The Ridley posterior chamber lens.
In summary, if used in the way I recommend, the Copeland lens gives excellent visual results and freedom from irritation. These results are sufficiently good that they need not be compared with the results of cataract surgery without implantation of a pseudophakos. It can be pointed out that these cases were all chosen with the idea of having a successful result. One cannot pick and choose all cataract patients in this way, but one can choose patients for lens implantation in this manner and thereby ensure excellent results.
