Abstract Details

Purpose:

The main aim of this study wasto compare efficacy, safety and predictability of femtosecond LASIK performed by two different platforms in the treatment of myopia.

Setting:

Hypervision Laser Centre, Athens, Greece Eye day Clinic, Athens, Greece Medical center Athens,Greece

Methods:

Myopic eyes had LASIK using the IntraLaseFS 60 kHzor the WaveLight FS 200 femtosecond laser system.Ablation was performed with the Visx Star S4 IR, or the WaveLight EX500 Excimer Laser respectively.Both groups were well matched for age, gender and mean level of preoperative refractive spherical equivalent (MRSE). Uncorrected visual acuity(UDVA), best spectacle-corrected distance visual acuity (BSCVA) and mean refractive spherical equivalent (MRSE)wereevaluated pre-operatively and at 1 week, 1 month and 6 months after treatment.

Results:

At 6 months post-op 78.6% of eyes in the 60 kHz and 92.9% in the FS200 group achieved an UDVA of 20/20 or better (p=0.252).35,7% and 50% in the 60 kHz group and the 200 FS group respectively gained 1 line, (p=0.179).No eye lost lines of CDVA. 25 eyes in the 60 KHZ(92.8%) and 27 eyes in the FS 200 Laser group (96.4%) had MRSE within ±0.5D (p>0.999).The mean efficacy index at six months was similar in both groups(mean1.10±0.12[SD] versus 1.10±0.1), (p=0.799). Mean safety index was similar (mean 1.10±0.10[SD] versus and 1.10±0.09 ),(p=0.407).

Conclusions:

Outcomes were excellent between the two femtosecond Laser platforms.There were no significant differences at 6 month between the two laser systems.
