Ophthalmic Surgery Cataract Surgery

Cataracts may be congenital, traumatic, steroid- or radiation-induced, or degenerative. In degenerative cataracts there will also be other medical conditions of the ageing population. While diabetics have no more cataracts than the general population, they tend to present earlier and so there seems to be a preponderance of diabetic patients presenting for cataract surgery. Steroid induced cataracts present in patients taking long term steroids for other conditions, particularly eczema or asthma which should be taken into account. Cataract surgery demands a still eye with low intra-ocular pressure. This can usually be achieved by smooth anaesthesia with muscle relaxation and IPPV to achieve mild hypocapnia, whether via a tracheal tube or laryngeal mask, though the latter is preferable because of the lack of intubation pressor response or laryngeal spasm and coughing on extubation. There is a fashion for local anaesthesia for cataract surgery despite this having a higher failure rate, more complications and less predictable reduction of intra-ocular pressure. Patients who cannot lie flat without coughing or distress or cannot communicate because of language, deafness or dementia cannot safely have their cataract surgery under local anaesthesia. They may or may not be fit for general anaesthesia.
