Before the posterior cataract surgery, the auxiliary examinations such as pupillary optometry, slit lamp microscopy, intraocular pressure measurement, AB ultrasound and OCT if necessary, should be perfected.
Before posterior cataract surgery, the first thing to do is to exclude and avoid the conditions that are not suitable for surgery. Improve the routine electrocardiogram examination and the assessment of the general state, if there is myocardial infarction and other life-threatening existence, first of all, we should save the life in time, to release the critical state, and then judge whether the surgery can be carried out depending on the situation after the release.
In addition to this, the ophthalmologic specialties such as optometry, corneal endothelium, slit lamp microscopy, intraocular pressure, AB ultrasound and OCT should be perfected in order to predict the effect of vision restoration after laser surgery, and priority should be given to resolving glaucoma and chronic lacrimal dacryocystitis in the presence of these problems.
It is recommended to choose cataract and posterior cataract surgery to regular hospitals, complete preoperative examination can be a certain guarantee of postoperative results and life health and safety.
