What else can I help you with?
Can hyperparathyroidism cause cataracts?
Yes, hyperparathyroidism can be associated with cataracts. The condition leads to elevated levels of parathyroid hormone, which can cause changes in calcium metabolism and may affect the lens of the eye, potentially resulting in cataract formation. Additionally, the chronic effects of hypercalcemia and its impact on ocular tissues could further contribute to cataract development over time.
What does cataract?
cataract means: a decent of water over a steep surface.
How can cataract be rectified?
A cataract is when the inside of the lens in the eye clouds over and become opaque. Nowadays, the clouded lens can be replaced by an artificial one.
Can the cornea grow back?
No you cannot get cataracts again after surgery. When you have cataract surgery the lenses are removed and replaced with man made lenses. A cataract therefore is impossible to come back as there is no natural lens. Only the natural lens can get a cataract.
What is a cataract landform?
A cataract landform is a riverine or fluvial feature, where the river tumbles down over a series of boulders or small waterfalls.
Which continent would be most impact by the thinning of ozone layer?
Antarctica would be most impacted by the thinning of the ozone layer. This thinning leads to the formation of the ozone hole over the region, which increases the exposure of harmful UV radiation to the surface. This has detrimental effects on marine life, ecosystems, and can also impact human health in the region.
What is the treatment for over exposure to radiation?
Blood transfusions, protection from infection in damaged organs, and possibly the use of newer stimulants to blood formation can save many victims i
What are the differences between acute and chronic radiation exposure, and how do they impact human health differently?
Acute radiation exposure happens in a short period, causing immediate health effects like radiation sickness. Chronic exposure occurs over a long time, leading to long-term health issues like cancer. Acute exposure can be fatal quickly, while chronic exposure increases the risk of developing diseases over time.
Why Laser-Assisted Cataract Surgery?
Laser-assisted cataract surgery offers several advantages over traditional cataract surgery. The laser allows for more precise incisions, reducing the risk of complications and improving visual outcomes. It can also help soften the cataract, making it easier to remove and reducing the amount of ultrasound energy needed during the procedure. Overall, laser-assisted cataract surgery can lead to faster recovery times and better visual acuity for patients.
How long do the results of laser cataract surgery last?
The results of laser cataract surgery are typically long-lasting. Once a cataract is removed, it does not return. However, other eye conditions can develop over time, so regular eye exams are important for ongoing eye health.
What is the main cause of cataract?
The eye uses a transparent lens over the pupil with which to focus etc. A cataract is where the lens becomes cloudy and opaque (not see-through). This leads to blurred vision and if left untreated, blindness. From my A-level studies, I know that prolonged exposure to UV radiation increases the chances of developing a cataract- which is why sunglasses often have UVA/UVB ray filters in. Cataracts can be spotted by opticians by modern methods and equipment. The cataract can be easily removed (my grandma has just had hers removed). A small cut is made in the eye (after anaesthetic etc!). The cataract is removed with a rod, while a new synthetic lens is placed into the eye. The operation takes around 30 mins and has extremely high success rates. See the NHS website for more details.
Cataract surgery improves vision in what percentage of patients?
It generally improves vision in over 90% of patients.
