CLEAR Lenticule Extraction for Enhancement After Primary Lenticule Extraction Surgery.

Background

We aimed to evaluate the feasibility, safety, and efficiency of Corneal Lenticule Extraction for Advanced Refractive Correction (CLEAR) enhancement performed after primary CLEAR.

Methods

Six eyes from five patients underwent enhancement to correct residual myopic error. All procedures were carried out with the low-energy FEMTO LDV Z8 laser platform (Ziemer Ophthalmic Systems AG, Port, Switzerland) equipped with integrated optical coherence tomography enabling precise lenticule positioning.

Results

The myopic residual refractive sphere was fully corrected in all cases, with refraction remaining stable over the follow-up period. All eyes showed improvement in uncorrected distance visual acuity after retreatment with CLEAR and achieved 20/20 vision or better at the final follow-up visit.

Conclusions

Our results suggest that CLEAR enhancement is a safe and effective option for treating residual myopic refractive error after primary CLEAR, keeping the procedure flapless.
