Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To determine the efficacy of Lenstatin™, an over-the-counter nutritional supplement, in inhibiting the progression of nuclear cataract in eyes after pars plana vitrectomy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

BACKGROUND AND RATIONALE

There are conflicting reports on the effectiveness of nutritional antioxidants in preventing or slowing the growth of age related cataracts, despite extensive laboratory evidence suggesting that oxidative damage to lens epithelial cells is a common underlying etiologic factor in cataractogenesis. One reported review of nine clinical trials involving over 117,000 patients suggested that beta-carotene, Vitamin E, and Vitamin C had no effect in preventing or slowing the progression of age-related cataract. Conversely, a randomized trial of over 14,000 US male physicians indicated that long-term daily multivitamin use modestly and significantly decreased the risk of cataract.

Cataract formation following pars plana vitrectomy is a well recognized post-operative complication of the procedure, with the reported incidence of clinically significant cataract development as high as 80% within 2 years after pars plana vitrectomy.

INVESTIGATIONAL AGENT

Lenstatin™ is a proprietary formulated nutritional supplement containing 11 micronutrients and anti-oxidants intended to be taken for the nutritional support of the human crystalline lens.

INTERVENTION

Participants will be randomized to treatment with Lenstatin or Placebo for (6) months following pars plana vitrectomy.

STUDY METHODS

Participants will have baseline nuclear density (cataract) measurements using the Pentacam Nucleus Staging (PNS) program. The Pentacam Scheimpflug imaging system is a non-contact and non-invasive anterior segment imaging device which has been shown to provide an immediate, quantitative, examiner-independent measurement of lens density which correlates with the LOCS III cataract grade. Serial Pentacam nuclear density measurements will be taken on each participant at (1) month intervals for (6) months.
