Advantages and disadvantages of different methods of senile cataract surgery.

Intra and extra capsular cataract surgery are discussed with regard to advantages and problems. Particular consideration is given to modern microsurgical extracapsular technique. Analysis of corneal complications, cystoid macular oedema and retinal detachment suggest that the present evidence does not justify a change to extracapsular technique, other than to give support to a posterior chamber intraocular lens. It is pointed out that for many surgeons, such a change of technique may cause more problems than it prevents.
