Can a Pterygium Grow Back After Treatment or Eye Surgery?
A pterygium is a noncancerous growth of tissue that develops on the surface of the eye and may gradually extend toward the cornea. While treatment can relieve irritation and improve the eye’s appearance, patients may also want to know whether the growth can return after removal.
At Maehara Eye Surgery & Laser in Honolulu, Dr. Jeffrey Maehara is a fellowship-trained Anterior Segment-Glaucoma Specialist with extensive experience in corneal, cataract, glaucoma, and refractive procedures. His advanced training helps support careful evaluation of pterygium and other conditions affecting the front surface of the eye.
Knowing why recurrence can occur is an important part of considering pterygium treatment.
Can a Pterygium Return After Surgery?
Yes. A pterygium can grow back after surgical removal, although recurrence is not inevitable. The likelihood of regrowth can depend on the surgical approach, the individual healing response, and continued exposure to environmental irritants.
Recurrent tissue may sometimes grow more aggressively than the original pterygium, making follow-up care particularly important after surgery.
What May Increase the Risk of Recurrence?
Several factors may influence whether a pterygium returns, including:
- Frequent exposure to ultraviolet light
- Wind, dust, and other environmental irritants
- Ongoing inflammation of the eye surface
- Individual healing characteristics
- The technique used during pterygium removal
Hawaii’s sunny climate makes ultraviolet protection especially important for patients in Honolulu and throughout the Islands.
How Is Pterygium Treatment Performed?
Not every pterygium requires surgery. Mild cases may be monitored and managed with lubricating or anti-inflammatory eye drops when appropriate.
Surgical treatment may be considered when a pterygium causes persistent irritation, affects vision, grows toward the center of the cornea, or creates significant cosmetic concerns. Modern surgical techniques may include covering the area where the growth was removed with healthy tissue to help reduce the chance of recurrence.
Can Patients Help Reduce Regrowth?
After treatment, following postoperative instructions and attending scheduled eye examinations can help support proper healing. Patients may also be advised to protect their eyes from UV exposure with quality sunglasses and, when possible, reduce exposure to wind, dust, and dryness.
Evaluate any new redness, irritation, or visible tissue growth rather than ignoring it.
