Purpose

Comparison of clinical performance and visual outcomes of Keratorefractive Lenticule Extraction Using the Zeimer FEMTO LDV Z8 (CLEAR) versus Small-Incision Lenticule Extraction (SMILE Pro) using the Visumax 800.

Setting

Nethradhama Super Speciality Eye Hospital, Bangalore, Karnataka, India

Methods

A prospective, randomized, interventional study comparing two keratorefractive procedures – Keratorefractive Lenticule Extraction Using the Zeimer FEMTO LDV Z8 (CLEAR) versus Small-Incision Lenticule Extraction (SMILE Pro) using the Visumax 800. Each group had 40 patients and 80 eyes, all of whom were tested preoperatively and postoperatively on days 1, 15 and 3 months for manifest refraction, refractive spherical equivalent, Uncorrected Distance Visual Acuity (UDVA), Corrected Distance Visual Acuity (CDVA) and Optical Scatter Index (OSI) using HD-Analyser (HDA). 

Results

It was found that UDVA and CDVA was significantly better in the Visumax 800 group as compared to the Zeimer group at all postoperative visits (p<0.001). OSI was also significantly better in the Visumax 800 group as compared to the Zeimer group at all postoperative visits (p<0.001). 100% of patients in the Visumax 800 group achieved UDVA of 20/20 or better as compared to 93.8% in the Zeimer group. 

Conclusions

These initial results comparing femtosecond refractive laser platforms suggest that the Visumax 800 has shown comparably better outcomes with respect to UDVA, OSI and refractive accuracy.
