What is a common adverse effect of laser-assisted in situ keratomileusis (LASIK) surgery?

Dry eyes are a common adverse effect of laser-assisted in situ keratomileusis (LASIK) surgery. During the LASIK procedure, the corneal nerves that help in tear production can be temporarily disrupted. This reduction in sensation may lead to decreased tear secretion, resulting in dryness and discomfort in the eyes. Patients often report symptoms such as a gritty sensation, burning, or excessive tearing, which can affect their overall comfort and visual experience post-surgery.

While glare in bright light can occur after LASIK, it is usually temporary and may not be as prevalent as dry eyes, which are a more consistent and reported issue in the postoperative phase. Night blindness can also be a concern for some patients, but it is less common and not typically highlighted as a primary adverse effect associated with LASIK. Increased intraocular pressure is generally not a direct consequence of LASIK and is more related to other types of eye conditions or surgeries. Thus, dry eyes stand out as a significant and well-documented adverse effect of LASIK.
