[Opacification of the crystalline lens after trabeculectomy. Study of 95 cases]

In a study of lens opacification following trabeculectomy in 95 cases observed for 6 months to 2 1/2 years. 28 per cent were found to have lens opacities within an average of one year. Post-opérative complications do not determine the development of cataracts, but they are a predisposing factor chiefly acting on the delay in opacification. It seems that the contribution of trabeculectomy in reducing the frequency of flat anterior chambers and prolonged hypotony when compared with the classical fistulising operations, can only delay the appearance of post-operative cataracts without diminishing the frequency. This frequency reaches 50 per cent after the age of 70 in the same titre as the classical fistulising procedures.
