This is most suitable for older children and in those in whom an intraocular lens is to be implanted. This is usually used in children under 18 months of age. Modern microsurgical techniques have reduced markedly the incidence of operative and post- operative complications in infantile cataract surgery but as in all surgical procedures they can occur occasionally. Pupil abnormalities usually taking the form of an oval or off-centre pupil are quite common and mostly do not cause problems. A study from Great Ormond Street showed that in many cases the squint is relatively small and surgery was not necessary.
Retinal detachment is an uncommon but serious post-operative complication.
It may occur within months of the initial surgery but most occur 20 to 30 years after surgery. Infection inside the eye is a very rare but potentially devastating postoperative complication. Many precautions are taken to avoid this. Minor complications e.g. loose sutures are dealt with as they occur. In our unit most infants are fitted with contact lenses which we have found to be well tolerated and safe.
