Purpose The aim was to investigate the effect of ablation depth on the incidence and severity of the dry eye after laser-assisted in-situ keratomileusis (LASIK) treatment of myopia.
Patients and methods This was a prospective, noncomparative, interventional case series study that included myopic patients who underwent LASIK treatment for myopia ranging from −1.75 to −12.00 D. All patients had a comprehensive preoperative ophthalmologic evaluation. Tear breakup time (TBUT) and Schirmer 1 tests were undertaken for all patients preoperatively and at 1, 3, and 6 months postoperatively. The main outcome measures included the incidence and severity of the dry eye and their correlation with ablation depth at 1, 3, and 6 months postoperatively.
Results 104 eyes of 53 myopic patients (14 males and 39 females) with a mean age of 27.4±6.06 years (range: 21–45 years). At the baseline, the mean spherical equivalent was −6.38±2.82 D (range: −1.5 to −12 D), mean TBUT was 12.93±1.60 s (range: 10–17 s), and the mean Schirmer 1 score was 17.9±62.52 mm (range: 14–30 mm). Mean post-LASIK TBUT was 7.58±4.32, 10.22±5.38, and 12.07±4.02 s at 1, 3, and 6 months, respectively (P<0.001). The mean post-LASIK Schirmer 1 score was 8.50±5.01, 11.4±5.54, and 14.24±3.77 mm at 1, 3, and 6 months, respectively (P<0.001). There was a strong negative correlation between ablation depth and both TBUT and Schirmer 1 values at 1 and 3 follow-up months, but a moderate negative correlation at 6 months.
Conclusions There was moderate to strong negative correlation between ablation depth and the degree of post myopic LASIK dryness assessed objectively by TBUT and Schirmer 1 tests.
