Purpose
To asses Post-Lasik refractive results in a population of topographic normal eyes with central corneal thickness (CCT) under 540μm, in order to co-relate post operative visual acuity and CCT.
Methods
Retrospective, observational case series. Records of hispanic patients undergoing refractive surgery at the Cornea and Refractive Surgery Service at the Ophthalomology and Visual Sciences Medical Center Zambrano Helion Institute from January 2012 to January 2014 were evaluated. Patients with preoperative CCT <540μm using Orbscan (Bausch & Lomb) and LASIK surgery were assesed, recording preoperative and post operative visual acuity for further analisis.
Results
Mean CCT was 513±65μm with no relationship in age and gender. Uncorrected distance visual acuity (UDVA) before surgery varied from 20/20 to CD 3ft. Nineteen patients (20%) had a postoperative UDVA of 20/400 and 17 (17%) had 20/200. Post operative acuity test results were mostly 20/20 with 76%, 20/15 with 13%. 76% of the patients had a post operative UDVA of 20/20 vision or better.
Conclusions
The CCT has no negative impact on the postoperative visual outcomes in patients undergoing LASIK surgery. Results suggest CCT should not be considered a determinant factor during the screening for candidates for ablative excimer laser surgery.
