Summary
Femtosecond laser retreatment using only a side cut effectively corrects residual refractive errors after LASIK surgery. This method improved uncorrected distance visual acuity (UDVA) without complications in all treated eyes.
Area of Science:
- Ophthalmology
- Refractive Surgery
Background:
- Laser-assisted in situ keratomileusis (LASIK) is a common procedure for correcting refractive errors.
- Residual refractive errors can occur post-LASIK, necessitating retreatment.
- Femtosecond lasers offer advanced precision in corneal flap creation and tissue modification.
Purpose of the Study:
- To evaluate the visual and refractive outcomes of femtosecond laser retreatment in patients with prior LASIK.
- To assess the efficacy of flap lifting using only side cutting for retreatment.
Main Methods:
- Eleven eyes of seven patients with residual refractive error after primary LASIK underwent retreatment.
- A femtosecond laser was used to create a side cut for flap lifting.
- Primary LASIK treatment utilized side cutting only.
Main Results:
- Mean follow-up was 7.72 months post-retreatment.
- No intraoperative or postoperative complications were observed.
- Uncorrected distance visual acuity (UDVA) significantly improved from 0.54 preoperatively to 0.99 post-retreatment.
- No patient experienced a loss of corrected distance visual acuity.
Conclusions:
- Femtosecond laser retreatment with side-cut flap lifting is a safe and effective option for residual refractive errors post-LASIK.
- This approach can significantly enhance visual acuity in previously treated patients.
