Glaucoma and Cataracts: Planning Treatment Together
Glaucoma and cataracts are separate eye conditions, but many patients develop both as they get older. At our locations in Washington, D.C., Chevy Chase, and Tysons Corner, patients receive personalized care that considers how each condition affects their vision and long term eye health. Treatment may include prescription eye drops, Selective Laser Trabeculoplasty, cataract surgery, or Minimally Invasive Glaucoma Surgery.
Understanding how these treatments work together can help patients make informed decisions about protecting their vision.
How Glaucoma and Cataracts Differ
Glaucoma damages the optic nerve, often because of increased pressure inside the eye. The condition usually develops without noticeable symptoms. Any vision lost from glaucoma is permanent, so early detection and ongoing pressure control are essential.
A cataract occurs when the eye’s natural lens becomes cloudy. Cataracts may cause blurry vision, glare, faded colors, or difficulty driving at night. Unlike glaucoma related vision loss, vision affected by a cataract can often be improved by surgically replacing the cloudy lens.
When a patient has both conditions, the ophthalmologist must consider how treating one may affect the other.
Controlling Glaucoma Before Cataract Surgery
Some patients can manage glaucoma effectively with prescription eye drops. However, remembering every dose, administering the medication correctly, and managing multiple prescriptions can be challenging.
Selective Laser Trabeculoplasty, commonly called SLT, offers another way to control eye pressure. This office based laser procedure improves the eye’s natural drainage system, allowing fluid to leave the eye more efficiently.
Potential benefits of SLT include:
- No surgical incisions or stitches
- Minimal discomfort and recovery time
- Reduced reliance on medication for some patients
- The possibility of repeating treatment when appropriate
SLT may be considered as an initial treatment for certain patients with open angle glaucoma or ocular hypertension. It may also be recommended when eye drops are difficult to manage or are not lowering pressure sufficiently.
Addressing Glaucoma During Cataract Surgery
For eligible patients, cataract surgery may provide an opportunity to treat glaucoma at the same time. Minimally Invasive Glaucoma Surgery, or MIGS, includes several small incision procedures designed to improve eye pressure control.
Depending on the procedure, MIGS may:
- Improve the eye’s natural fluid drainage
- Create an additional drainage pathway
- Reduce resistance within the drainage system
- Decrease dependence on glaucoma medication for some patients
Combining MIGS with cataract surgery may allow the surgeon to address cloudy vision and elevated eye pressure during the same surgical experience.
However, MIGS is not appropriate for every patient. The recommendation depends on the type and severity of glaucoma, the target eye pressure, previous treatments, and the anatomy of the eye.
When Traditional Surgery May Be Needed
Patients with more advanced or complex glaucoma may need greater pressure reduction than MIGS can provide. In these cases, an ophthalmologist may recommend traditional glaucoma surgery or another procedure.
The goal is to select a treatment that lowers pressure enough to protect the optic nerve while considering the patient’s overall eye health and recovery needs.
Creating a Coordinated Treatment Plan
Glaucoma and cataract treatment should be planned around the individual patient. Your ophthalmologist will evaluate your eye pressure, optic nerve, peripheral vision, cataract symptoms, drainage system, and previous treatment results.
Your plan may include eye drops, SLT, cataract surgery, MIGS, traditional glaucoma surgery, or a combination of treatments. A coordinated approach can help improve vision affected by cataracts while protecting against further glaucoma damage. Call us today to book your exam.
