While compound 29 and lanosterol are both promising developments in the world of cataract treatment, they still have a ways to go before they can be considered for human patients. Scientists discovered lanosterols cataract reducing ability by studying two children who had a genetic condition that caused cataracts at an early age. Office of the Surgeon General (US). It is clear what the experimental results of both Zhang's and Minija's teams mean; while lanosterol is certainly related directly to the treatment of cataracts, the simple lanosterol solution as used by both the research teams has a limitation in transferring the lanosterol molecules into the crystalline lens. In a study, the doctors applied Lanosterol eye drops to human lens cells over a period of a few months. The results were impressive: cataracts on three of the dogs completely disappeared, and there was a noticeable decrease in the opacity of the lenses on the remaining four dogs. Indian J Ophthalmol.
