Lasik flap folds can induce irregular astigmatism with optical aberrations and loss of BCVA especially if they involve the visual axis. ‘Macrofolds’ are easily seen by slitlamp exam and represent full thickness flap tenting in a linear fashion. On the other hand, ‘microfolds’ within the flap itself may represent wrinkles in Bowman’s layer or in the epithelial basement membrane. They are best seen as negative staining lines with sodium fluorescein. The incidence of folds requiring intervention ranges between 0.2% and 1.5%. (more…)

There comes a time in every laser eye surgical procedure when leaving the battlefield is the best of two (or more) evils. When is it best to reposition the flap, abandon the procedure and possibly attempt the LASIK procedure at a later time…? (more…)

State of the art LASIK technology avoids the following problems during quality laser eye surgery

The Sliding Suction Ring

Application of adequate suction is essential for intraocular pressure upsurge and dissection of good quality corneal flaps. On occasion, the suction ring slides prior to the buildup of adequate vacuum and the flap is decentered from the pupillary axis. This is reported to happen more frequently with the Hansatome microkeratome due to a slower rise in vacuum. Applying equal downwards pressure on the ring through its handle and at the base knob for about 3 seconds prior to initiating vacuum has minimized this problem. (more…)
