Purpose

To evaluate changes in ocular wavefront measured values 3-months after myopic lenticule extraction on the

Schwind ATOS femtosecond platform and their relation to change in manifest refraction from the attempted myopic correction.

Setting

University Eye Clinic Svjetlot, Zagreb

Methods

Case series of 60 eyes undergoing uneventful SmartSight lenticule extraction all performed by the same

experienced surgeon (MB) was analyzed using the CSO Osiris-T (Schwind Peramis) Placido topography. Data were assessed for normality using the Shapiro-Wilk test.

Results

At 3M, the scattergram of achieved change in wavefront refraction vs. attempted refractive correction of the SEQ showed a very good correlation, with 68% eyes within 0.5D from target. The scattergram of achieved change in wavefront refraction vs. attempted refractive correction of the astigmatism showed only a fair correlation (Fig 3C), with 63% eyes within 0.5D from target. The angle of error was within 25deg from attempted astigmatism axis in 60% of the eyes.

Conclusions

Lenticule extraction treatment using SmartSight is safe and efficacious in the first 3-months postoperatively.

The post-operative outcomes indicate improvements in vision. There is a clear correlation between the ocular wavefront changes and the achieved refractive outcomes.
