers in China, as measured by the change of monthly income.
A minimally invasive procedure for treating presbyopia is being evaluated to determine if there is improvement in near and intermediate vision after treatment.
A new minimally invasive procedure for treating presbyopia is being evaluated to determine if there is improvement in near and intermediate vision after treatment.
Compare functional visual outcomes and patient satisfaction of post-LASIK patients having received presbyopia-correcting IOLs versus post-LASIK patients having received monofocal IOLs
This study will be a 12-month, prospective, multicenter, open-label, non-comparative, non-randomized clinical investigation conducted at 8 to 14 sites. A total of 383 subjects will be enrolled to achieve approximately 268 treated subjects, resulting in at least 241 evaluable subjects at the point of refractive stability. After signing the informed consent, subjects meeting all inclusion and exclusion criteria in both eyes may be scheduled for surgery. The follow-up visit schedule will be the same for each operative eye.
This is a single-masked, dispensing clinical trial. A total of approximately 48 myopic and 32 hyperopic eligible subjects will be targeted to complete the study. Subjects will be fit in the study lens, optimized if required and worn for approximately 2 weeks. Subjects will then have a washout period of approximately 1 week and be refit in the lenses and be dispensed for an additional 2 weeks of wear.
Controlled, open label, prospective Post Market Clinical Follow-Up, single-center clinical study to investigate visual performance after implantation of a trifocal IOL (PhysIOL Pod L GF) in patients that underwent refractive surgery.
