Which condition is generally not a contraindication for refractive surgery?

Glaucoma is generally not considered a contraindication for refractive surgery because the procedure primarily focuses on correcting refractive errors such as myopia, hyperopia, and astigmatism, rather than directly affecting intraocular pressure or the structures affected by glaucoma. Patients with controlled glaucoma often undergo refractive surgery successfully, as long as their condition is stable, and they are under proper management.

In contrast, conditions like diabetes, severe dry eyes, and uncontrolled autoimmune diseases may pose greater risks during and after refractive surgery. Diabetes can lead to complications with wound healing and increased risk of infection. Severe dry eyes can significantly affect visual outcomes post-surgery, and uncontrolled autoimmune diseases may compromise healing and increase the risk of complications. Therefore, while glaucoma requires careful consideration, it does not inherently preclude a patient from being a candidate for refractive surgery the way the other conditions can.
