Abstract

PURPOSE

To study the outcomes of LASIK after intended thin flap creation using the SCHWIND Carriazo-Pendular microkeratome with the 90-µm head.

METHODS

Forty-seven eyes of 26 patients (mean age 28.78±6.98 years) underwent LASIK with a superior hinge flap using the 90-µm head of the SCHWIND Carriazo-Pendular microkeratome. Evaluation included flap parameters (thickness, diameter, hinge size), complications, and visual outcome.

RESULTS

No intraoperative or early postoperative complications were observed. The mean flap thickness was 79.88±6.94 µm (range: 70 to 93 µm). Mean flap diameter was 9.25±0.45 mm (range: 8.5 to 11 mm) whereas mean hinge size was 4.63±0.66 mm (range: 3 to 6.5 mm). No eye lost lines of best spectacle-corrected visual acuity, and all eyes were emmetropic within one diopter postoperatively.

CONCLUSIONS

The SCHWIND Carriazo-Pendular microkeratome with the 90-µm head seems to have increased accuracy in intended creation of thin flaps. [J Refract Surg. 2009;25:33-36.]
