What Happens If I Only Need One Eye Cataract Surgery?
Cataracts are a common eye condition that causes cloudiness, blurriness, and dullness of vision, often affecting your ability to see clearly. Cataract surgery is a highly effective treatment that involves replacing the cloudy natural lens with a clear artificial lens to restore vision.1https://www.aao.org/eye-health/diseases/what-is-cataract-surgery Millions of people worldwide undergo this surgery each year to improve their eyesight and, by extension, their quality of life.2https://www.who.int/news-room/fact-sheets/detail/blindness-and-visual-impairment
A common question people have is, ‘What happens if you only need cataract surgery in one eye?’ For example, do you need to have cataracts in both eyes to get the surgery? Will the surgeon work on both eyes in one sitting? (The short answer is no: cataract surgery usually focuses on one eye at a time.)

For now, let’s dive into answering some pressing questions about cataract surgery.
Can You Have a Cataract in Only One Eye?
Yes, it is possible to develop a cataract in only one eye. Although cataracts often occur in both eyes, they do not always develop at the same rate or time. Cataracts in one eye can be caused by specific factors such as trauma, eye surgery, or certain medical conditions. For instance, an injury to one eye can cause a cataract to form in that eye alone, while the other eye remains unaffected.
Certain medical conditions, such as diabetes, or prolonged use of steroid medications can also lead to the formation of cataracts in one eye.3https://www.mayoclinic.org/diseases-conditions/cataracts/symptoms-causes/syc-20353790 In some cases, previous eye surgeries or treatments, such as radiation therapy for cancer, may trigger cataract development in a single eye. Even lifestyle factors, such as excessive exposure to sunlight without proper eye protection, can contribute to cataract formation in one eye only.
Symptoms of Cataracts in One Eye
When only one eye is affected by a cataract, you may notice symptoms like blurry vision, difficulty judging distances, or a difference in the quality of vision between your two eyes. You might experience double vision in the affected eye or have trouble with depth perception, which can make daily tasks more challenging. Many people also find that they struggle with bright lights or experience increased glare, especially when driving at night.
Another symptom of a cataract in one eye is the phenomenon of monocular diplopia, which is when you see double images with just one eye open. This occurs because the cataract scatters incoming light, causing it to split into multiple images. You may also notice colours appearing duller or more yellowed in the affected eye, leading to an imbalance in colour perception between the two eyes.
If you have a cataract in only one eye, it can create an imbalance that makes it difficult for the eyes to work together properly. This can lead to eye strain, headaches, and a general sense of visual discomfort. Recognising these symptoms early and consulting with an ophthalmologist can help you determine the right course of action.
How Does Cataract Surgery Work?
Overview of the Cataract Surgery Procedure
Cataract surgery involves removing the cloudy lens from your eye and replacing it with an artificial lens called an intraocular lens (IOL). The procedure is typically performed under local anaesthetic, and you will be awake but comfortable during the surgery. The surgeon makes a small incision in your eye, uses ultrasound waves to break up the cloudy lens, and then replaces it with the clear artificial lens.
The artificial lens, or IOL, is designed to focus light properly onto the retina, just like a natural lens would. There are different types of IOLs available, including monofocal lenses (which correct vision at one distance), multifocal lenses (which can correct vision at multiple distances), and toric lenses (which correct astigmatism). Your ophthalmologist will recommend the best type of IOL based on your individual needs and lifestyle.
What to Expect Before, During, and After Surgery
Before surgery, your ophthalmologist will perform a comprehensive eye examination to assess your eye health and determine the best type of lens for you. Measurements of your eye will be taken to ensure the correct power of the artificial lens is chosen. You will also be given specific instructions on how to prepare for surgery, which may include using certain eye drops and avoiding food or drink for a few hours before the procedure.
During the surgery, which usually takes about 20–30 minutes, you will be given eye drops to dilate your pupil and a local anaesthetic to numb the area. The small incision made by the surgeon allows for the insertion of a probe that emits ultrasound waves to break up the cloudy lens. These fragments are then gently suctioned out of the eye. The artificial lens is folded and inserted through the same incision, where it unfolds and is positioned correctly within the eye.
After surgery, you may experience mild discomfort, itching, or a gritty feeling in the eye. It is important not to rub your eye during this time. Your doctor will provide you with eye drops to prevent infection and reduce inflammation, as well as a protective shield to wear, particularly when sleeping, to avoid accidentally injuring the eye. Recovery is usually quick, and many people notice an improvement in their vision within a few days, although full recovery can take several weeks.
Do They Usually Perform Cataract Surgery on Both Eyes at Once?
