• Lasek Description: This video shows a typical lasek procedure where after topical anesthesia is applied and lid speculum is correctly collocated, the cornea is marked (just one or two marked are necessary) and an alcohol dispenser is attached on the cornea surface, I prefer to use a PRK marker of 8 mm. 20% Alcohol solution is applied for 40 seconds and then is absorbed using a Merocel dry sponges. This procedure could be repeated if you consider that epithelium is still attached to the Bowman Membrane, in this case, the time advised is 10 seconds. A LASIK spatula is inserted under the epithelium to delineate the epithelial margin and then with a wet Merocel sponge, epithelium detachment is performed leaving a hinge. Epithelium removal is easy and reliable, starting by the periphery and always trying to protect the center of the stromal bed in order to avoid an overcorrection produced for the stromal bed dryness. Surface is dried and ablation applied. A generous irrigation is advisable and epithelium replacement is done with a merocel sponge too, irrigating again to avoid detritus on the interfase and ensure a correct alignment of flap. I like to wait three minutes to achieve a correct dryness. Antibiotic and steroids drops and then a soft contact lens. In my personal opinion, specialized instruments are not necessary, but we must to be very careful with the handling of the flap. Otherwise, remember that the possibility to convert in PRK always is a possibility when epithelium flap complications appears.
