Conclusion Implantation of posterior chamber intraocular lens with "C" loops, can make a distance between iris and intraocular lens, for its optical part nestling up to posterior lens capsule, which can make aqueous fluid circulation unobstructed, and intraocular lens don' t stimulated the iris and ciliary body, so the reaction and the complication were few.
Conclusion: Open type artificial iris diaphragm implantation in eyes with longstanding silicone oil tamponade can effectively prevent the silicone oil from cotacting the cornea causing complication by spontaneously blocking and rescuing anterior chamber fluid circulation.
Laser peripheral iridoplasty(LPI) and iridectomy are both for intraocular drainage. They do a little change on the structure of anterior segment and even it is failed, other treatments will be performed.
The tradition was the front way circulation, that is the way of trabecular schlcmm tube, only one way in aqueous circulation and lasting more than one hundred years.
We called it one way theory of aqueous circulation. That the behand way circulation was fund became a supplement of the former, a lot of evidence in ana tomy, physiology and clinic showed that there was another way circulation
Conclusion Liguid or gas injection to anterior chamber can make the crystalline lensiris move formard and return to normal position,maintain the intraocular pressure and the aqueous humor circulation return to normal.
