Cataract surgery is a the most common eye surgery in all of ophthalmology. On the other hand, the prevalence of diabetes mellitus in the United States is very high at 14.7% of adults over the age of 18. Is cataract surgery safe for these diabetics? Patients with Type 2 Diabetes may be good candidates for this amazing procedure that can improve visual perception. Nonetheless, careful management of your disease by your health care provider is important to maximize your results.
Is cataract surgery safe for people with diabetes?
- In general, cataract surgery is safe for people with visual impairment and Type 2 Diabetes, especially if blood glucose is well-controlled.
- Advances in surgical techniques such as phacoemulsification, small-incision procedures, and advanced intraocular lens implants have made surgery quicker with a lower risk of complication.
- Nonetheless, if diabetes management is poor, then there may be a greater risk of worsening diabetic eye disease such as leaky blood vessels in the retina that can cause edema or swelling. Other risks of hyperglycemia include delayed wound healing and a higher risk of infection of the human eye (also known as endophthalmitis).
- Strict blood sugar control in the perioperative period is critical to reducing the likelihood of these potential complications.
How does diabetes affect cataract development and treatment?
Cataracts are an age-related clouding of the natural lens material inside of the human eye. But high blood sugar levels associated with diabetes can significantly increase a person’s risk of developing cataracts.
- Diabetics may develop cataracts earlier in life, i.e. at a younger age. The eye’s natural lens is typically composed of protein and is enveloped by thin layer of cells known as the capsule. These anatomical locations are very susceptible to blood sugar fluctuations that occur in diabetics, and the end result is cataract formation.
- Diabetic retinopathy is a complication of diabetes where damaged retinal blood vessels can cause bleeding in the retina and fluid accumulation in area known as the macula. All of these diabetic complications can cause the symptoms of blurred vision. Furthermore, these diabetic complications may be worsened by cataract surgery.
- If you have cataracts and coexisting diabetic eye disease, then you may need to visit your retina specialist to arrange for anti-vegf (vascular endothelial growth factor) treatment or laser therapy to the retina in the perioperative period. These interventions may reduce your risk of macular edema or other diabetic eye pathology that may be worsened by cataract surgery.
What should diabetic patients do to prepare for cataract surgery?
Strict blood sugar control and management of any existing diabetic eye disease are the most important factors in preparing for cataract surgery.
- Diabetic patients must pay close attention to their glycated hemoglobin (also known as Hemoglobin A1C).
- Diabetic patients should coordinate care with a primary care physician or endocrinologist, as well as a retina specialist.
- Be prepared to make pre-operative and post-operative visits to your retina specialist in case there is a need for intravitreal administration of medications (i.e. administration of medication into the vitreous jelly inside the human eye). Your retina specialist may also safely treat the eye with a gentle laser called PRP (pan-retinal photocoagulation) that may reduce the proliferative blood vessel disease (neovascularization) that is commonly seen in patients with diabetic retinopathy.
- Your surgeon will likely prescribe you a topical steroid eye drop as well as a nonsteroidal anti-inflammatory drug to be used after your cataract surgery. Make sure you have these items available to you in preparation for your cataract procedure.
FAQ’s About Can I Get Cataract Surgery If I Have Diabetes
What are the risks of cataract surgery for someone with diabetes?
The increased risks for diabetic cataract patients (compared to other cataract patients) include delayed healing, macular edema, and/or a worsening of existing diabetic retinopathy. You will have a better idea of your particular risk profile during your comprehensive eye examination performed at your pre-operative evaluation.
Will my diabetes make recovery from cataract surgery more difficult?
Diabetes complications may affect wound healing which may lead to a slower improvement in visual acuity after cataract surgery. Having strict control of blood sugar and blood pressure during the perioperative period will accelerate your visual recovery. With modern cataract surgery and a collaborative approach from your physician, your ophthalmologist should be successful improving your vision.
Can I have cataract surgery if I also have diabetic retinopathy?
Diabetic retinopathy includes bleeding and leaking of blood vessels of the retina, vitreous hemorrhage, tractional retinal detachments, as well as diabetic macular edema. Diabetic patients tend to develop visually significant cataracts at some point in their lives. Patients who suffer from these diabetic complications may still safely undergo cataract surgery if the eye disease is stable and well managed. A team effort involving the primary care doctor, primary ophthalmologist, and retinal specialist is necessary to maximize the odds of success. With modern cataract surgery these patients often have improved vision after cataract surgery.
Does cataract surgery affect my blood sugar levels?
The cataract surgery itself typically does not impact your blood sugar levels. On the day of the procedure, an anesthesia specialist will be available to administer intravenous medications that will help reduce any anxiety you feel about the procedure. Typically, the anesthesiologist will also be able to keep your blood sugar levels from becoming too high with the help of insulin (if necessary).
How do I know if I’m a good candidate for cataract surgery with diabetes?
Your ophthalmologist will be able to assess the health of your eye from your cornea in the front of the eye, all the way to the optic nerve in the back of the eye. The signs and symptoms of cataracts include blurry vision and glare despite the usage of a pair of updated corrective lens or glasses. Your eye surgeon will be able to assess if your symptoms are arising from your cataracts or from other eye disease such as diabetic retinopathy or glaucoma. Your ophthalmologist may also perform an OCT (Optical coherence tomography) test in the office to confirm that the macula (center of the retina) does not have any signs of fluid leakage. This preoperative evaluation will determine if you are a good candidate for cataract surgery.
Are the outcomes of cataract surgery different for people with diabetes?
In general, diabetic patients who have uncomplicated cataract surgery enjoy the same benefits of cataract surgery as everyone else. Cataract surgery will generally improve quality of life by giving patients vision that is more clear.
Should I stop taking my diabetes medications before cataract surgery?
Surgeons will generally have you suspend your diabetes medication on the morning of your surgery. Patients undergoing cataract surgery must be on an empty stomach. If you were to take your diabetes medication on an empty stomach, your blood glucose levels may be too low. If it turns out that you have elevated blood sugar levels, then the anesthesiologist involved in your care may administer insulin to bring your blood sugar under control.
How soon can I return to normal activities after cataract surgery if I have diabetes?
The postoperative recovery after cataract surgery is usually rapid with very good visual outcomes. Diabetes patients can typically return to normal activities within a few days of cataract treatment.
Can cataract surgery worsen my diabetic eye problems?
If you have significant diabetic retinopathy, the cataract surgery could indeed potentially worsen your eye problems. Diabetic retinopathy progression has been seen in previous research. Nonetheless, with careful preoperative planning, an uncomplicated phacoemulsification cataract surgery, and ongoing diabetic retinopathy treatment with a retina specialist, you will most likely have a successful surgery.
Will I need special follow-up care after cataract surgery due to my diabetes?
Yes, you will need follow-up care in the form of post-operative eye exams after cataract surgery to assure that your eye is healing according to plan. Your eye surgeon will be assessing your eye for any signs of inflammation or infection. If there is evidence of inflammation, your ophthalmologist may choose to initiate a corticosteroid eye drop to accelerate your post-operative recovery.
