Study: LASIK in eyes with thin corneas safe, effective

In a study comparing LASIK outcomes in eyes with thin vs. thick corneas, Tomita and colleagues found that the procedure in the two groups resulted in comparable safety, efficacy and stability.

According to a study published in the Journal of Cataract and Refractive Surgery, the researchers evaluated 146 LASIK patients with thin corneas (central cornea thickness of less than 500 µm) and 193 LASIK patients with corneas of regular thickness, all with normal topography, up to 6 years postsurgically.

The researchers analyzed the two groups of patients for differences at the last check-up 3 to 4 years postoperatively, the abstract stated.

Both groups showed a significant difference in visual and refractive outcomes between the 3-month postoperative check and the most recent check, according to the study. However, no significant difference in visual, refractive or topography outcomes was seen. No postoperative complications occurred.

LASIK in eyes with thin corneas was as safe and effective as and showed similar long-term stability in eyes with a central cornea thickness of 500 μm or greater,” the authors concluded.
