Our Summary

This study looked at the frequency and results of surgery for glaucoma following cataract surgery in patients. It reviewed medical records of patients who had had a lensectomy (removal of the lens of the eye, usually to treat cataracts) at less than one year of age and were diagnosed with glaucoma.

Of the 127 patients studied, 73 (or 57%) had to have glaucoma surgery, with an average of two surgeries per patient. These surgeries typically occurred when the patient was about 3.5 years old.

The study found that the eyes which required glaucoma surgery had worse vision and more damage to the optic nerve (measured by the cup:disk ratio) at the final check-up. Also, patients who had a history of cataracts in both eyes had better vision in the affected eyes compared to those who had a history of cataracts in one eye.

Different surgical methods had varying success rates, with Baerveldt implants (a type of glaucoma drainage device) having the highest survival rates after 5 and 10 years.

In conclusion, more than half of the eyes with glaucoma following cataract surgery needed at least one glaucoma surgery. The need for glaucoma surgery and a history of cataracts in one eye were linked to worse vision outcomes.

Doctor’s Tip

One helpful tip a doctor might give a patient about glaucoma surgery is to closely follow post-operative care instructions to ensure the best possible outcome. This may include using prescribed eye drops, attending follow-up appointments, and avoiding activities that could increase eye pressure. Additionally, discussing the potential risks and benefits of different surgical methods with your doctor can help you make an informed decision about your treatment plan.

Suitable For

Patients who have undergone cataract surgery at a young age and are subsequently diagnosed with glaucoma are typically recommended glaucoma surgery if their condition does not respond well to other treatments such as medications or laser therapy. These patients may have more severe cases of glaucoma, with worse vision and optic nerve damage, making surgery a necessary option to prevent further vision loss and complications. Additionally, patients with a history of cataracts in both eyes may have better outcomes compared to those with cataracts in only one eye, suggesting that early intervention and treatment of both eyes may lead to better overall visual outcomes.

Timeline

Before glaucoma surgery:

  1. Patient undergoes cataract surgery to remove the lens of the eye.
  2. Patient is diagnosed with glaucoma, which may be a result of the cataract surgery or a separate condition.
  3. Patient may undergo various treatments to manage glaucoma, such as eye drops or laser therapy.

After glaucoma surgery:

  1. Patient undergoes glaucoma surgery, which may involve procedures such as trabeculectomy, glaucoma drainage devices, or laser trabeculoplasty.
  2. Patient may need multiple surgeries to effectively manage the glaucoma.
  3. Recovery process includes post-operative care and follow-up appointments to monitor the success of the surgery.
  4. Patient experiences improved intraocular pressure and vision outcomes, although some may still have residual vision loss or damage to the optic nerve.

  7. What is the expected outcome of glaucoma surgery in terms of preserving my vision and preventing further damage to the optic nerve?
  8. How often will I need follow-up appointments after glaucoma surgery?
  9. Are there any lifestyle changes or medications I will need to incorporate into my routine after glaucoma surgery?
  10. What are the long-term implications of having glaucoma surgery following cataract surgery?
