Is posterior cataract a good treatment?

summary

After extracapsular cataract extraction or lens trauma, if the disease is serious, it is necessary to carry out surgical treatment, and correct treatment of the disease. The residual cortex and epithelial cells falling off the posterior capsule of the lens proliferate and form a translucent membrane in the pupil area, which is called posterior cataract. With the popularization of aspiration, extracapsular surgery and phacoemulsification, posterior cataract is more common. Let's share with you about the good treatment of posterior cataract? Experience in this area.

Is posterior cataract a good treatment?

First, the proliferation and transformation of LEC under the anterior capsular and equatorial part of the anterior capsular polishing lens is the fundamental cause of PCO, so polishing the anterior capsular can reduce LEC to reduce the incidence of PCO. However, the study found that the decrease of LEC definitely reduced the incidence of anterior capsule opacification, but the impact on the incidence of PCO is still controversial.

Second: capsular tension ring (CTR) implantation. CTR was originally designed to support the capsular bag to maintain its shape and stability, visual acuity and refractive stability when the suspensory ligament was relaxed or even broken. CTR can play a role in reducing PCO, ACO and capsular fold in the early stage, but there is a lack of long-term and large sample follow-up study; In addition, CTR implantation can also prolong the operation time and increase the treatment cost to a certain extent.

Third: posterior capsulotomy combined with vitrectomy, which can significantly reduce the probability of PCO and YAG laser posterior capsulotomy, is mainly used for congenital cataract surgery. Although posterior capsulotomy combined with anterior vitrectomy for congenital cataract is generally considered to have a lower incidence of PCO than cataract surgery alone, it is easy to cause postoperative vitreous hyperplasia and traction in children, and its long-term impact on the posterior segment of the eyeball is controversial.

matters needing attention

Therefore, how to find simple, effective, economic, feasible and safe measures to prevent PCO is still worthy of our consideration.
