Purpose

• To study the visual and refractive results of
  hyperopia and compound hyperopic astigmatism
  treated with LASIK using the wavefront Bausch
  Lomb (BL) Zyoptix platform and flaps created
  with the femtosecond IntraLase laser

3
Methods 1

• Hyperopic patients undergoing wavefront LASIK
  with the BL 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

4
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

Results 1

• 114 eyes (56 right eyes)
• 59 patients (33 male)
• Age 527 years (range 38 to 65)
• Preoperative MSE 2.110.82 D (range 0.75 to
  4.00)
• Preoperative Sphere 2.470.87 D (range 1.00 to
  4.25 D)
• Preoperative Cylinder -0.700.40 D (range -0.25
  to -2.50 D)
• Time of discharge 8.33 months (range 3 to 22)

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
