Evaluation Of A New Femtosecond Laser For Lenticular Extraction

This study was conducted in 2 sites in India and Turkey.

This prospective study was conducted following ethics committee approvals and was registered in the CTRI database (CTRI/2020/07/026735).  Twenty myopic subjects were treated with the Next Gen Femto for Laser Assisted Lenticular Extraction.  Refractive and visual outcomes were assessed up to 6 months following surgery.  Safety of lenticule extraction surgery with the new laser was assessed.

Twenty eyes underwent lenticular extraction. Study eyes had spherical refractive error ranging from -7.00 to -2.00 D with cylinder refraction less than 0.5 D. At 6 months following treatment, mean MRSE was -0.4868 D and mean UCDVA was 0.037 (logMAR).  Mean change in BCDVA at Month 6 was -0.021 logMAR and maximum change in BCDVA (loss) was 0.08 logMAR. No lens opacification or disruption in the retinal layers were observed postoperative.  No laser related safety concerns were identified in the study.

The preliminary assessment of the performance of the new Next Gen Femto laser to correct spherical myopia suggests predictable refractive outcomes with stable results through 6 months. No unanticipated risks with the procedure were identified.
