The Prince of Wales Hospital prospective aphakic macular oedema study.

A two year study of one hundred and forty five cataract extractions showed a 38% incidence of post operative macular oedema. The leak had resolved in most cases by six months and the only factor of significance in the production of the oedema was preoperative hypertension. The likelihood of obtaining 6/6 vision postoperatively was much lessened in the presence of macular oedema.
