Summary:
Cataracts and glaucoma often occur together in older adults, making treatment planning more complex. While cataract surgery is generally safe even with high eye pressure, careful evaluation is essential. This blog explains how cataracts and glaucoma affect vision, whether cataract surgery lowers eye pressure, and when combined glaucoma and cataract surgery may be recommended. With a personalised approach and expert care, cataracts and glaucoma combination procedures can help patients achieve safer and more effective long-term outcomes.

Cataracts and glaucoma are two of the most common eye conditions, often occurring together in older adults. Managing these conditions simultaneously can be challenging, especially when considering surgical intervention. Patients frequently ask, “Can you have cataract surgery with high eye pressure?” The answer is yes, but it requires careful evaluation and planning.
First, let’s understand a little more about both the conditions.
Understanding Cataracts and Glaucoma
Cataracts develop when the eye’s natural lens becomes cloudy, impairing vision. This condition is treated through cataract eye surgery, where the cloudy lens is removed and replaced with an artificial lens.
Glaucoma, on the other hand, is a group of eye conditions that damage the optic nerve, often due to increased intraocular pressure (IOP). Left untreated, glaucoma can lead to irreversible vision loss. Eye surgery for glaucoma is often necessary when medications and other treatments fail to control high eye pressure.
Undergoing Cataract Surgery When Glaucoma Is Present
Yes, patients with glaucoma can safely undergo cataract surgery if the condition is properly managed. In many cases, cataract removal may even help lower IOP.
However, several factors must be considered:
- Severity of Glaucoma: Advanced glaucoma requires extra caution to avoid putting stress on the optic nerve during and after surgery.
- Eye Pressure Levels: High IOP must be stabilised before surgery to reduce complications.
- Combination Procedures: For many patients, doctors recommend combined glaucoma and cataract surgery. These cataracts and glaucoma combination procedures help manage both conditions at once and reduce the need for multiple surgeries.
Does Cataract Surgery Lower Eye Pressure?
Yes, cataract eye surgery has been shown to reduce IOP in many patients. By removing the cloudy lens, the surgery can improve the flow of aqueous humour (fluid inside the eye), thereby lowering pressure. This effect is more pronounced in patients with narrow-angle glaucoma. In patients with open-angle glaucoma, the reduction in pressure is less dramatic, but it can still help stabilise the condition.
However, it is essential to note that cataract surgery alone is not a cure for glaucoma, and additional treatments may still be necessary.
In conclusion, when glaucoma coexists with cataracts, combining glaucoma surgery with cataract surgery is often a viable option because this approach addresses both conditions simultaneously, reducing the need for multiple procedures.
Benefits of Combined Surgery for Cataracts and Glaucoma
Combining cataract eye surgery with glaucoma treatment offers several advantages:
- Improved Vision: Cataract removal enhances visual clarity, while glaucoma surgery preserves optic nerve health.
- Lower Eye Pressure: Procedures like trabeculectomy or the insertion of an eye stent can significantly reduce IOP.
- Fewer Procedures: A single combined surgery reduces the risks and inconvenience associated with undergoing multiple surgeries.
- Better Long-Term Outcomes: Managing both conditions together can lead to better control of glaucoma progression.
Complications of Cataract Surgery with Glaucoma
While generally safe, combining cataract surgery with glaucoma treatment can increase procedural complexity. Possible risks include:
-
Temporary IOP Spikes: A short-term pressure rise may occur after surgery.
-
Increased Inflammation: Glaucoma patients may require additional anti-inflammatory care.
-
Optic Nerve Sensitivity: Patients with advanced disease may experience nerve stress.
-
Longer Recovery: Healing can take more time when both issues are treated simultaneously.
A personalised pre-surgery evaluation helps minimise these risks.
How to Prepare for Surgery?
If you’re considering cataract eye surgery while managing glaucoma, here’s how to prepare:
- Consult a Specialist: Choose an experienced Specialist familiar with managing cataracts and glaucoma together.
- Control Eye Pressure: Stabilise your IOP before surgery using medications or laser treatments.
- Discuss Combination Options: Ask whether cataracts and glaucoma combination procedures—such as eye stent placement—are suitable for you.
- Follow Pre-Surgery Instructions: Adhere to medical advice, including adjusting medications if needed.
Once the surgery is done, recovery after combined cataract and glaucoma operation requires careful monitoring. Use all prescribed medications to manage inflammation and control eye pressure, attend scheduled follow-up appointments to track healing, and protect your eyes by avoiding strenuous activities or anything that may cause injury.
Post-Surgery Care
Recovery from combined cataract and glaucoma surgery requires close monitoring:
- Medication Adherence: Use prescribed eye drops to prevent infection, reduce inflammation, and control IOP.
- Follow-Up Appointments: Regular check-ups are crucial to monitor healing and assess the success of the procedure.
- Protect Your Eyes: Avoid strenuous activities and protect your eyes from injury during recovery.
Conclusion
When cataracts and glaucoma occur together, early evaluation and well-planned treatment are essential for protecting vision. Cataract surgery can safely be performed even with high eye pressure, and combined glaucoma and cataract surgery offers many patients the advantage of clearer vision and better long-term eye pressure control. With personalised planning and expert care, the risks can be minimised, and visual outcomes significantly improved. Take the first step toward healthier eyes.

FAQs
Yes, glaucoma can be treated with surgery, including procedures like trabeculectomy and minimally invasive techniques such as eye stent placement to lower IOP.
Potential complications include IOP spikes, inflammation, and prolonged recovery. Advanced glaucoma patients are at higher risk of optic nerve damage.
Having both glaucoma and cataracts can worsen vision, as cataracts cloud the lens and glaucoma damages the optic nerve. Proper management, often through combined surgery, can address both conditions effectively.
Yes, patients with glaucoma can safely undergo cataract eye surgery, often combined with a glaucoma procedure like an eye stent to manage high eye pressure.
Patients with uncontrolled eye infections, severe medical conditions, or advanced glaucoma with extensive optic nerve damage may not be ideal candidates for cataract surgery.
Recovery from combined surgery typically takes 4-6 weeks, though healing varies by individual. Regular follow-ups are essential to monitor eye pressure and ensure proper healing.
