Abstract Details

Purpose:

To compare recovery of the visual acuity in patients one day after SBK or LASIK.

Setting:

Excimer laser refractive center of Xijing hospital, the Fourth Military Medical University, Shaanxi, China.

Methods:

Data from 5923 eyes in 2513 patients that received LASIK (2755 eyes) or SBK (3168 eyes) were retrospectively analyzed. The eyes were divided into 4 groups according to preoperative spherical equivalent: between -12.00 to -9.00D, extremely high myopia; -9.00 to -6.00D, high myopia; -6.00 to -3.00D, moderate myopia; and -3.00 to 0.00D, low myopia. Uncorrected logMAR visual acuity values of patients were assessed under standard natural light. Analysis of variance was used for comparisons among different groups.

Results:

Uncorrected visual acuity values were 0.0115¡À0.1051 and 0.0466¡À0.1477 at day 1 after operation for patients receiving SBK and LASIK, respectively (P<0.01); visual acuity values of 0.1854¡À0.1842, 0.0615¡À0.1326, -0.0033¡À0.0978, and -0.0164¡À0.0972 were obtained for patients in the extremely high, high, moderate, and low myopia groups, respectively (P<0.01). In addition, significant differences in visual acuity at day 1 after operation were found between patients receiving SBK and LASIK in each myopia subgroup.

Conclusions:

Compared with LASIK, SBK is safer and more effective, with faster recovery. Therefore, SBK is more likely to be accepted by patients than LASIK for better uncorrected visual acuity the day following operation.
