Purpose

To evaluate the outcomes of hyperopic 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 in Reinach, Switzerland.

Methods

15 hyperopic eyes with mean preoperative sphere of +1.43±0.52 diopters (D) (range: +0.75 to +2.75 D) and cylinder of -0.72±0.85 D (range: 0 to -3.50 D) underwent LASIK treatment using the AquariuZ solid state laser (Ziemer Ophthalmic Systems AG). Treatment centration was performed by autodetection of Purkinje reflex before flap preparation. Safety and effectiveness outcomes as well as Manifest Refractive Spherical Equivalent (MRSE) were evaluated at 1- and 3-month follow up. All eyes received plano target and no nomogram was applied.

Results

No adverse events were reported. At 1-month, CDVA remained unchanged for 11 eyes compared to preoperative visit, 4 eyes lost one line. At 3-months of 8 eyes, 1 eye gained one line of CDVA, 7 remained unchanged, no lines of CDVA were lost. Postoperative UDVA at 1-month was 20/20 or better in 6 eyes, 12 eyes reached UDVA 20/25 or better and all 15 eyes reached UDVA of 20/32 or better. At 3 months postoperative UDVA was 20/20 or better in 2 eyes, 6 eyes reached UDVA 20/25 or better and all 8 eyes reached UDVA of 20/32 or better. As for accuracy in MRSE at 1-month, 9 eyes reached ±0.25 D, 13 eyes reached ±0.50 D and all 15 eyes reached ±1.00 D. At 3-months 6 eyes reached ±0.25, 7 eyes reached ±0.50 D and all 8 eyes reached ±1.00 D.

Conclusions

Hyperopic LASIK with the AquariuZ solid state laser was shown to be a safe and effective procedure. The first clinical results for hyperopia corrections achieved without an initial nomogram are promising. 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 dependence on ambient conditions, as well as gentle tissue interaction resulting in fast healing processes.
