Lemon juice or a dozen lemon drops (+/-) in a little water (boiled and cooled to room temperature) and wash your open eyes with it. As your eyes get better it will sting less and less. Sometime in the beginning of last century there was a doctor who dissected both normal and cataractic eyes. The striking difference he found was the lack of vitamin C in the middle of the cataractic eyes. This you can do forever.
Castor oil also works as it has a lot of omega oils. But you need to make sure it comes from a reputable source. That means that it probable brings a certificate of analysis with it. The reason being that some of the producers may not have the means/habit of being thorough about its purity. If you can get it from a chemists that is ideal.
The ideal is probably, much later on after recovery, and only every so often to put a few castor oil drops before bedtime.
What I found is that the reversal has to be maintained and every case is different. So you need to pay attention to your individual needs.
To be safe you do not put anything in your eyes that you would not eat/drink. (the inverse is not true! :D)
Serrapeptase is really good. Make sure you are not (at the same time) taking meds to thin the blood.
You should also eat raw leaf greens + 1 carrot (medium size - there are daily limits - this is safe) + green apple. And whatever other raw (organic preferably) veg or fruit you wish. You can either do a smoothie or juice it.
Another important thing is to do eye exercises (never force). You will find useful ones on youtube.
