Although glasses and contact lenses are considered effective for early cataract symptoms, the only effective method to remove developing cataracts is to have them surgically removed. Cataract surgeries are frequently performed and in fact, considered safe and rarely trigger post-operative complications. However, in some cases, patients experience a couple of unexpected complications and among the most common ones is what-so-called as hazy or waxy vision which occurs after cataract surgical procedure.
Discomfort occurring after cataract surgeries
When you undergo a cataract surgery, your entire affected eye lens is removed and replaced with an artificial lens. Most people undergoing cataract surgeries experience minimal discomfort after the procedure. During the first days after the surgery, redness, discharge, and even feeling lens in eye are common complaints related to the performed surgery. Moreover, you might also notice a few black spots drifting through your vision, which makes it hard to focus your eye on objects easily and properly. As your treated eye needs a certain period of time to adjust itself with this newly-implanted lens, these discomfort is quite common to occur within days to weeks after surgeries.
Haziness after cataract surgeries
In cataract surgeries, the damaged eye lens is removed and replaced with an artificial lens. Thus, it is commonly normal for the eye to require a certain period of time for adjustment. Most people undergoing previous cataract surgeries are feeling lens in the eye after surgery, which triggers discomfort for several days to weeks. It is not questionable, since the eye does need a moment to settle down with the newly implanted lens from the surgery.
In line with this feeling lens sensation, hazy or waxy vision also tends to occur after a cataract surgery. This vision, though, should improve within days to weeks after surgery as the eye heals completely. Although this should not be a permanent complication following a cataract surgery, hazy vision may be complicated with the elderly or people with diabetes, for instance. There are some possible causes leading to haziness after cataract surgeries, which include:
- Altered shape of the cornea which is resulted from an extra capsular surgery. This shape alteration is going to cause temporary blurry vision after the surgery. In many cases, this problem goes away on its own, while in some others, it may require suture removal, which is a simple and painless procedure.
- Altered shape of the cornea may result in post-cataract astigmatism, which can possibly lead to either nearsightedness or farsightedness causing blurry vision. If this is what happens, corrective contact lenses or glasses can be used for help correcting the problem.
- The implanted lens may be multifocal, in which light sharing is inherent, inhibiting sufficient lighting in providing clear vision. It is possible because multifocal lenses mostly have aspheric model, which slightly differs from the retina’s natural spherical model. The use of well-prescribed glasses may also help correct blurry vision induced by this condition.
- Haziness may also occur long after the surgery because the clear implanted lens may haze and thus, lead to blurry vision. This is mostly related to aging and other problems, such as health complications and smoking habit that disturbs eye health.
More severe cataract surgery-related haziness
After cataract surgery, it is normal for haziness or blurriness of the vision to occur, considering the adjusting period required by the treated eye lens. Thus, this blurry vision should not last for more than two to four weeks after the surgery. Otherwise, you might require a thorough post-operative eye examination to determine the possible causes. If you are developing astigmatism after a cataract surgery, for instance, you will be able to have it corrected with glasses or contact lenses, so that it will not inhibit any daily activities, such as reading, writing, working on computer, and even watching television.
Although very rare, in very few cases, severe haziness that lasts long after a cataract surgery can be induced by a retinal detachment which may occur some years after cataract surgeries. This is a vision-threatening condition that may lead to vision loss. A retinal detachment can possibly happen when the retina is separated from the underlying layer of the eye.
