Cataract Surgery Side Effects And What To Do

As with any surgical procedure, there can be some post-surgery side effects after cataract surgery that it’s important to be aware of. While some side effects are normal, it’s important to know how to manage them and when to contact your ophthalmologist.

In this blog, we’ll go through the common side effects that can occur after the procedure, how long they typically last, and what can be done to manage them. If you’re worried about any symptoms after your surgery, contacting your ophthalmologist is always a good idea to receive clarification on how to care for your eyes or discuss if further treatment may be necessary.

Normal post-treatment experiences: What to expect after cataract surgery

After cataract surgery, the eye will need time to heal, and vision may not be completely clear straight away. Some blurriness is normal in the early days, as the eye adjusts and inflammation reduces. It’s also common to experience mild discomfort, as well as sensitivity to light. We’ll go into these symptoms more later in the blog.

The first few weeks will involve following your ophthalmologist’s aftercare instructions, which will include using prescribed eye drops to help reduce inflammation and prevent infection. It’s important that you follow these instructions carefully, as this will support healing and help avoid complications.

In the early stages, it’s also best to avoid any activities that could put strain on the eye, such as heavy lifting or rubbing the area. Protective glasses may be recommended when outside to minimise exposure to bright light and prevent anything from getting into the eye while it’s still healing.

How to manage blurry vision after cataract surgery

Blurry vision is one of the most common temporary effects after cataract surgery. The extent of blurriness will vary, but most patients notice gradual improvement over the first few days to weeks.

Sometimes, your vision may also seem to fluctuate. This can happen as the brain adjusts to the removal of the cataract and the presence of the new intraocular lens. If both eyes are being treated separately, the difference in clarity between them can make this adjustment period more noticeable.

Using prescribed eye drops as directed and giving the eye enough time to heal will usually allow the vision to stabilise naturally. However, if the blurriness persists or worsens beyond your expected recovery period, we highly recommend contacting your ophthalmologist so that they can check for any underlying issues.

Managing light sensitivity and glare

Many patients will experience increased sensitivity to light in the first few weeks after cataract surgery. Bright lights, sunlight, or screens may feel more intense than usual, and some patients may notice halos or glare around lights, particularly at night.

Sensitivity to light happens because the eye is adjusting to the absence of the cataract, which previously filtered light in a way the brain had adapted to. With the new lens in place, the way light enters the eye changes, and it can take time for the brain to process this difference.

Wearing sunglasses when outdoors and avoiding overly bright environments can help in the short term. For most patients, light sensitivity will settle within a few weeks, but if it persists, your ophthalmologist may recommend additional measures to manage it.

Reducing dry eyes and irritation

A feeling of dryness, grittiness, or irritation in the eye is common after cataract surgery. This happens because the procedure can temporarily affect tear production, leading to dryness that can make the eye feel uncomfortable.

Lubricating eye drops, often called artificial tears, can help relieve this sensation and keep the eye hydrated. These are usually okay to use alongside prescribed post-operative drops, but it’s always best to check with your ophthalmologist before introducing anything new.

The dryness should gradually reduce over time as tear production normalises, but for some patients, it may take a little longer. If the discomfort continues, your ophthalmologist may recommend additional treatments.

Avoiding prolonged redness

It’s normal for the eye to look slightly red or bloodshot after surgery. This happens due to minor blood vessel irritation and usually clears up within a few days to weeks. Some patients may also experience mild itching or a sensation that there is something in the eye.

It’s important to avoid rubbing the eye, as this could worsen or prolong redness and irritation. If irritation becomes more noticeable or is accompanied by increased pain, swelling, or discharge, it’s important to contact your ophthalmologist, as this could indicate an infection or another issue requiring treatment.

Monitoring floaters (small floating shapes in your vision)

Some patients may notice an increase in floaters after cataract surgery. Floaters are small, shadowy shapes that move across the field of vision and are caused by tiny clumps within the vitreous, the gel-like substance inside the eye.

Most floaters are harmless and are simply more noticeable after surgery because of the change in vision. However, if there is a sudden increase in floaters, flashes of light, or a curtain-like shadow in the vision, this could indicate a more serious issue, such as retinal detachment. If this happens, urgent medical attention is required, so you should contact your ophthalmologist as soon as possible.

“Secondary cataracts” and long-term changes

After the procedure, some patients may develop a condition called posterior capsule opacification (PCO), often referred to as a “secondary cataract.” This is not a recurrence of the original cataract, but rather a thickening of the membrane that holds the artificial lens in place.

PCO can cause gradual blurriness months or even years after surgery, but it can be treated with a non-surgical laser procedure called YAG laser capsulotomy. This clears the cloudiness and restores vision without the need for another surgery.

In the long term, regular eye check-ups will help monitor any changes in vision. Some patients may need glasses for certain tasks, even if their vision has improved significantly after surgery, and prescription adjustments may be needed over time.
