What is the examination method of cataract disease
(1) Corneal endothelial cell examination: the cell density (CD) and the proportion of hexagonal cells were observed. When corneal endothelium is lower than 1000 / mm ~ 2, cataract surgery should be considered carefully to avoid postoperative corneal decompensation, which will affect the surgical effect and postoperative recovery.
(2) Retinal visual acuity test: project a specific image or visual target onto the retina, whether the refractive stroma is cloudy or not, directly check the visual acuity of the retina, in order to understand the best visual acuity of patients after surgery, which is an important method to evaluate the macular function before surgery.
(3) Visual field examination: for patients with light lens opacity and certain vision, visual field examination can find other diseases with cataract. For example, the central scotoma should be alert to the existence of macular lesions, the enlargement of physiological blind spot and the characteristic defect of visual field should be alert to the existence of glaucoma and other fundus lesions. Because cataract can also cause the change of visual field, it is necessary to identify the cloudy part of lens observed by slit lamp.
