How Long Should You Wait Between Cataract Surgery on Each Eye?
Cataract surgery is a very common and highly effective outpatient procedure that brings significant improvements to vision and quality of life for those dealing with cataracts. Now, if you have cataracts in both eyes, you might be wondering about the best time between surgeries and whether it’s better to tackle both eyes on the same day.
Generally, it’s advisable to wait until vision normalizes and the first eye fully heals before proceeding to the second eye. On average, this waiting period falls between one to six weeks.1 This guide is here to help you understand the factors that determine when to have cataract surgery on each eye, what the recovery process looks like, and important things to keep in mind for the best results.
Key Points
- Scheduling cataract surgeries one to six weeks apart is advisable to allow the first eye to fully heal and normalize vision.
- The type of intraocular lens chosen for the first eye plays a role in determining how long to wait between cataract surgeries on each eye.
- Temporary side effects like blurred vision and sensitivity to light are part of the cataract surgery recovery process.
What are Cataracts?
Cataracts are a clouding of the eye’s lens, causing vision issues that can impact your daily activities.1 Each eye has a natural lens that focuses light to create clear images on the retina. However, around age 40, proteins break down, forming cloudy areas called cataracts on the lens.2
Cataracts develop slowly, often without noticeable symptoms for years. Regular eye exams are important to preserve clear vision and monitor the development and progression of cataracts. If left untreated, cataracts can lead to vision loss2, but cataract surgery can reverse this condition and bring back your clear vision.1
Various risk factors contribute to cataract formation, including age, excessive sun exposure, smoking, heavy alcohol consumption, diabetes, eye injury or trauma, radiation treatment, eye surgery, and prolonged use of steroids.2
The good news is, a healthy diet and positive lifestyle changes can help delay and slow cataract development. Cataract surgery, a common procedure with a high success rate, restores vision for millions annually.3
Symptoms of Cataracts
Identifying the symptoms of cataracts is necessary for timely intervention. Common signs include:2
- blurred or hazy vision
- increased sensitivity to light
- difficulty seeing at night
- perception of faded colors
- halos around lights
If you experience any of these symptoms, consult with an eye doctor (optometrist or ophthalmologist) for a comprehensive eye exam to confirm the presence of cataracts and discuss potential treatment options.

Understanding Cataract Surgery
Cataract surgery involves carefully removing the cloudy natural lens and replacing it with an artificial lens known as an intraocular lens (IOL). The surgical procedure typically takes place on an outpatient basis, and advancements such as phacoemulsification have made it a minimally invasive and highly successful intervention.1
Bilateral cataract surgery is when both eyes undergo cataract removal and IOL implantation. Performing cataract surgery on each eye during separate surgeries is the most common approach.2
While same-day cataract surgery offers the advantage of a consolidated recovery period, it may not be appropriate for everyone. Engaging in a detailed discussion with your eye surgeon helps tailor the approach to your specific needs and circumstances.
Factors Influencing Timing of Second Eye Cataract Surgery
The recovery period post-cataract surgery is not just about regaining vision but ensuring your eye heals completely. While improvements may be noticeable within a day, allowing the first eye to stabilize ensures a more thorough recovery and sets the stage for the success of the second surgery.
The recovery time for cataract surgery is typically short, with many patients experiencing improved vision within a day. However, the complete healing of the eye may take a few weeks. Eye surgeons often advise waiting for the first eye to stabilize before proceeding with surgery on the second eye.
Regular eye exams are essential during the interim, especially for individuals at risk of eye diseases such as glaucoma or retinal issues. The interval between cataract surgeries allows the eye surgeon to monitor and address any pre-existing or emerging conditions.
Risk of Complications
While cataract surgery is considered a low-risk procedure, there is always a slight risk of complications. Waiting for the first eye to heal allows your eye surgeon to assess any potential issues and make adjustments to optimize the outcome of the second surgery.
Certain risk factors may increase the likelihood of complications. These factors include your age, pre-existing eye conditions such as glaucoma or retinal issues, systemic conditions like diabetes, and a history of eye trauma. Your eye surgeon will carefully assess these risk factors to develop a personalized surgical plan and mitigate potential complications.1

Choice of Intraocular Lenses
The type of IOL chosen for the first eye during cataract surgery may influence the timing of the second eye cataract surgery. If you opt for a monofocal IOL in the first eye, which typically corrects vision for either distance or near,1 your surgeon may consider a shorter interval between the surgeries. This is because the visual adjustment process might be smoother when the second eye is addressed relatively soon after the first.
On the other hand, if you choose a multifocal or accommodating IOL for the first eye, which aims to correct both distance and near vision,1 your ophthalmologist may suggest a slightly longer interval between the surgeries. This allows for a more accurate assessment of visual outcomes in the first eye before determining the optimal prescription for the second eye.
Patients with astigmatism may opt for additional procedures, such as limbal relaxing incisions or choose toric intraocular lenses, to correct astigmatism during cataract surgery.1 This choice will also factor into the timing of your cataract surgery on each eye.
What to Expect After Having Cataract Surgery
The benefits of cataract surgery are quite promising. This corrective procedure not only enhances your vision but can also reduce your risk of falls, make it easier to recognize your friends and loved ones, and more. According to research, about 9 out of 10 people see positive changes after the surgery.4
If you find yourself needing cataract surgery in both eyes in the same year, it’s a good idea to schedule them as close together as your eye doctor recommends.
Recovery Process
Following cataract surgery, patients are usually provided with eye drops to aid in the healing process and prevent infection. It’s essential to follow the prescribed medication regimen and attend any scheduled follow-up appointments with your eye surgeon. Additionally, protecting the eyes with an eye shield, especially during sleep, can prevent accidental rubbing or pressure on the operated eye.4
After cataract surgery, you may experience temporary side effects such as blurred vision, halos, or sensitivity to light.5 These effects are typically short-lived and diminish as the eye heals. Engaging in daily activities, including reading and watching television, is generally encouraged during the recovery period.
During the interim period between cataract surgeries, you may need to rely on contact lenses or eyeglasses to compensate for any differences in vision between your eyes.4

How Long Between Cataract Surgery on Each Eye FAQ
The timing for the second cataract surgery depends on factors such as the individual’s healing process and the surgeon’s recommendation. Typically, surgeons may advise waiting a few weeks to allow the first eye to heal adequately before scheduling the second surgery.
Yes, waiting a month between cataract surgeries is generally considered acceptable. This interval allows for proper healing of the first eye and ensures a smoother recovery process for the second eye. Your eye surgeon will provide personalized guidance based on your specific situation.
The second cataract surgery, like the first, is generally not painful during the procedure due to the use of anesthesia. Patients may experience mild discomfort or irritation afterward, but this is typically temporary. Pain management can be achieved with prescribed medications and adherence to post-operative care instructions provided by your eye surgeon.
Putting It All Together
Your journey to clearer vision with cataract surgery involves thoughtful decisions and collaboration with your eye care professionals. Recognizing that a healthy recovery often takes 2 to 6 weeks between surgeries, and understanding how factors like the type of IOL and the recovery process come into play, you’re well-prepared to make informed choices. With the guidance of your eye surgeon and a positive outlook, you’re moving towards a future filled with clearer vision and the joy it brings to your daily experiences.
