What type of diabetes causes cataracts?
The type of cataract seen in diabetic patients has also been investigated. The most common is the senile type. However, snowflake cataracts, which are characteristic for DM, are very common in type 1 diabetics. Posterior subcapsular cataracts have also been shown to be significantly associated with diabetes.
What should be the sugar level for cataract operation?
Therefore, if the patient has hyperglycaemia on the day of surgery, but has had ′good′ long-term glycaemic control (i.e. an HbA1c that is age appropriate and not associated with increased perioperative harm, usually <8.5% (69 mmol/mol), or a preprandial blood glucose concentration of 108-180 mg/dl (6.0-10.0 mmol L−1).
What is the best time to have cataract surgery?
However, if an individual has blurred vision that makes it difficult to read print or read signs while driving; has disabling glare while driving at night; or has difficulty engaging in hobbies such as knitting, crocheting, or card games, it is time to consider cataract surgery.
How to treat diabetes in patients with cataract surgery?
Put in place specific, identifiable personnel as a point of contact for patients. This will minimise the loss of patients at postoperative and subsequent follow-up visits. There have always been questions about optimum blood sugar control for patients with diabetes prior to cataract surgery.
Can a diabetic have a pars plana cataract surgery?
In some cases, intravitreal injections of triamcinolone or anti-VEGF medications are given at the time of cataract surgery. For diabetics with non-clearing vitreous hemorrhages or tractional retinal detachments, cataract surgery can be combined with a pars plana vitrectomy in a teamwork approach with a vitreoretinal colleague.
Can a person with diabetic retinopathy have cataract?
People who are young and have both diabetes and cataract may have neglected their blood sugar control over the years or may not have had access to facilities to enable them to achieve good control. If blood sugar is not controlled, it will be very difficult to prevent vision loss to diabetic retinopathy.
What should you do before or after cataract surgery?
If macular edema (swelling in the central part of retina) is present, then it is mandatory to treat macular edema before cataract surgery. After treatment of macular edema cataract surgery operation should be planned. Depending on the stage of the diabetic retinopathy retina laser treatment may also be required.
