Calcium deposits are usually caused by underlying health conditions that increase the amount of calcium produced by the body. This may include excessive vitamin D intake, renal complications, lupus, hyperthyroidism or a simple genetic inheritance. Calcium deposits are often not problematic, but deposits that are particularly irritable may be removed through surgery.Surgery for the removal of a calcium deposit in the eye is generally successful, and it is carried out using a topical anesthetic. The process involves scraping the calcium deposits away, using a surgical laser to smooth the lens of the eye and restoring normal vision if it is required.Some natural remedies include rinsing the eyes with washes composed of olive oil or aloe vera, but they are not considered effective by medical professionals.