Why Cataract Surgery Is Usually Done One Eye at a Time
Even if you have cataracts in both eyes, most ophthalmologists recommend performing cataract surgery on one eye at a time to reduce the risk of complications and allow the first eye to heal before operating on the second eye. This approach ensures that if any issues arise during the recovery of the first eye, they can be addressed before proceeding with surgery on the second eye. Typically, if both eyes need surgery, the second procedure is scheduled a few weeks after the first, once the initial eye has healed well.
Performing cataract surgery on one eye at a time also allows the patient to experience the improvement in vision in the treated eye before deciding on surgery for the other eye. This can be particularly reassuring for those who may feel anxious about undergoing the procedure. Additionally, it helps the ophthalmologist determine if any adjustments are needed for the second eye based on the outcome of the first surgery.
Exceptions to This Approach
In rare cases, both eyes may be operated on at the same time, particularly if the patient’s circumstances make it difficult to attend multiple surgeries. For example, patients with significant mobility issues or those who would face extreme hardship in attending separate appointments might be considered for bilateral cataract surgery. However, this is not common practice due to the increased risk of complications, such as infection or inflammation affecting both eyes simultaneously.
There are also situations where the urgency of vision correction in both eyes may lead to a discussion about simultaneous surgery. This decision would be made carefully, weighing the potential benefits against the increased risks. Your ophthalmologist will provide guidance based on your specific needs and health condition.
What Happens If You Only Need Cataract Surgery in One Eye?
Adjusting to Vision Imbalance
After having cataract surgery in one eye, you may notice an imbalance in your vision, especially if the untreated eye still has a cataract. Your brain will need time to adjust to the difference in clarity between the two eyes, but it generally adapts over time, and your vision should become more comfortable. However, during the adjustment period, you may experience symptoms such as eye strain, headaches, or difficulty with depth perception.
The adjustment process can vary from person to person. Some people adapt quickly, while others may need more time to get used to the difference in vision. It is important to give yourself time to adjust and to follow any recommendations from your eye care professional. If you find that the imbalance is causing significant discomfort, discuss potential solutions with your ophthalmologist.
Can Glasses or Contact Lenses Help?
Glasses or contact lenses can help balance your vision while you wait to see if the other eye requires surgery. Your eye care professional may recommend a specific prescription to help you adjust to the difference in vision between your two eyes. For example, a temporary pair of glasses with a prescription adjusted to account for the difference in clarity between the eyes can help reduce symptoms of imbalance.
In some cases, a temporary contact lens may be used to improve balance and make daily activities easier. Contact lenses can provide a more seamless correction compared to glasses, as they sit directly on the eye and reduce the distortion that can sometimes occur with glasses. Your eye care professional will help you determine the best option based on your comfort and needs.
Additionally, using multifocal or progressive lenses in your glasses can help you adapt to the difference in vision by providing a range of focus strengths. This can be particularly helpful for tasks like reading or working on a computer, where different focal distances are needed.
How Long Is the Recovery Time for Cataract Surgery?
Recovery Timeline for One Eye
Most people find that their vision improves significantly within a few days after cataract surgery, although complete healing can take up to four to six weeks. During the initial recovery period, you may experience some blurriness, light sensitivity, or a gritty feeling in the eye, which should improve as the eye heals. It is also common to see halos around lights, especially at night, but this usually diminishes as the eye continues to recover.
It is important to take care during the recovery period to avoid complications. Your doctor will provide specific instructions, such as avoiding swimming, hot tubs, and heavy lifting. You may also be advised to wear sunglasses when outdoors to protect your eyes from bright light and UV radiation. Following these guidelines will help ensure a smooth and successful recovery.
Tips for a Smooth Recovery
To ensure a smooth recovery, follow your doctor’s instructions carefully, use prescribed eye drops as directed, and avoid rubbing or pressing on your eye. Keeping your hands clean and avoiding any potential irritants is important during the healing process. Avoid heavy lifting, bending over, or any strenuous activity for at least a week after surgery to prevent increased pressure in the eye. Attend all follow-up appointments to ensure your eye is healing properly.
During recovery, it is also helpful to rest your eyes as much as possible. Avoid prolonged screen time, reading, or any activities that may cause eye strain. When watching television or using electronic devices, take frequent breaks to allow your eyes to rest. Maintaining a healthy diet rich in vitamins and antioxidants, such as leafy greens and fish, can also support your eye health and aid in recovery.
If you experience any unusual symptoms, such as severe pain, sudden vision loss, or signs of infection (such as redness, swelling, or discharge), contact your ophthalmologist immediately. Early intervention can prevent more serious complications and ensure the best possible outcome for your surgery.
