Abstract Details

Purpose:

To evaluate the efficacy, predictability and safety of LASIK retreatment based on manifest refraction in eyes with hyperopia and compound hyperopic astigmatism.

Setting:

University Hospital Hamburg-Eppendorf and Care Vision Germany.

Methods:

This retrospective study included hyperopic patients with a preoperative difference between cycloplegic and manifest refraction of 1.00 Diopter or less who had LASIK retreatment based on manifest refraction. The refractive outcome was analyzed according to standard graphs for reporting the efficacy, predictability, and safety of refractive surgery.

Results:

113 eyes of 113 consecutive hyperopic patients were enrolled. Efficacy after retreatment was statistically significant improved (P<0.001) without being negatively influenced by preoperative manifest spherical equivalent, manifest cylinder or keratometry. Still showing a trend towards undercorrection, retreatment resulted in 88 eyes (78.0%) that reached ±0.50 Diopter of the attempted correction. SI was statistically significant improved by retreatment (P=0.004) without being negatively influenced by preoperative manifest spherical equivalent, manifest cylinder or keratometry. The optical zone diameter did not correlate with efficacy, predictability or safety achieved by retreatment.

Conclusions:

Retreatment after hyperopic LASIK in eyes with a preoperative difference between cycloplegic and manifest refraction of 1.00 Diopter or less results in higher efficacy than the primary LASIK and higher predictability and safety when based on manifest refraction. Efficacy and safety of the retreatment are not influenced by preoperative manifest spherical equivalent, manifest cylinder, keratometry or optical zone diameter.
