Purpose:To report our experience in preventing post-LASIK Diffuse Lamellar Keratitis (DLK) by whipping the microkeratome blade with 100% Alcohol. Methods:Twenty four patients (48 eyes) had Laser in situ Keratomileusis (LASIK) surgery on the same day, by a single surgeon. The same setup and instrumentations were used in all cases. The same blade was used for both eyes of the same patient. All blades were from the same batch manufactured by the Bausch & Lomb Company. Randomly assigned, prior to mounting into the Hansatome microkeratome; 12 blades were whipped with a weck-cell dipped in 100% Alcohol and rinsed with BSS solution (Alcohol group). 12 blades were whipped with a weck-cell dipped in BSS solution and rinsed with BSS solution (control group). Both authors examined all patients on the first postoperative day. Results:Grade 1 - 2 DLK was diagnosed in 7 eyes of 4 patients in the control Group (29%). No DLK was diagnosed in the Alcohol group. Conclusion:Whipping the microkeratome blade with 100% Alcohol prior to mounting may remove a residual substance left from the manufacturing or sterilization process of the blades that may cause DLK.
