Children appear to be very suitable for this type of aphakic correction, the lens being fitted at the time of aspiration of congenital or traumatic cataract.

The Fitting of Continuous Wear Soft Contact Lenses at the Time of Cataract Surgery
The work of Binkhorst and others has shown that the intraocular artificial implant is in many cases a feasible and safe answer to the problem of the correction of aphakia. In our Department we have many patients who have obtained very satisfactory results from wearing different types of artificial lens, following trials extending over several years. However, it seems wise to continue the search for alternatives, not only for the case where an implant is not advised but also to encourage research into finding eventually a more perfect solution.
During the past eighteen months we have been investigating the use of a high oxygen permeability hydrophilic contact lens for 'continuous' wear (Pierse & Kersley 1976). The lens is fitted at the time of surgery and left in place for about six weeks. At this stage a final definitively fitted lens of similar material is exchanged for the original lens and this remains in place until routine review indicates the need for cleaning or removal. The use of a backward-shelving comeal incision (Pierse 1975) and the protection and support of the lens gives rise to a quiet rapidly healing postoperative course, and the patient has useful vision in the immediate postoperative stage.
Complications Infection, though not common, is the most serious and must be guarded against carefully. Local antibiotic when indicated, regular observation, and firm instructions to, the patient to
