Cataracts, which cloud the eye's natural lens, and glaucoma, characterized by increased intraocular pressure that damages the optic nerve, are two of the most common eye diseases, especially in older adults. It is not uncommon for patients to have both conditions simultaneously. When cataracts impair clear vision and medical or laser treatment fails to adequately control eye pressure, treating both conditions at the same time may be advisable. In this article, the specialists at Clínica Nivaria in Santa Cruz de Tenerife share several interesting facts.
Cataract and MIGS Surgery
Recently, less invasive glaucoma procedures with lower risks than traditional surgeries have been developed. These are known as MIGS, short for Minimally Invasive Glaucoma Surgery. These techniques can be performed in conjunction with cataract surgery in patients with mild to moderate open-angle glaucoma. Most of these surgeries use the same incision made to remove the cataract, allowing drainage of trapped fluid from the eye by removing or bypassing the obstruction with a small tube or stent. These procedures help lower intraocular pressure and, in some cases, reduce reliance on medication, although they do not always eliminate the need for all glaucoma treatments.
Reasons to choose MIGS during cataract surgery
- To reduce eye pressure, even if it is already low, seeking more effective long-term control.
- To minimize the amount of medication needed, since if the surgery is successful, the use of glaucoma eye drops could be reduced or even eliminated, which is a relief for many patients who find them difficult to apply.
When should you consider combined cataract and glaucoma surgery?
The decision is based on a thorough examination by one of our ophthalmologists in Santa Cruz de Tenerife, who will evaluate:
- The effectiveness of current glaucoma treatment in reducing eye pressure.
- Tolerance to side effects and the cost of glaucoma medications.
- The impact of cataracts on the patient's daily activities.
The goal is to offer the treatment that maximizes vision improvement with minimal risk.
Types of combined surgery
- Cataract surgery and trabeculectomy: Indicated for cases of severe or poorly controlled glaucoma, where the aim is to reduce eye pressure by creating a new drainage pathway.
- Cataract surgery and shunt procedures for glaucoma: A small tube is implanted to facilitate drainage of eye fluid, helping to reduce pressure.
Advantages of combined surgery:
- Convenience: A single surgical procedure is more practical and less stressful.
- Lower risk: The risk associated with anesthesia is reduced by half as only one intervention is required.
- Eye pressure stability: Glaucoma surgery prevents eye pressure spikes that can occur after cataract surgery.
- Cost reduction: The total cost is lower, and if the glaucoma surgery is successful, savings are made on medication.
Not all patients are ideal candidates for combined surgery. In some cases, the priority is to treat the glaucoma and postpone cataract surgery, while in others, the focus may be on resolving the cataracts first. Furthermore, in certain types of glaucoma, such as angle-closure glaucoma, cataract removal can improve eye pressure without the need for additional glaucoma surgery.