What If You Develop a Cataract in the Other Eye Later?
Is It Likely to Develop Cataracts in the Second Eye?
Cataracts are often a bilateral condition, meaning that if you develop a cataract in one eye, it’s likely that the other eye will eventually develop one as well4https://www.nei.nih.gov/learn-about-eye-health/eye-conditions-and-diseases/cataracts. The timing of cataract development can vary, and regular eye exams are important to monitor any changes in the other eye. While some people may develop cataracts in both eyes simultaneously, others may have a significant gap in time between the development in each eye.
Factors such as age, underlying health conditions, and exposure to risk factors like UV light can influence the likelihood and timing of cataract development in the second eye. Regular eye check-ups are essential to detect changes early and determine the right time for treatment. Early intervention can help maintain good vision and reduce the impact of cataracts on your daily life.
How to Monitor the Health of Your Other Eye
Regular check-ups with your ophthalmologist are needed for monitoring the health of both eyes, especially if you have already had cataract surgery in one eye. During these visits, your doctor will perform tests to assess the clarity of your lens, measure your visual acuity, and check for any other eye health issues that may be developing. Early detection of a cataract in the second eye can help you plan for surgery at the right time to maintain the best possible vision.
In addition to regular check-ups, it is important to be aware of any changes in your vision. If you notice symptoms such as increased blurriness, difficulty with night vision, or increased sensitivity to light, contact your ophthalmologist. These could be signs that a cataract is developing in the second eye, and early assessment can lead to timely treatment.
Lifestyle changes can also help protect the health of your eyes and potentially delay the onset of cataracts. Wearing sunglasses that block 100% of UV rays, avoiding smoking, and managing health conditions like diabetes can all contribute to better eye health and reduce the risk of cataracts.
Frequently Asked Questions About Cataract Surgery in One Eye
Will I Need Reading Glasses After Cataract Surgery in One Eye?
Whether you will need reading glasses after surgery depends on the type of intraocular lens (IOL) used during your cataract surgery. Standard monofocal lenses correct distance vision, meaning you will likely need reading glasses for close-up tasks. Premium multifocal or accommodating lenses may reduce your need for glasses. However, these lenses may not be suitable for everyone, and your ophthalmologist will help you decide which option is best for your individual needs.
It is important to have realistic expectations regarding your vision after cataract surgery. While premium lenses can reduce your dependence on glasses, they may not eliminate the need entirely. Some patients find that they still need glasses for specific tasks, such as reading small print or working on a computer. Your ophthalmologist will discuss the pros and cons of each type of lens to help you make an informed decision.
What Are the Risks of Only Treating One Eye?
Treating only one eye can result in a temporary imbalance in vision, which may feel unusual until your brain adjusts. As with any surgery, there are potential risks such as infection, swelling, or complications with the artificial lens, but these risks are rare and can usually be managed effectively with prompt treatment. It is important to follow all post-operative care instructions to minimise the risk of complications.
One of the challenges of treating only one eye is the potential for anisometropia, a condition where there is a significant difference in the refractive power between the two eyes. This can lead to difficulty in achieving clear binocular vision, as the brain may struggle to merge the images from both eyes. In most cases, this imbalance can be managed with corrective lenses or contact lenses until the second eye is treated.
How to Decide If Cataract Surgery in One Eye Is Right for You
Consulting with an Ophthalmologist
It’s important to consult with an experienced ophthalmologist like Dan Nguyen to determine whether cataract surgery in one eye is the best option for you. A thorough eye examination will help assess the severity of the cataract and the potential benefits of surgery for your vision. Your ophthalmologist will also consider your overall health, lifestyle, and specific visual needs when making a recommendation.
During your consultation, you will have the opportunity to ask questions and discuss any concerns you may have about the procedure. Understanding the risks, benefits, and expected outcomes will help you make an informed decision. Your ophthalmologist may also discuss the potential for needing surgery in the other eye at a later date and how to best prepare for that possibility.
Weighing the Pros and Cons
When deciding whether to proceed with cataract surgery in one eye, consider factors such as the impact on your daily activities, the potential for improved vision, and the risks involved. Your ophthalmologist will help you weigh these considerations to make an informed decision that aligns with your needs and lifestyle. For many people, the benefits of improved vision and quality of life outweigh the risks associated with the surgery.
It is also important to consider how the cataract is affecting your ability to perform everyday tasks, such as reading, driving, or recognising faces. If the cataract is significantly impacting your quality of life, surgery may be the best option to restore your vision and independence. On the other hand, if the cataract is still in its early stages and not causing significant problems, your ophthalmologist may recommend monitoring it until surgery becomes necessary.
Conclusion
