Hello Mohammed, even though I am not an Ophthalmologist and don't practice cataract surgery, I know that Albrecht Hennig has done quite a bit of work on this matter, so please have look at his work.
Thank you Nabin. I have seen his article on SICS in the Community eye health journal but that did not discuss trabbies. I have been unable to get the relevant article. I would appreciate a link if possible.
