We analyzed a case involving a 74-year-old man who experienced ongoing blurred vision after cataract surgery. His condition included persistent damage to the corneal epithelium, which raised concerns over the underlying reasons for his visual impairment.
To investigate, we recorded his full-field electroretinograms (ff-ERGs) to assess both scotopic and photopic responses of the retina. We also performed optical coherence tomography (OCT) to visualize changes in his retinal structure. Laboratory tests revealed a critically low level of vitamin A in his blood.
Given these findings, we diagnosed him with vitamin A deficiency (VAD) and initiated treatment with oral vitamin A supplements. Remarkably, after three months, we noted significant improvements: his visual acuity, ff-ERGs, and OCT results returned to normal. This highlighted the potential of vitamin A in managing visual issues related to cataract surgery.
Our findings suggest that vitamin A plays an important role in recovery from eye surgeries, especially for patients like him who experience corneal damage and impaired vision. We believe this case underscores the importance of monitoring vitamin A levels in patients presenting with similar complications.

We explored the effects of antioxidant supplements, specifically beta carotene and vitamins C and E, on cataract progression in a rural South Indian population. Using a rigorous 5-year, triple-masked, placebo-controlled trial design, we carefully monitored nearly 800 participants.
Despite high compliance and thorough examinations, we observed no significant benefits from these antioxidant supplements in slowing cataract progression. The study suggests that even in populations with low dietary antioxidants, these supplements may not offer the hoped-for protection against cataracts.

We explored the relationship between dietary vitamin A and cataract development in lumpfish, a species known for its susceptibility to this eye condition. Over 18 months, lumpfish were fed diets supplemented with varying levels of vitamin A—5000, 15,000, and 120,000 IU/kg. Throughout this period, we monitored the fish for changes in weight, cataract frequency, and severity.
Our findings revealed that lower levels of vitamin A significantly reduced the occurrence of cataracts in adult lumpfish, and led to less severe cataracts, particularly notable in male fish. However, as vitamin A intake increased, we observed a positive correlation with higher oxidative stress levels in the lenses, which are associated with cataract formation.
Additionally, tissues from fish with severe cataracts exhibited high levels of cell death, known as apoptosis. This suggests that excessive vitamin A may contribute to oxidative stress and subsequently influence the development of cataracts in lumpfish. In essence, while vitamin A plays a crucial role in these fish, its higher concentrations seem to exacerbate, rather than alleviate, eye issues.

We examined the connection between vitamin A and cataracts, particularly its role in dietary sources versus supplements. Our findings indicated that vitamin A, when consumed through food, seems to offer a protective effect against cataracts. This is an encouraging note for those looking into nutritional strategies to support eye health.
On the other hand, when vitamin A is taken in supplement form, we observed a contrasting outcome—it did not provide the same benefits. In fact, it might not be as effective in preventing cataracts as previously thought. This shows us that getting nutrients from a balanced diet is crucial, while high doses of supplements could be less helpful, or even risky, for eye conditions.
Overall, our exploration suggests a focus on whole foods rich in vitamin A as a smarter move for those concerned about cataracts, rather than leaning on supplements.

We investigated how Luffa cylindrica (LCE) fruit extract might influence cataract formation, particularly focusing on the oxidative stress markers associated with this condition. In a laboratory setting, isolated goat lenses were exposed to hydrogen peroxide—a known cataract inducer—for 72 hours at body temperature.
We tested several concentrations of LCE, from 5 to 30 µg/ml, alongside a control group. Throughout the incubation, we examined the lenses for any changes in appearance and transparency. Notably, we measured biochemical markers, including superoxide dismutase (SOD), reduced glutathione (GSH), total protein content (TPC), and malondialdehyde (MDA)—essential indicators of oxidative stress.
Our findings revealed that SOD, GSH, and TPC levels increased with higher concentrations of LCE, suggesting the extract's potential protective effects. Conversely, MDA levels decreased, indicating reduced oxidative stress. The lenses treated with 25 µg/ml of LCE maintained clarity for a significant duration, showing that this level of extract could potentially delay or prevent cataract progression.
While our study highlights the benefits of LCE related to its antioxidant properties, the exact contributions of Vitamin A in this natural extract, while noted, were not isolated for specific effects. Overall, our research underscores the importance of exploring natural remedies like Luffa cylindrica in fighting cataract development, paving the way for future studies to fully harness its potential.

