Possible complications following cataract surgery

Here is an overview of the typical risks and complications associated with cataract surgery. Please note that individual risks can vary based on the unique characteristics of your eyes, and we will discuss your specific risks in detail during your cataract consultation.

General Complication Rate: The overall risk of complications from cataract surgery is around 2%. However, each patient’s risks may be different, so it’s important to pay attention during your consultation to understand if you have any specific risks that might be higher than average.

Retinal Detachment

There is a 1% risk of retinal detachment after cataract surgery. If this occurs, it can usually be repaired by a retina specialist with surgery, with a success rate of over 94%.

Retinal Swelling

Swelling of the retina can occur in about 1% of patients. This is typically treated with eye drops, but if the swelling persists, further treatment by a retina specialist may be necessary.

Lens Issues

The artificial intraocular lenses (IOLs) used in cataract surgery are generally safe and stable inside the eye. However, in less than 1% of cases, the lens may need to be repositioned, exchanged, or replaced. We use precise calculations to determine the optimal lens power to meet your visual goals, but it’s important to understand that we cannot guarantee perfect results. Some patients may end up more nearsighted, farsighted, or have more astigmatism after surgery. These conditions can usually be corrected with glasses, contact lenses, or additional procedures like IOL exchange or LASIK/PRK surgery.

Optical Side Effects

All IOLs carry the potential for optical side effects, such as glare, halos, or a flickering effect, particularly around the edges of your vision. These are common during the first few hours or days after surgery and typically resolve on their own. In rare cases, if symptoms persist, additional treatments or procedures may be needed to address these side effects.

Cataract Support Issues

In rare cases (less than 1 in 1,000 surgeries), the cataract may lack enough support during surgery and could fall into the back of the eye. If this happens, a retina specialist would need to perform additional surgery to complete the cataract removal.

Corneal Complications

The cornea may become swollen or cloudy after cataract surgery, but this typically resolves within one to two weeks. In less than 1 in 2,000 cases, the cloudiness may persist, requiring a corneal transplant to restore clear vision.

Serious Complications

The most serious, but rare, complications include infection, inflammation, or bleeding inside the eye. These occur in fewer than 1 in 3,500 surgeries and can lead to vision loss, though this is extremely uncommon.

Eyelid Drooping

In less than 1% of cases, patients may experience mild drooping of the upper eyelid after cataract surgery. If the eyelid drooping becomes problematic, a corrective procedure can be done about 3 to 4 months after the surgery.

While these complications are rare, it’s important to be fully informed about the potential risks. We will discuss your individual situation in detail during your consultation, and together we’ll create a plan that aligns with your specific needs and goals for the surgery.

  I was experiencing serious eye infection & I was able to get in to see Dr. SEMEL very quickly.  She diagnosed & prescribed meds, which are very quickly healing my eye.  The location has plenty of easy parking & the offices are very clean & well designed.  Pleasant staff also.

I had another appointment, different date with Dr. Julia Larson, OD, to check in on my MGD condition, and all was well, & the recommendations from the doctor had helped improve my situation.  She takes her time & is very through with the exam, while explaining in detail what condition I have.

She is very upbeat and a pleasure to have as my eye doctor.

  I usually receive compliments from people after I get Juvederm injections from Dr. Semel. The injections give my face a radiant and youthful look. Dr Semel has years of experience and education in applying Botox, Juvederm, and Voluma and her work always looks natural. I trust the quality of Dr. Semel’s work and always have confidence in what to expect from her.

I recently tried a new product from Dr. Jane Semel called SkinPen. One thing I really like about
Dr. Semel is that she always stays on top of new facial and neck products for women. SkinPen is the latest in technology to help the neck and face. It’s not an injection. Before the treatment, my face was gently cleansed. Then Dr. Semel used what looks like a pen and runs it over my neck and every area of my face which feels like a slight stinging that does not hurt. This treatment lasts about 30 minutes. It promotes a healing process of collagen and elastin that continues for months afterwards. My neck and face already look more youthful, softer and natural.

  Dr. Semel was professional, knowledgeable, and took the time to explain everything clearly. The staff was friendly, and I felt listened to throughout my visits for bilateral cataract eye surgeries. I would highly recommend this practice, if you want excellent medical care.
