Using lanosterol and other sterols as a clue, Gestwicki and his group assembled and tested 32 additional sterols, and eventually settled on one, which they call "compound 29," as the most likely candidate that would be sufficiently soluble to be used in cataract-dissolving eye drops.

This system separates the lanosterol molecules from the carriers in the carrier-lanosterol complex attached to the corneal surface, and then quickly passes them through the cornea, anterior, iris and pupil to deliver them into the crystalline lens. The procedure is usually performed under local anesthesia on an outpatient basis, taking less than an hour in most cases. Additionally, they injected lanosterol into the eye cavities of dogs with cataracts, then treated them with eye drops containing lanosterol for six weeks. The researchers suspected that the lanosterol prevented the clumping of proteins in the human eye. Ren L, Hu L, Zhang Y, Liu J, Xu W, Wu W, Xu J, Chen X, Yao K, Yu Y.

The measurements were carried out using a planar solid-state electrode. Considering that it is also possible that molecules other than lanosterol could play a role in human nuclear cataract reversal, specially in age-related senile cataracts, where a variety of biochemical and physical insults lead to changes in the lens proteins, determining increased protein aggregation and cataract formation. have elucidated that congenital and senile cataracts show different molecular pathways [6, 7], in particular mutations in enzymes such as lanosterol synthase and or every mutation that destabilize the lens proteins lead to congenital cataract formation due to increased protein aggregation. Would you like email updates of new search results? Nature 523 (2015): 607-11.

Modeling congenital cataract in vitro using patient-specific induced pluripotent stem cells. Recent introduction of blue light filters in computer screens and mobile phones all tell us that eye vision strain or whatever caused by these unavoidable day to day devices need to be carefully researched with high priority for a remedy. In addition, the researchers found that lanosterol is used in the body to synthesize cholesterol and several steroid hormones, but the crystalline lens of the eye also contains an abundance of this substance.
