To investigate the effect of patient’s age on the clinical outcome of LASIK refractive surgery.
A study was conducted with 657 eyes having low and moderate myopia, high myopia, hyperopia, and mixed astigmatism. Manifest refractions of the 6-month postOp were completed with all eyes in the study. Manifest refractions from the clinical outcome were adjusted to optical infinity. Wavefront refractions of the 6-month postOp were calculated for 485 eyes with wavefront measurements available over a 4 mm pupil. Chromatic aberration was corrected in the calculation of wavefront refraction. The 6-month postOp manifest spherical equivalent (MRSE) and wavefront spherical equivalent (WRSE) were correlated with the patient age.
In the 6-month postOp MRSE analysis, patients were in the age ranges 21 to 66 years old with distribution of 39.3±10.5. On average for the 657 eyes, the MRSE at the 6-month postOp was -0.30±0.50D. Some effects due to age were observed in the 6-month postOp MRSE with a trend of under corrections in young patients and over corrections in older patients, shown on the left in Figure1. In the 6-month postOp WRSE analysis, patients were in the age ranges 21 to 66 years old with distribution of 39.89±10.18. On average for the 485 eyes, the WRSE at the 6-month postOp is -0.59±0.74D. The 6-month postOp WRSE shows similar trend with age of under corrections in young patients and over corrections in older patients, shown on the right in Figure1.
Age has some influence on clinical outcome in laser vision correction. The trend is present but rather weak both from the postOp manifest refractions and the postOp wavefront refractions. Although age has not been used as a factor in the treatment design for refractive surgery, there is some evidence that patient’s age has an influence on the clinical outcome of refractive surgery.
