Pterygium surgery is a common procedure designed to treat a pterygium, which is a benign growth of tissue on the conjunctiva of the eye that can extend onto the cornea. This condition may cause discomfort and visual impairment, prompting patients to seek surgical intervention. Understanding the various surgical options available is crucial for patients considering this treatment. Below are the different types of pterygium surgery commonly performed.

1. Excision Surgery

The most traditional form of pterygium surgery is excision surgery, where the surgeon removes the pterygium along with a small portion of the underlying conjunctival tissue. This method is typically effective, but one of its main drawbacks is the potential for recurrence. To combat this, surgeons may apply adjunctive treatments, such as the application of a mitomycin C solution, which helps reduce the likelihood of pterygium regrowth.

2. Autologous Conjunctival Grafting

Another option is autologous conjunctival grafting, which can decrease the rate of recurrence associated with excision surgery. During this procedure, the surgeon removes the pterygium and replaces it with a graft obtained from another area of the patient’s own conjunctiva. This method not only promotes better healing but also enhances cosmetic outcomes by minimizing scar formation.

3. Amniotic Membrane Grafting

Amniotic membrane grafting is another innovative technique used in pterygium surgery. In this procedure, a thin layer of amniotic membrane is placed over the surgical site post-excision. The amniotic membrane possesses properties that promote healing and reduce inflammation. This method has been shown to significantly lower the risk of recurrence and improve patient comfort during recovery.

4. Scleral Patch Grafting

Scleral patch grafting involves the use of donor scleral tissue to cover the area from which the pterygium has been removed. This technique is particularly beneficial for larger pterygia, as it minimizes the risk of corneal exposure and promotes tissue regeneration. Scleral grafting has also been associated with lower rates of recurrence compared to traditional excision methods alone.

5. Phacoemulsification

In some cases, particularly when the pterygium is associated with cataracts, phacoemulsification may be performed alongside pterygium surgery. This technique involves the removal of the cataract using ultrasound waves while simultaneously addressing the pterygium. Combining these procedures can reduce the need for multiple surgeries and improve overall visual outcomes.
