Abstract Details



Purpose:

To evaluate ablation depth with the intraoperative optical coherence pachymetry (OCP) during myopic LASIK surgery.

Setting:

Prospective series of 59 eyes of 32 patients operated on with the Alcon refractive suite equipped with OCP.

Methods:

Corneal thickness was measured before and after the ablation.

Results:

Mean stromal depth was 20.68 m/D with a 6.5 mm optical zone , and 15.79 m/D with a 6.00 mm optical zone . We found a good correlation between attempted correction and ablation depth (0.756; p<0.05).

Conclusions:

Intraoperative online pachymetry enabled the measurement of stromal ablation depth during LASIK. A larger series of patients is necessary to validate our preliminary clinical results. FINANCIAL INTEREST: NONE
