Edema in the eye after cataract surgery

Cataract is a common eye disease that involves clouding of the eye's lens, and the main treatment is surgery, but it can cause edema in the eye that may impair vision. Treatment of the edema may be based on steroid drops and take several months.

Cataract in the eye is a condition characterized by clouding of the eye's lens. Cataract is a common eye disease, mainly at later ages, but it can develop for various reasons. Today, the main way of treating cataract is surgery to remove it. For the most part, patients who undergo surgery to remove a cataract gain a significant improvement in the quality of vision without long-term side effects.

However, this is an invasive procedure in the eye that is not free of complications, one of which is the development of edema in the eye after cataract surgery. In fact, edema in the eye develops when the blood vessels in it leak and the fluid accumulates in the various spaces. The accumulation of fluid causes edema in the eye and blurred vision.

Edema in the eye after cataract surgery can appear due to a wide variety of causes, but it can also develop without a visible cause. Nevertheless, it is more common among patients who have undergone previous eye surgeries, in diabetic patients and in patients with additional eye diseases. The edema can appear at different times after the surgery – it may appear very close to the surgery or even years after it. For the most part, edema in the eye after cataract surgery develops several weeks after the surgery.

Those suffering from edema in the eye after cataract surgery may often feel central blurred vision, while peripheral vision is usually preserved as normal. Among other things, one can expect distortion in vision or dim vision. Beyond that, the eye may be red, itchy and produce a lot of tears. In rare cases that are not treated, the edema may damage the eye irreversibly, even to the point of blindness.

The diagnosis of edema in the eye after cataract surgery should be made close to the appearance of the signs, by the operating physician. Diagnosing the condition is important because, in fact, there are two main types of edema in the eye after cataract surgery:

The first of them is macular edema. This is the most common complication after cataract surgery. Macular edema can develop up to about eight weeks after the surgery. The treatment of macular edema is usually based on steroid drops and lasts several months.

The second of them is edema in the cornea of the eye. After the surgery, the cornea may swell and become cloudy and thus cause blurred vision. Usually, edema in the cornea of the eye passes within days to weeks after the surgery. Edema in the eye after cataract surgery can be treated with steroids that will reduce the degree of swelling in the eye.

As noted, a small percentage of patients who undergo surgery to remove a cataract develop edema in the eye afterward. This is a complication that causes a decrease in the quality of vision and discomfort in the eye. The phenomenon of edema in the eye after cataract surgery can be treated with anti-inflammatory drug treatment and, in certain cases, with an additional surgery.
