Purpose

To evaluate the outcomes of LASIK performed with a new generation solid state laser (AquariuZ). 

Setting

A retrospective, single-site, consecutive case series study. All patients received LASIK at the ORASIS Clinic and Swiss Eye Research Foundation in Reinach, Switzerland

Methods

32 myopic eyes with mean preoperative sphere of -1.95±1.77 diopters (D) (range: -0.25 to -7.50 D) and cylinder of -0.59±0.42 D (range: 0 to -2.00 D) underwent LASIK treatment using the AquariuZ solid state laser (Ziemer Ophthalmic Systems AG). Treatment centration was was performed by autodetection of Purkinje reflex before flap praparation. Safety and effectiveness outcomes as well as Manifest Refractive Spherical Equivalent (MRSE) were evaluated at 1-month follow up.

Results

No adverse events were reported. One month after surgery the CDVA remained unchanged for 25 eyes compared to preoperative visit, while 3 eyes lost 1 line and 4 eyes gained 1 line. Postoperative UDVA was 20/20 or better in 69% (22 eyes), 97% (31 eyes) reached UDVA 20/25 or better and all eyes reached UDVA of 20/40 or better. As for accuracy in MRSE, 72%  (23 eyes) reached target within ±0.25 D, 78 % (25 eyes) reached correction of ±0.50 D from target and 100%  (32 eyes) reached ±1.00 D.

Conclusions

LASIK with the AquariuZ solid state laser was shown to be a safe and effective procedure. The first clinical results achieved without an initial nomogram are encouraging. Further nomogram developments and studies with larger samples will underline the potential benefits of solid-state lasers, such as low susceptibility to corneal hydration, less thermal stress to tissue and fast healing processes.
