Comparison of Patient Profiles Wavefront-Guided
LASIK Versus Conventional LASIK

• Michiho Suzuki-Judge, MD
• Inouye Eye Hospital
• Tokyo, Japan

2
Purpose

• To document profiles of patients who selected
  either wavefront-guided LASIKor conventional
  LASIK.

3
Methods

• Records of 396 LASIK procedures from 199 patients
  at Inouye Eye Hospital between 11/06 and 06/07
  were reviewed.
• Tx VISX S4IR
• 79 males and 120 females
• Age range 20 to 57 (33.6?8.4)
• Pre-op spherical equivalent range -0.88 to
  -12.88D (-5.38?2.02)

4
Methods

• All patients were informed of pros, cons and
  price differences between the procedures and made
  their own decisions.

Wavefront-guided Conventional
Pros Less HOA Less night glare Less tissue ablation
Cons More tissue ablation More HOA More night glare
Price 300,000JPY for both eyes (3,000 USD) 200,000JPY for both eyes (2,000 USD)
5
Methods

• Patient data was categorized by age, sex,
  occupation and pre-op refraction for comparative
  analysis.
• X2, ANOVA and T-test analyses were applied to the
  data.

Conclusions

• At our hospital in Tokyo, wavefront-guided to
  conventional LASIK ratio was 63.6 to 36.4.
• Average age and sex were not determinant factors
  in patients decisions for level of LASIK
  treatment.
• Patients in their late 20s and 30s chose
  wavefront-guided LASIK more than conventional
  LASIK.

11
Conclusions

• Patients in their early 20s chose conventional
  LASIK more often.
• Housewives and students (dependants) chose
  conventional LASIK more often.
• High myopia patients chose conventional LASIK
  because they were made aware of concerns for
  opportunities of enhancement if needed.