We explored the connection between blood antioxidants, like beta carotene and vitamin C, and cataracts in individuals aged 50 and older from various villages in North India. Our cross-sectional study involved interviews and lens photography to get a clear picture of eye health.
While we found that lower levels of antioxidants were associated with higher odds of cataract formation, the evidence primarily highlighted vitamin C, zeaxanthin, and retinol.
Notably, beta carotene specifically did not show a significant benefit. Overall, the results indicate that increasing blood antioxidant levels may help reduce cataract risk.

Excellent product! It promotes eye health, prevents vision loss, and reduces the risk of cataracts. Beta-carotene enhances brain function, concentration, and memory. It also aids in healing wounds and protects the skin from sun damage. As a precursor to vitamin A, it should be consumed with fats for better absorption. I've developed a regimen to take it on the first 10 days of each month. The product’s quality from a well-known brand is very reassuring.

Improved eyesight
I noted in my reviews that if you take vitamin D3 in the morning and beta-carotene in the evening, it positively affects your complexion. My son used to tan evenly until he turned twelve, after which he became pale and could only burn his nose. Recently, we learned about beta-carotene, and since taking it in autumn and winter, his complexion has improved from pale to a more even tone, which I’m very pleased about. I have poor eyesight and had difficulty reading, even with glasses and a magnifying glass. However, after taking beta-carotene, I can read with my glasses and occasionally without them. Though I have senile cataracts, my eyesight has improved significantly, and the foggy effect is gone. I definitely recommend it as it has helped me greatly.

We explored the impact of nutritional antioxidants on the prevention of cataracts, focusing on various micronutrients such as vitamins A, C, E, and carotenoids. After examining 25 studies involving nearly 300,000 participants, we found that beta carotene showed some protective effects against cataract development, with statistical significance. However, it's important to note that not all antioxidants evaluated, including vitamin E and A, demonstrated significant benefits. More research, particularly interventional studies, is necessary to better understand these relationships.

We explored the relationship between dietary vitamins and carotenoids, like beta carotene, and the risk of age-related cataract (ARC) through a review of various studies. While cohort studies indicated that higher intake of these nutrients can significantly reduce ARC risk, the results from randomized controlled trials were not as conclusive for beta carotene specifically.
In these trials, beta carotene did not demonstrate a significant effect compared to placebo. However, the evidence from cohort studies suggests that increasing beta carotene intake may still benefit overall eye health.

We aimed to see if there's a link between blood antioxidants and vitamin levels and age-related cataract risk through a thorough review of 13 studies involving nearly 19,000 participants. Our findings indicated that some antioxidants like vitamin E, α-carotene, lutein, and zeaxanthin were indeed linked with a lower risk of cataracts.
Notably, beta-carotene did not show significant benefits in preventing cataracts, with an odds ratio indicating no strong association. This suggests a need for more targeted studies to further explore the potential of these nutrients in cataract prevention.

We reviewed various clinical trials that examined the role of nutritional supplements, including beta carotene, in treating age-related cataracts and macular degeneration. Our findings indicate that beta carotene didn't show a significant benefit for cataracts and, in fact, was linked to a higher risk of certain cataract types.
While some trials showed multivitamins might reduce cataract progression, the benefits of beta carotene were overshadowed by concerns about lung cancer risk for former smokers. Therefore, alternatives like lutein and zeaxanthin are suggested for future studies.
