summary

My grandmother had cataract surgery the day before yesterday, and the surgery was very successful at that time. But today, the primary election focused on the phenomenon of corneal edema, and there are still some unclear phenomena. What are the causes of corneal edema after cataract surgery? Let me introduce it.

What are the causes of corneal edema after cataract surgery

The first reason is high intraocular pressure after cataract surgery, causing corneal epithelial edema and affecting your postoperative vision. This situation is relatively easy to deal with. Generally, hypertonic agents and hypotonic drugs can be used to control it in a few days, and the vision will recover.

Second, in cataract surgery, according to the patient's specific situation, specific treatment, the patient's lens nucleus is hard, phacoemulsification time is too long, or take small incision surgery, because the lens nucleus is large, in the extraction or removal of corneal endothelial damage, and cause postoperative corneal edema.

Third, once the anterior segment toxic syndrome occurs after cataract surgery, it indicates that the patient's condition is relatively serious, and it generally takes 3 ~ 6 months to recover. Appropriate treatment is needed.

matters needing attention

Avoid rubbing and colliding eyes after operation, limit violent activities within half a month, do not splash dirty water into eyes when bathing, shampooing and washing face; avoid violent exercise and weight-bearing within one month after operation, so as to avoid excessive force and high intraocular pressure causing surgical incision dehiscence.
