Purpose
To study the visual and refractive results of hyperopia and compound hyperopic astigmatism treated with LASIK using the wavefront Bausch & Lomb (B&L) Zyoptix platform and flaps created with the femtosecond IntraLase laser
ASCRS Symposium 2009, San Francisco, April 3-8,

Methods 1
Hyperopic patients undergoing wavefront LASIK with the B&L Zyoptix platform were studied prospectively
Flaps were created with the femtosecond IntraLase laser
Data were collected at months 1, 2, 3, 6 and at the time of discharge
ASCRS Symposium 2009, San Francisco, April 3-8,

4. ASCRS Symposium 2009, San Francisco, April 3-8,
Methods 2
Studied parameters were uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), manifest refraction as well as safety, efficacy and predictability
Only eyes with preoperative manifest spherical equivalent (MSE) of ≤+4.00 dioptres (D), BCVA of ≥20/20 and target refraction of emmetropia were included in this study
Results at the time of discharge are presented below as mean ± standard deviation and range

Conclusions
Wavefront guided LASIK for hyperopia and compound hyperopic astigmatism with the Zyoptix Bausch & Lomb platform and flaps created with the IntraLase femtosecond laser is
Highly effective
Very safe refractive procedure
It yields very accurate visual and refractive results
