Summary
Cycloplegic autorefractometry is reliable only for the axis after laser in situ keratomileusis (LASIK) eye surgery. Subjective refraction is essential for accurate vision correction and retreatment decisions following LASIK.
Area of Science:
- Ophthalmology
- Refractive Surgery
- Optometry
Background:
- Laser in situ keratomileusis (LASIK) is a common refractive surgery.
- Accurate refractive measurements are crucial for post-LASIK vision assessment.
Purpose of the Study:
- To compare cycloplegic subjective refraction with cycloplegic autorefractometry in eyes after LASIK.
- To evaluate the reliability of autorefractometry for post-LASIK refractive error assessment.
Main Methods:
- Subjective refraction and autorefractometry were performed under cycloplegia.
- Measurements were taken at 1, 6, and 12 months post-LASIK in 73 eyes.
- Preoperative measurements served as controls.
Main Results:
- Significant differences were found between subjective refraction and autorefraction for sphere and cylinder post-LASIK.
- No significant difference was observed for the axis in post-LASIK eyes.
- Control (preoperative) eyes showed no significant differences.
Conclusions:
- Cycloplegic autorefractometry is reliable only for the axis after LASIK.
- Subjective refraction is critical for guiding retreatment decisions post-LASIK.
